Organization and Basis of Presentation	'
	1. Organization and Basis of Presentation
	CrossAmerica Partners LP (formerly Lehigh Gas Partners LP) (the “Partnership”) engages in:
		•	the wholesale distribution of motor fuels (generally using unrelated third party transportation service providers) to sub-wholesalers, independent dealers, lessee dealers and Lehigh Gas—Ohio, LLC, an affiliate (“LGO”);
		•	the retail distribution of motor fuels to end customers at sites operated by commission agents;
		•	the owning or leasing of sites used in the retail distribution of motor fuels and, in turn, generating rent income from the lease or sublease of the sites to third parties or LGO; and
		•	the operation of convenience stores and branded, quick-service restaurants.
	The Partnership’s primary operations are conducted by the following consolidated, wholly-owned subsidiaries:
		•	Lehigh Gas Wholesale LLC (“LGW”), which distributes motor fuels on a wholesale basis;
		•	LGP Realty Holdings LP (“LGPR”), which functions as the real property holding company of the Partnership; and
		•	Lehigh Gas Wholesale Services, Inc. (“LGWS”), which owns and leases (or leases and sub-leases) real estate and personal property used in the retail distribution of motor fuels as well as provides maintenance and other services to lessee dealers and other customers (including LGO). LGWS also distributes motor fuels on a retail basis to end customers at commission sites and, effective April 30, 2014, Petroleum Marketers, Inc. (“PMI”), a subsidiary of LGWS, operates convenience stores and branded quick-service restaurants.
	LGO is an operator of retail motor fuel stations that purchases all of its motor fuel requirements from the Partnership on a wholesale basis in accordance with the Petroleum Marketing Practices Act (“PMPA”) Franchise Agreement between LGO and LGW. LGO also leases motor fuel stations from the Partnership in accordance with a master lease agreement between LGO and the Partnership. The financial results of LGO are not consolidated with those of the Partnership. For more information regarding the Partnership’s relationship with LGO, see Note 18.
	The Partnership was founded in 2012 and completed its initial public offering (“IPO”) on October 30, 2012. In connection with the IPO, Dunne Manning Inc. and its subsidiaries and affiliates, formerly known as Lehigh Gas Corporation (“DMI”), contributed a part of their business, which we refer to as the “Predecessor Entity,” to the Partnership.
	On October 1, 2014, the Partnership and CST Brands, Inc. (together with its affiliates, “CST”) announced the consummation of the previously announced sale to CST of the Partnership’s General Partner, Lehigh Gas GP LLC (the “General Partner”), from DMI, an entity wholly owned by the 2004 Irrevocable Trust of Joseph V. Topper, Sr. (the “Topper Trust”) for which Joseph V. Topper, Jr. is the trustee, and all of the membership interests in limited liability companies formed by trusts for which each of Mr. Topper and John B. Reilly, III serves as trustee, which limited liability companies own all of the incentive distribution rights (“IDRs”) (the “General Partner Acquisition”). CST is one of the largest independent retailers of motor fuels and convenience merchandise in North America.
	The General Partner manages the operations and activities of the Partnership. The Partnership is managed and operated by the board of directors and executive officers of the General Partner. As a result of the consummation of the General Partner Acquisition, CST controls the General Partner and has the right to appoint all members of the board of directors of the General Partner.
	Immediately following the consummation of the General Partner Acquisition, the Partnership changed its name to “CrossAmerica Partners LP” and began trading on the New York Stock Exchange under the symbol CAPL.
	See Note 20 for additional information.
	Interim Financial Statements
	The accompanying interim condensed consolidated financial statements and related disclosures are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) on the same basis as the corresponding audited financial statements for the year ended December 31, 2013, and in the opinion of management, include all adjustments of a normal recurring nature considered necessary to present fairly the Partnership’s financial position as of September 30, 2014, and the results of its operations and cash flows for the periods presented. Operating results for the three and nine months ended September 30, 2014, are not necessarily indicative of the results that may be expected for the year ending December 31, 2014, or any other future periods. The balance sheet as of December 31, 2013, was derived from the consolidated financial statements for the year ended December 31, 2013. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted under the Securities and Exchange Commission’s (“SEC”) rules and regulations for interim financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the corresponding audited consolidated financial statements and accompanying notes for the year ended December 31, 2013, included in the Partnership’s Annual Report on Form 10-K, filed with the SEC.
	Reclassifications
	Certain reclassifications were made to prior period amounts to conform to the current year presentation. These reclassifications had no impact on net income or equity for any periods.

Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	2. Summary of Significant Accounting Policies
	Revenue Recognition
	Revenues from wholesale fuel sales are recognized when fuel is delivered to the customer. Revenues from retail fuel sales are recognized when fuel is sold to the customer. Substantially all revenues from fuel sales are from sales of gasoline, with the remainder comprised of diesel and other products.
	Revenues from leasing arrangements in which the Partnership is the lessor are recognized ratably over the term of the underlying lease.
	Retail food and merchandise sales are recognized net of applicable provisions for discounts and allowances upon delivery, generally at the point of sale.
	Inventory
	Motor fuel inventory consists of gasoline, diesel fuel and other petroleum products and is stated at the lower of average cost or market using the first-in, first-out method. No provision for potentially obsolete or slow-moving inventory has been made. The Partnership records inventory from the time of the purchase of motor fuels from third party suppliers until the retail sale to the end customer.
	Food and merchandise inventory is valued at the lower of cost or market using the first-in, first-out method.
	Asset Retirement Obligations
	The Partnership is obligated by contractual or regulatory requirements or contingently obligated at the discretion of the lessor to remove certain equipment, such as underground gasoline storage tanks, or perform other remediation upon retirement of certain assets at sites at which the Partnership is the lessee. Certain states statutorily require removal of the underground storage tanks at a certain point in time. An asset retirement obligation is recognized in the period incurred, which is generally either at the time of lease inception or at the time a decision is made to close a site. Determination of the amounts recognized is based on numerous estimates and assumptions, including expected settlement dates and probability of occurrence, future retirement costs, future inflation rates and credit-adjusted risk-free rates. The Partnership’s asset retirement obligations, which are primarily included in other long-term liabilities in the balance sheets, totaled $2.0 million and $2.2 million at September 30, 2014 and December 31, 2013, respectively.
	Asset Impairment
	The Partnership reviews long-lived assets, including property and equipment and intangible assets other than goodwill, for impairment when events or changes in circumstances indicate the carrying amount of the long-lived asset (group) might not be recoverable in accordance with ASC 360, “Impairment or Disposal of Long-Lived Assets.” Such events and circumstances include, among other factors: operating losses; market value declines; changes in the expected physical life of an asset; changes in business plans or those of major customers, suppliers or other business partners; changes in competition and competitive practices; uncertainties associated with the U.S. and world economies; changes in the expected level of capital, operating or environmental remediation expenditures; and changes in governmental regulations or actions. The impairment evaluation is initially based on the projected undiscounted cash flows of the asset (group), including residual value upon eventual disposition. If the projected undiscounted cash flows of the asset (group) are less than its carrying value, the impairment loss is measured by comparing the present value of the future cash flows associated with the asset (group) to its carrying value and is recorded at that time.
	New Accounting Guidance
	Discontinued Operations
	In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of an Entity, which revises the criteria to qualify as a discontinued operation and requires new disclosures. Under this guidance, a discontinued operation is (1) a component of an entity or group of components that has been disposed of or classified as held for sale that represents a strategic shift that has or will have a major effect on an entity’s operations and financial results or (2) an acquired business that is classified as held for sale on the date of acquisition. This guidance also permits companies to have continuing cash flows and significant continuing involvement with the disposed component.
	The Partnership disposes of individual sites or groups of sites from time to time that generally do not represent a strategic shift and generally do not have a major effect on operations or financial results. As a result of this new guidance, these disposals will generally not meet the criteria for recognition as a discontinued operation. The Partnership has early adopted this guidance on a prospective basis effective January 1, 2014.
	Revenue Recognition
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which clarifies the principles for recognizing revenue and develops a common revenue standard under U.S. GAAP and International Financial Reporting Standards. Specifically, the core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services.
	This guidance is effective January 1, 2017, and provides for modified retrospective transition. Management is currently evaluating the impact of adopting this guidance.

	3. Acquisitions
	PMI Acquisition
	On April 28, 2014, the Partnership exercised an option (“Option”) to purchase 100% of the membership interests of Pinehurst Petroleum, LLC (“Pinehurst”) from Joseph L. Smith III and John A. Kopfer, Jr. (“Smith/Kopfer”) for $4.0 million. Pinehurst’s sole asset was an Agreement and Plan of Merger among Pinehurst, PMI Merger Sub, Inc., a wholly-owned subsidiary of Pinehurst (“Sub”), Petroleum Marketers, Incorporated, (“PMI”), Petroleum Marketers, Incorporated Employee Stock Ownership Trust and Ronald R. Hare, in his capacity as representative (the “Merger Agreement”) pursuant to which Pinehurst agreed to acquire all of the shares of PMI for $73.5 million inclusive of an adjustment for working capital, through the merger (the “Merger”) of Sub and PMI. Under the terms of the Merger Agreement, the stockholders of PMI agreed to escrow $5.0 million for 25 months after the closing date to secure the indemnity provisions contained in the Merger Agreement for the benefit of Pinehurst. The Merger Agreement also contains customary representations, warranties, agreements and obligations of the parties, and termination, closing conditions and indemnity provisions. The transaction was funded with borrowings under the Partnership’s Credit Facility. On April 30, 2014, pursuant to the Option, the Partnership purchased all of the equity interests of Pinehurst ($1.0 million of the consideration has been included in accrued expenses and other current liabilities at September 30, 2014). Subsequent to such purchase, the Merger became effective and, as a result, the Partnership became the owner of PMI. The exercise of the Option and the Merger is referred to as the PMI Transaction.
	The acquisition augmented the Partnership’s presence in Virginia and complements the existing Tennessee operations. PMI operates two primary lines of business: convenience stores and petroleum products distribution. In its convenience store business, PMI operates 87 convenience stores and nine co-located branded quick service restaurants located in Virginia and West Virginia. The convenience stores distribute primarily branded fuel and operate under PMI’s own proprietary convenience store brand, “Stop in Food Stores.” The petroleum products business distributes motor fuels and other petroleum products to customers throughout Virginia, West Virginia, Tennessee and North Carolina.
	On May, 1, 2014, immediately subsequent to the effectiveness of the Merger, the Partnership caused PMI to divest its lubricants business (the “Lubricants Business”) to Zimri Holdings, LLC (“Zimri”), an entity owned by Smith/Kopfer for the sum of $14.0 million pursuant to an Asset Purchase Agreement (“APA”) between PMI and Zimri. The APA contains customary representations, warranties, agreements and obligations of the parties, as well as indemnity provisions. A trust controlled by Joseph V. Topper, Jr, Chairman and CEO of the general partner of the Partnership at the time, financed the purchase of the Lubricants Business by Zimri pursuant to a loan to Zimri. The financing by Mr. Topper’s trust was approved by the former Conflicts Committee of the board of directors of the general partner of the Partnership.
	The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed at the acquisition date, the fair value of the net assets divested as part of the Lubricants Business and the preliminary fair values of the assets acquired and liabilities assumed net of the divestiture (in thousands):

	The fair value of inventory was estimated at retail selling price less costs and a reasonable profit allowance for the selling effort.
	The above fair values of assets and liabilities acquired are provisional and based on information that was available as of the acquisition date. The Partnership believes the information provides a reasonable basis for estimating the fair values. The purchase price allocation is preliminary pending a final valuation of the assets and liabilities, including a final valuation of property and equipment, intangible assets and the impact of income taxes. Thus, the provisional measurements of fair value reflected are subject to change, and such change could be significant. The Partnership expects to finalize the valuation and complete the accounting for the transaction as soon as practicable, but no later than one year from the acquisition date.
	The fair value of land, buildings, and equipment was based on a cost approach, with the fair value of an asset estimated by reference to the replacement cost to obtain a substitute asset of comparable features and functionality, and is the amount a willing market participant would pay for such an asset, taking into consideration the asset condition as well as any physical deterioration, functional obsolescence, and/or economic obsolescence. The buildings and equipment are being depreciated on a straight-line basis, with estimated useful lives of 20 years for buildings and 5 to 15 years for equipment.
	The $15.0 million fair value of the wholesale fuel supply agreements was based on an income approach, with the fair value estimated to be the present value of incremental after-tax cash flows attributable solely to the wholesale fuel supply agreements over their estimated remaining useful life, using probability-weighted cash flows, generally assumed to extend through the term of the wholesale fuel supply contracts, and using discount rates considered appropriate given the inherent risks associated with this type of agreement. Management believes the level and timing of cash flows represent relevant market participant assumptions. The wholesale fuel supply agreements are being amortized on a straight-line basis over an estimated useful life of approximately 10 years.
	Goodwill recorded is primarily attributable to the deferred tax liabilities arising from the application of purchase accounting.
	Aggregate incremental revenues since the closing of the PMI Transaction included in the Partnership’s statement of operations were $246.9 million and $420.7 million for the three and nine months ended September 30, 2014, respectively.

	Atlas Acquisition
	On May 19, 2014, the Partnership completed its acquisition of 52 wholesale supply contracts, one sub-wholesaler contract, nine fee sites, six leasehold sites and certain other assets from affiliates of Atlas Oil Company (“Atlas”) for $34.0 million. In addition, the Partnership acquired certain short-term notes receivable associated with the wholesale supply and commission marketing contracts for $5.2 million, bringing total consideration to $39.2 million, subject to closing adjustments. The transaction was funded by borrowings under the Partnership’s Credit Facility and $4.0 million of proceeds from the sale of the Lubricants Business that were directed to an escrow agent as part of a Section 1031 like-kind exchange.
	These assets are located in the Chicago, Illinois area and are branded BP. The wholesale supply contracts have a remaining average term of 15 years and the fee or leasehold sites are currently leased to third party commission agents. The short-term notes receivable relate to previously negotiated purchase agreements of certain sites by the dealers occupying the locations. All of the notes receivable relate to sites supplied under contracts acquired in this transaction. The notes receivable have a weighted average maturity of June 2015.
	In connection with the acquisition, Sam Simon, Chairman and Chief Executive Officer of Atlas Oil Company, entered into a non-compete agreement that generally restricts him and entities controlled by him from (a) engaging in the wholesale distribution of motor fuel or owning or operating a retail motor fuel facility and/or convenience store within certain territories for one year after the closing date, and (b) constructing any new retail motor fuel facility and/or convenience stores within certain territories for five years after the closing date.

	The above fair values of assets and liabilities acquired are provisional and based on information that was available as of the acquisition date. The Partnership believes the information provides a reasonable basis for estimating the fair values. The purchase price allocation is preliminary pending a final valuation of the assets and liabilities, including a final valuation of property and equipment, intangible assets and the impact of income taxes. Thus, the provisional measurements of fair value reflected are subject to change, and such change could be significant. The Partnership expects to finalize the valuation and complete the accounting for the transaction as soon as practicable, but no later than one year from the acquisition date.
	The fair value of land, buildings, and equipment was based on a cost approach, with the fair value of an asset estimated by reference to the replacement cost to obtain a substitute asset of comparable features and functionality, and is the amount a willing market participant would pay for such an asset, taking into consideration the asset condition as well as any physical deterioration, functional obsolescence, and/or economic obsolescence. The buildings and equipment are being depreciated on a straight-line basis, with estimated useful lives of 20 years for buildings and 5 to 15 years for equipment.
	The approximate $15.4 million fair value of the wholesale fuel supply agreements was based on an income approach, with the fair value estimated to be the present value of incremental after-tax cash flows attributable solely to the wholesale fuel supply agreements over their estimated remaining useful life, using probability-weighted cash flows, generally assumed to extend through the term of the wholesale fuel supply contracts, and using discount rates considered appropriate given the inherent risks associated with this type of agreement. Management believes the level and timing of cash flows represent relevant market participant assumptions. The wholesale fuel supply agreements are being amortized on an accelerated basis over an estimated useful life of approximately 10 years.
	The approximate $2.2 million fair value of the wholesale fuel distribution rights was based on an income approach, with the fair value estimated to be the present value of incremental after-tax cash flows attributable solely to the wholesale fuel distribution rights over their estimated remaining useful life, using probability-weighted cash flows, using discount rates considered appropriate given the inherent risks associated with this type of transaction. Management believes the level and timing of cash flows represent relevant market participant assumptions. The wholesale fuel distribution rights are being amortized on a straight-line basis over an estimated useful life of approximately 10 years.
	The approximate $0.6 million fair value of the covenant not to compete was based on an income approach, with the fair value estimated to be the difference between the present value of after-tax cash flows with and without the covenant not to compete in place, using probability-weighted cash flows, using discount rates considered appropriate given the inherent risks associated with this type of transaction. Management believes the level and timing of cash flows represent relevant market participant assumptions. The covenant not to compete intangible asset is being amortized on a straight-line basis over a 5-year period.
	The approximate $0.4 million fair value of the discount related to lease agreements with below average market value and the $1.3 million fair value of the discount related to lease agreements with above average market value were based on an income approach, with the fair value estimated to be the present value of incremental after-tax cash flows attributable solely to the lease agreements over their estimated remaining useful life, generally assumed to extend through the term of the lease agreements, and using discount rates considered appropriate given the inherent risks associated with this type of agreement. The Partnership believes the level and timing of cash flows represent relevant market participant assumptions. The discount related to lease agreements with above/below average market value is being amortized on a straight-line basis over the term of the respective lease agreements, with an estimated weighted average useful life of 5 years.
	Aggregate incremental revenues for the acquisition since the acquisition date included in the Partnership’s statements of operations were $60.7 million and $89.1 million for the three and nine months ended September 30, 2014, respectively.
Acquisition Costs
Acquisition costs totaled $0.1 million and $0.4 million for the three months ended September 30, 2014 and 2013 and $6.1 million and $1.0 million for the nine months ended September 30, 2014 and 2013, respectively. Such costs are included in selling, general and administrative expenses.

	Credit Facility
	In March 2014, the Partnership entered into an amended and restated credit agreement, which was amended and restated on September 30, 2014 (the “Credit Facility”). The Credit Facility is a senior secured revolving credit facility maturing on March 4, 2019, with a total borrowing capacity of $550.0 million, under which swing-line loans may be drawn up to $10.0 million and standby letters of credit may be issued up to an aggregate of $45.0 million. The Credit Facility may be increased, from time to time, upon the Partnership’s written request, subject to certain conditions, up to an additional $100.0 million. All obligations under the Credit Facility are secured by substantially all of the assets of the Partnership and its subsidiaries. The notional amount of availability at September 30, 2014, was $388.1 million. As a result of the composition of lenders changing with this amendment, deferred financing costs of $0.3 million were written off during the three months ended September 30, 2014.
	Borrowings under the Credit Facility bear interest, at the Partnership’s option, at (1) a rate equal to the London Interbank Offering Rate (“LIBOR”), for interest periods of one week or one, two, three or six months, plus a margin of 2.00% to 3.25% per annum, depending on the Partnership’s total leverage ratio (as defined) or (2) (a) a base rate equal to the greatest of: (i) the federal funds rate, plus 0.5%, (ii) LIBOR for one month interest periods, plus 1.00% per annum or (iii) the rate of interest established by the agent, from time to time, as its prime rate, plus (b) a margin of 1.00% to 2.25% per annum depending on the Partnership’s total leverage ratio. In addition, the Partnership incurs a commitment fee based on the unused portion of the revolving credit facility at a rate of 0.35% to 0.50% per annum depending on the Partnership’s total leverage ratio. The weighted-average interest rate on outstanding borrowings at September 30, 2014, was 3.5%. Letters of credit outstanding at September 30, 2014, and December 31, 2013, totaled $16.4 million and $12.3 million, respectively.
	The Partnership is required to comply with certain financial covenants under the Credit Facility. Effective July 2, 2014, the Partnership is required to maintain a total leverage ratio (as defined) for the most recently completed four fiscal quarters of less than or equal to 5.50:1.00 for the period of April 1, 2014, through September 30, 2014; and 5.00:1.00 for the period of October 1, 2014, through December 31, 2014, and 4.50:1.00 for periods thereafter, except for periods following a material acquisition. However, if an offering of Equity Interests (as defined) in the Partnership occurs after July 2, 2014, but prior to December 31, 2014, the total leverage ratio shall not exceed 4.50:1.00 for the fiscal quarter ending December 31, 2014; and the total leverage ratio shall not exceed 5.00:1.00 for the first two full fiscal quarters following the closing of a material acquisition or 5.50 : 1:00 upon the issuance of Qualified Senior Notes (as defined) in the aggregate principal amount of $175.0 million or greater. The Partnership is also required to maintain a senior leverage ratio (as defined) after the issuance of Qualified Senior Notes of $175.0 million or greater of less than or equal to 3.00:1.00 and a consolidated interest coverage ratio (as defined) of at least 2.75 to 1.00.
	The Credit Facility prohibits the Partnership from making distributions to its unitholders if any potential default or event of default occurs or would result from the distribution, or the Partnership is not in compliance with its financial covenants. In addition, the Credit Facility contains various covenants which may limit, among other things, the Partnership’s ability to grant liens; create, incur, assume, or suffer to exist other indebtedness; or make any material change to the nature of the Partnership’s business, including mergers, liquidations, and dissolutions; and make certain investments, acquisitions or dispositions.

	Operating Leases of Sites as Lessee
	The Partnership leases sites from third parties under certain non-cancelable operating leases that expire from time to time through 2028.
	The future minimum lease payments under operating leases as of September 30, 2014, were as follows (in thousands):
	Remaining in 2014	$	5,880
	2015		17,814

	Total future minimum lease payments	$	135,434
	The future minimum lease payments presented above do not include contingent rent based on future inflation, future revenues or volumes, or amounts that may be paid as reimbursements for certain operating costs incurred by the lessor. Most lease agreements include provisions for renewals.
	Getty Lease
	In May 2012, the Predecessor Entity entered into a 15-year master lease agreement with renewal options of up to an additional 20 years with Getty. Pursuant to the lease, the Predecessor Entity leased 105 gas station sites in Massachusetts, New Hampshire and Maine (the “New England Sites”). The lease was assigned to the Partnership in November 2012 and has been amended to add an additional 25 sites in New Jersey and one site in Delaware and one site in Maryland. The Partnership pays fixed rent, which increases 1.5% per year. In addition, the lease requires contingent rent payments based on gallons of fuel sold. During the initial three years of the lease, the Partnership is required to make capital expenditures of at least $4.3 million plus $0.01 per gallon of fuel sold at the New England Sites. However, the Partnership is entitled to a rent credit equal to 50% of the capital expenditures up to a maximum of $2.1 million. During the initial 3.5 years of the lease, the Partnership is required to make capital expenditures of at least $1.0 million at the New Jersey sites.
	Because the fair value of the land at lease inception was estimated to represent more than 25.0% of the total fair value of the real property subject to the lease, the land element of the lease was analyzed for operating or capital treatment separately from the rest of the property subject to the lease. The land element of the lease was classified as an operating lease and all of the other property was classified as a capital lease. As such, future minimum lease payments are included in both the lease financing obligations and operating lease tables above.
	Through September 30, 2014, eight sites have been terminated from the lease and the Partnership notified Getty of its intent to terminate six additional sites from the lease. Any property and equipment or lease financing obligations associated with these sites were removed from the balance sheet, which resulted in a gain of $0.2 million and $0.3 million for the three months ended September 30, 2014 and 2013 and $0.3 million and $0.3 million for the nine months ended September 30, 2014 and 2013, respectively, which is classified as a reduction of rent expense.
	Operating Leases of Sites as Lessor
	Motor fuel stations are leased to tenants under operating leases with various expiration dates ranging through 2028.
	The future minimum lease payments under non-cancelable operating leases with third parties and operating leases with LGO as of September 30, 2014, were as follows (in thousands):

	The future minimum lease payments presented above do not include contingent rent based on future inflation, future revenues or volumes of the lessee, or amounts that may be received as tenant reimbursements for certain operating costs. Most lease agreements include provisions for renewals.
	On May 28, 2014, the Partnership entered into a Master Lease Agreement (the “Lease”) with LGO, with an effective date of June 1, 2014 which consolidated all of the individual leases then in effect into a single master lease. The terms and conditions of the Lease are substantially identical to the existing individual leases except as follows: the Partnership’s right to terminate each lease was deleted, and in its place, each party has the right to either sever, in the case of LGO, up to 7.0% of the leased premises each year, or recapture, in the case of the Partnership, up to 5.0% of the leased premises each year from the Lease at any time prior to the fifth anniversary of the commencement date (as defined) for such leased premises. Each party’s right is cumulative in that if a party does not sever or recapture, as applicable, the full amount of leased premises for which it has rights, then the non-utilized amount may be carried forward into subsequent years. The Lease was approved by the former Conflicts Committee of the general partner of the Partnership.

Environmental Remediation Obligations [Abstract]	'
Environmental Matters	'
	11. Environmental Matters
	The Partnership currently owns or leases sites where refined petroleum products are being or have been handled. These sites and the refined petroleum products handled thereon may be subject to federal and state environmental laws and regulations. Under such laws and regulations, the Partnership could be required to remove or remediate containerized hazardous liquids or associated generated wastes (including wastes disposed of or abandoned by prior owners or operators), to remediate contaminated property arising from the release of liquids or wastes into the environment, including contaminated groundwater, or to implement best management practices to prevent future contamination.
	The Partnership maintains insurance of various types with varying levels of coverage that is considered adequate under the circumstances to cover operations and properties. The insurance policies are subject to deductibles that are considered reasonable and not excessive. In addition, the Partnership has entered into indemnification and/or escrow agreements with various sellers in conjunction with several of their respective acquisitions, as further described below. Financial responsibility for environmental remediation is negotiated in connection with each acquisition transaction. In each case, an assessment is made of potential environmental liability exposure based on available information. Based on that assessment and relevant economic and risk factors, a determination is made whether to, and the extent to which the Partnership will, assume liability for existing environmental conditions.
	The table below presents a rollforward of the Partnership’s environmental liability for the nine months ended September 30, 2014 and 2013, (in thousands):
		2014			2013
	Beginning balance	$	1,238		$	1,177

	Ending balance		1,486			1,394
	Current portion		601			424
	Long-term portion	$	885		$	970
	At September 30, 2014, the Partnership was indemnified by third-party escrow funds, state funds or insurance totaling $1.5 million, which were recorded as indemnification assets. State funds represent probable state reimbursement amounts. Reimbursement will depend upon the continued maintenance and solvency of the state. Insurance coverage represents amounts deemed probable of reimbursement under insurance policies.
	The estimates used in these liabilities were based on all known facts at the time and an assessment of the ultimate remedial action outcomes. The Partnership will adjust loss accruals as further information becomes available or circumstances change. Among the many uncertainties that impact the estimates are the necessary regulatory approvals for, and potential modifications of remediation plans, the amount of data available upon initial assessment of the impact of soil or water contamination, changes in costs associated with environmental remediation services and equipment and the possibility of existing legal claims giving rise to additional claims.
	Environmental liabilities related to the contributed sites have not been assigned to the Partnership, and are still the responsibility of the Predecessor Entities (see the Annual Report on Form 10-K for the year ended December 31, 2013, for additional discussion of the Predecessor Entities). Under the Amended and Restated Omnibus Agreement among the Partnership, DMI, LGO, Mr. Topper, and CST (the “Omnibus Agreement”), certain of the Predecessor Entities must indemnify the Partnership for any costs or expenses that the Partnership incurs for environmental liabilities and third-party claims, regardless of when a claim is made, that are based on environmental conditions in existence prior to the closing of the IPO for contributed sites. Certain of the Predecessor Entities are beneficiaries of escrow accounts created to cover the cost to remediate certain environmental liabilities. In addition, certain of the Predecessor Entities maintain insurance policies to cover environmental liabilities and/or, where available, participate in state programs that may also assist in funding the costs of environmental liabilities. Certain sites that were contributed to the Partnership were identified as having existing environmental liabilities that are not covered by escrow accounts, state funds or insurance policies. For more information on the Omnibus Agreement, see Note 20.
	The table below presents a rollforward of the Predecessor Entities’ environmental liability for the nine months ended September 30, 2014, (in thousands):

	Changes in estimates for previously incurred losses		(627	)
	Payments		(2,305	)

	Purchase Commitments
	The future minimum volume purchase requirements under the existing supply agreements are approximate gallons, with a purchase price at prevailing market rates for wholesale distribution. The following provides total future minimum volume purchase requirements (in thousands of gallons) for the following years:
	Remaining in 2014	103,357
	2015	377,130
	2016	316,979
	2017	256,755
	2018	242,089
	Thereafter	2,540,753
	Total	3,837,063
	In the event the Partnership fails to purchase the required minimum volume during any given contract year, the underlying third party’s exclusive remedies (depending on the magnitude of the failure) are generally termination of the supply agreement and, in some instances to a lesser extent, a financial penalty per gallon based on the volume shortfall for the given year.
	Legal Matters
	In the normal course of business, the Partnership has and may become involved in legal actions relating to the ownership and operation of its properties and business. In management’s opinion, the resolutions of any such pending legal actions are not expected to have a material adverse effect on its financial position, results of operations and cash flows. The Partnership maintains liability insurance on certain aspects of its businesses in amounts deemed adequate by management. However, there is no assurance that this insurance will be adequate to protect it from all material expenses related to potential future claims or these levels of insurance will be available in the future at economically acceptable prices.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	13. Fair Value Measurements
	The Partnership measures and reports certain financial and non-financial assets and liabilities on a fair value basis. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). GAAP specifies a three-level hierarchy that is used when measuring and disclosing fair value. The fair value hierarchy gives the highest priority to quoted prices available in active markets (i.e., observable inputs) and the lowest priority to data lacking transparency (i.e., unobservable inputs). An instrument’s categorization within the fair value hierarchy is based on the lowest level of significant input to its valuation. The following is a description of the three hierarchy levels.
	Level 1	Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Active markets are considered to be those in which transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
	Level 2	Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability. This category includes quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in inactive markets.
	Level 3	Unobservable inputs are not corroborated by market data. This category is comprised of financial and non-financial assets and liabilities whose fair value is estimated based on internally developed models or methodologies using significant inputs that are generally less readily observable from objective sources.
	Transfers into or out of any hierarchy level are recognized at the end of the reporting period in which the transfers occurred. There were no transfers between any levels in 2014 or 2013.
	As further discussed in Note 15, the Partnership has accrued for phantom units and profits interests granted as a liability and adjusts that liability on a recurring basis based on the market price of the Partnership’s common units each balance sheet date. Such fair value measurements are deemed Level 1 measurements.
	Financial Instruments
	The fair value of the Partnership’s accounts receivable and accounts payable approximated their carrying values as of September 30, 2014, and December 31, 2013, due to the short-term maturity of these instruments. The fair value of the Partnership’s long-term debt approximated its carrying value as of September 30, 2014, and December 31, 2013, due to the frequency with which interest rates are reset based on changes in prevailing interest rates. The fair value of debt, classified as a Level 2 measurement, was estimated using an income approach by discounting future cash flows at estimated current cost of funding rates, which incorporate the credit risk of the Partnership.

	In March 2014, 92,683 common units were issued (net of units withheld for income taxes) to employees of DMI as a result of the vesting of phantom units (see Note 15 for additional information).
	In September 2014, the Partnership issued 4,140,000 common units, inclusive of the underwriter’s over-allotment option, for $33.99 per unit, resulting in proceeds of $135.0 million, net of underwriting discounts and commissions and offering expenses. The Partnership used the proceeds to reduce indebtedness outstanding under its Credit Facility.

Equity-Based Incentive Compensation	'
	15. Equity-Based Incentive Compensation
	In connection with the IPO, the General Partner adopted the Lehigh Gas Partners LP 2012 Incentive Award Plan (the “Plan”), a long-term incentive plan for employees, officers, consultants and directors of the General Partner and any of its affiliates, including DMI, who perform services for the Partnership. The maximum number of common units that may be delivered with respect to awards under the Plan is 1,505,000. Generally, the Plan provides for grants of restricted units, unit options, performance awards, phantom units, profits interests, unit awards, unit appreciation rights, distribution equivalent rights, and other unit-based awards, with various limits and restrictions attached to these awards on a grant-by-grant basis. The Plan is administered by the board of directors of the Partnership’s General Partner or a committee thereof, which is referred to as the Plan Administrator.
	The Plan Administrator may terminate or amend the Plan at any time with respect to any common units for which a grant has not yet been made. The Plan Administrator also has the right to alter or amend the Plan or any part of the Plan from time to time, including increasing the number of common units that may be granted, subject to unitholder approval as required by the exchange upon which common units are listed at that time; however, no change in any outstanding grant may be made that would adversely affect the rights of a participant with respect to awards granted to a participant prior to the effective date of such amendment or termination, except that the board of directors of our General Partner may amend any award to satisfy the requirements of Section 409A of the Internal Revenue Code. The Plan will expire on the tenth anniversary of its approval, when common units are no longer available under the Plan for grants or upon its termination by the Plan Administrator, whichever occurs first.
	In March 2014, the Partnership contributed its investments in its operating subsidiaries and certain other assets and liabilities to LGP Operations LLC (“LGP Operations”), a wholly-owned subsidiary of the Partnership. Also in March 2014, LGP Operations granted profits interests to certain employees of DMI, which are represented by Class B Units in LGP Operations. Upon vesting, Class B Unitholders will be entitled to receive cash distributions proportionate to those received by common unitholders. Class B Units are redeemable two years after they were granted, subject to certain limitations, for cash or common units at the discretion of the board of directors of the General Partner.
	Because the Class B Units are an interest in the equity of LGP Operations, they represent a noncontrolling interest from the perspective of the Partnership. As such, the Class B Units are presented as a noncontrolling interest on the balance sheet and the Class B Unitholders’ interest in the net income of LGP Operations is presented as net income attributable to noncontrolling interests on the statement of operations.
	Awards to Employees of Affiliates
	The following is a summary of the award activity for the nine months ended September 30, 2014.
			Phantom			Profits
			Units			Interests
	Non-vested at beginning of period			433,373			—
	Granted			35,137			18,689
	Forfeited			(4,829	)		—
	Vested (a)			(143,954	)		—
	Non-vested at end of period			319,727			18,689
	(a)	Of the phantom units that vested during the nine months ended September 30, 2014, 51,271 common units were withheld for taxes.
	Awards vest 33.0% on March 15 of the year following the year of grant, 33.0% on March 15 of the second year following the year of grant, and 34.0% on March 15 of the third year following the year of grant.
	The fair value of the non-vested awards outstanding at September 30, 2014, was $11.5 million. Compensation expense for the three months ended September 30, 2014 and 2013 was $1.6 million and $1.2 million, and for the nine months ended September 30, 2014 and 2013 was $3.6 million and $2.2 million, respectively. Unrecognized compensation expense related to the non-vested awards is expected to be recognized over a weighted average period of 1.6 years.
	It is the intent of the Partnership to settle the phantom units upon vesting by issuing common units and to settle the profits interests upon conversion by the grantee by issuing common units, as permitted under the Plan. However, the awards may be settled in cash at the discretion of the board of directors of the General Partner.
	Because the Partnership grants awards to employees of DMI, and because the grants may be settled in cash, the grants are measured at fair value at each balance sheet reporting date and the cumulative compensation cost recognized is classified as a liability, which is included in accrued expenses and other current liabilities on the balance sheet.
	See Note 20 for a discussion of the accelerated vesting of equity-based incentive compensation awards upon the change in control of the General Partner in October 2014 and the October 2014 grant of phantom units.
	Awards to Members of the Board of Directors
	During the nine months ended September 30, 2014, the Partnership also granted the following awards to members of the board of directors of the General Partner as a portion of director compensation:
	Year of service		2013		2014	2014
	Type of Award		Profits Interests		Phantom Units	Profits Interests
	Vesting		100% upon grant		100% on March 15, 2015	100% on March 15, 2015
	Number of Awards		5,948		2,045	9,481
	The fair value of the non-vested awards outstanding at September 30, 2014, was $0.4 million. Unrecognized compensation expense related to the non-vested awards is expected to be recognized through December 31, 2014.
	See Note 20 for a discussion of the accelerated vesting of equity-based incentive compensation awards upon the change in control in October 2014 and the approval of a grant of phantom units that will occur in November 2014.

Income Taxes	'
	16. Income Taxes
	As a limited partnership, the Partnership is not subject to federal and state income taxes. Income tax attributable to the Partnership’s taxable income, which may differ significantly from income for financial statement purposes, is assessed at the individual level of the unitholder. The Partnership is subject to a statutory requirement that non-qualifying income, as defined by the Internal Revenue Code, cannot exceed 10.0% of total gross income for the calendar year. If non-qualifying income exceeds this statutory limit, the Partnership would be taxed as a corporation. The non-qualifying income did not exceed the statutory limit in any period.
	Certain activities that generate non-qualifying income are conducted through the Partnership’s wholly owned taxable corporate subsidiary, LGWS. Current and deferred income taxes are recognized on the earnings of LGWS. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and are measured using enacted tax rates.
	As a result of the recognition of net deferred tax liabilities associated with the preliminary purchase price allocation related to the acquisition of PMI, the Partnership released $5.2 million of its valuation allowance against deferred tax assets in the second quarter of 2014. Since the purchase price allocation is preliminary, such release is subject to change and such change could be material. Further, in conjunction with the Partnership’s ongoing review of its actual results and anticipated future earnings, the Partnership continuously reassesses the possibility of releasing the remaining $1.9 million valuation allowance on its deferred tax assets. It is reasonably possible that a significant portion of the valuation allowance will be released within the next twelve months. The valuation allowance release was partially offset by the impact of certain nondeductible acquisition costs and the taxable gain on the sale of the Lubricants Business for which a portion related to nondeductible goodwill.
	At June 30, 2013, net deferred tax assets totaling $10.4 million were fully reserved against with a valuation allowance. During the third quarter of 2013, based on the updates to the purchase price allocation for the Express Lane acquisition and the assignment of property and equipment by the Partnership to LGWS, the Partnership recorded a net deferred tax liability of $5.9 million. Concurrent with the recognition of this deferred tax liability, and based on the expected reversal of the cumulative temporary differences and anticipated future earnings as of September 30, 2013, the Partnership released $0.9 million and $0.3 million of the valuation allowance during the three and nine months ended September 30, 2013. This release was recorded as a deferred tax benefit, effectively reversing all of the valuation allowance that was recorded to deferred tax expense in 2012 and through June 30, 2013.

Earnings Per Share [Abstract]	'
Net Income per Limited Partnership Unit	'
	17. Net Income per Limited Partnership Unit
	Under the Partnership Agreement, the holder of the Partnership’s IDRs have an interest in distributions from the Partnership that are increasing percentages starting at 15% of quarterly distributions out of the operating surplus (as defined) in excess of $0.5031 per limited partner unit. The Partnership’s undistributed net income is generally allocable pro rata to the common and subordinated unitholders, except where common unitholders have received cash distributions in excess of the subordinated unitholders. In that circumstance, net income is allocated to the common unitholders first in support of such excess cash distribution paid to them and the remainder of the net income is allocable pro rata to the common and subordinated unitholders. Losses are generally allocable pro rata to the common and subordinated unitholders in accordance with the Partnership Agreement unless a loss would create, or increase a Partnership deficit balance, then the loss would be allocated to the General Partner.
	In addition to the common and subordinated units, the Partnership has identified the IDRs as participating securities and computes income per unit using the two-class method under which any excess of distributions declared over net income shall be allocated to the partners based on their respective sharing of income specified in the Partnership Agreement. Net income per unit applicable to limited partners (including common and subordinated unitholders) is computed by dividing the limited partners’ interest in net income, after deducting any incentive distributions, by the weighted-average number of outstanding common and subordinated units. There were no participating IDRs for 2013. However, the distributions declared since March 2014 exceeded the threshold and so IDRs participated in these distributions as summarized on the statements of operations.
	The following provides a reconciliation of net income and the allocation of net income to the limited partners’ interest for purposes of computing net income per limited partner unit for the following periods (in thousands, except unit, and per unit amounts):

	Revenues from Fuel Sales to LGO
	In connection with the IPO, the Partnership and LGO entered into a PMPA Franchise Agreement pursuant to which the Partnership is the exclusive distributor of motor fuel to all sites operated by LGO for a period of 15 years. The Partnership has the right to impose the brand of fuel that is distributed to LGO. There are no minimum volume requirements that LGO is required to satisfy. The Partnership charges LGO the “dealer tank wagon” prices for each grade of product in effect at the time title to the product passes to LGO. Revenues and cost of revenues from fuel sales to LGO are separately classified in the statements of operations.
	See Note 20 for information regarding the October 2014 amendment of the PMPA Franchise Agreement.
	Revenues from Fuel Sales to Related Parties
	In addition, the Partnership distributes motor fuel and leases property to a related party of the Chief Executive Officer of the General Partner. Total revenues amounted to $24.7 million and $27.1 million for the three months ended September 30, 2014 and 2013 and $75.6 million and $78.4 million for the nine months ended September 30, 2014 and 2013, respectively. Accounts receivable amounted to $1.6 million and $1.1 million as of September 30, 2014 and December 31, 2013, respectively.
	Operating Leases of Gasoline Stations as Lessor
	The Partnership leases certain motor fuel stations to LGO under operating leases. See Note 10 for additional details. Rent income under these agreements is separately classified in the statements of operations.
	Operating Leases of Gasoline Stations as Lessee
	The Partnership leases certain motor fuel stations from related parties under operating leases cancelable by the Partnership. Rent expense under these agreements was $0.3 million for the three months ended September 30, 2014 and 2013 and $0.9 million for the nine months ended September 30, 2014 and 2013.
	Management Fees
	In connection with the acquisitions of PMI and Atlas discussed previously, the Partnership amended its Omnibus Agreement with regards to the management fee payable by the Partnership to DMI effective July 1, 2014. The revised management fee consists of a base monthly fee of $670,000 per month and a variable fee of between zero and $0.003 per gallon for wholesale fuel distribution and $0.015 per gallon for retail fuel distribution at sites operated by the Partnership. DMI may waive all or any portion of the management fee to the extent that all or a portion of the management services are either purchased from another party or not required.
	The Partnership incurred $2.7 million and $1.7 million for the three months ended September 30, 2014 and 2013 and $6.1 million and $5.0 million for the nine months ended September 30, 2014 and 2013, respectively, in management fees under the Omnibus Agreement which was classified as selling, general and administrative expenses in the statements of operations.
	Effective July 1, 2014, the Partnership entered into a sublease with DMI whereby the Partnership is responsible for paying 54.0% of the required rent payments under the DMI lease as rent for its corporate offices. The term of the sublease is 15 years. Annual rent payments under this lease are $0.3 million. Since the management fee paid by the Partnership to DMI pursuant to the Omnibus Agreement incorporates rent for office space, no incremental expense will be incurred by the Partnership.
	See Note 20 for information regarding the October 2014 amendment and restatement of the Omnibus Agreement.
	Commencing with the PMI acquisition, the Partnership incurred management fees with an affiliate for payroll and related benefits of $5.8 million and $8.7 million for the three and nine months ended September 30, 2014, respectively, which was classified as operating expenses and selling, general and administrative expenses in the statement of operations.
	As discussed in Note 3, the Partnership caused PMI to divest the Lubricants Business to Zimri. There is a transition services agreement under which PMI provides services to Zimri. PMI charged Zimri $0.2 million and $0.5 million for such services for the three and nine months ended September 30, 2014, respectively, classified as a reduction of selling, general and administrative expenses in the statement of operations. As part of the transition services agreement, the Partnership advanced $4.5 million to Zimri for working capital purposes, of which $3.0 million was repaid in the third quarter of 2014.
	Maintenance and Environmental Costs
	Certain maintenance and environmental monitoring and remediation activities are undertaken by a related party of the Partnership as approved by the former conflicts committee of the board of directors of the General Partner. The Partnership incurred $0.4 million and $0.9 million with this related party for the three and nine months ended September 30, 2014, respectively.
	Aircraft Usage
	The Partnership uses aircraft owned by a group of individuals that includes the CEO and certain other members of the board of directors of the General Partner as approved by the disinterested members of the former conflicts committee of the board of directors of the General Partner. The Partnership incurred $0.1 million and $0.2 million for the use of these aircraft for the three and nine months ended September 30, 2014, respectively.

	19. Segment Reporting
	Effective September 1, 2013, the Partnership engages in both the wholesale and retail distribution of motor fuels, primarily gasoline and diesel fuel. Effective with the PMI Transaction, the Partnership now also engages in the operation of convenience stores and branded quick-service restaurants. Given these changes, the Partnership is deemed to conduct its business in two segments: 1) the wholesale segment and 2) the retail segment. The Partnership’s measure of segment profit or loss is net income. Unallocated costs consist primarily of interest expense associated with the Credit Facility, selling, general and administrative expenses, income taxes and the elimination of the retail segment’s intersegment cost of revenues from fuel sales against the wholesale segment’s intersegment revenues from fuel sales. The profit in ending inventory generated by the intersegment fuel sale is also eliminated. Total assets by segment are not presented as the chief operating decision maker does not currently assess performance or allocate resources based on that data. Financial data for each segment is as follows (in thousands):

	20. Subsequent Events
	On October 1, 2014, the Partnership and CST announced the consummation of the previously announced sale to CST of the Partnership’s General Partner from DMI, an entity wholly owned by the Topper Trust for which Joseph V. Topper, Jr. is the trustee, and all of the membership interests in limited liability companies formed by trusts for which each of Mr. Topper and John B. Reilly, III serves as trustee, which limited liability companies own all of the IDRs. CST is one of the largest independent retailers of motor fuels and convenience merchandise in North America.
	The General Partner manages the operations and activities of the Partnership. The Partnership is managed and operated by the board of directors and executive officers of the General Partner. As a result of the consummation of the General Partner Acquisition, CST controls the General Partner and has the right to appoint all members of the board of directors of the General Partner.
	Immediately following the consummation of the General Partner Acquisition, the Partnership changed its name to “CrossAmerica Partners LP” and began trading on the New York Stock Exchange under the symbol CAPL. The following events took place in connection with the consummation of the General Partner Acquisition:
	Amended and Restated Omnibus Agreement
	The Partnership entered into an Amended and Restated Omnibus Agreement, dated as of October 1, 2014, by and among the Partnership, the General Partner, DMI, CST Services LLC, an affiliate of CST (the “Company”), LGO and Mr. Topper (the “Amended Omnibus Agreement”), which amends and restates the Original Omnibus Agreement. The terms of the Amended Omnibus Agreement were approved by the former conflicts committee of the board of directors of the General Partner, which is comprised solely of independent directors.
	General. Pursuant to the Amended Omnibus Agreement, the Company agrees, among other things, to provide, or cause to be provided, to the Partnership the management services previously provided by DMI on substantially the same terms and conditions as were applicable to DMI under the Original Omnibus Agreement. Pursuant to the terms of a transition services agreement by and between DMI and the Company, DMI will continue to provide the management services it provided under the Original Omnibus Agreement to the Partnership on behalf of the Company until December 31, 2014.
	The initial term of the Amended Omnibus Agreement is five years and will automatically renew for additional one year terms unless any party provides written notice to the other parties 180 days prior to the end of the then current term. The Partnership has the right to terminate the agreement at any time upon 180 days’ prior written notice.
	Rights of First Refusal. The Amended Omnibus Agreement provides that Mr. Topper, DMI and LGO agree, and are required to cause their controlled affiliates to agree, that for so long as Mr. Topper is an officer or director of the General Partner or CST, if (a) Mr. Topper, DMI, LGO, or any of their controlled affiliates have the opportunity to acquire assets used, or a controlling interest in any business primarily engaged, in the wholesale motor fuel distribution or retail gas station operation businesses, and (b) the assets or businesses proposed to be acquired have a value exceeding $5.0 million in the aggregate, then Mr. Topper, DMI, LGO, or their controlled affiliates will offer such acquisition opportunity to the Partnership and give the Partnership a reasonable opportunity to acquire, at the same price plus any related transaction costs and expenses, such assets or business, either before or promptly after the consummation of such acquisition by Mr. Topper, DMI, LGO, or their controlled affiliates. The decision to acquire or not acquire any such assets or businesses requires the approval of the conflicts committee of the board of directors of the General Partner. Any assets or businesses that the Partnership does not acquire pursuant to the right of first refusal may be acquired and operated by Mr. Topper, DMI, LGO, or their controlled affiliates.
	Rights of First Offer. The Amended Omnibus Agreement provides that Mr. Topper, DMI and LGO agree, and are required to cause their controlled affiliates to agree, for so long as Mr. Topper is an officer or director of the General Partner or CST, to notify the Partnership of their desire to sell any of their assets or businesses if (a) Mr. Topper, DMI, LGO, or any of their controlled affiliates, decides to attempt to sell (other than to another controlled affiliate of Mr. Topper, DMI or LGO) any assets used, or any interest in any business primarily engaged, in the wholesale motor fuel distribution or retail gas station operation businesses, to a third party and (b) the assets or businesses proposed to be sold have a value exceeding $5.0 million in the aggregate. Prior to selling such assets or businesses to a third party, Mr. Topper, DMI and LGO are required to negotiate with the Partnership exclusively and in good faith for a reasonable period of time in order to give the Partnership an opportunity to enter into definitive documentation for the purchase and sale of such assets or businesses on terms that are mutually acceptable to Mr. Topper, DMI, LGO, or their controlled affiliates, and the Partnership. If the Partnership and Mr. Topper, DMI, LGO, or their controlled affiliates have not entered into a letter of intent or a definitive purchase and sale agreement with respect to such assets or businesses within such period, Mr. Topper, DMI, LGO, and their controlled affiliates, have the right to sell such assets or businesses to a third party following the expiration of such period on any terms that are acceptable to Mr. Topper, DMI, LGO, or their controlled affiliates, and such third party. The decision to acquire or not to acquire assets or businesses pursuant to this right requires the approval of the conflicts committee of the board of directors of the General Partner.
	Amendment to Wholesale Fuel Supply Agreement with LGO
	A subsidiary of the Partnership entered into an Amendment to the PMPA Franchise Agreement, effective as of October 1, 2014, by and between LGW, a subsidiary of the Partnership, and LGO (the “Wholesale Fuel Supply Agreement Amendment”) pursuant to which the pricing terms were amended. Prior to the Wholesale Fuel Supply Agreement Amendment, the agreement provided that the Partnership charge LGO dealer tank wagon pricing, which provided for a variable cent-per-gallon margin for each grade of product in effect at the time title to the product passed to LGO. The Wholesale Fuel Supply Agreement Amendment amends the pricing terms of the agreement to provide for rack plus pricing and was approved by the former conflicts committee of the board of directors of the General Partner. This pricing change is not expected to have a material impact on net income over the remaining term of the agreement.
	Voting Agreement
	Mr. Topper entered into a Voting Agreement dated as of October 1, 2014, by and among Mr. Topper, the Topper Trust, DMI, an entity wholly owned by the Topper Trust for which Mr. Topper is the trustee (collectively, the “Topper Sellers”) and CST (the “Voting Agreement”) pursuant to which each of the Topper Sellers agrees that at any meeting of the holders of shares of CST common stock or common units or subordinated units of the Partnership it will vote or cause to be voted such Topper Seller’s shares or units, respectively, in accordance with the recommendation of the board of directors of CST or the board of directors of the General Partner, respectively. The Voting Agreement will remain in effect with respect to any Topper Seller for so long as any such Topper Seller is (a) a director or officer of CST or affiliate thereof, including the Partnership, (b) the beneficial owner of more than 3% of the outstanding common stock of CST or (c) the beneficial owner of 10% or more of the outstanding common units or subordinated units of the Partnership.
	Board of Directors
	On and effective as of October 1, 2014, Melinda B. German, Warren S. Kimber, Jr., John F. Malloy, Maura E. Topper and Robert L. Wiss, each a member of the board of directors of the General Partner, resigned in his or her capacity as such. Mr. Topper and Mr. Reilly remain members of the board of directors of the General Partner. CST has agreed to cause the appointment of Mr. Topper as a director of the General Partner for a period of at least five years commencing on October 1, 2014 or until a change in control of CST including circumstances in which CST no longer controls the General Partner. Further, Mr. Topper may be removed from the board of directors of the General Partner in certain circumstances where cause exists.
	On and effective as of October 1, 2014, CST as the owner of the General Partner appointed each of the following as members to the board of directors of the General Partner: Kimberly S. Lubel, Chief Executive Officer, President and Chairman of the board of directors of CST, Clayton E. Killinger, Senior Vice President and Chief Financial Officer of CST, and Stephan F. Motz, Senior Vice President and Chief Development Officer of CST, as directors of the board of directors of the General Partner, and Gene Edwards and Justin A. Gannon as independent directors of the board of directors of the General Partner.
	Employment Agreement
	Mr. Topper and the Company entered into an employment agreement dated as of October 1, 2014 (the “Topper Employment Agreement”), pursuant to which Mr. Topper was appointed as the Chief Executive Officer and President of the General Partner. The Topper Employment Agreement has a term of one year and will automatically renew for an additional one year term unless the parties agree otherwise or either party gives 60-day written notice prior to the end of the initial term. Mr. Topper’s base salary is $525,000 per year. He is eligible to receive a short-term incentive award equal to 75% of his base salary and an equity award equal to 200% of his base salary. Mr. Topper is entitled to participate in all employee benefit plans and programs generally available to similarly situated executives of the Company. The Company may terminate Mr. Topper’s employment at any time for any reason.
	Per the terms of the Topper Employment Agreement, Mr. Topper agrees that, during his employment and for a period equal to the greater of (i) the balance of his employment term and (ii) one year following termination for cause or his resignation without good reason (the “Restricted Period”), (x) he will not solicit or in any way be involved with any prior, current or prospective customer, client, consultant, broker or business partner of, or any person who had dealings with, the Company or the Partnership and (y) he will not solicit for employment any person who is or was within the preceding six months an employee or consultant of the Company or the Partnership. Per the terms of the Topper Employment Agreement, during the Restricted Period, Mr. Topper also agrees that he will not associate in any way with any business that at any time during the Restricted Period is engaged in the business of the Company or the Partnership other than those activities and businesses that Mr. Topper controls as of October 1, 2014.
	Because effective as of October 1, 2014, Mr. Topper is an employee of CST and no longer an employee of DMI, the disinterested members of the former board of directors of the General Partner authorized a grant of 5,670 profits interests pursuant to the Lehigh Gas Partners LP 2012 Incentive Award Plan to Mr. Topper, based on compensation earned by Mr. Topper for services rendered from January 1, 2014 through September 30, 2014. The profits interests are to vest on November 10, 2014, entitle the recipient to receive cash distributions proportionate to those received by common unitholders of the Partnership and represent Class B Units in LGP Operations LLC, a wholly owned subsidiary of the Partnership.
	Sale of Wholesale Fuel Supply Contracts and Assignment of Leases to DMI
	The Partnership, DMI and LGO consummated a series of transactions pursuant to which DMI acquired, for an aggregate purchase price of $5.7 million and an earn-out in the amount of $0.8 million if DMI renews a certain customer contract, the wholesale fuel supply rights for 78 locations in Pennsylvania and New York previously supplied by the Partnership and the fuel supply rights of the Partnership to such sites was terminated. In addition, subleases for 12 of the sites, previously leased to the Partnership, were assigned to DMI or its affiliates. The terms of the transaction were approved by the former conflicts committee of the board of directors of the General Partner, which was comprised solely of independent directors. The volume associated with these sites for 2013 was approximately 94 million gallons, of which approximately 36 million gallons represents sales to a sub-wholesaler at a de minimus margin and approximately 28 million gallons relates to a contract with a single customer for which the contract expires in 2015. In addition, rent expense for the leasehold sites included in the transaction exceeded the rent income on an annual basis by approximately $0.6 million for 2013.
	Because this was a transaction between entities under common control, the Partnership derecognized the assets and liabilities associated with the wholesale fuel supply contracts and leases and recognized the approximate $2.1 million excess of the purchase price over the net book value of the net assets divested as a contribution to partners’ capital on October 1, 2014.
	Accelerated Vesting
	In connection with the change in control of the General Partner upon the closing of the General Partner Acquisition as specified in the Lehigh Gas Partners LP Executive Income Continuity Plan, all unvested awards held by covered persons vested on October 1, 2014. As a result, 167,535 phantom units and 9,622 profits interests granted to employees of DMI vested. Upon the vesting of the phantom units, 101,456 common units were issued, net of units withheld for income taxes.
	In addition, 2,045 phantom units and 15,429 profits interests granted to members of the board of directors vested on October 1, 2014. Upon the vesting of the phantom units, 2,045 common units were issued.
	The incremental charge recorded in the fourth quarter of 2014 associated with the accelerated vesting of all these grants was approximately $4.6 million.
	Grant of Phantom Units
	On October 1, 2014, the Partnership issued 97,043 phantom units to employees of DMI. These units vest in one-third increments annually starting March 15, 2015. In addition, all unvested outstanding awards to certain employees of DMI were modified such that if within two years of a change in control, the employee is terminated involuntarily or the employee terminates his or her service due to a material reduction in base salary or a requirement to relocate his or her primary place of employment more than a specified distance from his or her current principal place of residence, then the awards will vest immediately and the employee will be paid as specified in the agreements.
	In addition, in October 2014, the board of directors approved that on November 10, 2014, phantom units with a fair market value of $70,000 will be granted to the non-employee members of the board of directors as a part of director compensation. Such grants will vest November 10, 2015.
	Nice N Easy Acquisition
	CST had previously entered into an agreement to purchase, effective November 1, 2014 (the “Closing Date”), the convenience store assets, franchisor rights, and associated trademarks of Nice N Easy Grocery Shoppes, located in central New York with a concentration in the Syracuse, NY region. Effective on the Closing Date, CST assigned the real property, including underground storage tanks and canopies, to LGWS and the related fuel distribution agreements to LGW, for aggregate cash consideration of $65.0 million (the “Purchase Price”). In addition, LGWS entered into a lease with a subsidiary of CST for the acquired real estate and LGW entered into a wholesale fuel distribution agreement with a subsidiary of CST. CST operates the sites and purchased the working capital of the acquired assets.
	The conflicts committee of the board of directors approved the Purchase Price, subject to adjustments in the allocation of the purchase price between CST and the Partnership, to be settled no later than December 31, 2014, and the terms of the associated lease and wholesale fuel supply agreements.
	The Partnership funded the Purchase Price with borrowings under its credit facility.

Accounting Policies [Abstract]	'
Interim Financial Statements	'
	Interim Financial Statements
	The accompanying interim condensed consolidated financial statements and related disclosures are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) on the same basis as the corresponding audited financial statements for the year ended December 31, 2013, and in the opinion of management, include all adjustments of a normal recurring nature considered necessary to present fairly the Partnership’s financial position as of September 30, 2014, and the results of its operations and cash flows for the periods presented. Operating results for the three and nine months ended September 30, 2014, are not necessarily indicative of the results that may be expected for the year ending December 31, 2014, or any other future periods. The balance sheet as of December 31, 2013, was derived from the consolidated financial statements for the year ended December 31, 2013. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted under the Securities and Exchange Commission’s (“SEC”) rules and regulations for interim financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the corresponding audited consolidated financial statements and accompanying notes for the year ended December 31, 2013, included in the Partnership’s Annual Report on Form 10-K, filed with the SEC.
Reclassifications	'
	Reclassifications
	Certain reclassifications were made to prior period amounts to conform to the current year presentation. These reclassifications had no impact on net income or equity for any periods.
Revenue Recognition	'
	Revenue Recognition
	Revenues from wholesale fuel sales are recognized when fuel is delivered to the customer. Revenues from retail fuel sales are recognized when fuel is sold to the customer. Substantially all revenues from fuel sales are from sales of gasoline, with the remainder comprised of diesel and other products.
	Revenues from leasing arrangements in which the Partnership is the lessor are recognized ratably over the term of the underlying lease.
	Retail food and merchandise sales are recognized net of applicable provisions for discounts and allowances upon delivery, generally at the point of sale.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which clarifies the principles for recognizing revenue and develops a common revenue standard under U.S. GAAP and International Financial Reporting Standards. Specifically, the core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services.
	This guidance is effective January 1, 2017, and provides for modified retrospective transition. Management is currently evaluating the impact of adopting this guidance.
Inventory	'
	Inventory
	Motor fuel inventory consists of gasoline, diesel fuel and other petroleum products and is stated at the lower of average cost or market using the first-in, first-out method. No provision for potentially obsolete or slow-moving inventory has been made. The Partnership records inventory from the time of the purchase of motor fuels from third party suppliers until the retail sale to the end customer.
	Food and merchandise inventory is valued at the lower of cost or market using the first-in, first-out method.
Asset Retirement Obligations	'
	Asset Retirement Obligations
	The Partnership is obligated by contractual or regulatory requirements or contingently obligated at the discretion of the lessor to remove certain equipment, such as underground gasoline storage tanks, or perform other remediation upon retirement of certain assets at sites at which the Partnership is the lessee. Certain states statutorily require removal of the underground storage tanks at a certain point in time. An asset retirement obligation is recognized in the period incurred, which is generally either at the time of lease inception or at the time a decision is made to close a site. Determination of the amounts recognized is based on numerous estimates and assumptions, including expected settlement dates and probability of occurrence, future retirement costs, future inflation rates and credit-adjusted risk-free rates. The Partnership’s asset retirement obligations, which are primarily included in other long-term liabilities in the balance sheets, totaled $2.0 million and $2.2 million at September 30, 2014 and December 31, 2013, respectively.
Asset Impairment	'
	Asset Impairment
	The Partnership reviews long-lived assets, including property and equipment and intangible assets other than goodwill, for impairment when events or changes in circumstances indicate the carrying amount of the long-lived asset (group) might not be recoverable in accordance with ASC 360, “Impairment or Disposal of Long-Lived Assets.” Such events and circumstances include, among other factors: operating losses; market value declines; changes in the expected physical life of an asset; changes in business plans or those of major customers, suppliers or other business partners; changes in competition and competitive practices; uncertainties associated with the U.S. and world economies; changes in the expected level of capital, operating or environmental remediation expenditures; and changes in governmental regulations or actions. The impairment evaluation is initially based on the projected undiscounted cash flows of the asset (group), including residual value upon eventual disposition. If the projected undiscounted cash flows of the asset (group) are less than its carrying value, the impairment loss is measured by comparing the present value of the future cash flows associated with the asset (group) to its carrying value and is recorded at that time.
New Accounting Guidance	'
	New Accounting Guidance
	Discontinued Operations
	In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of an Entity, which revises the criteria to qualify as a discontinued operation and requires new disclosures. Under this guidance, a discontinued operation is (1) a component of an entity or group of components that has been disposed of or classified as held for sale that represents a strategic shift that has or will have a major effect on an entity’s operations and financial results or (2) an acquired business that is classified as held for sale on the date of acquisition. This guidance also permits companies to have continuing cash flows and significant continuing involvement with the disposed component.
	The Partnership disposes of individual sites or groups of sites from time to time that generally do not represent a strategic shift and generally do not have a major effect on operations or financial results. As a result of this new guidance, these disposals will generally not meet the criteria for recognition as a discontinued operation. The Partnership has early adopted this guidance on a prospective basis effective January 1, 2014.

'Rights of First Refusal. The Amended Omnibus Agreement provides that Mr. Topper, DMI and LGO agree, and are required to cause their controlled affiliates to agree, that for so long as Mr. Topper is an officer or director of the General Partner or CST, if (a) Mr. Topper, DMI, LGO, or any of their controlled affiliates have the opportunity to acquire assets used, or a controlling interest in any business primarily engaged, in the wholesale motor fuel distribution or retail gas station operation businesses, and (b) the assets or businesses proposed to be acquired have a value exceeding $5.0 million in the aggregate, then Mr. Topper, DMI, LGO, or their controlled affiliates will offer such acquisition opportunity to the Partnership and give the Partnership a reasonable opportunity to acquire, at the same price plus any related transaction costs and expenses, such assets or business, either before or promptly after the consummation of such acquisition by Mr. Topper, DMI, LGO, or their controlled affiliates.

'Rights of First Offer. The Amended Omnibus Agreement provides that Mr. Topper, DMI and LGO agree, and are required to cause their controlled affiliates to agree, for so long as Mr. Topper is an officer or director of the General Partner or CST, to notify the Partnership of their desire to sell any of their assets or businesses if (a) Mr. Topper, DMI, LGO, or any of their controlled affiliates, decides to attempt to sell (other than to another controlled affiliate of Mr. Topper, DMI or LGO) any assets used, or any interest in any business primarily engaged, in the wholesale motor fuel distribution or retail gas station operation businesses, to a third party and (b) the assets or businesses proposed to be sold have a value exceeding $5.0 million in the aggregate. Prior to selling such assets or businesses to a third party, Mr. Topper, DMI and LGO are required to negotiate with the Partnership exclusively and in good faith for a reasonable period of time in order to give the Partnership an opportunity to enter into definitive documentation for the purchase and sale of such assets or businesses on terms that are mutually acceptable to Mr. Topper, DMI, LGO, or their controlled affiliates, and the Partnership. If the Partnership and Mr. Topper, DMI, LGO, or their controlled affiliates have not entered into a letter of intent or a definitive purchase and sale agreement with respect to such assets or businesses within such period, Mr. Topper, DMI, LGO, and their controlled affiliates, have the right to sell such assets or businesses to a third party following the expiration of such period on any terms that are acceptable to Mr. Topper, DMI, LGO, or their controlled affiliates, and such third party.

'These units vest in one-third increments annually starting March 15, 2015. In addition, all unvested outstanding awards to certain employees of DMI were modified such that if within two years of a change in control, the employee is terminated involuntarily or the employee terminates his or her service due to a material reduction in base salary or a requirement to relocate his or her primary place of employment more than a specified distance from his or her current principal place of residence, then the awards will vest immediately and the employee will be paid as specified in the agreements.
