Accounting Policies [Abstract]
Basis of Presentation	2. Basis of Presentation The unaudited consolidated condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X for interim financial information. Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) for interim financial reporting. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The consolidated balance sheet at December 31, 2015 has been derived from audited financial statements but does not include all of the information and notes required by GAAP for complete financial statements. Certain reclassifications were made to the financial statements for the prior period to conform to current period presentation. The interim financial information contained herein should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2015 included in the Company’s Annual Report on Form 10-K, as filed with the SEC on February 23, 2016. Operating results for the quarter and nine months ended September 30, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016 or for any future interim periods. The preparation of unaudited consolidated condensed financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure related thereto at the date of the unaudited consolidated condensed financial statements and the reported amounts of revenues and expenses during the reporting period. Management evaluates these estimates and assumptions on an ongoing basis. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited interim consolidated condensed financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from estimates.

The effect of potentially dilutive shares for the nine months ended September 30, 2016 is calculated assuming that (i) the restricted stock unit grants totaling 10,755 provided to the independent directors on May 18, 2016, which will vest during the second quarter of 2017, and the 8,660 restricted stock units provided to the independent directors on June 18, 2015, which vested during the second quarter of 2016, had been fully converted to shares on those grant dates and (ii) the $67.8 million of the performance fee for the quarter ended June 30, 2015, which was reinvested in shares by the Manager on August 1, 2016, had been reinvested in shares by the Manager in July 2015. The convertible senior notes that were issued on July 15, 2014 were anti-dilutive for the nine months ended September 30, 2016.

For the nine months ended September 30, 2015, the effect of potentially dilutive shares reflected for the quarter ended September 30, 2015 above and the 12,525 restricted stock unit grants provided to the independent directors on May 21, 2014, which vested during the second quarter of 2015, were anti-dilutive due to the Company’s net loss for the nine months ended September 30, 2015. In addition, the convertible senior notes that were issued on July 15, 2014 were anti-dilutive for the quarter and nine months ended September 30, 2015.

(2) The weighted average remaining life of the deferred financing costs at September 30, 2016 was 5.7 years. The total undrawn capacity on the revolving credit facilities at IMTT, Atlantic Aviation, CP&E, MIC Hawaii and MIC Corporate was $1.1 billion and $1.4 billion at September 30, 2016 and October 31, 2016, respectively. MIC Corporate During the nine months ended September 30, 2016, the Company drew down $196.0 million and repaid $132.0 million on its senior secured revolving credit facility primarily for general corporate purposes. At September 30, 2016, the outstanding balance was $80.0 million and the undrawn portion was $330.0 million. In October 2016, the Company repaid the outstanding balance in full. On July 15, 2016, the Company adjusted the conversion rate related to its five-year, $350.0 million aggregate principal amount of 2.875% convertible senior notes. The conversion rate increased to 12.0091 shares of common stock per $1,000 principal amount. The adjustment reflects the impact of dividends paid by the Company from July 15, 2015, the last anniversary date of the convertible senior notes. On October 13, 2016, the Company completed an underwritten public offering of $350.0 million aggregate principal amount of 2.0% convertible senior notes due 2023. On October 28, 2016, the underwriters exercised in full, their option to issue an additional $52.5 million in convertible senior notes. The net proceeds of $392.4 million were partially used to repay a portion of the drawn balance under the revolving credit facility under the New AA Credit Agreement (see below), the full repayment of the outstanding balances on both the MIC senior secured and IMTT revolving credit facilities and the remaining proceeds used for general corporate purposes. The notes are convertible, at the holder’s option, only upon satisfaction of one or more conditions set forth in the indenture governing the notes. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of Company common stock or a combination thereof, at the Company’s election. The initial conversion rate is 8.9364 shares per $1,000 principal amount (equivalent to an initial conversion price of approximately $111.90 per share, subject to adjustment). Upon a conversion in connection with the occurrence of certain events that constitute a “make-whole fundamental change,” the conversion rate will be increased by a specified amount with respect to notes tendered for conversion during a specified period after the effective date of the transaction. In addition, holders may require the Company to repurchase all or a portion of their notes upon a fundamental change (as defined in the indenture) at a cash repurchase price equal to 100% plus accrued and unpaid interest. The notes are not redeemable prior to maturity on October 1, 2023. The notes are the Company’s unsecured obligations and rank equal in right of payment with all of the Company’s existing and future senior unsecured indebtedness. Atlantic Aviation At September 30, 2016, Atlantic Aviation FBO Inc. (AA FBO) had a $595.9 million term loan outstanding and a $70.0 million revolving credit facility that was undrawn. The business also had $1.7 million outstanding under a stand-alone debt facility used to fund construction at a certain fixed based operation. On October 7, 2016, AA FBO completed the refinancing of its existing $595.9 million term loan and $70.0 million revolving credit facility. AA FBO entered into a new five-year first lien senior secured $400.0 million term loan facility and a new five year first lien senior secured $350.0 million revolving credit facility (the New AA Credit Agreement). The New AA Credit Agreement is guaranteed jointly and severally on a senior secured basis by Atlantic Aviation FBO Holdings LLC (Holdings) and certain subsidiaries of AA FBO. Proceeds from the new term loan facility, together with $200.0 million drawn on the revolving credit facility, were used primarily to fully repay the outstanding balance on the existing term loan facility. Subsequently, $175.0 million of the outstanding balance on the revolving credit facility was repaid and the balance at October 31, 2016 was $25.0 million, with $325.0 million of undrawn capacity. The key terms of the new term loan and revolving credit facilities are summarized in the table below. Facility Terms Term Loan Facility Revolving Credit Facility Facilities $400.0 million senior secured first lien term loan $350.0 million senior secured first lien revolving credit facility Maturity October 7, 2021 October 7, 2021 Amortization • 2.5% of the initial principal balance per annum for the first year; Revolving, payable at maturity • 5.0% of the initial principal balance per annum for the next two years; and • 7.5% of the initial principal balance per annum until maturity.

At September 30, 2016, the undrawn portion on the IMTT USD revolving credit facility and CAD revolving credit facility was $530.0 million and $50.0 million, respectively. In October 2016, IMTT repaid the outstanding $20.0 million drawn on its USD revolving credit facility. MIC Hawaii On February 10, 2016, Hawaii Gas completed the refinancing of its existing $80.0 million term loan and $60.0 million revolving credit facility. The new, five-year facilities include a reduction in interest rates on the term loan and revolving credit facility of 0.50% and 0.25%, respectively, compared with the prior facilities. The $80.0 million term loan bears interest at a variable rate of LIBOR plus an applicable margin between 1.0% and 1.75% and initially set at 1.75%. The variable rate component of the debt is fixed at 0.99% at September 30, 2016 using an interest rate swap contract through February 2020. The revolving credit facility bears interest at a variable rate of LIBOR plus an applicable margin between 1.0% and 1.75% and initially set at 1.25% and will remain unhedged. In July 2016, the solar power facilities in Hawaii entered into a ten year, $18.0 million term loan facility. The interest rate on this term loan facility floats at LIBOR plus 2.0%. This interest was fixed at 3.38% at September 30, 2016 using an interest rate swap contract through June 30, 2026. On August 31, 2016, the Company acquired a design-build mechanical contractor business and assumed $3.4 million in long-term debt.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	7. Derivative Instruments and Hedging Activities Interest Rate Contracts The Company and certain of its businesses have in place variable-rate debt. Management believes that it is prudent to limit the variability of a portion of the businesses’ interest payments. To meet this objective, the Company enters into interest rate swap agreements to manage fluctuations in cash flows resulting from interest rate risk on a portion of its debt with a variable-rate component. These swaps change the variable-rate cash flow exposure on the debt obligations to fixed cash flows. Under the terms of the interest rate swaps, the Company receives variable interest rate payments and makes fixed interest rate payments, thereby creating the equivalent of fixed-rate debt for the portion of the debt that is swapped. At September 30, 2016, the Company had $2.9 billion of current and long-term debt, of which $1.6 billion was economically hedged with interest rate contracts, $1.2 billion was fixed rate debt and $100.0 million was unhedged. The Company does not use hedge accounting. All movements in the fair value of the interest rate swaps are recorded directly through earnings. As discussed in Note 6, “Long-Term Debt”, Atlantic Aviation entered into five-year senior secured $400.0 million term loan facility. The interest rate on the term loan facility floats at LIBOR plus an applicable margin between 1.50% and 2.25%. On October 21, 2016, the business entered into $400.0 million of interest rate caps with a strike price of 1.0% to hedge the one month LIBOR floating rate interest exposure on the new Atlantic Aviation term loan facility. The business paid $8.6 million in upfront premiums to enter into the caps. As part of the refinancing, Atlantic Aviation paid $17.8 million in interest rate swap breakage fees associated with the termination of out-of-the-money interest rate swap contracts related to the prior term loan facility. As discussed in Note 6, “Long-Term Debt”, the solar power facilities in MIC Hawaii entered into a ten year, $18.0 million amortizing term loan facility in July 2016. The interest rate on this term loan facility floats at LIBOR plus 2.0%. Concurrently, it entered into an amortizing interest rate swap contract with an original notional of $18.0 million. The contract is scheduled to amortize concurrently with the term loan and fixes the interest rate at 3.38% as at September 30, 2016. In February 2016, in conjunction with the refinancing, as discussed in Note 6, “Long-Term Debt”, Hawaii Gas entered into a new interest rate swap contract for an $80.0 million notional that took effect on August 8, 2016, upon the maturity of the existing interest rate swap, and expires on February 8, 2020. This new interest rate swap fixes the interest rate on the $80.0 million term loan at 2.74% as of September 30, 2016. Commodity Price Hedges The risk associated with fluctuations in the prices Hawaii Gas, a business within the MIC Hawaii reportable segment, pays for propane is principally a result of market forces reflecting changes in supply and demand for propane and other energy commodities. Hawaii Gas’s gross profit is sensitive to changes in propane supply costs and Hawaii Gas may not always be able to pass through product cost increases fully or on a timely basis, particularly when product costs rise rapidly. In order to reduce the volatility of the business’ propane market price risk, Hawaii Gas had used and expects to continue to use over-the-counter commodity derivative instruments including price swaps. Hawaii Gas does not use commodity derivative instruments for speculative or trading purposes. Over-the-counter derivative commodity instruments used by Hawaii Gas to hedge forecasted purchases of propane are generally settled at expiration of the contract. Financial Statement Location Disclosure for Derivative Instruments The Company measures derivative instruments at fair value using the income approach which discounts the future net cash settlements expected under the derivative contracts to a present value. These valuations use primarily observable (level 2) inputs, including contractual terms, interest rates and yield curves observable at commonly quoted intervals.

Under the Plan, the Compensation Committee determines the persons who will receive awards, the time at which they are granted and the terms of the awards. Type of awards include stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalent rights, cash-based awards and other stock-based awards. At September 30, 2016, there were no awards outstanding under this Plan.

Under the terms of the equity distribution agreement, the Company may also sell shares to any sales agent as principal for its own account. The Company is under no obligation to sell shares under the ATM Program. Through September 30, 2016, the Company sold 99,100 shares of common stock pursuant to the agreement for net proceeds of $8.1 million (after commissions and fees). MIC Direct The Company maintains a dividend reinvestment/direct stock purchase program, named “MIC Direct”, that allows for the issuance of up to 1.0 million additional shares to participants in this program.

Reportable Segments

Segment Reporting [Abstract]
Reportable Segments	9. Reportable Segments At September 30, 2016, the Company’s businesses consist of four reportable segments: IMTT, Atlantic Aviation, CP&E and MIC Hawaii. IMTT IMTT provides bulk liquid storage, handling and other services in North America through ten terminals located in the United States, one terminal in Quebec, Canada and one partially owned terminal in Newfoundland, Canada. IMTT derives the majority of its revenue from storage and handling of petroleum products, various chemicals, renewable fuels, and vegetable and animal oils. Based on storage capacity, IMTT operates one of the largest third-party bulk liquid terminals businesses in the United States. Revenue from IMTT is included in service revenue. Atlantic Aviation Atlantic Aviation derives the majority of its revenues from fuel delivery services and from other airport services, including de-icing and aircraft hangar rental. All of the revenue of Atlantic Aviation is generated at airports in the U.S. At September 30, 2016, the business operates at 69 airports. Revenue from Atlantic Aviation is included in service revenue. CP&E The CP&E business segment derives revenue from solar, wind and gas-fired power facilities. Revenues from the solar, wind and gas-fired power facilities are included in product revenue. As of September 30, 2016, the Company has controlling interests in five utility-scale solar photovoltaic power facilities, two wind power facilities and 100% ownership of a gas-fired power facility that are located in the United States. The solar and wind power facilities that are operational at September 30, 2016 have an aggregate generating capacity of 260 megawatt (MW) of wholesale electricity to utilities. These facilities sell substantially all of the electricity generated, subject to agreed upon pricing formulas, to electric utilities pursuant to long-term (typically 20 – 25 years) power purchase agreements (PPAs). These projects are held in LLCs, and are treated as partnerships for income tax purposes, with co-investors. The acquisition price on these projects can vary depending on, among other things, factors such as the size of the project, PPA terms, eligibility for tax incentives, debt package, operating cost structure and development stage. A completed project takes out all of the construction risk, testing and costs associated with construction contracts. The Company has certain rights to make decisions over the management and operations of these solar and wind power facilities. The Company has determined that it is appropriate to consolidate these projects, with the co-investors’ interest reflected as “noncontrolling interests” in the consolidated condensed financial statements. On April 1, 2015, the Company acquired 100% of BEC. As a result of this transaction, the financial results of BEC have been consolidated as part of CP&E segment since the acquisition date. BEC is a 512 MW gas-fired power facility located in Bayonne, New Jersey, adjacent to IMTT’s Bayonne facility. BEC has tolling agreements with a creditworthy off-taker for 62.5% of its power generating capacity and power produced is delivered to New York City via a dedicated transmission cable under New York Harbor. The tolling agreements generate revenue whether or not the facility is in use for power production. In addition to revenue related to the tolling agreement and capacity payments from the grid operator, BEC generates an energy margin when the facility is dispatched. MIC Hawaii Effective with this quarterly report 10Q, the Company is combining its businesses and projects in Hawaii into a single segment, consistent with how the Company is managing those operations. Prior to this report, MIC Hawaii consisted solely of Hawaii Gas. MIC Hawaii now comprises: Hawaii Gas, Hawaii’s only government-franchised gas utility and an unregulated liquefied petroleum gas distribution business providing gas and related services to commercial, residential and governmental customers; a mechanical contractor focused on designing and constructing energy efficient heating, ventilation and air conditioning systems and related building infrastructure; and controlling interests in renewable and distributed power facilities including two facilities on Oahu. Revenue from Hawaii Gas and the renewable power facilities are recorded in product revenue. Revenue from the mechanical contractor business is recorded in service revenue. Revenue from Hawaii Gas is generated from the distribution and sales of synthetic natural gas (SNG), liquefied petroleum gas (LPG) and liquefied natural gas (LNG). Revenue is primarily a function of the volume of SNG, LPG and LNG consumed by customers and the price per thermal unit or gallon charged to customers. Because both SNG and LPG are derived from petroleum, revenue levels, without organic growth, will generally track global oil prices.

The Company issued 232,488 shares for the quarter ended September 30, 2016, including 77,751 shares that were issued in October 2016 for the September 2016 monthly base management fee. (2) In July 2015, the Board requested, and the Manager agreed, that $67.8 million of the performance fee for the quarter ended June 30, 2015 be settled in cash in July 2015 to minimize dilution. The remaining $67.8 million obligation was settled and reinvested in 944,046 shares by the Manager on August 1, 2016 using the June 2016 volume weighted average share price of $71.84.

Third Amended and Restated Management Services Agreement On May 21, 2015, to give effect to the Conversion, Macquarie Infrastructure Corporation entered into a Third Amended and Restated Management Services Agreement, among the Company, MIC Ohana Corporation and the Manager. Concurrently with the Conversion, the Manager was issued 100 shares of a new series of special stock of the Company in order to induce the Manager to enter into the Third Amended Agreement. The sole purpose for the issuance of shares of special stock to the Manager was to preserve the Manager’s existing right to appoint one director who served as the chairman of the board of directors of MIC pursuant to the terms of MIC’s operating agreement, which right would otherwise have been lost upon consummation of the Conversion. Following the Conversion and the issuance of special stock, the Manager’s right to elect one director who serves as chairman remains the same as was in effect prior to the Conversion. The Company did not grant any additional rights to the Manager through the special stock issuance. On May 21, 2015, the Company entered into an amended and restated registration rights agreement with the Manager to give effect to the Conversion. Other Services The Company uses the resources of the Macquarie Group with respect to a range of advisory, procurement, insurance, hedging, lending and other services. Engagements involving members of the Macquarie Group are reviewed and approved by the Audit Committee of the Company’s Board of Directors. Macquarie Group affiliates are engaged on an arm’s length basis and frequently as a member of syndicate of providers whose other members establish the terms of the interaction. Advisory Services The Macquarie Group, and wholly-owned subsidiaries within the Macquarie Group, including Macquarie Bank Limited (MBL) and Macquarie Capital (USA) Inc. (MCUSA) have provided various advisory and other services and incurred expenses in connection with the Company’s equity raising activities, acquisitions and debt structuring for the Company and its businesses. Underwriting fees are recorded in stockholders’ equity as a direct cost of equity offerings. Advisory fees and out-of-pocket expenses relating to acquisitions are expensed as incurred. Debt arranging fees are deferred and amortized over the term of the credit facility. In October 2016, the Company completed an underwritten public offering $402.5 million aggregate principal amount of convertible senior notes, including notes offered pursuant to the underwriters’ exercise of an over-allotment option. MCUSA served as an underwriter and received $403,000 from the Company for such services. On June 24, 2015, the Company commenced the ATM program where the Company may offer and sell shares of its common stock, par value $0.001 per share, from time to time having an aggregate gross offering price of up to $400.0 million. These sales, if any, will be made pursuant to the terms of an equity distribution agreement entered into between the Company and the sales agents, with MCUSA being one of the sales agents. Under the terms of the equity distribution agreement, the Company may also sell shares to any sales agent as principal for its own account at a price agreed upon at the time of the sale. For the quarter and nine months ended September 30, 2016 and 2015, the Company did not engage MCUSA for such activities. In March 2015, the Company completed an underwritten public offering of 6,109,375 shares. In this offering, MCUSA served as a joint book-running manager and an underwriter and received $2.3 million from the Company for such services.

At September 30, 2016 and December 31, 2015, the revolving credit facility remained undrawn. For the quarter and nine months ended September 30, 2016, Atlantic Aviation incurred and paid $30,000 and $88,000, respectively, in commitment fees related to MBL’s portion of the revolving credit facility, compared with $29,000 and $85,000 for the quarter and nine months ended September 30, 2015, respectively. In October 2016, the revolving credit facility was terminated in conjunction with the completion of Atlantic Aviation’s new credit facility. During 2015, the Company increased the aggregate commitments under its senior secured revolving credit facility at the holding company from $250.0 million to $410.0 million with all terms remaining the same. MIHI LLC’s commitment of $50.0 million out of the total commitment remained unchanged.

The Company also assumed interest rate swap contracts of which MBL was one of its counterparties. During the quarter and nine months ended September 30, 2015, the Company incurred and paid $3,000 and $8,000, respectively, in commitment fees to MIHI LLC for its portion of the revolving credit facility and during the quarter ended June 30, 2015, the Company paid $396,000 to MBL for interest in connection with the interest rate swap settlements. In July 2015, in connection with the repayment of the outstanding balance on BEC’s debt facilities, the Company paid $4.8 million in interest rate swap breakage fees associated with the termination of out-of-the money interest rate swap contracts to MBL. Other Transactions Macquarie, through the Macquarie Insurance Facility (MIF), has an aggregated insurance buying program. By combining the insurance premiums of Macquarie owned and managed funds, MIF has been able to deliver very competitive terms to businesses that participate in the facility. MIF earns a commission from the insurers. No payments were made to MIF by the Company during the nine months ended September 30, 2016 and 2015. During the quarter ended March 31, 2016, the Company renewed its Directors and Officers liability insurance using several of the MIF insurers. IMTT, Atlantic Aviation, CP&E and MIC Hawaii purchase and renew property and casualty insurance coverage on an ongoing basis from insurance underwriters who then pay commissions to MIF. For the nine months ended September 30, 2016 and 2015, no payments were made directly to MIF for property and casualty insurance. During 2015, Hawaii Gas appointed an independent director who is the chief executive officer of one of the lenders in the syndicate responsible for its $80.0 million term loan facility and its $60.0 million revolving credit facility, which were refinanced in February 2016. Of the $80.0 million term loan facility and the $60.0 million revolving credit facility, the portion committed by this lender changed from the original $11.4 million and $8.6 million, respectively, to $8.6 million and $6.4 million, respectively.

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of unaudited consolidated condensed financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure related thereto at the date of the unaudited consolidated condensed financial statements and the reported amounts of revenues and expenses during the reporting period. Management evaluates these estimates and assumptions on an ongoing basis. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited interim consolidated condensed financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from estimates.
