                       CROWN CASTLE INTERNATIONAL REPORTS
                     FIRST QUARTER RESULTS AND EXTENSION OF
                       CROWN CASTLE ATLANTIC JOINT VENTURE

May 5, 2003 - HOUSTON, TEXAS - Crown Castle International Corp. (NYSE:CCI) today
reported results for the first quarter ended March 31, 2003.

     Total revenue for the first quarter of 2003 was $216.7 million, compared to
$220.6 million for the first quarter of 2002. Site rental and broadcast
transmission revenue for the first quarter of 2003 increased 15.4% to $185.0
million, up from $160.3 million for the same period in 2002. Net loss (after
deduction of dividends on preferred stock and net of gains on repurchases of
preferred stock of $3.3 million for first quarter 2003) improved to $83.4
million for the first quarter of 2003 from a net loss of $123.5 million for the
same period in 2002. First quarter loss per share was $0.38 compared to a loss
per share of $0.56 in last year's first quarter. Net cash from operating
activities for the first quarter of 2003 was $5.9 million, down from $16.0
million for the same period in 2002. Capital expenditures for the first quarter
were $52.8 million, down from $73.0 million for the same period in 2002. Free
cash flow, defined as cash from operating activities less capital expenditures,
for the first quarter of 2003 was a use of cash of $46.9 million, an improvement
from a use of cash of $56.9 million for the same period in the prior year.

OPERATING RESULTS

     US site rental revenue for the first quarter of 2003 increased 5.9% to
$107.8 million, up from $101.8 million for the same period in 2002, and UK site
rental and broadcast transmission

revenue for the first quarter of 2003 increased 33.1% to $71.1 million, up from
$53.5 million for the same period in 2002. These revenue results approximate
same tower sales as a result of the fact that 97% of Crown Castle's sites on
March 31, 2003 were in operation as of January 1, 2002. On a consolidated basis,
site rental and broadcast transmission gross margin, defined as site rental and
broadcast transmission revenue less site rental and broadcast transmission cost
of operations, increased 13.6 percent to $111.6 million, up $13.4 million in the
first quarter of 2003 from the same period in 2002. For the first quarter of
2003, US capital expenditures were $5.6 million, and UK capital expenditures
were $46.2 million (including the $33.2 million payment to British Telecom as
previously announced). Reflecting Crown Castle's strategic decision to
de-emphasize non-core service revenues, network service revenue declined to
$31.8 million for the first quarter of 2003 from $60.4 million for the same
period last year.

     "Our operations exceeded our financial targets for the first quarter
through our continued efforts to grow our recurring tower and broadcast
business, reduce capital expenditures, and decrease working capital," stated W.
Benjamin Moreland, CFO of Crown Castle. "As a result, we beat our targets for
site rental and broadcast transmission revenue, net cash from operating
activities and free cash flow for the first quarter. As we demonstrated at our
Analyst Day on April 9th, we believe substantial tenant demand exists for our
towers, which we expect will continue to drive additional long-term recurring
revenue and cash flow to our existing tower portfolio. We believe organic
leasing revenue will continue to be added during 2003 consistent with our
previously announced expectations."

     During the first quarter of 2003, Crown Castle developed 34 sites, 31 of
which were developed under our agreement with British Telecom in the UK. Also
during the first quarter, Crown Castle repaid $22.9 million of senior credit
facility debt (including $15.0 million in its CCA facility and $7.9 million in
its UK facility). At March 31, 2003, Crown Castle had $851.4 million of total
liquidity, comprised of $555.2 million of cash and cash equivalents and liquid
investments, and total availability under its senior credit facilities of $296.2
million.

CHANGES TO JOINT VENTURES WITH VERIZON

     On May 2, 2003, Crown Castle reached agreement with Verizon to extend
certain termination rights relating to Verizon's interest in the Crown Castle
Atlantic Joint Venture (CCA) until July 2007 and exchange Verizon's ownership
interests in the Crown Castle GT Joint Venture (CCGT) for additional ownership
interests in CCA. Further, Crown Castle purchased from Verizon approximately 5.1
million shares of Crown Castle common stock previously held by

                                                                     Page 3 of 6

CCGT, and CCA distributed 15.6 million shares of Crown Castle common stock
previously held by CCA to Verizon. After giving effect to the agreements, Crown
Castle owns 62.8% of CCA and 100% of CCGT. The purchase of the Crown Castle
shares, along with a payment for working capital, resulted in the use of
approximately $36.7 million in cash ($31.0 million for the shares and $5.7
million for the working capital).

     "We are extremely pleased with the commitment of Verizon, our largest US
customer, to maintain its significant position in CCA for the foreseeable
future," stated John P. Kelly, CEO of Crown Castle. "By extending Verizon's
ownership in CCA until 2007, we have eliminated the near-term prospect of
Verizon's election to exit the venture, which could have resulted in a
significant near-term cash requirement on our business. Further, we are excited
about continuing our cooperative partnership with Verizon in providing tower
infrastructure."

     Additional details regarding the changes to CCA and CCGT are available in
Crown Castle's Form 8-K to be filed on May 6, 2003.

OUTLOOK

     The following statements and outlook table are based on current
expectations and assumptions and assume a US dollar to UK pound exchange rate of
1.55 dollars to 1.00 pound and a US dollar to Australian dollar exchange rate of
0.50 US dollars to 1.00 Australian dollar. The following Outlook sections
contain forward-looking statements, and actual results may differ materially.
Information regarding potential risks which could cause actual results to differ
from the forward-looking statements herein are set forth below and in the
Company's filings with the Securities and Exchange Commission.

Based in part on the results for the first quarter of 2003, Crown Castle has
adjusted certain elements of its previously provided financial guidance for
2003, which results in expected free cash flow increasing from between $(35)
million and $0 to between $20 million and $50 million for the full year 2003.
The most significant adjustment relates to the removal of the remaining $45
million payment to British Telecom from the 2003 outlook. Crown Castle believes
it will conclude negotiations with British Telecom to eliminate this final
contractual obligation for site acquisition. Crown Castle's 2003 and 2004
projected net cash provided by operating activities assumes the effect of
converting paid-in-kind interest to cash pay for the 10 5/8%, 10 3/8%, and
11 1/4% Senior Discount Notes and the 12 3/4% Senior Exchangeable Preferred
Stock.

                           Non-GAAP Financial Measures

This press release includes presentations of Free Cash Flow and Adjusted EBITDA,
which are non-GAAP financial measures. Crown Castle defines Free Cash Flow as
net cash provided by operating activities less capital expenditures (both
amounts from the Consolidated Statement of Cash Flows). Crown Castle defines
Adjusted EBITDA as operating income (loss) plus depreciation, amortization and
accretion, non-cash general and administrative compensation charges, asset
write-down charges and restructuring charges. Free Cash Flow and Adjusted EBITDA
are not intended as alternative measures of operating results or cash flow from
operations (as determined in accordance with generally accepted accounting
principles). Further, our measure of Free Cash Flow and Adjusted EBITDA may not
be comparable to similarly titled measures of other companies. Free Cash Flow is
presented as additional information because management believes it to be a
useful indicator of our ability to execute our business strategy without
reliance on additional borrowing or the use of our cash and liquid investments.
Adjusted EBITDA is presented as additional information because management
believes it to be a useful indicator of the current financial performance of our
core businesses. In addition, Adjusted EBITDA is the measure of current
financial performance generally used in our debt covenant calculations. The
tables set forth below reconcile these non-GAAP financial measures to comparable
GAAP financial measures. Our results under GAAP are set forth in the financial
statements attached on pages 7 through 9 of this press release.

Reconciliations of Non-GAAP Financial Measures to Comparable GAAP Financial
Measures

Free Cash Flow is computed as follows:

            Cautionary Language Regarding Forward-Looking Statements

This press release contains forward-looking statements and information that are
based on management's beliefs as well as assumptions made by and information
currently available to management. Such forward-looking statements include, but
are not limited to, expectations, projections and estimates regarding (i) demand
for our sites and towers, (ii) organic leasing rates, (iii) the relationship
between Verizon and Crown Castle, (iv) currency exchange rates, (v) the outcome
of negotiations with British Telecom regarding the remaining site acquisition
payment to British Telecom, (vi) revenues, (vii) net cash provided by operating
activities, (viii) sites to be acquired and constructed, (ix) capital
expenditures, and (x) free cash flow.

Although Crown Castle believes that the expectations reflected in such
forward-looking statements are reasonable, it can give no assurance that such
expectations will prove to have been correct. Such statements are subject to
certain risks, uncertainties and assumptions, including but not limited to the
success or failure of our efforts to implement our business strategy and the
following:

     .    Our substantial level of indebtedness could adversely affect our
          ability to react to changes in our business and limit our ability to
          use debt to fund future capital needs.

     .    If we are unable to service our indebtedness, our indebtedness may be
          accelerated.

     .    Our business depends on the demand for wireless communications, which
          has been and may continue to be lower and slower than anticipated.

     .    The continuation of the current economic and telecommunications
          industry slowdown could materially and adversely affect our business
          and the business of our customers.

     .    We may be unable to manage our significant growth.

     .    The loss, consolidation or financial instability of any of our limited
          number of customers could materially decrease revenues.

     .    Restrictive covenants on our debt instruments may limit our ability to
          take actions that may be in our best interests.

     .    We operate in an increasingly competitive industry and many of our
          competitors have significantly more resources than we do or have less
          debt than we do.

     .    Technology changes may significantly reduce the demand for towers and
          wireless communications sites.

     .    2.5G/3G and other technologies, including digital terrestrial
          television, may not deploy or be adopted by customers as rapidly or in
          the manner projected.

     .    Carrier consolidation or reduced carrier expansion may significantly
          reduce the demand for towers and wireless communication sites.

     .    Network sharing and other agreements among our customers may act as
          alternatives to leasing sites from us.

     .    Demand for our network services business is very volatile which causes
          our network services operating results to vary significantly for any
          particular period.

     .    We may need additional financing for strategic growth opportunities
          which may not be available.

     .    We generally lease or sublease the land under our sites and towers and
          may not be able to maintain these leases at commercially viable rates.
          The loss of any of our ground leases could result in retirement
          obligations.

     .    Laws and regulations, which could change at any time, govern our
          business and industry, and we could fail to comply with these laws and
          regulations.

     .    We could suffer from future claims if radio frequency emissions from
          equipment on our sites and towers are demonstrated to cause negative
          health effects.

     .    Our international operations expose us to changes in foreign currency
          exchange rates.

     .    We are heavily dependent on our senior management.

     .    Certain provisions of our certificate of incorporation, bylaws and
          operative agreements and domestic and international competition laws
          could make it more difficult for a third party to acquire control of
          us or for us to acquire control of a third party, even if such a
          change in control would be beneficial to our stockholders.

     .    Sales or issuances, including as dividends, of a substantial number of
          shares of our common stock could adversely affect the market price of
          our common stock.

     .    Disputes with customers and suppliers may adversely affect results.

     .    The carrying value of our sites and related goodwill may be subject to
          impairment in the future if we are unable to add sufficient additional
          tenants to the sites.

Should one or more of these risks materialize, or should underlying assumptions
prove incorrect, actual results may vary materially from those expected. More
information about potential factors, which could affect Crown Castle's financial
results, is included in Crown Castle's filings with the Securities and Exchange
Commission.
