                          Independent Auditors' Report

To the Plan Administrator for the
   Crown Castle International Corp.
   401(k) Plan:

We have audited the accompanying statements of net assets available for Plan
benefits of the Crown Castle International Corp. 401(k) Plan as of December 31,
2002 and 2001, and the related statements of changes in net assets available for
plan benefits for the years then ended. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for plan benefits of the Plan at
December 31, 2002 and 2001, and the changes in its net assets available for plan
benefits for the years then ended, in conformity with accounting principles
generally accepted in the United States of America.

Our audits were made for the purpose of formulating an opinion on the financial
statements taken as a whole. The supplemental schedule included as Schedule 1 is
presented for purposes of additional analysis and is not a required part of the
basic financial statements but is supplementary information required by the
Department of Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974. The supplemental schedule
is the responsibility of the Plan's management. The supplemental schedule has
been subjected to the auditing procedures applied in our audits of the financial
statements and, in our opinion, is fairly stated in all material respects in
relation to the financial statements taken as a whole.

                        CROWN CASTLE INTERNATIONAL CORP.
                                  401(k) PLAN

                          Notes to Financial Statements

                           December 31, 2002 and 2001

(1)  Plan Description

     The following description of the Crown Castle International Corp. 401(k)
     Plan (the Plan) provides only general information. Participants should
     refer to the Plan Agreement for more complete information.

     (a)  General

          The Plan is a defined contribution plan available to eligible
          employees of Crown Castle International Corp. (the Company). As of
          December 31, 2002, PNC Bank, N.A. was the trustee of the Plan, and
          served as both the custodian and the recordkeeper (see Note 7). The
          Plan was established on May 1, 1999. The Plan is subject to the
          provisions of the Employee Retirement Income Security Act of 1974
          (ERISA) and is administered by a plan administrator appointed by the
          Company.

     (b)  Contributions

          For the plan year ended December 31, 2001, eligible employees
          (participants) could elect to contribute from 1% to 15% of their
          biweekly compensation as a salary reduction contribution on a
          before-tax basis. For the plan year ended December 31, 2002,
          participants may contribute any percentage that allows the participant
          to reach the section 401(k) pre-tax contribution limit of $11,000 for
          participants under age 50. Participants who are age 50 and older can
          contribute an additional $1,000 for a total of $12,000. These salary
          reduction contributions are fully vested at all times. Participants
          may also contribute amounts representing distributions from other
          qualified plans. Participants direct the investment of their
          contributions into various investment options offered by the Plan. The
          Plan offers fifteen mutual funds and Crown Castle International Corp.
          Common Stock as of December 31, 2002. The Company matches and
          contributes 100% of the first 3% of compensation that a participant
          contributes to the Plan. Additional discretionary amounts may be
          contributed at the option of the Company's board of directors.
          Contributions are subject to certain limitations.

     (c)  Participant Accounts

          Participant accounts are maintained at fair market value. Each
          participant's account is credited with the participant's contribution
          and allocations of (a) the Company's matching contribution and (b)
          Plan earnings and losses. The benefit to which a participant is
          entitled is the benefit that can be provided from the participant's
          vested account.

     (d)  Vesting

          Participants are vested immediately in their contributions plus actual
          earnings thereon. Vesting in the Company's contribution portion of
          their accounts is based on years of continuous service. A participant
          is 100% vested after three years of credited service.

     (e)  Participant Loans

          Participants are permitted to borrow from their fund accounts a
          minimum of $1,000 up to a maximum of 50% of vested balance or $50,000,
          whichever is less. The loans are secured by the balance in the
          participant's account and bear interest at a fixed rate of prime + 1%.
          All loans are

                                                                     (Continued)

                           December 31, 2002 and 2001

          subject to specific repayment terms and must be repaid within a
          five-year period. Each participant is granted one loan at a time.

     (f)  Payment of Benefits

          Participants are permitted to withdraw any portion of their vested
          account balance due to death, permanent disability, retirement,
          attainment of age 59-1/2, in the event of financial hardship or
          termination of service. The participant may elect to receive a
          lump-sum payment, subject to federal income tax withholdings, or
          rollover the vested account balance to another qualified plan. These
          withdrawals, prior to retirement, may result in certain suspensions of
          future participation in the plan.

     (g)  Forfeitures

          Company contributions and earnings thereon that have not become
          vested, and have been forfeited by the withdrawal of participants'
          savings in accordance with the applicable provisions of the Plan, are
          applied against administrative expenses of the Plan. Excess
          forfeitures are applied to reduce the Company's contributions required
          under the Plan. Amounts forfeited were $228,123 in 2002.

     (h)  Termination of Plan

          In the event of termination of the Plan, the plan administrator will

(2)  Summary of Significant Accounting Policies

     (a)  Basis of Financial Statements

          The accompanying financial statements have been prepared on the
          accrual basis. The preparation of the financial statements in
          conformity with accounting principles generally accepted in the United
          States of America requires the plan administrator to make estimates
          and assumptions that affect the amounts reported in the financial
          statements and notes thereto. Actual results could differ from those
          estimates.

     (b)  Investment Income

          Interest income from investments is recorded on an accrual basis.
          Dividend income is recorded on the ex-dividend date.

     (c)  Investments

          Investments in common stock traded on securities exchanges and
          investment companies are valued at their last reported sales price on
          the last business day of the Plan year. Investments in collective
          trust funds are valued at the net asset value of the respective funds
          on the last day of the Plan year.

          Investment transactions are accounted for on a trade-date basis.

          In accordance with the policy of stating investments at fair value,
          changes in unrealized appreciation or depreciation are reflected in
          the statements of changes in net assets available for plan benefits.

                                                                     (Continued)

(6)  Loans to Participants

     Loans are made available to all participants on a nondiscriminatory basis
     in accordance with the specific provisions set forth in the Plan. The
     amount of a loan cannot generally exceed the lesser of $50,000 or one-half
     of a participant's total vested account balance. The loans bear interest at
     rates determined by the plan administrator, generally 1% above the prime
     rate at the time the loan is made. All loans are subject to specific
     repayment plans and are secured by the participant's nonforfeitable
     interest in his/her account equivalent to the principal amount of the loan.

     Effective February 1, 2003, the Plan changed its trustee from PNC Bank,
     N.A. to The Charles Schwab Trust Company (CSTC). In addition, the
