Item 5. Other Events

On March 1, 2002, Crown Castle International Corp. (the "Company") announced
that it plans to record a non-recurring restructuring charge estimated to be
between approximately $7 million to $13 million with respect to redundancies and
the disposition of certain service lines in connection with its United Kingdom
operations.  The charge is expected to be reflected in the Company's results of
operations for the first quarter 2002.  The announcement was made during the
Company's conference call relating to fourth quarter and year-end 2001 results.
An audio archive of the conference call will be available on the Company's
website at www.crowncastle.com and will be accessible for approximately 90 days.

                          FORWARD-LOOKING STATEMENTS

This document, including exhibits attached hereto contains numerous forward-
looking statements, based on management's current beliefs and assumptions. The
forward-looking statements involve expectations, projections and estimates
regarding the wireless industry or Crown Castle International Corp. (including
its subsidiaries), including expectations, projections and estimates regarding:
(i) revenues (including site rental and broadcast transmission revenue), (ii)
tower gross profit, (iii) service gross profit, (iv) general and administrative
expenses, (v) EBITDA, (vi) capital expenditures, (vii) interest expense
(including cash interest expense), and (viii) towers to be built.

Such forward-looking statements are subject to numerous risks, uncertainties and
assumptions, including (i) those relating to the matters described above, (ii)
those included in the Company's filings with the Securities and Exchange
Commission, and (iii) the following:

..  Demand for towers and wireless communication sites may be lower or slower
   than anticipated for numerous reasons, including reduced carrier expansion,
   carrier consolidation, network sharing, technology development, or RF health
   concerns

                                       1


..  Demand for wireless communications may be lower or slower than anticipated
   for numerous reasons, including slow customer adoption rates of 2.5/3G and
   other technologies

..  Our strategy may be more difficult to implement than anticipated due to
   financial or other reasons, including our significant amount of indebtedness,
   or reduced cash flow as a result of reduced revenues or increased operating
   costs, interest rates or capital expenditures

Should one or more of these risks materialize, or should any underlying
assumption prove incorrect, actual results may vary materially from those
projected in the forward-looking statements.  The Company assumes no obligation
to update publicly any forward-looking statements, whether as a result of new
information, future events or otherwise.
