The following information supplements and amends the information contained in
the Schedule 13D previously filed by Cellco Partnership, a Delaware general
partnership doing business as Verizon Wireless ("VW"), and Verizon
Communications Inc. (f/k/a Bell Atlantic Corporation), a Delaware corporation
("Verizon"), relating to the beneficial ownership of the common stock, $0.01 par
value per share, of Crown Castle International Corp., a Delaware corporation
(the "Corporation"), listed on the cover pages of this amendment.

ITEM 2.  IDENTITY AND BACKGROUND

The disclosure previously contained in Item 2 is replaced with the following:

         This Statement is being filed by Bell Atlantic Mobile, Inc., a Delaware
corporation ("BAM Inc."), and Verizon. Verizon is the indirect parent
corporation of BAM Inc.

         The principal business address of BAM Inc. is 1095 Avenue of the
Americas, New York, New York 10036. Its principal business is holding a
membership interest in Crown Atlantic Holding Company LLC, a Delaware limited
liability company ("HoldCo"). BAM Inc. obtained a membership interest in HoldCo
in connection with a distribution in complete redemption of BAM Inc.'s interest
in VW. Subsequently, BAM Inc. obtained an additional membership interest in
HoldCo by transfer and assignment from another indirect, wholly-owned subsidiary
of Verizon. The directors and officers of BAM Inc. are set forth on Schedule I
hereto, which schedule lists for each such person his or her name, business
address, present principal occupation or employment and the name, principal
business and address of any corporation or other organization in which such
employment is conducted, and citizenship, and which are incorporated herein by
reference.

         Verizon is one of the world's leading providers of communications
services. Subsidiaries of Verizon are engaged in the businesses of providing
domestic wireline telecommunications services through local telephone services,
including voice and data transport, enhanced and custom calling features,
network access, directory assistance, private lines, public telephones, customer
premises equipment distribution, systems integration, billing and collections,
and Internet access services; wireless telecommunications products and services
to United States and foreign customers, including cellular mobile service;
domestic and international publishing businesses, including print directories
and Internet-based shopping guides, as well as website creation and hosting and
other electronic commerce service; and international wireline telecommunications
investments and lease financing and other businesses. The address of Verizon's
principal executive offices is 1095 Avenue of the Americas, New York, New York
10036. The directors and officers of Verizon are set forth on Schedule II
hereto, which schedule lists for each such person his or her name, business
address, present principal occupation or employment and the name, principal
business and address of any corporation or other organization in which such
employment is conducted, and citizenship, and which are incorporated herein by
reference.

         During the last five years, neither BAM Inc. nor Verizon, and to the
best knowledge of each of them, none of the persons listed in Schedules I and
II, has been convicted in a criminal proceeding or been a party to a civil
proceeding of a judicial or administrative body of competent jurisdiction and as
a result of such proceeding been or become subject to a judgment, decree or
final order enjoining future violations of, or prohibiting or mandating
activities subject to, federal or state securities laws or finding any violation
with respect to such laws.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

The following is added to the end of Item 3:

           BAM Inc. obtained a membership interest in HoldCo in connection with
a distribution in complete redemption of BAM Inc.'s interest in VW.
Subsequently, BAM Inc. obtained an additional membership interest in HoldCo by
transfer and assignment from another indirect, wholly-owned subsidiary of
Verizon. On May 1, 2003, pursuant to the terms of the Redemption Agreement (the
"Redemption Agreement") between BAM Inc. and HoldCo, HoldCo redeemed a portion
of BAM Inc.'s membership interest in HoldCo, representing a 19.155% membership
interest, in exchange for the Contributed Shares. In connection with such
redemption, BAM Inc., the Corporation, HoldCo and CCA entered into a Letter
Agreement (the "Registration Rights Letter") that, among other things, amended
certain provisions of the Formation Agreement. The Registration Rights Letter,
among other things, provided BAM Inc. with certain rights relating to the
Contributed Shares and served as BAM Inc.'s request that the Corporation file a
registration statement on Form S-3 to register for sale all of the Contributed
Shares. This discussion is qualified in its entirety by reference to (i) the
complete text of the Redemption Agreement, attached hereto as Exhibit 4, and
(ii) the complete text of the Registration Rights Letter, attached hereto as
Exhibit 5.

ITEM 4.  PURPOSE OF TRANSACTION

The disclosure previously contained in Item 4 is replaced with the following:

           VW acquired shared voting and investment power over the Contributed
Shares on March 31, 1999, when CCA contributed the Contributed Shares to HoldCo
in connection with the formation of the joint venture contemplated by the
Formation Agreement. The discussion of the manner by which BAM Inc. acquired
shared voting and investment power with CCA, and subsequently, shared voting and
investment power with Verizon, over the Contributed Shares, is incorporated into
this Item 4 from the last paragraph of Item 3.

           Except as provided below, neither BAM Inc. nor Verizon, and to the
best knowledge of each of them, none of the persons named in Schedules I and II,
currently has any plan or proposal which relate to, or might result in, any of
the events described in paragraphs (a) through (j), inclusive, of Item 4 of
Schedule 13D. Pursuant to the Registration Rights Letter, BAM Inc. has requested
that the Corporation file a registration statement on Form S-3 to register for
sale all of the Contributed Shares. Further, BAM Inc. and Verizon may, from time
to time, consider, engage in discussions regarding or consummate, in one, or a
series of, public or private sales transactions (i) the sale or other
disposition of all or a portion of the Contributed Shares, or (ii) the purchase
of additional shares of Common Stock of the Corporation.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

The disclosure previously contained in Item 5 is replaced with the following:

           BAM Inc. is the beneficial owner of 15,597,783 shares of Common Stock
of the Corporation. BAM Inc. has, together with Verizon, shared voting power
with respect to 15,597,783 shares of Common Stock, which constitutes
approximately 7.15% of the Common Stock of the Corporation outstanding on May
2, 2003 (based on the number of shares outstanding as contained in the
Corporation's most recently filed Form 10-Q), and shared dispositive power with
respect to 15,597,783 shares of Common Stock. None of the persons listed in
Schedules I and II has voting or dispositive power with respect to any shares of
Common Stock of the Corporation.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER

The following is added to the end of Item 6:

           The discussion of the Redemption Agreement and the Registration
Rights Letter is incorporated into this Item 6 from the last paragraph of Item
3.

ITEM 7.  MATERIAL TO BE FILED AS EXHIBITS

The following is added to the end of Item 7:

Exhibit 4. Redemption Agreement dated as of May 1, 2003, between Crown Atlantic
Holding Company LLC, a Delaware limited liability company, and Bell Atlantic
Mobile, Inc., a Delaware corporation.

Exhibit 5. Letter Agreement dated as of May 1, 2003, by and among Bell Atlantic
Mobile, Inc., a Delaware corporation, Crown Atlantic Holding Company LLC, a
