Exhibit 3.73

                   CERTIFICATE OF CORRECTION FILED TO CORRECT
              A CERTAIN ERROR IN THE CERTIFICATE OF INCORPORATION
                       OF TXI Riverside California, Inc.
                 FILED IN THE OFFICE OF THE SECRETARY OF STATE
                        OF DELAWARE ON DECEMBER 22, 1997

TXI Riverside California Inc., a corporation organized and existing under and by
virtue of the General corporation Law of the state of Delaware.

DOES HEREBY CERTIFY:

     1. The name of the corporation is TXI Riverside California Inc.

     2. That a Certificate of Incorporation was filed by the Secretary of State
of Delaware on December 22, 1997, and that said Certificate requires correction
as permitted by section 103 of the General Corporation Law of the State of
Delaware.

     3. The inaccuracy or defect of said Certificate to be corrected is as
follows: The name of the corporation should be TXI Riverside Inc., as the word
California was inadvertently added to the title by a clerical error. Two
corporations were being formed at the same time and one had the word California
in the title and unfortunately it was mistakenly left in the title when the
second company was formed.

     4. Article 1. of the Certificate is corrected to read as follows;

          The name of the corporation is TXI Riverside Inc.

IN WITNESS HEREOF, said TXI Riverside Inc. has caused this Certificate to be
signed by Robert C. Moore, its Vice President-Secretary this 26th day of
December, 1997.
