This joint venture project with Cianbro consisted of erecting the new Galveston Causeway Railroad Bridge and constructing an 800-foot-long tunnel under Galveston Bay to carry new water lines. The bridge is a 382-foot main lift span that rises 80 feet to allow Intercoastal waterway traffic on Galveston Bay to pass under the BNSF Railroad. All bridge work, including electrical, was self-performed by joint venture forces.

Placement of the bridge was a unique challenge. The 1,580-ton main span was built at the port, placed on barges, and then floated into place. This float-out/float-in procedure had to be completed within a 72-hour marine channel shutdown, with only a 12-hour window to close the bridge from rail traffic. View a video of the bridge placement below.
