Lateral Slide Bridge Project in Texas

Loop 345 - MedicalType of Job: Lateral Slide Bride
Cost: $14.6 Million
Duration: 2013-2016
Location: San Antonio, TX
Client: Texas Department of Transportation

The LP345/Medical Project (Fred/Med) executed the first lateral bridge slide in TxDOT's 97-year history. This bridge replaced the on-grade intersection of Fredericksburg Road and Medical Center, also known as the main thoroughfare into San Antonio’s Medical Center. Due to the excessive congestion at this intersection and the ambulance traffic, it was critical that this project was completed on schedule.

Per the original contract terms, TSC had just 14 days to close the intersection, remove the pavement, excavate down to grade, set the substructure, install the beams, and cast the deck. After more than a year of planning the Bridge Slide, TSC closed the intersection at 12:01 a.m. on a Friday. By the following Monday morning rush hour, the new bridge was in place. We successfully slid the 4-million-pound bridge approximately 185 feet into place flawlessly. At the time, the 185 feet of lateral movement was one of the longest lateral bridge slides performed in the United States.
