Sam Houston Tollway Ship Channel Bridge

Houston, TX.   •   $565 Million value  

Traylor is the sponsoring partner of Ship Channel Constructors LLC (SCC), a joint venture of Traylor and Zachry Construction Corporation working on the Sam Houston Tollway Ship Channel Bridge Replacement project outside of Houston, Texas. The team is building new twin landmark cable-stayed bridges across the channel while maintaining traffic on the busy water- and roadways along the alignment. The new bridges remove foundations from the waterway and will prompt the widening and deepening of the channel to make way for supertankers and mega vessels, advancing the shipping industry in Harris County.

The new southbound bridge will be constructed first, adjacent to the existing bridge to the west. The design of the uniquely shaped main span structures has prompted innovations in construction, and the team is applying lessons learned from previous cable-stayed bridge projects.

The superstructure of the main span will be composite steel girders with precast deck panels. The approach bridges are wrapping up construction with the completion of the girder setting on the south approach in February 2022. Approach construction is estimated to be complete in summer 2022.
