National Heavy Civil Division Wins Houston Ship Channel Bridge Project
Posted on September 28, 2017
On Tuesday, September 26th, the Harris County Toll Road Authority (HCTRA) took the first steps toward awarding Ship Channel Constructors (SCC), a joint venture between Traylor Bros., Inc. and Zachry Construction Corporation, a contract for construction of the Sam Houston Tollway Ship Channel Bridge Replacement. The joint venture will build two new landmark cable-stayed bridges across the channel, providing four toll lanes and full shoulders in each direction, while maintaining traffic on the busy water- and roadways along the alignment. Critical to the team’s selection was our extensive cable-stayed bridge building experience, proven ability to work effectively in the water, and resources coming available from both joint venture partners just in time to transition smoothly to this project. Negotiations over final contract language will begin in the next few weeks, after which point we will receive formal award. NTP is scheduled for late this year with project completion in December of 2023.

The existing span is notorious locally for it's high incline, narrowness and lack of proper shoulders. Per the linked article, daily traffic had increased 40% between 2013 & 2016, leading to increased congestion. Expansion is also favorable due to increased shipping traffic in the Port of Houston, especially as the Port Commission approves additional infrastructure to serve modern Post-Panamax sized ships.
