Williams Brothers was contracted by the Texas Turnpike Authority to construct the $102M Jesse H. Jones Memorial Bridge, which is now the Sam Houston Tollway Ship Channel Bridge. The bridge is a cantilevered concrete trapezoidal haunched hollow box girder. At 1,560 feet in length and 59 feet in width, the bridge carries four lanes of traffic with the longest span at 750 feet. At the time of completion, the bridge was the longest box girder span in the Western Hemisphere.
