Sam Houston Ship Channel Bridge
Sam Houston Tollway Ship Channel Bridge (formerly known as the Jesse H. Jones Memorial Bridge) is a bridge in Harris County, Texas. It was acquired from the then–Texas Turnpike Authority (TTA) (now North Texas Tollway Authority) on May 5, 1994, and is now a part of the Harris County Toll Road Authority system. The bridge opened to traffic in May 1982. It carries four lanes of Beltway 8 over the Houston Ship Channel with a clearance of .

The 1952 City of Houston planning document recommended a second loop designated the Outer Belt. Harris County took control of the project in 1960. Efforts to construct the Beltway 8 crossing started in the mid-1960s, culminating in an effort vetoed by Governor John Connally on June 18, 1967. Voters twice rejected bond funds for the bridge, so the effort was reconstituted as a toll bridge. This did not work at that time.
In 1978, the Texas Turnpike Authority performed a study showing the project as feasible, and sold $102M (approximately $333.1M in 2008) of bonds to fund it.
Among designs looked at, a cable-stayed design was studied, but not sufficiently understood at the time. Such was later used on the Fred Hartman Bridge, but in 1978 when this bridge was designed, the only U.S. example of a cable-stayed bridge was the Ed Hendler Bridge, meaning there was a deficiency of design and construction experience for the bridge type.
