Williamstown Bridge, Continuous truss bridge across Ohio River between Williamstown, West Virginia and Marietta, Ohio, United States
The Williamstown Bridge extends 2,615 feet across the Ohio River, featuring a main span of 651 feet and a deck width of 58 feet.
The first bridge at this location opened in 1903 and functioned as a toll crossing until 1937 when the West Virginia State Road Commission acquired it.
In 1902, the bridge construction site marked the location of the first United Steel Workers union strike in the United States.
The bridge carries West Virginia Route 31 and Ohio State Route 60 traffic, connecting to Ohio State Route 7 on the Marietta side.
The current structure, completed in 1992, ranks as the twenty-eighth longest continuous truss bridge in North America and reuses two original stone piers.
