State Highway No. 78 Bridge at the Red River

The State Highway 78 Bridge spans the Red River with eight through truss sections, connecting Oklahoma and Texas along State Highway 78.

Built during the Great Depression as part of Roosevelt's New Deal, this bridge replaced a suspension structure that collapsed in a 1934 storm.

The bridge represents Depression-era engineering practices and stands as a K-Parker through truss design with distinctive camelback pony spans.

The structure extends 2,108 feet in length, features a 24-foot deck width, and serves approximately 1,700 vehicles crossing between states daily.

Illinois Steel Bridge Company fabricated the trusses, while the Kansas City Bridge Company constructed this federal relief project at Sowell's Bluff.
