The Jefferson Barracks Bridge, officially the Jefferson Barracks Memorial Arch Bridge, is a bridge that spans the Mississippi River on the south side of St. Louis. It is a pair of 909-foot (277 m) long arch bridges. The first bridge was built in 1983, and the south bridge opened in 1992. A delay occurred during the construction of the second bridge when a crane dropped a section of it into the river and it had to be rebuilt.
They replaced the former steel truss toll bridge built in 1941 that originally carried U.S. Route 50. It carries traffic for Interstate 255 (part of the St. Louis beltway) and U.S. Route 50. Prior to the construction of the first bridge, river crossings in this area were made via the Davis Street Ferry in the Carondelet neighborhood of St. Louis.
