Bridgeport Bridge, Spanning Wisconsin River at U.S. Highway 18, Bridgeport, Crawford County, WI

Significance: In 1983, the Bridgeport Bridge, comprised of seven truss spans, was one of five remaining Pennsylvania trusses in the State of Wisconsin. However in the subsequent ten years, four of these uncommon truss bridges including the Bridgeport Bridge have been demolished. The Bridgeport Bridge was impressive in its overall length of 3400 feet, including one span over the slough, an intervening island, and nine spans over the main channel. Together with the Marquette-Prairie du Chien Bridge over the Mississippi River, begun in the same year, the Bridgeport Bridge represented the key to an improved transportation link between Iowa and Wisconsin.
