The Champ Clark Bridge is a five-span truss bridge over the Mississippi River connecting Louisiana, Missouri with the state of Illinois; it carries US Route 54 northeast to Pittsfield, Illinois where US Route 54 ends. The bridge, built in 1928, is a narrow two-lane bridge on a 20-foot deck. The bridge, originally painted silver, was repainted deep green in 1983, and repaired in 1999. In 2005, MoDOT rehabilitated and painted the bridge, replacing the green with gray. The bridge is 2,238.4 feet in length and the span over the main channel of the Mississippi River is 418.5 feet in length. The bridge is named after James Beauchamp Clark, a former Speaker of the House from Bowling Green, Missouri. Clark served as Speaker from 1911 to 1919.
