The Wabash Bridge carries one railroad track across the Mississippi River between Hannibal, Missouri, and Pike County, Illinois. Built by the Wabash Railroad, the bridge is today owned by the Norfolk Southern Railway. Built as a swing span, the bridge was converted in 1994 to a vertical lift bridge to increase the width of the navigational channel. The vertical lift span was taken from a bridge over the Tennessee River at Florence, Alabama. To minimize the effect on river traffic, the new span was installed over the course of three days.
