The Mark Twain Memorial Bridge is the name for two bridges over the Mississippi River at Hannibal, Missouri, childhood home of Mark Twain, for whom the bridge is named. The current bridge, north of the original site, was finished in 2000; the original bridge, built in 1936, was demolished. The bridge currently carries traffic for Interstate 72 and U.S. Highway 36. The state of Missouri has put up a stone picture of Twain on the Missouri side of the bridge.
