Mark Twain Memorial Bridge, Road bridge across Mississippi River in Hannibal, US
The Mark Twain Memorial Bridge spans 4,491 feet across the Mississippi River, featuring four traffic lanes that connect Missouri with Illinois.
The original structure, opened in 1936 by President Franklin D. Roosevelt, served as a vital crossing point until its replacement in 2000.
A stone carving of Mark Twain decorates the Missouri entrance, reflecting the connection to the author who spent his childhood in Hannibal.
The bridge carries Interstate 72 and U.S. Highway 36 traffic, accommodating approximately 11,000 vehicles daily across the Mississippi River.
The bridge replaced a dangerous sharp curve on the Missouri approach, incorporating modern safety features in its 86-foot-wide design.
