Mark Twain Memorial Bridge, Steel truss bridge across Mississippi River in Hannibal, United States
The Mark Twain Memorial Bridge stretches 4,491 feet over the Mississippi River, incorporating four traffic lanes that connect Missouri and Illinois through Interstate 72.
The original structure, built in 1936 during the Great Depression, was inaugurated by President Franklin D. Roosevelt before being replaced by the current bridge in 2000.
The bridge stands near Hannibal, Missouri, the childhood home of Samuel Clemens, carrying his literary name across the waters that influenced his writings.
The structure accommodates approximately 11,000 vehicles daily, serving as an essential connection point between Missouri and Illinois through U.S. Highway 36.
A stone portrait of Mark Twain decorates the Missouri entrance of the bridge, marking the connection between the infrastructure and the celebrated author.
