Mark Twain Memorial Bridge

The Mark Twain Memorial Bridge is a steel truss structure spanning the Mississippi River between Missouri and Illinois with four traffic lanes. Its design distributes weight efficiently across the water to support the continuous flow of vehicles that cross daily.

The original bridge was built in 1936 during the Great Depression and opened by President Franklin D. Roosevelt. It was replaced by the current structure to meet modern traffic needs and safety standards.

The bridge connects Hannibal to the river that shaped one of America's greatest writers, serving as a physical link to literary heritage. As you cross, you pass over the same waters that once captivated the author's imagination during his youth.

The bridge functions as a main highway crossing with clear views of the river during passage. Be mindful of traffic patterns, especially during peak hours, to ensure a smooth driving experience.

A stone portrait of Mark Twain decorates the Missouri entrance, connecting the bridge to the celebrated author's legacy. This carved image greets travelers as a tribute to his influence on American literature and the region.
