The Original Mark Twain Memorial Bridge (1936-2000)

The Mark Twain Memorial Bridge spanned the Mississippi River, connecting Hannibal, MO with the State of Illinois at Aladdin. The bridge was a Public Works Administration project, opening in 1936, coincidentally as part of US Highway 36.

Before the bridge was built, automobiles could cross the Mississippi River at the nearby Wabash Bridge, which was built, and remains, as a railroad bridge.

Originally opening as a toll bridge, the tolls were removed in 1940.

In 2000, the bridge was demolished and replaced with a new bridge of the same name, carrying the newly-extended I-72 into Missouri, as well as US-36. A portion of the old Mark Twain Memorial Bridge remains is preserved at Cardiff Hill Overlook Park in Hannibal.

More pictures of the Bridge are available from the Library of Congress.

Thanks as always for reading!
