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.

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.
