The Old Clark Bridge was a bridge that carried U.S. Route 67 across the Mississippi River between West Alton, Missouri and Alton, Illinois. It was constructed beginning in 1927, was replaced by the Clark Bridge and was demolished in 1994. The bridge was initially a toll bridge.[http://www.modot.org/newsandinfo/publications/documents/1930.pdf Map of Missouri Showing State Road System] {{Webarchive|url=https://web.archive.org/web/20120916165545/http://www.modot.org/newsandinfo/publications/documents/1930.pdf |date=2012-09-16 }}, January 1, 1930
