The Clark Bridge (sometimes referred to as the Super Bridge as the result of its construction being the subject of a documentary aired by NOVA) is a cable-stayed bridge across the Mississippi River between West Alton, Missouri and Alton, Illinois. The bridge was built in 1994 and carries U.S. Route 67 across the river. It is the northernmost river crossing in the St. Louis metropolitan area.

The new Clark Bridge replaces the old Clark Bridge, a truss bridge built in 1928, also named after explorer William Clark. The bridge carries four lanes of divided highway traffic, as well as two bike lanes, whereas the old bridge only carried two lanes (similar to the upstream Champ Clark Bridge).
