The Ames Creek Bridge is a historic structure located northeast of DeWitt, Iowa, United States in rural Clinton County.
It is an early example of concrete bridge design prior to the codification of standards by the state highway commission.
The Clinton County Board of Supervisors contracted with Charlotte, Iowa contractor J.R. Kane in 1912 to build the bridge.
The bridge's concrete abutments and wing walls required almost 125 cubic yards of excavation.
[2] It was built a year before the Iowa State Highway Commission began developing standard bridge plans.
