Middle Creek Bridge, Spanning Middle Creek at Ventura Road, Rose Hill, Mahaska County, IA

Significance: The Middle Creek Bridge, a 4-panel Pratt pony truss, is one of only four bridges remaining built by Seevers Manufacturing Company, based in Oskaloosa, Iowa. The use of steel pipe for the upper chord was a standard design for the company, which also manufactured steam pipes. This bridge is an excellent example of the company's work, an unusual structural type designed and fabricated by a small-scale Iowa company.
