The Minerva Creek Bridge is located in Liberty Township north of Clemons, Iowa, United States. It spans Minerva Creek for 68 feet (21 m).[2] The Marshall County Board of Supervisors awarded a $14,090 contract to the N.M. Stark and Company of Des Moines to build six concrete bridges. They were all designed by W.W. Morehouse, the Marshall County Engineer. This single-span concrete Luten arch bridge was completed the same year for $2,550. It was the longest of the six bridges in the contract.[2] The bridge was listed on the National Register of Historic Places in 1998.[1]
