Olympic Avenue Bridge

The Olympic Avenue Bridge is located northeast of Carroll, Iowa, United States. The 46-foot (14 m) span carries traffic on Olympic Avenue over an unnamed stream.[2] This bridge was one of 15 similar spans that Carroll County had built in 1913. The county board of supervisors contracted with the Standard Bridge Company of Omaha to build the Warren pony truss structures that were designed by the Iowa State Highway Commission (ISHC). They were supported by a timber substructure. These bridges became the prototype of what would become the ISHC's standard design.[2] Standard Bridge was paid $29,174 to build all the bridges. The estimated cost of this bridge was $1,208.[2] It was listed on the National Register of Historic Places in 1998.[1]
