The NRHP nomination for the bridge asserts:

Before the codification of bridge design in the state in 1913, Stark built perhaps hundreds of Luten arches throughout Iowa, in exclusive contracts with Story and other counties. This structure in Story County is distinguished as the earliest remaining Luten arch in the state. In fact, with its 1905 construction date, it is one of the oldest Luten arches in the country, built in the same year as Daniel Luten received his patent. For this reason, it is a technologically significant, transportation-related resource.[2]^:5
