Summary

Significance: The Freeport Bridge is one of the few unaltered examples remaining of what had once been the standard rural roadway bridge type of the 1870s in America, the bowstring arch-truss. This patented tubular arch design was marketed extensively throughout the United States and Canada by the Wrought Iron Bridge company, one of America's most important 19th century iron bridge fabricators. Among the bowstrings currently identified in America, the Freeport Bridge is second in span length only to a 183.5-foot structure in Blue Earth County, Minnesota, built by the Wrought Iron Bridge Company in 1873.
