"The Ellsworth Ranch Bridge represents an unusual variation of a Pratt truss. It is identical to two trusses found in South Dakota and Minnesota, both built in the mid-1890s by Milo A. Adams, agent of the King Bridge Company. The only one of its type in Iowa, the Ellsworth Ranch Bridge is a rare surviving example of structural experimentation by one of the country's most prolific 19th-century bridge manufacturers."
