This bridge's through truss main span is a textbook Wrought Iron Bridge Company bridge, meaning it retains unparalleled historic integrity and is essentially an exact copy of a design that can be found in catalogs for the company at the time. Most noteworthy is it retains the distinctive cast iron caps over the top chord / end post connection at the hip vertical, which the company placed on bridges built during this period. Cast iron bearing plates and bridge shoe details are present on this bridge. It also is very noteworthy for its approach span, which is an extremely rare example of a Queenpost truss.

Discussion of Bridge
In the 1870s Winneshiek County embarked on an
ambitious bridge construction program, in which many of the earliest
wooden structures were replaced with more substantial iron spans on
stone substructures. Beginning in 1873, the county, under the direction
of bridge commissioner George Winship, built several bowstring
arch-trusses, most of which were supplied by the Wrought Iron Bridge
Company, of Canton, Ohio.
