This bridge is technologically significant as a good representative example of a pin-connected through truss bridge, and is further significant as a well-decorated bridge that retains its decoration. These decorations include detailed portal cresting which sits atop an A-frame portal bracing, as well as beautiful cast iron caps that include decorative spherical finials and list the 1892 date for the bridge. A builder plaque also remains on the bridge. The bridge is also historically significant as an example of a bridge built by a local Iowa bridge company.
The bridge has been altered by the replacement of its original floorbeams, but the truss structure above the deck remains in original condition. Stringer approach spans are not all original.
Information and Findings From Iowa's Historic Bridge Inventory
Discussion of Bridge
in the small town of Fort Atkinson in southwestern Winneshiek County,
this medium-span truss carries a county road over an intermittent
stream. The structure dates to 1892. That year the Winneshiek county
Board of Supervisors let a series of private contracts for fabrication
and erection of this 135-foot, pinned Pratt truss. As indicated by a
plate on the bridge itself, it was built by D.H. Young of Manchester,
Iowa. County records do not reveal the total cost of the bridge. Called
the Fort Atkinson Bridge locally, this steel truss features a Pratt
configuration and is supported by a timber and concrete substructure.
This early Winneshiek County bridge continues to carry local traffic
with partial substructural and approach span replacement as the only
alterations of note.
