I finally found records giving a history of this structure. It appears it was built as a hinge span to the eastern Pile-Pontoon Bridge at Prairie du Chein, Wisconsin in 1898 and moved here in 1913. The hinge detail would explain the unusual shape on one end.

This bridge bears a resemblance to a bridge in my hometown:

The Minnesota bridge was built using girders that were rebuilt for road use. It would not surprise me if that was the case here as well.
