This bridge appears to be a 1950s-1970 truss bridge, making it a late example of railroad bridge truss construction. It is stylistically similar to the majority of railroad bridges present on the Calumet Sag Channel. The bridge is a polygonal Warren through truss with riveted connections. Deck plate girders provide an approach to the structure, which sits on concrete piers. There is lattice present on the bracing. The portal bracing is an a-frame design.
Thanks to Tom Winkle for providing boat transportation to assist in the photo-documentation of this historic bridge.
