This bridge appears to be a 1940s-1960s, making it a late example of railroad bridge truss construction. It looks like the sorts of bridges present on the Calumet Sag Channel, which I did not have time to visit. The bridge is a subdivided, polygonal top chord 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.
