Notes

Building/structure dates: 1935 initial construction
Building/structure dates: 1964 subsequent work
Significance: All five bridges are identical to one another and employ double tracks, except for the center bridge, which has only a single track. The Indiana Harbor Belt Railroad and the Baltimore & Chicago Terminal Railroad rail bridges are adjacent to each other on the western side of the group, while the three bridges to the east are the property of the Grand Trunk Western Railroad. The bridges are steel, fixed span through bridges with Pratt trusses. Members are connected by riveted gusset plates with plates and angles forming I-beams. There are concrete piers and abutments. Each bridge has one main span about 200' long. Bridges have concrete retainer walls and fenders. There is a concrete culvert west of bridges on north bank.
