Description
This pair of polygonal Warren through trusses was built by the Rock Island Railroad to carry three tracks across the Calumet Sag Channel into Downtown Chicago. The east bridge carries two tracks, and the west bridge one track. It is just east of the Blue Island Yard 5 Bridges, and practically underneath the Western Avenue high bridge. Today they carry numerous Metra Rock Island Line commuter trains every day, and an occasional freight train. A commuter train station is at the north end of the bridges.
