Construction continues on Burlington bridge over Tri-State Tollway

A train heading toward Chicago jogs onto the "shoofly" tracks built on top of a temporary bridge over the Tri-State tollway Tuesday morning. When complete, the new $96 million bridge will allow for expansion of several lanes of the tollway. When the temporary bridge is taken down, the railroad will add an additional track to the existing three. The fourth track will be for maintenance purposes by the railroad. Prior to the pandemic, an average 104 Metra and Amtrak trains and 52 freight trains crossed the bridge daily. (Jim Slonoff photo)
