The Illinois Tollway has started to rebuild the Mile Long Bridge on Interstate 294 in the southwest suburbs, using both steel and concrete beams.

The bridge carries traffic over two major railroads, the Des Plaines River, the Chicago Sanitary and Ship Canal, the Illinois & Michigan Canal and local roads. Tollway officials said using the longer beams means fewer piers are needed to hold up the bridge, which will make the project more cost-efficient and environmentally friendly.

The Mile Long Bridge is one of the first major construction segments for the $4 billion Central Tri-State Tollway (I-294) reconstruction project.Workers install massive beams over the Chicago Sanitary and Ship Canal on Interstate 294’s Mile Long Bridge in Willow Springs on June 5, 2020.
