Construction Update (6-15-18)

Between the Bishop Ford Freeway and the I-80 Toll Plazas, off-peak shoulder closures and lane closures in both directions, will be scheduled as needed.

Please check the Daily Construction Alert for up-to-date closure information.

Customer Impacts

Lane closures and traffic shifts are necessary to provide a work zone and safely accommodate construction.

At the I-80 Toll Plazas, no weekend closures are scheduled. At times, all open road tolling lanes may be closed and traffic routed through the cash lanes, where I-PASS is accepted. Cash lanes closures will be scheduled during off-peak, weekday hours and will not occur when open road tolling lanes are closed.


These roadway, bridge and ramp repairs are necessary to extend the life of the roadway and bridges and provide safe and convenient travel for Tollway customers.

Work Zone Safety

The Illinois Tollway is committed to ensuring that the South Tri-State Tollway (I-294/I-80) remains safe for both drivers and workers during construction, which is part of the agency’s overall commitment to roadway safety.

A 55 mph work zone speed limit will be in effect in areas with construction on the Tri-State Tollway.
