Construction Update (4/8/19)

On I-88, mainline and ramp shoulder closures are scheduled during off-peak hours to complete electrical work, as well as roadway lighting, signage and fence work.

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

Customer Impacts

On I-88, traffic will be reduced from two lanes to one lane to provide room for the majority of the work zone during construction throughout the majority of the resurfacing project. The shoulders in the work zone are too narrow to safely accommodate a traffic shift. Closures will also be scheduled on local crossroad bridges and ramps to accommodate construction. 


Pavement resurfacing will provide customers a smoother surface, improving the overall driving experience, and extend the life of the roadway. This work is part of the Tollway’s 15-year, $14 billion capital program, Move Illinois: The Illinois Tollway Driving the Future

Building Green

The Illinois Tollway is committed to "Building Green" and minimizing the environmental impact of construction by reducing, recycling, and reusing materials. Reusing materials reduces the volume of material that otherwise would be sent to landfills.

Work Zone Safety

Construction zone speed limits are in effect in all construction zones 24/7, and drivers should continue to watch for changing traffic patterns and use caution, especially when workers are present. A 45 mph work zone speed limit will be in effect on I-88 throughout the repair project.  Work zone speed limits will also be in place on ramps and local crossroad bridges.
