Construction Update (12/17/18)

Off-peak lane and shoulder closures will be scheduled as needed to complete pavement striping work. Please check the Daily Construction Alert for up-to-date closure information.


Customer Impacts

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

Whenever possible, the Tollway will use traffic shifts and shoulders to keep as many lanes open during peak hours as were available before construction. 


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. 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 Tollway is committed to “Building Green” and minimizing the environmental impact of construction by reducing, recycling and reusing materials. In addition to reducing the cost of this work, reuse of these materials reduces the need for virgin asphalt materials and reduces energy consumption, greenhouse gases and the volume of material that would otherwise be sent to landfills.

Work Zone Safety

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

Work 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. Visit the Tollway's Work Zone Safety page.
