I-490 Tollway

I-490/I-294 Interchange Project

As part of the new I-490 Tollway, the Illinois Tollway is building a new interchange connecting I-490 to the Tri-State Tollway (I-294).

In 2024, work will include completing the remaining retaining walls and bridges over Grand Avenue, the Union Pacific Railroad and North Avenue/Lake Street. In addition, work will include reconstruction of mainline pavement on northbound I-294 and completion of the flyover bridge from northbound I-294 to northbound I-490.

The work is anticipated to be completed by early 2025.

Construction Update (2/3/25)

Local Roads
Westbound Lake Street is closed at I-294 and a detour is posted. Traffic is scheduled to remain in this configuration through summer 2025. 

See the Daily Construction Alert for up-to-date information.

Customer Impacts

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

Electronic message signs and construction signage will be put in place in advance to alert drivers to scheduled lane closures, traffic patterns and work zone speed limits.

To accommodate interchange construction, lane closures on local roads will also be needed.

Work Zone Safety

The Illinois Tollway is committed to ensuring that the 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 at illinoistollway.com.

Purpose

The new I-490 Tollway, coupled with the Illinois Route 390 Tollway, which was completed in 2017, will connect businesses and communities with one of the nation’s busiest airports, transit facilities, major freight transportation hubs, distribution centers and multiple interstate highways including the Jane Addams Memorial Tollway (I-90) and the Central Tri-State Tollway (I-294).

Sustainability

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.
