I-490 Interchange Project
I-490/IL 390 Interchange Project
The Illinois Tollway is building a new, full-access interchange that will connect the new I-490 Tollway to the Illinois Route 390 Tollway and provide access to York Road, Irving Park Road, as well as direct access into and out of O’Hare International Airport.
The $340 million project includes construction of three miles of I-490 Tollway mainline roadway along with 16 ramps and 15 bridges to deliver full mobility on the west side of the airport. The new I-490/IL 390 Interchange is scheduled to be complete by the end of 2025.
In 2022, work on the I-490/IL 390 Interchange includes continuing construction of seven interchange ramps and bridges, as well as repair work on York Road. Construction also includes earthwork, drainage, retaining walls.
Lane closures and traffic shifts are necessary to provide a work zone and safely accommodate traffic during construction.
To accommodate interchange construction, a detour for York Road will be needed during bridge deck construction, as well as intermittent full closures along local roads during bridge beam placements.
Work Zone Safety
The Illinois Tollway is committed to ensuring that the Illinois Route 390 Tollway, as well as local roads, 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.
The new I-490 Tollway, coupled with the Illinois Route 390 Tollway, 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).
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.
