Central Tri-State Tollway (I-294) Project
The Central Tri-State Tollway (I-294) is being reconstructed and widened from Balmoral Avenue to 95th Street to provide congestion relief, reconstruct old infrastructure to meet current and future transportation demand and address regional needs. The project is scheduled from 2018 through 2026.
Construction in 2022 includes mainline rehabilitation and widening between the O’Hare Oasis and Wolf Road and mainline reconstruction and widening between Wolf Road and St. Charles Road, between I-55 and 75th Street and between LaGrange Road and 95th Street. Work on the Burlington Northern Santa Fe (BNSF) Railway Bridge in Hinsdale and Western Springs is scheduled for completion this year, while work on The Mile Long Bridge between Hodgkins and Willow Springs is scheduled to continue. At both bridge locations traffic, including freight and commuter rail traffic, will be maintained during construction.
Work this year also includes work to reconfigure ramps at the Ogden Avenue Interchange, as well as ongoing reconstruction and improvement of ramps at the I-55 Interchange and completion of construction at the St. Charles Road Interchange on I-290 as part of the work to reconfigure the I-290/I-88 Interchange at I-294.
In addition, advance work, utility work and improvements to ramps and local crossroad bridges will take place throughout the project corridor. This work includes the reconstruction of the Plainfield Road Bridge carrying traffic over I-294, the removal of the Hinsdale Oasis over-the-road structure and the completion of the new pedestrian bridge over I-294 adjacent to 47th Street between Hinsdale and Western Springs for pedestrians and bicyclists.
The Illinois Tollway has undertaken a detailed planning and refinement process to develop design and construction plans for the Central Tri-State Tollway Project. Major components of the project include reconfiguring the I-290/I-88 Interchange at I-294, rebuilding the Mile Long Bridge and the BNSF Railway Bridge, as well as integrating Flex Lanes and SmartRoad technology.

Construction Update (5/13/22)
Between North Avenue/Lake Street and the O'Hare Oasis traffic is shifted in both directions, including one southbound lane that is traveling on the northbound side of the Tollway between Grand Avenue and St. Charles Road and one northbound lane that is traveling on the southbound side of the Tollway between Franklin Street to the O'Hare Oasis. In addition, southbound traffic entering the counterflow lane at Grand Avenue will not be able to change lanes until just past St. Charles Road and will not have access to the exit to westbound I-290. Traffic is scheduled to remain in this configuration into the summer.
Between 31st Street and Salt Creek, northbound traffic is shifted. Traffic is scheduled to remain in this configuration until fall.
Between the Hinsdale Oasis and I-55, southbound traffic is shifted and reduced to three lanes. Traffic is scheduled to remain in this configuration through 2022.
Between I-55 and Joliet Road, traffic in both directions is reduced to three lanes and all traffic is shifted onto the southbound side of the Tollway. Traffic is scheduled to remain in this configuration through fall.
The ramp connecting eastbound Archer Avenue to southbound I-294 is closed through 2022. A detour will be posted. Additional ramp closures and detours will be in place intermittently at the Archer Avenue Interchange.
Between the Mile Long Bridge and 95th Street, traffic in both directions is shifted. Northbound traffic is split with two lanes shifted into the southbound side in a counterflow configuration and two lanes shifted to the left with a workzone in the middle. Traffic is scheduled to remain in this configuration through summer.
Please check the Daily Construction Alert for up-to-date closure information.
I-290, I-55 & Local Roads
On St. Charles Road, one lane in each direction is closed. Traffic is scheduled to remain in this configuration through summer.
Traffic on Joliet Road traffic is reduced to one lane in each direction under I-294. Traffic is scheduled to remain in this configuration through summer.
Traffic on Roberts Road and 87th Street is reduced to a single lane in both directions under I-294. Periodic overnight full lane closures will occur through March. Detours will be posted.
Removal of the Hinsdale Oasis over-the-road building is currently underway and will be followed by removal of the bridge structure in early summer, with all work at the oasis anticipated to be complete by the end of fall. On I-294, traffic is shifted to safely accommodate this work, and roadway closures will be scheduled as needed during overnight hours to reduce the disruption to daily commuters.
Shoulder closures and traffic shifts will be used to provide room for a work zone and safely accommodate traffic. Whenever possible, the Tollway uses traffic shifts and shoulders to keep as many lanes open during peak hours as were available before construction.
In addition, lane closures will be scheduled as needed on the Tollway and local roads to complete work.
To accommodate roadway reconstruction and widening, the project will require the removal of the over-the-road building and bridge at the Hinsdale Oasis in 2022. The remainder of the oasis will remain open to Tollway customers during and after construction is complete, with parking as well as the 7-Eleven fuel stations with food, restrooms and fuel accessible for customers on both sides of I-294.

A Regional Solution
The Central Tri-State Tollway is being reconstructed to increase capacity, reduce congestion and improve travel reliability. This work is part of the Tollway’s 15-year, $14 billion capital program, Move Illinois: The Illinois Tollway Driving the Future. More than 220,000 vehicles use this portion of the Tri-State Tollway daily.
A detailed planning and refinement process is underway to complete a design concept for rebuilding the Central Tri-State Tollway (I-294). This process includes outreach efforts with customers, communities, businesses and partners to identify regional improvements and continue to refine the design details.
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 that the Central Tri-State Tollway (I-294) and local roads remain 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.
