Central Tri-State Tollway (I-294)
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 2021 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 will be ongoing at two major bridges in this area: The Mile Long Bridge between Hodgkins and Willow Springs and the Burlington Northern Santa Fe (BNSF) Railway Bridge in Hinsdale and Western Springs. At both locations traffic, including freight and commuter rail traffic, will be maintained during construction.
Work this year also includes the reconstruction and improvement of ramps at the I-55 Interchange and several ramps and bridges providing access to Archer Avenue, , including construction of a new ramp connecting westbound Archer Avenue to northbound I-294. Construction is also underway 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 will include coordination with the Flagg Creek Water Reclamation District to relocate existing sewer lines adjacent to I-294 in advance of mainline roadway reconstruction and widening.
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 (7/30/21)
Between the Bensenville Railyard Bridge and Wolf Road, traffic in both directions is shifted, including one southbound lane that is traveling on the northbound side of the Tollway. Southbound traffic entering the counterflow lane at the Bensenville Yard Railroad Bridge 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 through 2021.
Between Ogden Avenue and 55th Street, traffic in both directions is shifted. Traffic is scheduled to remain in this configuration through 2021.
Between the Hinsdale Oasis and I-55, off-peak closures will be scheduled in various locations, as needed, for work on the relocation of Flagg Creek Water Reclamation District sewer lines.
Between Plainfield Road and 75th Street, traffic is reduced to three lanes in both directions with all traffic shifted onto the northbound side. Access to and from 75th Street I-55 and Wolf Road will remain open during construction. Southbound traffic traveling to 75th Street should be prepared to access to the exit in advance of the ramp. Traffic is scheduled to remain in this configuration through 2021.
Between 5th Avenue and Archer Avenue, southbound traffic is shifted. Traffic is scheduled to remain in this configuration until end of 2022.
The ramp connecting eastbound Archer Avenue to southbound I-294 is closed through September. A detour will be posted. The ramp connecting westbound Archer Avenue to southbound I-294 is scheduled to close Saturday, July 31, through early September. A detour will be posted. Additional ramp closures and detours will be in place intermittently at the Archer Avenue Interchange.
Between the 83rd Street Toll Plaza and 95th Street traffic in both directions is shifted with two northbound lanes traveling in counterflow lanes on the southbound side of I-294. Traffic is scheduled to remain in this configuration through summer.
Between 82nd Street and LaGrange Road traffic is shifted in both directions. Traffic is scheduled to remain in this configuration through summer.
Please check the Daily Construction Alert for up-to-date closure information.
I-290 & Local Roads
Traffic on Butterfield Road is reduced to a single lane in both directions under I-294, between Calvin Avenue and I-290. The closure is scheduled to remain in place through the end of 2022.
On Joliet Road, between I-55 and I-294 in Indian Head Park, one land in both directions on Joliet Road is closed. Traffic is scheduled to remain in this configuration into fall.
Traffic is also shifted on several ramps at the Archer Avenue Interchange through summer 2021, and lane closures on local roads will include:
- 79th Street between Oak Grove Avenue and Archer Avenue will be reduced to two lanes in both directions.
- Westbound Archer Avenue will be reduced to one lane between Oak Grove Avenue and westbound 79th Street ramp.
- Eastbound Archer Avenue at LaGrange Road will be reduced by one lane, as will the ramp from eastbound Archer Avenue to 79th Street.
- Northbound LaGrange Road will be reduced to one lane.
Roberts Road and 87th Street under I-294 are both reduced to a single lane in both directions with designated turn lanes available. Traffic will remain in this configuration into 2022. In addition, overnight full closures are scheduled to begin the week of July 26, for bridge beam placement and continue through early August.
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.
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.
