Central Tri-State Tollway (I-294)

Central Tri-State Tollway (I-294) Project

Project Overview

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. This 22-mile corridor serves more than 300,000 vehicles daily. The $4 billion project is scheduled from 2018 through 2026.

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.

2023 Overview

Construction in 2023 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 Mile Long Bridge between Hodgkins and Willow Springs is scheduled to be complete this year. 

Work this year also includes ongoing work to reconfigure ramps at the Ogden Avenue Interchange, reconstruction and improvement of ramps at the I-55 Interchange and work to reconfigure the ramps at the I-290/I-88 Interchange at I-294.

In addition, work to reconstruction of the Plainfield Road Bridge carrying traffic over I-294 is scheduled for completion this year, as is bridge reconstruction and local road improvements at 87th Street and Roberts Road.

Construction Update (5/25/23)

I-294 Mainline
Between the O'Hare Oasis and Plainfield Road traffic is currently shifted in both directions, including:

  • Between North Avenue and St. Charles Road, one southbound lane is traveling on the northbound side of the Tollway.
  • Between North Avenue and Wolf Road, two northbound lanes are traveling on the southbound side of the Tollway.
  • Between Maple Avenue and Ogden Avenue, four northbound lanes of traffic are shifted to the left and one lane is shifted to the right with a work zone in the middle. All exiting traffic must use the right lane well in advance of the interchange to access both eastbound and westbound Ogden Avenue.

Traffic is scheduled to remain in this configuration through fall 2023.

Between Plainfield Road and 75th Street, traffic in both directions is shifted and reduced to three lanes. Traffic is scheduled to remain in this configuration through spring 2023.

In conjunction with work at the 88th/Cork Avenue Interchange, the ramp connecting eastbound Archer Avenue to southbound I-294 is closed through 2025. A detour is posted

Between the Mile Long Bridge and 88th/Cork Avenue, traffic in both directions is shifted.

Please check the Daily Construction Alert for up-to-date closure information.

Local Roads
On Butterfield Road, traffic is reduced to a single lane in both directions under I-294 between Calvin Avenue and I-290. The closures are scheduled to remain in place through 2024.

Ramps
At the I-290/I-88 Interchange at I-294:

  • The ramp connecting northbound I-294 to westbound Roosevelt Road is closed to traffic. A detour will be posted. The ramp is scheduled to remain closed through the end of 2023.
  • The ramp carrying traffic from westbound I-290 to northbound I-294 is closed. A detour is posted. The ramp is scheduled to remain closed through the end of 2024.
  • The ramp carrying westbound Roosevelt Road to southbound I-294 is closed for ongoing work to reconstruction the I-290/I-88 Interchange at I-294. A detour will be posted. The ramp is scheduled to remain closed through the end of 2024.
  • Additional lane and ramp closures are scheduled throughout the year on I-294 and I-290. Detours will be posted.

Customer Impacts

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.

Visit the Central Tri-State Tollway (I-294) outreach page.

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.

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.
