Tri-State Tollway (I-294)

I-294/I-57 Interchange Project - Phase 2

On Sunday, September 11, the Illinois Tollway opened the final ramps to provide full access at the Tri-State Tollway (I-294)/I-57 Interchange, two years ahead of schedule. The $719 million project built in partnership with the Illinois Department of Transportation delivers a new gateway for commerce and economic development in the Chicago Southland region.

The Tollway opened up traffic access to four new ramps connecting southbound I-57 to I-294 and I-294 to northbound I-57. The first phase of the interchange opened in 2014 with access from northbound I-57 to northbound I-294 and southbound I-294 to southbound I-57, including new ramps at 147th Street.

“Illinois is consistently ranked as one of the best states in the nation for infrastructure, and projects like this demonstrate why,” said Governor JB Pritzker. “These historic investments in our interstates and the effective partnerships that have emerged from them have opened a pathway to economic growth that will benefit the entire region. We’re telling businesses and new development that Illinois is a state where you’ll be given the infrastructure needed for success.”

Construction Update (11/28/22)

The final four new ramps connecting southbound I-57 to I-294 and I-294 to northbound I-57 are now open.

On I-57, traffic between Thornton Road and 147th Street is shifted in both directions for work to widen the CSX Railroad Bridge on I-57. Traffic is scheduled to remain in this configuration into 2023.

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

Customer Impacts

Lane closures and traffic shifts on I-57 and I-294 will be necessary to provide a work zone and safely accommodate construction.

Whenever possible, the Tollway uses traffic shifts and shoulders to keep as many lanes open during peak hours as were available before construction. 

Toll Collection

The I-294/I-57 Interchange includes ramp toll plazas that provide for cashless tolling with I-PASS or E-ZPass or customers have a 14-day grace period to pay online, before the Illinois Tollway issues invoices with additional fees.

New ramps with toll plazas include the ramp connecting southbound I-57 to northbound I-294 and the ramp connecting southbound I-294 to northbound I-57.

Additional tolled ramps at the interchange include the ramp connecting northbound I-57 to northbound I-294 and southbound I-294 to southbound I-57, as well as 147th Street to northbound I-294 and southbound I-294 to 147th Street.

The regular toll rate is $1.50 for customers who pay their unpaid tolls online within 14 days and a discounted rate of 75 cents offered to I-PASS or E-ZPass customers. Truck and trailer rates range from $1.50 to $4.00 during daytime hours, with overnight discounts offered.

Work Zone Safety

The Illinois Tollway is committed to ensuring that the Tri-State Tollway (I-294) and I-57 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. On I-294, a 45 mph work zone speed limit is in effect throughout the construction season.
