Customer Impacts

Lane closures and traffic shifts 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. 

All-Electronic Interchange

The Illinois Tollway operates the nation's largest electronic tolling system, with more than 90 percent of all toll transactions paid electronically through I-PASS or E-ZPass. I-PASS customers experience faster, safer and more convenient commutes and save time and money.

As part of the I-294/I-57 Interchange Project, ramp toll collection provides cashless tolling with I-PASS or Pay Online lanes.

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.

Project Open House

The Illinois Tollway hosted a public open house on June 25, 2019, as part of the agency's ongoing work on the $719 million Tri-State Tollway (I-294)/I-57 Interchange Project.

The open house provided the opportunity for the Tollway to share 2019 construction information with customers, residents and businesses, as well as introduce the Illinois Tollway's ConstructionWorks Program designed to link job seekers with opportunities for rewarding careers in Illinois' high-demand transportation related construction industry.
