Tri-State Tollway — I-294, I-94, and I-80

While there are currently no major construction projects anticipated, this corridor has two large mitigation projects:

  • The Illinois Tollway is conducting a wetland restoration project on a 160-acre site owned by the State of Illinois in North Chicago. The site is located just south of Buckley Road (IL Route 137) between IL Route 41 and IL Route 43 and east of the Tri-State Tollway (I-94). Our team continues to monitor the North Chicago Mitigation Bank.

  • The Illinois Tollway partnered with the Forest Preserve District of Cook County (FPDCC) to implement a stormwater demonstration project along the North Tri-State Tollway in northern Cook County. Our team continues to monitor the bioswales.
