Illinois Tollway to Begin Resurfacing, Interchange Construction Project


City Encourages the Public to Plan Ahead

In April, the Illinois State Toll Highway Authority (ISTHA) will begin work to resurface the
Reagan Memorial Tollway (I-88) from Sugar Grove to Rochelle. This project also includes
rehabilitation of ramps and bridges, which will require intermittent closures at the Annie
Glidden Road Interchange and the Peace Road Interchange.

The ISTHA has coordinated with the City to establish a detour route through the City. The
detour established by ISTHA will route traffic between Annie Glidden Road and Peace
Road via Lincoln Highway (IL 38). This may result in increased traffic volume, including
additional truck traffic, on Annie Glidden Road, Lincoln Highway, and Peace Road in
DeKalb. I-88 will remain open throughout the project, and traffic is not being diverted off
I-88 through DeKalb as it may appear on the attached map.

The tentative schedule provided by ISTHA indicates that work on the Annie Glidden Road
Interchange will begin in April, followed by the Peace Road Interchange in July. Ramp
closures will be limited to one interchange at a time.

This project is fully managed and funded by the ISTHA. The City of DeKalb has no
authority over project planning or scheduling of work. The ISTHA has provided the
following resources for the public to stay informed:

  • – Explore Projects section, live roadway images, and real-time
    roadway incident information.
  • Daily construction alerts — Daily and long-term lane and shoulder closure schedules.
  • – Real-time travel times.
  • – Real-time roadway incident information at Tollway Trip 88.
