Construction

The Illinois Department of Transportation (Department) is currently in Phase II for this project.  Funding for Phase III is not included in the current program and the Department has no estimated timetable for implementation of the I-55 Managed Lane Project. When funding becomes available this site will be updated periodically as the project progresses. The Department wishes to thank you for your support and patience.
