Dekalb County - Illinois 23 at Chicago Road
The Illinois Department of Transportation is in the planning and early phase of a study to improve the Illinois 23 and County Highway 16 (Chicago Road) intersection in DeKalb County. This project consists of reconstruction of the intersection into a roundabout.
The improvement is tentatively scheduled in the department’s FY 2025-2030 Highway Improvement Program, subject to project readiness and funding availability. During construction the west leg of Chicago Road is planned to be closed.
Please explore this page for further information regarding the improvement. There are additional location maps, crash exhibits, photos, and preliminary typical sections available.
Traffic will follow a detour using Rollo Road, Suydam Road and Somonauk Road.
Public involvement outreach - coming soon.
