Project Overview


Two contracts have been awarded for the reconstruction and widening of US 12/45 (Mannheim Road) from north of IL 19 (Irving Park Road) to I-190 and from I-190 to just north of IL 72 (Higgins Road). The road will be widened from its current 2 lanes to 3 lanes in each direction. These two sections of Mannheim Road are approximately 3.2 miles in total length. There are 4 major intersections along Mannheim Road within the project limits. They include Montrose Avenue, Lawrence Avenue, Zemke Boulevard, and Higgins Road (IL 72) along with the I-190 interchange. Also included as part of this project is the construction of a Balmoral Underpass that will allow access from southbound Mannheim Road to eastbound Balmoral Avenue. Currently there is only access from northbound Mannheim Road to eastbound Balmoral Avenue.


The project calls for the removal of the existing 4 lane roadway and replacement with a 6 lane finished concrete pavement with shoulders along the roadway on Mannheim Road. Included will be upgraded drainage facilities, new lighting, new signing and water main relocation. The traffic signals at Montrose Avenue, Lawrence Avenue, Zemke Boulevard and Higgins Road  will be replaced. Included is the construction of a Balmoral Avenue underpass which will provide access from southbound Mannheim Road to eastbound Balmoral Avenue.


60G37- Mannheim Road (from Illinois Route 19, Irving Park Road to I-190)

60P35- Mannheim Road (from I-190 to Illinois Route 72, Higgins Road)


During construction, a total of 4 stages are proposed. During each stage, the existing number of traffic lanes along Mannheim Road in the northbound and southbound directions will be maintained at 2 lanes in each direction. Occasional temporary lane closures will be allowed during midday and overnight hours.

Detours will be posted for anticipated ramp closures at I-190 Interchange to facilitate proposed construction. A tab labeled as “Detour” will be added to this site once a firm schedule has been developed. It will include timing of the detours as well as a plan showing the detour routes.


It is estimated that approximately 650 jobs will be created as a result of this project.
