Will County - I55 (Lorenzo Road) Project Study

The Illinois Department of Transportation (Department) is in the process of finalizing preliminary engineering and environmental studies (Phase I) for the improvement of I-55 at Lorenzo Road and at IL 129 in Will County. The general scope of work for this improvement is anticipated to consist of the reconstruction of the existing I-55 interchanges at Lorenzo Road and at IL 129, an addition of auxiliary lanes and drainage improvements.  The proposed scope of work also includes the permanent closure of West Frontage Road from Lorenzo Road to approximately 0.75 miles north of Kavanaugh Road.

Phase II (Design) consists of refining the design to develop contract plans and land acquisition. Phase III (Construction) consists of the actual construction of the project.
