Project Description: Preparation of a Project Report and right of way plans for the improvement of IL 47 from north of I-80 to the US 52 intersection. This project involves the widening, resurfacing and addition of safety slopes along an existing two-lane highway. The south end connects to a commercial area north of the I-80 interchange which will be widened to provide a center turn lane. Due to heavy truck traffic from Chicago, the major intersections are being designed for WB-65 vehicles, including channelization. Areas of roadway flooding are being evaluated. Bridges and culverts are being inspected and checked for adequacy, extension or replacement. Phase II Design will follow the approval of the Project Report.
