WIDOT Rock County IH 90/39 and IH 43 Interchange Reconfiguration

This $114 million project near the border of Wisconsin and Illinois is located at the interchange of three highways: Interstate-90/39, Interstate-43, and State Highway 81. Our scope includes the demolition of existing electrical systems and installing new traffic signals, lighting, and ITS (intelligent traffic systems). There is a robust coordination effort between trades on this project because of the number of new structures to be built.
