This project involves improvements on U.S. Route 45 between IL 132 and IL 173, with special focus on the Grass Lake Road and Millburn Road intersections in the vicinity of the Millburn Historic District. Much to the chagrin of local residents, the chosen route for the bypass passes through two village subdivisions. The alternative route, favored by a vast majority of residents, passed primarily through empty farm fields. Nevertheless, land acquisition is ongoing.
