The improvements also include the widening and reconstruction of the IL-104 Bridge over the McGee Creek Drainage Ditch, mechanically stabilized earth retaining walls at the east approach of the Illinois River Bridge, a new bridge over Washington Street, reconstruction of the intersection of IL-99, and the reconstruction of Main Street and the connection at Marion Street, a new pumping station, a new drainage system and roadway lighting.
