The 143rd St Corridor Improvements is a series of projects to reroute Illinois Route 126 onto 143rd Street, away from downtown Plainfield. These projects fulfill the Village’s Comprehensive Plan and Transportation and Mobility Plan vision of reducing congestion in the downtown area and creating opportunities for growth west of Plainfield. The initial projects will close gaps along the corridor while future projects will increase capacity along the existing corridor.
