"A marked detour will be in place utilizing Illinois 143, Illinois 255, and Illinois 140," IDOT said. "This closure is to complete emergency slope repairs and installation of permanent sheet piling to stabilize the shoulder and roadway. Work is being completed by Keller Construction."
To avoid the work area, when feasible, the use of alternate routes should be considered. Drivers are urged to pay close attention to changed conditions and signs in the work zones, obey the posted speed limits, refrain from using mobile devices and be alert for workers and equipment.
