CARLOCK — The Illinois Department of Transportation announces that the on- and off-ramps at exit 120 on westbound Interstate 74 will close Friday, Oct. 19.

The closures are necessary so that new ramps can be built. Prior to the closures, the eastbound ramps at exit 120 will reopen. Traffic will be detoured to the Mitsubishi Motorway (U.S. 150) and Illinois 117 exits. Work is expected to be complete by the end of November.

Motorists can expect delays and should allow extra time for trips through this area. To avoid the work area, when feasible, 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.
