8/26/19: U.S. 41 Northbound Traffic Update

Monday, August 26, 2019: 

Update as of 3 PM - 

The Illinois Department of Transportation announced that northbound U.S. 41 (Skokie Highway) between Lake-Cook Road and Park Avenue in Highland Park is reduced to one lane until Thursday.

The location is currently part of an ongoing resurfacing project. Due to rain creating slick conditions on the unpaved surface in the work zone, northbound U.S. 41 was closed this morning, but reopened to one lane at approximately 1:30 PM.

Both northbound lanes are expected to be paved and reopened by Thursday.

Motorists can expect slower speeds and should watch for wet and slippery pavement through the work zone, allowing extra time for trips through the area. The speed limit will be reduced to 45 mph. Drivers are urged to pay close attention to flaggers and signs in the work zones, obey the posted speed limits and be on the alert for workers and equipment.
