The Illinois Department of Transportation says more than 170 salt trucks were deployed Saturday night, but the area is still seeing still plenty of traffic accidents.
In north suburban Skokie, two cars collided at Dempster and McCormick. Slick streets are believed to be a factor there.
Meantime, northbound inner Lake Shore Drive had to be shut down between Division and North Avenue due to a three-car crash.
The southbound off-ramp at North Avenue was also closed due to ice.
