CHICAGO (CBS)– A wintry mix is creating icy conditions on roadways. A Winter Weather Advisory is in place for all counties, except Lake (IL) and McHenry counties.

CBS 2’s Marissa Parra reported she saw four cars that ended up in ditches along Illinois roadways before 5 p.m. She reported one incident on I-80 near Mokena, Illinois where icy roads led to a driver losing control.

The Illinois Tollway has warned drivers to slow down and allow extra times on the roads.

Police in Bartlett shut down eastbound Lake Street between Lambert Lane and Naperville Road due to icy conditions.

Power lines were on fire after heavy ice also caused trouble in suburban Northbrook.

At 10 p.m. Illinois State Police were reporting at least five significant crashes as they said many on the roads were driving too fast for the conditions.

People like Kate Crawford had to navigate in the nasty conditions.

“I deliver with Door Dash, so what I try to do is just make sure I’m taking my time,” she said.

But others were not as lucky as Crawford. During the day car after car on Interstate 80 careened into a ditch.

Lake County Illinois officials also described an uptick in crashes.

The silver lining is this happened on a holiday when overall traffic was significantly down.
