Snow wreaked havoc for Chicago-area drivers Saturday. Regina Waldroup reports.
All lanes have reopened after a rollover accident shut down southbound lanes of the Dan Ryan Expressway near 79th Street Saturday morning.
Illinois State Police said they were investigating after a semi-tanker rolled over in an incident involving one other car near 83rd Street.
The Illinois Department of Transportation and the Chicago Fire Department were at the scene.
Fire officials said they were on standby at the scene while "non-hazardous material" was being loaded off the vehicle.
Traffic was being diverted off exits at 75th and 83rd Streets as lane closures begin at 79th Street.
No serious injuries were reported in the accident, but the lanes remained closed for several hours.
Officials reopened the lanes just after 4:30 p.m.
ISP issued a weather advisory Saturday warning drivers of hazardous road conditions and began implementing their emergency snow plan.
"The possibility of heavy snow fall, high winds, whiteout conditions, and deteriorating road conditions are likely," the advisory read. "Motorists are encouraged to allow for extra travel time in order to reach their destination safely."
The Illinois Department of Transportation announced Saturday that roads and bridges are snow and ice-covered in more than 50 percent of Illinois from the Northern border to Interstates 72 and 74.
IDOT advised motorists to only travel "if absolutely necessary."
"Our winter weather crews are seeing snow drifts as high as 10 feet making some Illinois roads very narrow and potentially dangerous for travelers, especially at nighttime in rural areas," said Illinois Transportation Secretary Ann Schneider. "With the high winds forecasted, blowing and drifting snow will continues to be a concern, so motorists are advised to avoid these areas and only travel if necessary."
