No major problems on Chicago roads amid snow

CHICAGO (AP) — Warnings about a big snowstorm in Chicago may have paid off.

Illinois Department of Transportation spokesman Mike Claffey says there are no reports of any major traffic accidents on Chicago expressways. He also says traffic volumes have been lighter than normal Tuesday afternoon. That's a sign that many people took public transportation instead of cars.

The storm had dumped 6 inches of snow at Chicago's O'Hare International Airport by Tuesday afternoon.

Chicago has not had a big snowstorm since a 2011 blizzard dumped 20 inches, shutting down Lake Shore Drive.

Tuesday's storm was part of a system that started in Montana, hit the Dakotas and Minnesota on Monday, then barreled through Wisconsin and Illinois on its way to Washington, D.C.
