CHICAGO (AP) -- Chicago officials are detouring buses off icy Lake Shore Drive, the iconic road running along Lake Michigan, in an effort to prevent a repeat of last year's "snowmageddon."

Hundreds of cars got trapped on the thoroughfare last February when 20 inches of snow fell in the city.

The National Weather Service says this storm is expected to drop 8 inches by Friday evening.

Transit spokesman Brian Steele says icy ramps and drifting snow led to the decision to move buses away from the lakefront and onto roads with less wind and slower traffic. He says no significant problems have developed yet but officials are being cautious.

The Chicago Department of Aviation says more than 700 flights have been cancelled at Chicago's airports, the bulk of them at O'Hare International Airport.
