Excerpts from the Chicago Tribune:

Lake-effect snow that is expected to hang around Chicago until the middle of the afternoon is causing slippery conditions on some area roadways close to Lake Michigan, leading to multiple accidents like the one that fouled up traffic on the Kennedy Expressway Sunday morning and afternoon.

Police said the snow conditions were responsible for the chain-reaction crash as there are no shoulders on the express lanes. The expressway was reopened at about 11 a.m., police said.
