Just standing out along the side of road for a few minutes on Route 157 in Collinsville was enough for me. The blowing snow in my face whipped across the road as passing cars were packing it onto the surface.
Highway officials are also worried about treated roads freezing over again as we reach a low near 5 degrees and fall into the deep freeze for the next few days.
Crews for MODOT and IDOT will be out all night, but drivers should not assume conditions will be normal in the morning. Trouble spots are expected to be on the highway ramps and on secondary roads.
