CHICAGO — A wintry mix Friday caused messy, hazardous travel conditions in some parts of the Chicago area.

Scattered bursts of snowfall created slippery and icy conditions on the roads in Northwest Indiana, the south side of Chicago and the southern suburbs.

Multiple crashes were reported on area roads, including on eastbound Interstate 94 near Lake Station due to a crash involving an overturned Amazon truck. Interstate 65 also had closures in both directions near US231 due to rolled over semi trucks.

A crash involving vehicle and a school bus was also reported at Kedzie and 143rd.

Officials advised driving with extreme caution and allowing extra time for travel.
