Several inches of snow in the Tri-State may take a while to melt.
Forecasters say temperatures will stay below freezing until Saturday, and could dip below zero Wednesday night.
INDOT spokesman Will Wingfield says the agency’s yellow snow plows take 2-to-3 hours to complete a route on state and federal highways, and salt is applied to help melt the snow and ice. But he says with temperatures well below freezing, it takes longer for the salt to work.
Wingfield warns of melt-water refreezing, which can create black ice on roadways. He urges drivers to take it slow and allow extra time to reach your destination.
