Most area highways, roads and city streets remain slick and hazardous today.
Road salt is not as effective on icy roadways in these temperatures.
INDOT is using other methods to melt ice and gain traction on road surfaces, such as chemical anti-icing agents and sand.
However, the frigid weather is hindering those efforts as well.
