The Idaho Transportation Department says the unusually cold temperatures are creating some challenges in keeping roads safe. Crews are using sand on the roadways instead of salt, as salt is less effective in extremely cold temperatures.
The problem with sand though is that it is easily blown off the roadway by traffic. State crews are working around the clock, seven days a week to keep the roads sanded. They cover a road section at least four times per day and will do so more often during storms.
So take it easy out there and remember that the roads may be even more slick than normal in the winter.
