DENVER -- The Colorado Department of Transportation is testing new ways to keep roads safe during winter storms.

CDOT crews will use salt brine to prevent ice from forming on roads during storms.

The brine is used when temperatures begin to freeze at least eight hours before a storm.

"Instead of waiting for the snow to accumulate and pushing it off, brining allows us to use our time better," said Mike O'Neill with CDOT.

White salt lines will be seen on the roads but when the snow starts to fall, crews will switch to magnesium chloride. O'Neill said using both will save time and money.

Salt brine costs about 40 cents a gallon, while magnesium chloride costs about $1 a gallon.

CDOT said it will focus on the major highways for the brine, but it hopes the time that will be saved will allow it to focus on side roads as well.
