(WTVR) - A cheese plant in Wisconsin is partnering with the area highway department to make a brine they said keeps snowy roads from getting too slick.

"The cheese whey itself froze at a lower point than regular salt brine," said highway manager Moe Norby.

The high sodium makes the brine a perfect replacement for the conventional magnesium chloride, the chemical most often used by highway departments.

Highway officials also said they are saving a lot of money by using the cheese instead.
