It’s inevitable that parts of Highway 50 freeze over with black ice, especially since the sun doesn’t touch parts of the road for months.

Caltrans’ answer to the seasonal sneak is to “think pink” — a mixture of sand, salt and ice slicer that’s pinkish in color. The ratio changes, depending on the temperature.
