BISMARCK, N.D. (AP) — North Dakota’s Transportation Department says it’s altering the recipe for icy roads to cut costs.
Program manager Mike Kisse (KEE’-see) says sand is being taken out of the mix and the agency will rely solely on salt to treat highways when the weather remains just below freezing.
Kisse says same amount of salt will be applied as before on state highways. But he says taking sand out of the beds of snowplow trucks will allow them to travel five times as far.
Kisse says that will save fuel and time without losing ice-melting efficiency.

Below 15 degrees, the state will continue to use saltwater that’s blended with beet juice from sugar refiners in North Dakota and Minnesota. Kisse says that mixture is effective to about 18 below zero.
