Minnesota Cities Transitioning from Salt to Spraying Brine

by

(ST.PAUL,MINN)UTVS- Minnesota cities are beginning to transition from using salt on the roads to spraying brine in order to keep the roads ice-free this winter. Spraying this saltwater 24 to 48 hours before a storm can remove the amount of salt on the road. Spraying brine also reduces the amount of salt pollution in lakes and rivers.

Spraying brine creates a barrier aby applying a small coat of salt on the roads which prevents any new precipitation from sticking to the road. The Minnesota Department of Transportation has equipped brine sprayers to 840 snowplows.
