Did you know?
MnDOT is responsible for approximately 31,000 lane miles of roadway in the state, 3,909 of which are in the Twin Cities Metro Area.
Snow and Ice Control
MnDOT uses three techniques to inhibit ice formation and improve the roadway surface for plowing. They include:
- Anti-icing prevents the formation of frost and bonding between snow and ice and pavement.
- Anti-icing chemicals are primarily liquids applied before or early in a snowfall.
- Pre-wetting adds brine or other commercial chemical solutions to the salt and sand mixture. This causes the mixture to stick to the road instead of blowing off to the shoulder.
- De-icing uses chemical or mechanical means to break the bond that has formed between ice and the pavement.
