This winter MN-Dot is trying out four new types of equipment aiming to more efficiently remove snow and ice from the state’s roads. Maintenance research engineer Tom Peters says the basic technology of plowing doesn’t change, but they have a responsibility to seek out the best ways to get the job done.

“It is a fine balance, but if we can put one more good tool in our toolbox in treating winter maintenance, that is what we are really interested in trying to do.”

The new technology in the trial program includes a more efficient slurry spreader, an underbody scraper, a two-way plow blade, and a variation on the side wing float.
