The fun part of North dakota is the extremes. The record low (without wind chill) is -60 F, the record high is 122 F. That is a 182 degree spread, or 100 C spread for the rest of the world.
I often wonder how much money Northern states would save on roads if it weren’t for the extreme temperature swings.
Regularly hit highs over 100 in the summer, lows below -30 in the winter. That’s an awful lot of compression and expansion. Not to mention the abuse of heavy plows and their blades catching upheaved concrete.
It’s actually too cold for salt to be reliable. Water fully saturated with salt freezes at ~-21/-6(c/f), so if it’s predictably getting colder than that, it’s a bad idea to use salt.
Edit: They add beet juice when it’s really cold, but otherwise, it looks like they use salt :(

Should also mention the just, massive amount of salt dumped on them every year. Salt just ruins everything it touches.
Except french fries
Most meats, too.

It’s salt but it’s not sodium cloride. It’s usually calcium cloride. That’s usually good to -30/-34 F/C.
