    Should also mention the just, massive amount of salt dumped on them every year. Salt just ruins everything it touches.

      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 :(

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

          Interesting, I haven’t found anything to support that (but it’s weirdly difficult to research, so it could just be DDG not understanding what I’m looking for), do you have a source for that?

          I found halite (unrefined sodium chloride) as the primary type of rock salt in the US. Wikipedia lists beer, molasses, and beet juice as possible alternatives for roads or glycol and sugar for airlines.

          The EPA does list CaCl as an option, but notes that it’s both better for the environment and more expensive, so it’s reserved for vulnerable areas. I found this which doesn’t specify which they use, but gives an effective temperature range that sounds like NaCl for North Dakota.

      I lived in North Dakota for almost 5 years, they dont use salt. Just a sand/dirt mix. Things get really nasty in the spring/early summer when it all starts melting. They were trying out a weird chemical mix when we moved away, i want to say some glycol something or other? It was actually pretty slimy but way better than ice.

        I lived there for 11 years… don’t remember much, except when the blizzard turned the road into a skating rink, and the wind (which you could actually see) pushed me across the highway into a ditch. Every morning for weeks, I had to plow through the snow-drifts every 100 feet of the gravel road to get to that highway.

        Oh yeah, and that big buffalo statue, and that world’s tallest tower.

        But I did get a lot of Sci-fi read during the slow season. Those Minot airmen sentenced to the AFB did leave behind a lot of good SF books.

      Many places have switched to a brine which uses a waste byproduct from cheese production. This greatly reduces how much salt is thrown onto the roads and also makes use of literal waste

      Edit: looks like there’s a few different mixtures but here’s the cheese brine from Wisconsin

      When it gets that cold salt is useless, so thankfully we see much less of it throughout the winter. Sand is used instead. -20C and salt sort of stops working.
