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.
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 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.
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
One of the few advantages of dirt roads, salt doesn’t damage them
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.
It’s wonder our roads look like they were shelled once spring rolls around. Last year was particularly bad, I don’t think the roads were in decent shape until the end of the summer. At least near Minneapolis.
And then the cycle repeats
That sounds so fun!
Weeeee
That’s chilly. I might even have to wear pants instead of shorts if it were that cold.
Please, a true Scotsman would wear a kilt (commando) proudly regardless of temperature and if that means they can’t procreate due to their junk falling off from frostbite then so be it.
Well, I do own 2 kilts and I’m “fixed”, so can’t procreate anywho.
It’s a little disingenuous to compare winter in North Dakota to Miami in this manner, and to include the windchill. I don’t know the average temperature in Miami in January, but I do know that this is not “strange” for North Dakota in January.
Thought the same. It’s disappointing to see click bait from the AP but I guess that’s the new way of doing business when nobody wants to pay for news
It was only 71 today just north of Miami. We have at least a couple weeks before 96°.
I’m a Michigander. We don’t get ridiculous low temps like -70 or anything but, I wish most roads would be left alone. Plow and salt main Highways and expressways but, leave everything else undone. Then we can buy vehicles that can traverse the snow like sleds or good 4x4 rigs.
This would keep our roads nicer and would keep our cars from rotting out
That’s not really feasible. School buses is one obvious reason (among many others).
Come on…we could have school sled dog “busses”!
Or snow machines.
Kids can take their parents’ sled to school.
If you have no traction it doesn’t matter how many wheels have power to them your still gonna slip.
Amoung the tons of other issues with just not plowing some roads. Comment reeks of brainrot.
If your losing traction you don’t have a good 4x4 rig.
It doesn’t matter how good the rig is if all four wheels are on ice lol.
That’s where studs come in. Been there done that. Just takes more prep
Also this is why I’m only advocating for back roads and rural roads to not be plowed. And to have people prepare themselves for that kindve environment instead of relying on us as a society to try and stop the weather from doing what it does.
And if it’s to slick take the sled. Or snow machine
Sleds we’re mentioned for a reason. Make it the job of the individual to decide if leaving here is worth the work or not
Reduce car dependency, plow side roads first because main roads clear themselves.
