"fences" along I-80 WY

We just returned from a trip to Laramie, Wyoming via Denver Intl. DH and I noticed these oddly placed "fences" at various places along the interstate. My guess is that they accumulate snow in the winter and keep it off the roadway? Another theory was to break up wind for the cars/semis?

So what do they actually do?! I kept forgetting to ask locals!

These are snow fences to prevent ground blizzards which happen in flat, windy places. Even if the snow isn't falling from the sky, the wind-whipped snow can create very dangerous conditions on roadways - zero visibility. These fences help prevent that. Interesting you should notice that - very observant of you!

I just thought they seemed quite odd and out of place since they weren't connected or keeping anything in or out!

I kept asking DH why would they build all these fences randomly like this?!

We aren't used to flat terrain like that so they really stood out! Our experiences are with trees along most of our highways (Pa, NC, SC, Ga). However, I am kind of surprised they don't come in handy near the Lake between Erie and Buffalo since it is lot flatter and winter weather is harsher up that way!

When you're driving along those highways in the winter on windy days (not necessary during snowstorm, as the snow is blown from the snow-covered fields), it's pretty apparent which sections of the roadway are protected by the snow fences and which sections are not.
