Aside from wooden snow fences, why doesn’t WY build snow barriers right next to I-80?

Wait lil bit. Climate change is coming.

 

Lack of funds. I've seen parts of interstates where they tried something like that, that stretch of trees on the north side of 90 just west of Mitchell SD comes to mind, it doesnt really help all that much because it sticks there when it blows off every where else in small snow squalls.

 

Because the engineers say what they have now is the best system.

I don't know but a guess would be if there was a barrier or wall of some type parallel on either side of the road that barrier would/could also trap the snow on the road surface.

 

just a wild guess, cuz it's been decades since i been that far west, maybe they cannot do as you ask, cuz the animals cross more so in those areas, than in the others?

 

Which is cheaper, flip switch to turn on sign "Road Closed", or build hundreds of miles of more snow fences that don't help much?????

 

those migration bridges can't be too cheap. i'd think that endangered species would be taken into consideration for such a bridge over, an over population of useless deer, elk, etc.
