Have a look at this, for instance:(0) Not as elegant as the Japanese operation, but the photo probably predates GPS, to the Norwegian snow plow crews credit. I'd feel very small traversing down that road. Doubly so if I suddenly met a heavy truck, a bus or anything larger than a bicycle, really...
I just stumbled upon a couple of nice photos of the current weather conditions at Haukeli, one of the passes currently closed. Just click the photo for the next one. (1)
