Check this stretch of road that connect the Japanese municipalities of Tateyama and Omachi called the Tateyama Kurobe Alpine Route... Instead of a few feet of snow, they got a few meters...!!
-see more photos and a video of how they clear a completely buried mountain road below:
How on Earth do they manage to clear that road, and get the sidewalls so freaking straight? As you'll see in the video-which seems it was produced in the '80s-they use a combination of snowblowing vehicles and a backhoe to "sculpt" the walls.
