Getting rid of it will depend on what the weather does. If we get a thaw they'll scrape it bit by bit back into the traffic lanes and let it melt. If it keeps snowing and cold and gets too large they'll have to start loading it into trucks, an expensive proposition.
I feel for my fellows in the Portland area, this is winter in NE OR and we have to deal with it every year unless it is an exceptional year and those are very bad for us. This is what keeps our forests alive through our summer and fall. Yes, it means owning snow tires, owning vehicles that can cope, and higher heat bills. The roads are a mess and if you don't know what you're doing you're going to have problems. Schools, road departments, and just about everything costs more because this is how this place is. It is a real good idea to keep in mind that this country can kill you and help may depend on you, yourself.
