Does anybody know what the difficulties are of building a road in the tundra? Will concrete just break due to the seasonal changes in temperature? Is it that it's possible but the amount of building material would enormous? I kind of expected Russians and Canadians to be the experts of building roads or train tracks in those conditions.
