Most of the route is through extremely rugged mountainous terrain, not tundra, and developing a roadbed that can survive -70 F winters is a lot more involved than "piling dirt into a shape"
I traveled it before was paved, and it was, and is, a true engineering marvel.
Yes, I both unravelled my vast illiteracy on road engineering in general and understated a bit on purpose. My point was that there is not much existing infrastructure to take into account up there. Your point taken though.
