There are no connecting roads in Nunavut.
The NWT has highways in the south, and a winter road that you can drive beyond Tulita, but other than that, you’ve got to fly.
Oh, and there is a road between Inuvik and Tuk in the winter as well, which you can use to connect to a winter road that will take you to Whitehorse, and from there points distant.
I would never live in the high arctic. Populated or not, those little settlements are desolate, depressing places. Yellowknife was far enough north for me. There is a feeling of desperation that sets in during the freeze and thaw of the Mackenzie, knowing that you can’t drive out, not even to Hay River.
