Roads are built
through "nowhere" all the time .. to join one city to another several thousand miles away with no other "civilisation" between.
To join a port to an inland mine site.
Once you have a road where once there was no road and no easy access to the land within then people can follow.
> But nobody builds a road to nowhere.
See: Gunbarrel Highway - a road system from a launch point out into "nowhere" in order to retrieve test missiles.
