It's not necessarily the road that is a problem, although building it would be disruptive. People are the problem. The WA near my community has a road that allows access to a huge area. Some users exploit this access to degrade natural and cultural resources: defacing rock art, littering, driving off-trail and the like. They make a good argument for the road closure being considered. It's unfortunate because most visitors do not cause these problems. We can't realistically enforce the rules, so the choice is between allowing access on the road or not.
