You can't get rid of the road. You can ban personal vehicles from it, but emergency response including fire and EMS need to be able to travel up and down the road. As BenedictGomez mentions too, unless public transit ran 24/7, staff and others will need to be able to get to/from in the off hours. Also, what about mountaineers and backcountry skiers who want to park at 4am to start a long, technical uphill?
Again, banning personal cars and forcing people to use some public transit solution is one option. Tolls or 100% paid parking (with some proceeds going towards improving public transit) is another solution where vehicles are allowed, but the increased costs mean less people end up driving. I will say that the increased costs may impact locals more than tourists. If I'm a tourist, who cares about $20 to park when I've already spent way, way more than that to fly there, rent a hotel, eat meals, etc. If paid parking/tolls ends up costing quite a bit, you might also see more demand for the on-mountain lodging options, which, given the inability to add supply, will drive up prices for the Cliff Lodge, Goldminer's Daughter, and so on.
