road is closed to public access sunrise to sunset which should be added here: see conditional access time section https://wiki.openstreetmap.org/wiki/Key:access, and road also allows pedestrian, bike, cross-country skiing, and snow-shoeing access which could be added as well. road is not plowed during winter so additional tag for winter service should be added: https://wiki.openstreetmap.org/wiki/Key:winter_service.
