The most dangerous part of the road, (avalanches and rock-fall) is the part that lies within the the Park boundaries. Caltrans is a partner in the road maintenance for the entire distance. I can pretty guarantee that the NPS lacks the capability of opening the pass if Caltrans is not on-board. The NPS has snow removal equipment, but they work with Caltrans on the road. So, whatever is going on with the NPS has very little to do with the actual condition of the road at the moment.
