Actually, the road  is impossible, there are *trees* growing where the road was. It is not navigable with any kind of vehicle, not even off-road trucks.

Prior to the trees, the road was unmaintained, dirt with rock slides and huge holes that can trap a car. That part was overgrown with plants that scraped both sides of the car.  
We had to back up in that environment, trying to not go over the cliff.
If the road exists, it is only in the legal sense.

It needs to be flagged as impassible, at a minimum.
