Welp, the road was washed out again, this time at Rat Creek.
Trying to figure out how that happened. Presumably there was a culvert under the road to allow the water to pass through. Did it get clogged with debris? Fortunately, no one was hurt, but who knows how long Big Sur will be cut off from the south?
Yup, as I suspected, the debris flow clogged the culvert.
As I note in comments, this was one of many washouts waiting to happen.
