This is what happens when a mountain slumps into a road... the asphalt is heaved into the air. This slump happened after the torrential rains two years ago. It is along old Ridge Route, the original precursor to Highway 5 over the Grapevine. Ridge Route was severely damaged during these rains and is now closed to the public. The road is expected to be repaired by next summer barring further damage. But signs point to an El Nino winter, which could mean more floods.
