A 25-meter section of the Pacific Coast Highway slid into the Pacific about 30 km south of Big Sur this week:
Caltrans spokesperson Jim Shivers said the damage to the highway is called a slip out. "It's where we lose a part of the highway and now we're facing a project to clean and repair that stretch," Shivers said. "This is the only location we're aware of where this happened in the storm. Our maintenance team is patrolling the highway now to look for other damage."
The closure is in Rat Creek between MPM 40 and the San Luis Obispo county line, the California Highway Patrol said.
A common phenomenon called an "atmospheric river" delivered half a meter of rainfall to the region last week. CA-1 has a history of sliding into the ocean; for example, the area just south of Pacifica, Calif., known as "Devil's Slide" collapsed so frequently that that Caltrans bored two 1200-meter tunnels through solid rock from 2005 to 2013 to keep the road open.
