Highway 1 has ‘significant instability,’ Caltrans says, as another rock slide is reported

Highway 1 along Big Sur remained closed Monday after Caltrans reported a new rock slide just south of Mill Creek in Monterey County the day earlier.

Locations along the highway show “significant instability” after the recent run of rainfall, Caltrans said in a news release Sunday.

At Paul’s Slide in Big Sur, sections of the catchment area’s concrete barriers, used to prevent further slides, had moved into the center of the roadway due to “recent activity,” the agency said.

“In addition, there are multiple locations within the closure area which are exhibiting activity and, in some cases, distributing material across the roadway or undermining the road,” Caltrans said.

The additional slide comes as Highway 1 has experienced off and on closures since December.

With weather expected to clear up sometime Wednesday, Caltrans and additional contracted crews will help clear the road.

Crews that live within the closure area are “conserving supplies as a result of this extended period of storms,” the release said.
