California Department of Transportation officials (Caltrans) said in a statement on Friday that a stream of debris from the hillside above the highway “overloaded the drainage infrastructure, flowed down the highway and eroded the road, resulting in the complete loss of a segment of Highway 1 “at Rat Creek, about 15 miles south of Big Sur, a mountainous stretch of the central coast of the state.
California Highway Patrol Officer John Yerace said he was in the area on Thursday at about 4 pm when he realized that “this stretch of road, specifically the southern runway, fell into the ocean.”
Caltrans teams discovered the flow of debris on Thursday and issued an emergency contract to Papich Construction in San Luis Obispo County to assist with the repair. Early Friday morning, Caltrans teams and emergency contractors arrived on the scene and found that “both lanes on the highway were destroyed”.
The damage assessment team will continue to work over the weekend, Caltrans said. It is unclear how long the repair can take and the road will remain closed in the meantime.
Officer Yerace said that upon discovering the destroyed road, he remained in place to keep drivers safe until he was released. He came back later.
“Sometime during the night, before 6:30 am this morning, we responded back to the scene with the help of Caltrans’ access and realized that the road no longer exists,” he said.
At least 25 structures in Northern California were damaged as a result of landslides and debris flow caused by a powerful river-driven atmospheric storm. Most of the impacted areas are where scars from burns from previous forest fires exist.
