SAN FRANCISCO — Authorities urged motorists to avoid California’s Highway 1 along the central coast after a section of the scenic route collapsed during an Easter weekend storm, forcing closures and stranding motorists near Big Sur, authorities said.

The collapse occurred amid heavy rain Saturday afternoon near Rocky Creek Bridge about 17 miles south of Monterey, sending chunks of asphalt tumbling into the ocean from the southbound side of the two-lane road.

The highway was closed in both directions in the mountainous area of California’s central coast as engineers assessed the damage, said the state Department of Transportation, or Caltrans.

“We are working on a plan to get motorists evacuated from the area,” the California Highway Patrol said Saturday.
Around noon on Sunday, crews had determined that travel in the northbound lane was safe, and authorities began periodically escorting motorists around the damaged section. About 300 cars were waiting to travel northbound when officials led the first convoy through the area, the San Francisco Chronicle reported.

Some stranded motorists had slept in their cars overnight while others were sheltered at the nearby Big Sur Lodge, the newspaper said.
