Highway 1 South of Big Sur Reopens After Fix to Section That Collapsed in Winter Storms

A section of California's scenic Highway 1 that collapsed during a winter storm reopened to traffic on Friday.

Gov. Gavin Newsom and work crews stood on the freshly paved and marked roadway to celebrate the reopening of the main artery south of Big Sur, which attracts millions of tourists each year.

"There are few, if any, more iconic routes than Highway 1 – not just in California but anywhere in the world. What this road means to the local economy, to the people of this region and to all Californians is invaluable," Newsom said.

"As we rebuild, we do so with the knowledge that the conditions that washed out this section of roadway will become more common in the future. We must fortify our infrastructure with climate resiliency in mind."

The highway has been closed since Jan. 28, when heavy rain unleashed torrents of mud and debris left over from a wildfire, washing a 150-foot chunk of roadway down into the sea.

Storms in 2017 caused slides that closed off Big Sur for more than a year.

This time, crews began to fill the canyon below with compacted dirt in early March. They worked nearly 12-hour shifts, seven days a week, and were able to restore the roadway nearly two months ahead of schedule, aided by dry weather and increasingly longer days, the California Department of Transportation said.

After reopening, crews will replace the main drainage system above the fixed roadway to help withstand future debris flows, rising sea levels and coastal erosion, Caltrans said.

They will also work on landscaping and installing guardrails throughout the early summer.

The work was estimated to cost $11.5 million, the agency said.
