Massive Big Sur Landslide Closes Highway 1 Indefinitely
A Big Sur landslide plunged across Highway 1 and into the Pacific Ocean, burying the iconic California coastal road for a Quarter mile under a 40-foot layer of rock and dirt, and it is still moving.
More than 1-M tons of debris tumbled down a saturated slope in an area called Mud Creek, and authorities had no estimate on when the highway might re-open.
It is the latest natural disaster to hit a California community that relies heavily on the coastal highway and tourism to survive, and it adds to a record $1-B in highway damage from one of the state’s wettest winters in decades.
The weekend slide changed the coastline below to include what now looks like a rounded skirt hem, said Susana Cruz, a spokeswoman with the California Department of Transportation.
“We haven’t been able to go up there and assess. It’s still moving,” Ms. Cruz said. “We have geologists and engineers who are going to check it out this week to see how do we pick up the pieces.”
It’s the largest mudslide she knows of in the state’s history, she said. “It’s one of a kind,” Ms. Cruz said.
One of California’s rainiest and snowiest winters on record has broken a 5-year drought, but also caused flooding and landslides in much of the state and sped up coastal erosion.
“This type of thing may become more frequent, but Big Sur has its own unique geology,” said Dan Carl, a district director for the California Coastal Commission whose area includes Big Sur. “A lot of Big Sur is moving; you just don’t see it.”
Even before the weekend slide, storms across California have caused just over $1 billion in highway damage to more than 400 sites during the fiscal year that ends in June, Mark Dinger, also a spokesman for the state transportation agency, said Tuesday. That compares with $660 million last year, he said.
Big Sur is one of the state’s biggest tourist draws in a normal year, attracting visitors to serene groves of redwoods, beaches and the dramatic ocean scenery along narrow, winding Highway 1.
This Winter has been particularly rough for Big Sur, state transportation spokesman Colin Jones said. Repeated landslides and floods have taken out bridges and highways, closed campgrounds, and forced some resorts to shut down temporarily or use helicopters to fly in guests and supplies.
Even before the weekend damage, the state had closed the Highway 1 along Mud Creek to repair buckled pavement and remove debris after an earlier slide. Authorities removed work crews from the area last week after realizing that saturated soil in that area was increasingly unstable, Mr. Jones said. Road crews also have stopped work at another damaged stretch of Highway 1 in the area, for the same reason.
Last year, a wildfire burned for nearly 3 months in the Los Padres National Forest and on private land, sparked by an illegal campfire. Thousands of visitors were shut out from signature state parks and the businesses that cater to those tourists.
Kirk Gafill, president of the Big Sur Chamber of Commerce and owner of the historic Nepenthe Restaurant, said the slide may prove a blessing, stabilizing land that Caltrans was working to shore up.
On the other hand, he acknowledges his theory may be wishful thinking.
“There’s no question if you live and own a business in Big Sur, you live in a very dramatic landscape and we know historically, whether it’s fire or a mudslide or a landslide from one year to the next it’s not very predictable,” said Mr. Gafill, whose restaurant is serving 2 to 3 dozen local diners a day rather than the 600 to 1,000 typical for this time of year.
Mr. Gafill said repairing damage from the this landslide is not as critical for business as replacing Pfeiffer Canyon Bridge, a span on Highway 1 that had to be demolished earlier this year after it was badly damaged by storms in in January and February. The new bridge is scheduled to open in September.
Kurt Mayer, who owns Big Sur Tap House said, “We’re all going to make it, I’m pretty sure,” he said. “Big Sur can scare some people, and those people usually come and go pretty quickly. And those who can hang, they’re still there and they’ll continue to be there.”
