California's iconic Highway 1 in Big Sur is back open again after a wild three-year closure from multiple landslides. Now, folks can drive the entire coastal stretch between Carmel and Cambria for the first time since 2023.

The long closure hit local businesses and residents hard, especially those who rely on tourist traffic along this dramatic coastline. Regent's Slide, which hit on February 9, 2024, overlapped with Paul's Slide six miles south, so the area lost through access for a long time. Caltrans crews hustled seven days a week and used some pretty advanced engineering tricks to finish repairs way ahead of schedule.

Travelers can finally enjoy that classic, uninterrupted drive along one of the world's most beautiful coastal routes. The reopening reconnects the Bay Area and Southern California via the Big Sur coast, and gives access back to the region's state parks, restaurants, and attractions—many of which really struggled during the closure.

Highway 1 in Big Sur is Back Open After 3-Year Closure: What Travelers Need to Know

The Full Reopening of Highway 1 in Big Sur

Highway 1 through Big Sur opened again at noon on January 14, 2026, giving back full access along the coastal route between Carmel and Cambria for the first time in nearly three years. Crews beat the March 30 target date by almost three months, so communities and travelers got a much-needed boost along one of California’s most traveled scenic corridors.

Timeline of the Closure and Reopening

The closure started on January 14, 2023 when Paul's Slide blocked the road six miles south of where Regent's Slide would later hit. Paul's Slide kept the highway closed until June 23, 2024.

Regent's Slide struck on February 9, 2024, while crews were still fixing Paul's Slide, so closures overlapped and disruption dragged on for locals and visitors alike.

The section at Regent's Slide finally reopened on January 14, 2026. For the first time in almost three years, drivers could cruise uninterrupted along the Big Sur coast between Carmel and Cambria.

Key Areas Impacted: Regent's Slide and Rocky Creek Bridge

Regent's Slide turned into the main obstacle blocking Highway 1 through Big Sur. This landslide forced crews to do major slope stabilization work on some of the toughest terrain in California.

Caltrans hammered in over 4,600 steel bars, some as long as 60 feet, in a tight 10-by-10-foot grid to hold the hillside together. Crews cleared out about 6,000 cubic yards of mud and debris after winter storms hit, just before the reopening.

The U.S. Geological Survey says 75 miles of the Big Sur coastline are among the most landslide-prone in the western U.S.—they've mapped over 1,500 slides here. That kind of instability makes keeping Highway 1 open a never-ending challenge.

Early Reopening Ahead of Schedule

Caltrans finished repairs at Regent's Slide nearly 90 days early. Crews worked seven days a week whenever the weather let them speed up the timeline.

The project used remote-controlled bulldozers and excavators that Caterpillar Inc. helped develop. Spider excavators crawled across slopes so steep that regular equipment would've been useless.

Crews flew drones daily, did ground surveys, and monitored below the surface for slope movement. This real-time data kept everyone safer and let the team keep working, even with shifting ground and rough weather threatening to slow things down.

Causes of the Highway 1 Closure

Highway 1 through Big Sur closed several times over three years because landslides wrecked the road. Unstable geology mixed with heavy storms made life tough for repair crews.

Series of Landslides and Roadway Collapse

Regent's Slide hit on February 9, 2024, blocking a major stretch of the coast. This new slide overlapped with Paul's Slide, six miles south, which had already closed the highway from January 14, 2023, to June 23, 2024.

The U.S. Geological Survey counted 75 miles of the Big Sur coastline as some of the most landslide-prone in the West, with over 1,500 mapped slides. The unstable slopes here are notorious.

Because both slides happened around the same time, a 90-mile stretch of Highway 1 stayed closed for ages. That’s the longest shutdown in the road’s history.

Impact of Winter Storms

Winter storms dumped heavy rain, soaking the already sketchy slopes along Big Sur. Right before the highway reopened, Caltrans hauled out about 6,000 cubic yards of mud and debris from the Regent's Slide site.

That’s enough dirt to fill 240 dump trucks. More storms battered the Big Sur North Coast during repairs, making things even trickier for the crews.

Seasonal storms kept threatening both the repair work and crew safety. With so much rain on steep ground, the site was always at risk for more slides while construction was underway.

Engineering Solutions and Steel Reinforcements

Repair crews drove in more than 4,600 steel bars, up to 60 feet long, on the slopes at Regent’s Slide. They drilled and grouted these bars in a 10-by-10-foot grid to tie the hillside together and lower the risk of future slides.

Caltrans brought in remote-controlled bulldozers and excavators, working with Caterpillar Inc. The remote gear let them keep digging even when the ground was unstable, with operators safely out of harm’s way.

Spider excavators crawled across slopes too steep for regular machines. Drones, ground surveys, and subsurface monitors tracked every shift in the hillside, so crews could keep working safely during this high-stakes emergency job.

Travel Opportunities and the Reopened California Coast

The Highway 1 reopening through Big Sur opens up 90 miles of coastline between Carmel and Cambria, reconnecting travelers with state parks, hiking trails, and those classic ocean viewpoints. Now, you can actually plan a full coastal road trip and reach attractions that were cut off for years.

Panoramic Hiking Trails and Scenic Attractions

The Big Sur coast is packed with trails leading to viewpoints and redwood forests. McWay Falls Trail at Julia Pfeiffer Burns State Park brings you to an 80-foot waterfall that drops right onto the sand. Pfeiffer Beach, with its purple sand and rock arches, is a favorite for photos.

Andrew Molera State Park has over eight miles of trails through meadows and along the bluffs. The beach trail runs two miles from the parking lot to the coast. Point Lobos State Natural Reserve, just outside Carmel, offers six miles of coastal trails where you might spot sea lions or migrating whales if you’re lucky.

Garrapata State Park's Soberanes Canyon Trail climbs through redwoods and then up to ridge-top views. The park’s coastal access points lead to beaches and tide pools on two miles of shoreline.

Travel Between Carmel and Cambria

The reopened highway lets you drive 90 uninterrupted miles of coastline. Without stops, it takes about three to four hours, though most people pull over for parks and viewpoints along the way.

Nepenthe restaurant sits 808 feet above the ocean, with killer views from the terrace. The Henry Miller Memorial Library is a quirky spot for books, art, and live performances. Bixby Creek Bridge—built in 1932—spans 714 feet and towers 280 feet above the canyon floor.

You’ll find campgrounds in state parks, boutique hotels, and vacation rentals along the route. Booking ahead is smart, especially between May and October. Cell service is pretty spotty in some stretches, so don’t count on full bars the whole way.

Visitor Guidelines and Safety Post-Reopening

Winter storms sometimes shut down sections of Highway 1 while crews clear debris. Before you head out, it's smart to check road conditions—especially between November and March, when heavy rain can trigger landslides.

The U.S. Geological Survey actually calls this 75-mile stretch one of the most landslide-prone spots in the western U.S. To help with that, Caltrans put in more than 4,600 steel bars—some reaching 60 feet down—at Regent's Slide, hoping to keep the slopes in place.

Drivers need to stay alert; the highway has narrow shoulders, not many turnouts, and those drop-offs can look pretty intimidating. Only park in marked areas. State parks charge a day-use fee per vehicle, usually between $10 and $15.
