Highway Closure Update

HIGHWAY 1 UPDATE – Monday, Nov. 13*
State Route 1 in Monterey County remains closed from north of Salmon Creek, just south of the Ranger Station (PM 3) to just south of Gorda (PM 10) due to the Mud Creek slide. State Route 1 south of Salmon Creek is accessible via State Route 1 in San Luis Obispo County near Ragged Point.

REMINDER: Travelers still CANNOT access the entire length of Highway 1 from Carmel to Cambria but local businesses are open on both sides of Mud Creek.

Mud Creek (PM 8.9)
Mud Creek had a major slide on Saturday, May 20, 2017, losing over 5 million cubic yards of material. Caltrans continues with its plan to realign the existing terrain with the projected timeline to safely open to public traffic is late-summer 2018 at an estimated cost of $40 million.

Last week, the contractor continued placing rock revetment, working from the north going south and will place rock revetment across the entire toe. Roadwork continues to construct the south fill embankment. These same operations will continue this week.

There is currently no public/local access through the Mud Creek area since this remains an active, emergency construction zone.

Paul’s Slide (PM 21.6)
Paul’s Slide is still active but the 24/7 traffic signal remains in place and temporary guardrail (k-rail) in the centerline.

Pfeiffer Canyon Bridge [PCB] (PM 45.52)
Final work continues for several weeks. Roadwork at Pfeiffer Canyon Bridge consists of alternating lane closures from 7 am to 4 pm Mondays through Thursdays and 7 am to 2 pm on Fridays until work is complete. The contractor stripped the right side bridge overhang and brackets and removed the project cameras last week. This week they will begin stacking and banding material to demobilize.

  1. Kate,

    Hot damn on Rock #1…How safe are these landslides to real solid earthquake movements? Rolling Rocks… Did USGS know how large a quake would have to be triggered to get more mountain to fall? How strong an earthquake can the new Pfeiffer Bridge handle?




  2. Yes, many people felt today’s 4.7 out NE of Gonzalez. All older bridges have been retrofitted for earth quake, and I’d be very surprised is PCB wasn’t designed to withstand a big one. Re Mud Creek? That is in Mother Nature’s hands…



  3. Re-post of my previous comment on the page with the link to the 11/9/17 LA Times article:

    The pyramid rock that is now in the ocean was on top of the toe of the slide after the May 20 dump. In fact, geologists placed equipment on top of the rock to analyze the newly formed peninsula. It’s revealing to see how fast the ocean eroded away the soil under the boulder so that it now sits in the water.


  4. Yes, it has been interesting to watch the erosion. Per the LIDAR company, we lost 20 ft of shoreline a couple weeks ago.
