HIGHWAY 1 UPDATE – Monday, May 21

HIGHWAY 1 UPDATE – Monday, May 21

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. The Department has announced a new target of mid-September to get lanes re-opened to traffic. Caltrans will continuously evaluate the opening date as work progresses so we anticipate providing an update in July. It’s expected that even after the highway is re-open, intermittent lane closures and roadwork may continue. The updated current cost is at $54 million.

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

This week: Work continues with the north fill, north cut and north berm with hilfiker retaining wall.


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. A full, daytime closure took place at Paul’s last Monday, May 14, 2018 to make repairs to the Hermitage Tieback Wall. (See attached photo).


Final items continue taking place. Metal Beam Guardrail (MBGR) end treatment work at Castro Canyon (PM 43.12) and slope work at the Coastlands (PM 44.41) continues taking place. However, no work is scheduled for this week north of Lucia.

Caltrans reminds motorists to move over and slow down when driving through highway work zones.

The next update will be on Tuesday, May 29.

  1. I assume you can travel from Monterey or Carmel south to Nepenthe? I’ve been reading several notes that contradict this, but looking at the map of closure, it seems that Nepenthe cab be visited via car, as the is open again. If not, what is the best way to get to Nepenthe from the North?

    • Yes, you can visit Nepenthe from Monterey/Carmel. You can drive 63 miles south of Carmel on Highway 1 and 53 miles south of Carmel is a detour that will take you to Highway 101 if you want to drive “through” Big Sur.
      Enjoy Nepenthe!
