HIGHWAY 1 UPDATE – Monday, Jan. 29, 2018

Photos 1 and 2 of Mud Creek (PM 8.9); photos 3 and 4 of Paul’s Slide (PM 21.6); photos 5 and 6 of Pfeiffer Canyon Bridge “PCB” area (PM 45.52)—all photos taken last Friday, Jan. 26.

HIGHWAY 1 UPDATE – Monday, Jan. 29, 2018

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 completed the 24” down drain on the culvert at the southern end of the project. This week, they continue to work on rock placement and construction of the north fill slopes.

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. 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. Last week fog sealing and other final items took place. This week, we will finish a couple of items today and tomorrow, Tuesday. We will haul the project trailer off on Wednesday and grade the lot (turnout) where the trailer and yard were. We will be doing permanent seeding Thursday and Friday under lane closures. The majority of work is expected to be complete at the end of this week, with only a few final items remaining, weather permitting.


This week: Paving and shoulder backing from one mile north to one mile south of Cow Cliffs (PM 28.35).

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

The next update will be on Monday, Feb. 5 ☺
