HIGHWAY 1 UPDATE – Monday, Dec. 11

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, continued constructing the south fill embankment and also constructing the middle portion of the fill. These same operations will continue this week.

the contractor continued placing rock revetment, working from the north going south and will place rock revetment across the entire toe. Also, construction continues of 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.

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. Last week the contractor performed concrete finishing on the structure, prep, zinc coating and painting on girders, final grading in the canyon and underground installation for the seismic monitoring equipment. This week, the contractor will continue the painting and concrete finishing activities and begin installation of the joint seal assemblies, anticipating completion at the end of the week. Additionally, they will begin placing erosion control on the project—activities this week will require lane closures, as mentioned above.

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