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.

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 with north fill and the mud creek drainage, installing a 24-inch culvert at the southern end of the job. This week, the contractor continues working on the north fill at the northern flank of the slide, enhancing the revetment across the toe of the slide to increase the height of the rock, trucking, moving, and placing rock, and installation and fabrication of drainage features like welded HDPE pipe, concrete drainage inlets, etc. From a monitoring perspective, we continue to work with Surveys to remotely read prism positions on the landslide, manually measure movement using extensometers and distances between known positions, and making frequent visual observations.

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

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