HIGHWAY 1 UPDATE – Monday, April 9

HIGHWAY 1 UPDATE – Monday, April 9
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.

This week: The same ongoing operations continue: building up the north fill, working on the 63 inch drainage system, working on the retaining wall and excavating material below the new alignment to finished grade.

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 was cleaned up last week from debris and slide material. It is still active but the 24/7 traffic signal remains in place and temporary guardrail (k-rail) in the centerline.

1.) Final work is complete and inspection/completion approval is expected by next week—photo shows completion of installation of flange protection devices.


Final items continue taking place for the next two months. Metal Beam Guardrail (MBGR) end treatment work at Castro Canyon (PM 43.12) and slope work along project limits is scheduled to take place in early Spring, weather permitting.

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

The next update will be on Monday, April 16 ☺
