This portion of Highway 1 will reopen with the use of a 24/7 signalized traffic control. This temporary signal will provide unrestricted public access with one-way alternating traffic in both the north and southbound directions.

On March 30, a rockslide below Highway 1 south of the Rocky Creek Bridge left the southbound lane partially undermined and impassable. Approximately 6 feet of the pavement and a portion of an unreinforced masonry retaining wall that supported the highway fell to the ocean about 170 feet below the road.

In order to stabilize the remaining southbound lane and preserve the northbound lane, crews drilled, installed and grouted 40 vertical and 75 sub-horizontal steel elements into the slope. The steel elements, or rock dowels, are covered by an application of shotcrete to protect the exposed rock slope. This work required Caltrans to close the roadway in both directions at Rocky Creek, aside from twice-daily convoys through the slip-out area.

Now that Caltrans has stabilized the southbound lane and preserved the northbound lane, the site will continue to be monitored and visually inspected. A project to construct a permanent repair to the highway at this location is currently in the design phase, with an estimated completion date of spring 2025.
