BIG SUR >> Emergency repairs to Highway 1 near the Rocky Creek Bridge, 12 miles south of Carmel, continue and will include extended night closures in the coming days, according to Caltrans.

There will be full overnight closures of Highway 1 at Rocky Creek on Sunday and Monday from 9 p.m.-6 a.m.

On Tuesday, there will be a full overnight closure from 10 p.m.-6 a.m. Daytime travelers on this stretch of the roadway can expect intermittent delays of up to 20 minutes as crews bring equipment on site for continued construction activities.

A slip-out occurred just south of Rocky Creek Bridge on Highway 1 — post mile 60 — on March 30 resulting in the undermining of the southbound lane. Emergency stabilization measures by Caltrans crews have been achieved and one-way, 24-7, signalized traffic control established to allow traffic to flow freely south to businesses in Big Sur.

The emergency project continues with the construction of a viaduct to support the roadway and repairs to a concrete seawall at the base of the cliff.

Crews have made substantial progress in a construction phase involving the drilling and casting of reinforced concrete columns to support the weight of the viaduct structure.

Due to the need for a large crane and other heavy equipment to span the roadway during upcoming construction activities, travelers will encounter full overnight closures in addition to intermittent daytime closures, says Caltrans.

The overnight closure schedule is weather dependent and updates will be provided as needed if wind speeds exceed thresholds for crane operations.

Once construction of the southbound section of the Rocky Creek viaduct is complete, travel will be directed onto this southbound section and work will begin on construction of the northbound portion of the viaduct.

The estimate for completion of the Rocky Creek viaduct is summer 2025 and is dependent on conditions encountered during construction.

The contractor for this project is Gordon N. Ball, Inc. of Alamo. The estimated price tag for the repair work at the Rocky Creek slip-out is $21 million.

Highway 1 remains closed 40 miles south of Carmel due to the Regent’s Slide — post mile 27.8 — which occurred March 9 and where top-down removal of slide material by crews began on April 30.

Challenging conditions associated with the extreme slope at the site and continued slide activity has extended its reopen date, however, the vast majority of the Big Sur coast remains accessible and open.

Due to continued cracking occurring at the Regent’s Slide repair site, a portion of previously damaged roadway located on Highway 1 at Regent’s Slide will not reopen in late fall 2024, as previously estimated.
