Caltrans began lane closures on the Pacific Coast Highway and Topanga Canyon Boulevard on Sunday, August 23, 2026, to start recovery and repair work after damage from the Palisades Fire. The closures affect the stretch of PCH between Temescal Canyon Road in Pacific Palisades and Carbon Beach Terrace in Malibu, as well as the segment of Topanga Canyon Boulevard that runs from the highway to Grand View Drive.
The agency announced that the closures are necessary to address damage sustained by the coastal highway during the recent Palisades Fire. Work crews will focus on restoring the roadway and ensuring safety for future traffic. Drivers are being directed to use alternate routes while the repairs are underway.
The Pacific Coast Highway segment impacted runs through a heavily trafficked coastal corridor that serves both local residents and tourists traveling between Pacific Palisades and Malibu. The Topanga Canyon Boulevard portion provides a key link between the highway and inland neighborhoods, and its closure may affect commuters heading toward the San Fernando Valley.
Caltrans has not released a specific timeline for the completion of the repairs, but the agency indicated that the work will proceed as quickly as conditions allow. Motorists are advised to monitor traffic updates and follow posted signage at the closure points.
The Palisades Fire, which burned through sections of the coastal area earlier this year, left significant damage to vegetation, infrastructure, and the roadway itself. The current lane closures are part of a broader effort to restore the affected transportation network and prevent further hazards.
Travelers planning routes through the Pacific Palisades and Malibu region are encouraged to check for real‑time traffic information and consider alternative paths while the repair work continues.
