A water main serving the Adamson House broke Wednesday in Malibu, prompting a lane closure on westbound Pacific Coast Highway.
The break was reported at 8 a.m. Wednesday and repairs got underway about 10 a.m., according to Kerjon Lee, a spokesman LA County Department of Public Works.
Crews will likely continue to work on repairs until midnight, Lee said.
"We’re currently rerouting the line," Lee said.
The far right lane westbound lane of Pacific Coast Highway was closed from Jack in the Box to the entrance of Serra Retreat.
