A major gas leak near the Pacific Coast Highway in Malibu prompted a two-mile closure of PCH in both directions near Carbon Canyon Road, according to the California Highway Patrol, but it reopened by 11:33 a.m.
Thirty residents and 20 businesses were evacuated from the 22400 block of PCH, NBC Los Angeles reports. The highway was closed for about two hours.
A public works crew drove over the line and caused the break, according to the Los Angeles County Fire Department.
Firefighters responded at 9:36 a.m., Los Angeles County Fire Inspector Quvondo Johnson said.
"We were dispatched out to a high pressure gas main. It looks it initially came in that public works had ran over that," Johnson said. "We got the gas company out there to shut that gas down."
One of the buildings that firefighters looked to evacuate was vacant.
