A wind-driven brush fire that grew to 1,236 acres, forcing road closures and mandatory evacuations in Solimar Beach near Ventura, was ignited by a downed power line, fire officials said Saturday.
Fire officials said the blaze was 70 percent contained, and evacuation orders would be lifted.
No structures were lost.
More than 600 firefighters from multiple agencies were assisting in the blaze, which erupted Friday night, according to the Ventura County Fire Department.
The California Highway Patrol shut down a stretch of the Pacific Coast Highway, the northbound 101 Freeway at State Route 33, the southbound 101 Freeway at Bates Road, and the Union Pacific Railroads.
Both directions of the 101 Freeway as well as Pacific Coast Highway were reopened Saturday afternoon, according to the Ventura County Fire Department.
Fire crews faced strong northwest winds of up to 25 mph and said the fire posed a threat to oil, gas, power and rail infrastructure. Officials said they anticipate the firefight will last up to three days.
