The fire apparently began when a car struck a power pole on Mountain Boulevard near Keller Avenue, causing power lines to fall and spark.
The fire drew a quick and forceful response from firefighters who were concerned about the hilly terrain and dense vegitation. Twenty people in nearby homes were evacuated.
Oakland Fire Department Batt. Chief Melinda Drayton said the more than 100 firefighters on scene were helped by the location of the grass and tree fire. She said the streets acted as natural fire breaks, helpeing the firefighters from keeping the flames from spreading. No injuries were reported and no homes were damaged.
The fire was contained shortly after 3 p.m. Less than two acres were burned.
A PG&E spokesperson says 6,700 customers in the area lost power because of the downed line. Crews are working on the outage and the downed lines but there is no estimated time for when power will be restored. Shortly before 6 p.m., about 150 customers remained without power.
There is no word on what caused the crash, but a good Samaritan who helped the driver out of the car says the woman was clutching her chest.
I-580 to close for power line repair
All lanes of I-580 in Oakland will close for 30-60 minutes after the Friday evening commute so PG&E can repair the power lines damaged in the crash.
The closure is expected to begin at 9 p.m. Westbound traffic will be diverted at Golf Links Road and eastbound traffic will be diverted at Seminary Avenue. Highway 13 will be diverted at Carson Street.
The CHP is asking motorists to avoid the area.
