After restoring power to thousands of customers along the Peninsula following an outage this evening, PG&E crews are working to restore another outage in San Francisco that briefly knocked out lights on the Bay Bridge, a utility spokesman said.

Shortly before 6 p.m., an outage caused by a downed transmission line was reported near San Bruno and was affecting about 10,000 customers, PG&E spokesman J.D. Guidi said.
Power was restored to all customers in the area by 6:55 p.m., Guidi said.

Another outage was reported at about 6:20 p.m. in San Francisco’s South of Market District, he said.

A smoking manhole was reported at the intersection of Second and Harrison streets and originally knocked out power to more than 1,300 customers, according to Guidi.

The outage briefly knocked out lights on the Bay Bridge, Guidi said.

The lack of lights did not affect traffic on the bridge or marine vessels in the water below, but San Francisco International Airport and Oakland International Airport officials were notified that the warning lights on the bridge were out, California Highway Patrol Officer Ralph Caggiano said.
All lights on the bridge were restored by 8:45 p.m., Caggiano said.

About 340 PG&E customers in San Francisco remained without power as of 8:45 p.m., but all customers in the area should have their power restored before midnight, according to Guidi.

PG&E investigators are looking into what caused the smoking manhole, he said.
