EL CAJON (CNS) - Utility crews finished restoring power Friday to an East County neighborhood where some people were without electrical service for nearly 24 hours after a half-dozen power poles toppled onto a busy road for reasons that remain unclear.
San Diego Gas & Electric personnel completed repairs to the transmission equipment along Mollison Street in El Cajon about 4:15 p.m., bringing the last 100 or so blacked-out addresses back online, SDG&E spokeswoman Amber Albrecht said.
About 2,400 homes and businesses initially lost power when the six roadside utility standards fell into the north-south street about 4:30 p.m. Thursday. About 1,000 of those customers were quickly back in service, and repair crews worked through the night and into this afternoon to return electrical service to the neighborhood, according to Albrecht.
The accident -- which resulted in no reported injuries and apparently caused no damage to structures or vehicles -- forced a long-term closure of the roadway between Main Street and Washington Avenue.
The cause of the mishap remained under investigation, but it appeared that one of the wooden poles initially became unstable somehow, fell and dragged the others down domino-style via the electrical, telephone and cable-TV cables strung between them, authorities said.
Three other utility standards on the street also were pulled awry but did not come down, city spokeswoman Monica Zech said.
The poles are jointly owned by SDG&E along with telephone and cable-television providers, according to Albrecht.

EL CAJON, Calif. (AP) - Officials are trying to find out what caused eight utility poles to topple in San Diego County, leaving 1,500 El Cajon residents without power.
City spokeswoman Monica Zech says it's unclear why a pole toppled and brought down the others Thursday afternoon but she says most poles have been replaced Friday morning.
Only about 70 people remain without power and Zech says that should be down to about a dozen by noon.
Nobody was hit when the poles, carrying electrical and cable TV lines, fell down. Zech says a weak pole may have collapsed or a tree limb may have fallen onto it.

EL CAJON (CBS 8/ CNS) - Six power poles toppled over onto an El Cajon street Thursday afternoon, causing road closures and leaving several customers without power.
It happened on Mollison Avenue between Main Street and Washington Avenue. A live report from Chopper 8 showed several of the poles laying in the street, as well as one laying against a light standard.
One pole apparently simply "gave out" and fell over for unknown reasons about 4:30 p.m., dragging five others with it via the cables strung between them, El Cajon Public Information Officer Monica Zech said.
Three other nearby standards also appeared "compromised" but did not come down, Zech said.
Late Thursday night, about 185 customers were still without electricity and waiting in the dark. SDG&E crews were on scene and repairs were expected to stretch into the night.
There were no injuries reported.
