An 85-year-old Lake County resident caused a power outage Thursday evening when she rammed her vehicle into a utility pole while trying to cross Highway 29 from Live Oak Drive in Kelseyville.

A PG&E spokeswoman said Friday morning that 346 customers lost power last night due to the downed utility pole, but only 20 customers remain without electricity this morning. Full repairs are expected to be completed by 9 a.m.

The accident occurred shortly after Anna Elizabeth Willis of Kelseyville, driving a 2003 Pontiac Montana, left the Idle Wheels Mobile Home Park at 5701 Live Oak Drive. Willis attempted to make a left turn and cross Highway 29, CHP officials said.

She crossed both directions of Live Oak Drive and then smashed into the utility pole. The downed power pole and lines caused an immediate loss of electricity to the surrounding area, the CHP said.

Highway 29 was temporarily closed in both directions for about two hours as emergency crews worked to clear the power lines from the road.

The accident is under investigation and alcohol does not appear to be a factor.
