WEST SACRAMENTO, Calif. -- A crane on a barge hit power lines over the Sacramento River, leaving thousands of people without power Thursday evening.

The barge was turning around in the Deep Water Channel at about 6:15 p.m. when the crane hit the lines, the Pacific Gas & Electric Co. said.

The transmission lines went into the water, PG&E said. According to the U.S. Coast Guard, the uncharged lines don't pose an immediate threat to boaters.

PG&E estimated power wouldn't be restored for about 5,600 customers until early afternoon Friday. Power for another 3,000 customers might be back late Thursday night.

At about the same time as the crane's crash, a vehicle hit a pole in the 3000 block of Peter Island Road. Officials initially said the car crash caused some outages, but PG&E later said the crane was to blame.
