SACRAMENTO -- Gov. Jerry Brown will not attend the opening of the new eastern span San Francisco-Oakland Bay Bridge, which is set for the day after Labor Day.

A spokesman for the governor, Jim Evans, said Wednesday that Brown will be on an out-of-state family trip "and will be gone through Labor Day."

Officials plan to close the current span, which has been deemed seismically unsafe, Aug. 28 and open the new one at 5 a.m. Sept. 3, the day after Labor Day.

The decision to open the $6.4 billion bridge comes despite construction problems that had threatened to delay the opening for months.

Federal transportation officials have approved a temporary replacement for broken earthquake-safety bolts that had been installed previously, allowing the Labor Day weekend opening.
