A limousine traveling on the San Mateo Bridge area burst into flames, killing five people and sending four others to hospitals, authorities said.
The five who died became trapped after the limo caught fire late Saturday night on the bridge, California Highway Patrol officer Amelia Jack told a Bay Area news agency.
Five others managed to escape after the vehicle came to a stop on the bridge, she said.
The victims were all women who were believed to be in their 30s, according to the news organization.
The blaze occurred around 10 p.m. on westbound lanes of the bridge, which connects San Mateo and Alameda counties.
The patrol said that smoke started coming out of the rear of the limo, and the driver pulled over as the vehicle quickly became engulfed in flames.
"We have no idea right now where they were going or where they were coming from," Jack said.
Of the survivors, Jack said one had severe burns and three others suffered minor to moderate injuries that included smoke inhalation. The four were rushed to nearby hospitals for treatment, while the fifth person who escaped wasn't hospitalized.
The driver, 46-year-old San Jose resident Orville Brown, also made it out without major injury.
Several lanes of the bridge were closed as officers investigated the cause of the deadly fire, but the patrol said one lane of traffic reopened early Sunday.
Watchdogs are questioning an exclusive agreement between the City of Oakland and a non-profit group, tapped to lead a multi-million dollar project to redevelop the area around the Coliseum BART station.
