OAKLAND, Calif. – The threat of a nightmarish morning commute led many Bay Area residents to use public transportation Monday, one day after a fiery tanker crash caused a heavily trafficked section of freeway to collapse.
Westbound traffic into the city largely flowed as usual Monday morning, except for drivers slowing on interchange lanes headed to the Bay Bridge to look at the damage.
But officials warned the afternoon drive would bring bigger headaches as traffic leaving the city is diverted away from the collapsed eastbound segment.
The elevated section of highway that carries motorists from the San Francisco-Oakland Bay Bridge to a number of freeways was destroyed early Sunday when the heat of a burning gasoline tanker truck weakened part of one overpass, crumpling it onto another.
Authorities predicted that overall the crash would cause the worst disruption for commuters since the 1989 Loma Prieta earthquake damaged the Bay Bridge itself. The sight of the soaring freeway twisted into a fractured mass of steel and concrete was reminiscent of that quake's damage.
"The most worrisome thing is the afternoon commute coming out of San Francisco toward the maze because the traffic from the Bay Bridge fans out from across three freeways," said Jeff Weiss, a spokesman for the California Department of Transportation. "Taking away two-thirds of the capacity is really going to cause a bottleneck."
Nearly 75,000 vehicles used the damaged portion of the road every day. But because the accident occurred where three highways converge, authorities said it could cause problems for hundreds of thousands of commuters. State transportation officials said 280,000 commuters take the Bay Bridge into San Francisco each day.
To encourage motorists to switch to public transit, Gov. Arnold Schwarzenegger authorized free passage Monday on ferries, buses and the Bay Area Rapid Transit rail system. Extra trains were added and bus and ferry operators also expanded service.
Parking lots at outlying BART stations filled up earlier than usual for the morning commute.
"I'm mad," said Crystal McSwain, who has a commuter pass to take a trans-bay bus but switched to the more expensive BART. "My life is upside down, and I don't know how long it's going to take."
However, while some trains appeared more crowded than usual, BART officials said overall ridership did not appear greater than normal. Riders likely delayed their morning commute to avoid crowds, or stayed home, BART spokesman Jim Allison said.
Transportation officials said it could take months to repair the damaged interchanges. Schwarzenegger declared a state of emergency to speed up cleanup and rebuilding efforts.
Despite the fire, the truck's driver walked away with only second-degree burns. James Mosqueda, 51, of Woodland, went to a gas station and called a taxi for a ride to a hospital, California Highway Patrol Officer Trent Cross said.
A preliminary investigation indicated Mosqueda may have been speeding on the curving road, he said. Mosqueda could not be reached for comment Monday; hospital officials would not transfer a call to him.
Police said he was headed from a refinery in Benicia to a gas station near the Oakland airport when the accident occurred early Sunday on the MacArthur Maze, a network of ramps and interchanges at the edge of downtown Oakland and about a half-mile from the Bay Bridge toll plaza.
Heat exceeded 2,750 degrees, softening and buckling steel beams and melting bolts, California Department of Transportation director Will Kempton said.
The cost of the repairs would likely run into the tens of millions of dollars, and the state was seeking federal disaster aid, Kempton said.
San Francisco Mayor Gavin Newsom said the accident showed how fragile the Bay Area's transportation network is, whether to an earthquake or terrorist attack.
"It's another giant wake-up call," Newsom said.
