A freeway interchange that funnels traffic off the San Francisco-Oakland Bay Bridge collapsed onto another highway ramp early Sunday after a gasoline tanker truck overturned and caught fire, authorities said.
Authorities said the accident, which closed two sections of road that carry cars through Oakland and then east and south of the city, would cause the worst disruption for Bay Area commuters since the 1989 Loma Prieta earthquake damaged a section of the Bay Bridge itself.
