Isaac Rodriguez rushed into the night from the Oakland sewage treatment plant where he works and found a blinding light -- a curtain of fire engulfing the elevated freeway ramps nearby.
A tanker truck carrying 8,600 gallons of gasoline had overturned at 3:41 a.m. and burst into flames on the 50-foot-high ramp connecting westbound Interstate 80 to southbound Interstate 880. Within minutes, the ramp above it -- connecting eastbound I-80 to eastbound I-580 -- collapsed in the 3,000-degree cauldron.
