March 2004: There was a bridge collapse very similar on I-95 in Connecticut. Tanker truck, fire, bridge collapse.

Of course here in Connectcut, we have bridges that just fall apart all by themselves - http://en.wikipedia.org/wiki/Mianus_River_Bridge
Same on Rt 95 in Philly a few years back.
There was also a Bridge on Route 80 in Denville NJ that was damaged by a tanker fire on June 21,2001. That particular bridge had concrete beams and it STILL was weakened to the point it was unsafe and had to be replaced.
