Nobody's Fool

I'm just supposed to take the word of some officials that 8,600 gallons of fiery fuel is enough to collapse a freeway? Please:

A stretch of highway near the San Francisco-Oakland Bay Bridge collapsed Sunday after a gasoline tanker crashed and burst into flames, a loss that officials said could leave freeways leading to one of the nation's busiest spans in near paralysis at rush hour. Officials said traffic will be disrupted for weeks, if not months.

Flames shot 200 feet in the air and the heat was intense enough to melt part of the freeway and cause the collapse, but the truck's driver walked away from the scene with second-degree burns. No other injuries were reported in the 3:45 a.m. crash, which officials said could have been deadly had it occurred at a busier time.

Sounds like BS to me. I wonder what really happened?
