The better look out for trucks....because I think that is the only way they can take out the bridges...trucks full of diesel fuel and fertilizer slammed.

The (only) bridge to South Padre Island, TX was taken out by a tug boat pulling (or pushing?) 4 barges. Happened a week or two after 9/11. It'll be out of commission until December.

In war bombardment taking out a bridge requires obliterating one or both of the bases, not the span.
That said, how big of a pay load would be needed to take out the span?
Still A lot!

HOW MANY people does the Golden Gate Bridge transport at one time, during rush hour? Anyone know?
