The Most Famous Bridge Collapse Ever?

You've probably seen that old black & white footage of the Tacoma Narrows Bridge collapsing after wobbling spectacularly in the wind, even if you don't recognize the bridge by name (or by its nickname, 'Galloping Gertie'). It was replayed incessantly again in the last couple of years amid renewed public concern about our decaying infrastructure. That event occurred on this date in 1940, it turns out.  You can view 1 minute of amazing color footage on You Tube HERE.
