What is the name of the bridge that fell apart due to thermal expansion? It had wave like features before fall

Question

It was in the 1950's or 60's. There is a video of the bridge showing some wave like behaviors before falling. I believe it was somewhere in the middle of the USA. It was also featured in a radio/ or car commercial.

Answer 1

wasn't that the bridge on the river kwai  just as Alec Guinness presses the plunger

Answer 2

It was out in Seattle or somewhere.  It may have been the Tacoma Narrows bridge.  And I thought it was a wind problem, like the bridge was built exactly to the harmonic vibration of a constant 45mph wind because they didn't think that would ever happen.  

I dunno.  Something like that.

Answer 3

It was 1940 and the Tacoma Narrows bridge. It wasn't thermal expansion though, it was being blown up and down like a sail in the very high winds. The videos are based on film taken at the time when people complained about the roadway bouncing.
