Galloping Gertie

When the original Tacoma Narrows bridge was built in 1940, its design inadvertently caused it to resonate with the wind gusts through the Narrows. The bridge had a tendency to sway in the wind, which earned it the nickname "Galloping Gertie." The ultimate fate of this constant swaying is dramatically illustrated in the following newsreel.



The bridge even made an appearance in an advertisement for Pioneer speakers in the '90s.
