Watch the amazing "Gallopin' Gertie" November 7, 1940 film clip. 1940 Tacoma Narrows Bridge Slender, elegant and graceful, the Tacoma Narrows Bridge stretched like a steel ribbon across Puget Sound in 1940. The third longest suspension span in the world opened on July 1st. Only four months later, the great span's short life ended in disaster. "Galloping Gertie," collapsed in a windstorm on November 7,1940.
The bridge became famous as "the most dramatic failure in bridge engineering history." Now, it's also "one of the world's largest man-made reefs." The sunken remains of Galloping Gertie were placed on the National Register of Historic Places in 1992 to protect her from salvagers.
A dramatic tale of failure and success The story of the failure of the 1940 Narrows Bridge and the success of the Current Narrows Bridge is a great American saga. When Galloping Gertie splashed into Puget Sound, it created ripple effects across the nation and around the world. The event changed forever how engineers design suspension bridges. Gertie's failure led to the safer suspension spans we use today.

Galloping doesnt need high wind to appear. The bridge came into resonance vibration because of the wind. Not necesary high. The car maybe could help avoid galloping, if it were in the right place
I read somewhere, perhaps the source wasn't accurate, that the bridge bended like that even with slow wind, and cars drivers that dared crossing the bridge sometimes couldn't see the car in front of them due of the oscillation.
the bridge is lower than the trees in the background it was just that the speed of the wind be it 20mph or 80mph made the bridge vibrate and set in motion the swaying
