In Video: 1940 Tacoma narrows bridge collapse
Watch this amazing footage of the famous Tacoma bridge failure
The original Tacoma Narrows Bridge opened on July 1, 1940. and earned its nickname "Galloping Gertie" by construction workers after they noticed the effect the wind had on the bridge during its build.
The bridge collapsed into Puget Sound the morning of November 7, 1940, under high wind conditions, as this video clearly demonstrates. The bridge had been open for just four months.
It was rebuilt following WWII and now consists of two suspension bridges that carry State Route 16 across the Tacoma narrows between Tacoma and the Kitsap peninsula.
The bridge was designed by Latvian born suspension bridge engineer Leon Moisseiff who also was involved in the deign of New York's Manhattan Bridge, Delaware's Benjamin Franklin Bridge and his theories were used by Charles Ellis to design San Francisco's golden Gate Bridge.
