The original Tacoma Narrows Bridge opened on July 1, 1940, and dramatically collapsed into Puget Sound on November 7 of the same year. The suspension bridge spanned the Tacoma Narrows strait between Tacoma and the Kitsap Peninsula. Its replacement was opened in the same location in 1950, and a second, parallel bridge opened in 2007. The instability in winds inspired the nickname Galloping Gertie.
