The Tacoma Narrows Bridge is a mile-long (1600 meter) suspension bridge with a main span of 2800 foot (850 m) (the third-largest in the world when it was first built) that carries Washington State Route 16 across the Tacoma Narrows of Puget Sound from Tacoma to Gig Harbor, Washington。
The first version of the bridge, nicknamed "Galloping Gertie," was designed by Clark Eldridge and altered by Leon Moisseiff。
In 1940, it became famous for a dramatic wind-induced structural collapse, an event that was caught on film。 The replacement bridge opened in 1950。
