Tacoma Narrows Bridge

The Tacoma Narrows Bridge is the longest twin suspension bridge in the world. A pair of mile-long (1600 meter) suspension bridges with main spans of 2800 feet (850 m), they carry Washington State Route 16 across the Tacoma Narrows of Puget Sound between Tacoma and the Kitsap Peninsula, USA. The first bridge, nicknamed Galloping Gertie, was opened to traffic on July 1, 1940, and became famous four months later for a dramatic wind-induced structural collapse that was caught on motion picture film. The first replacement bridge opened in 1950, and a parallel bridge opened in 2007.
