The Tacoma Narrows Bridge is a pair of mile-long suspension bridges in the U.S. state of Washington, which carry State Route 16 across the Tacoma Narrows between Tacoma and the Kitsap Peninsula. They replaced a bridge that was opened to traffic on July 1, 1940 and which became famous four months later for a dramatic wind-induced structural collapse that was caught on motion picture film. The original span's motion earned it the nickname Galloping Gertie.
Due to materials shortages as a result of World War II, it took 10 years to build a replacement bridge, which opened October 14, 1950. The 1950 replacement bridge was sometimes referred to as Sturdy Gertie and, like its predecessor, was the third longest suspension span in the world at the time of its construction. Population growth on the Kitsap peninsula caused traffic to exceed the bridge's vehicle capacity, and a parallel bridge was constructed to carry eastbound traffic, while the 1950 bridge was reconfigured to carry westbound traffic. The new bridge opened July 15, 2007.

    Very nice. Have you seen the GigaPan I shot of these bridges from down nearer water level last summer? www.gigapan.org/gigapans/31846/ Yours came out much crisper.
