Tacoma Narrows BridgeThe 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 the bridge to exceed its 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, making the Tacoma Narrows Bridge the longest twin suspension span in the world.
