Washington is a state with many bodies of water to cross, including Puget Sound, Hood Canal, the Columbia River and numerous smaller rivers and creeks. It has experienced a number of bridge failures before and after the well known Tacoma Narrows Bridge collapse in 1940.
The single greatest cause of failure in Washington has been flooding, frequently associated with severe storms, which then results in destructive bridge scour. [1] [2] [3] According to University of Washington meteorologist Cliff Mass, Western Washington is "particularly vulnerable to such bridge losses, with long floating bridges and the powerful winds associated with our terrain and incoming Pacific cyclones." [3]

The Tacoma Narrows Bridge is a pair of twin suspension bridges that span the Tacoma Narrows strait of Puget Sound in Pierce County, Washington. The bridges connect the city of Tacoma with the Kitsap Peninsula and carry State Route 16 over the strait. Historically, the name "Tacoma Narrows Bridge" has applied to the original bridge, nicknamed "Galloping Gertie", which opened in July 1940 but collapsed possibly because of aeroelastic flutter four months later, as well as to the successor of that bridge, which opened in 1950 and still stands today as the westbound lanes of the present-day two-bridge complex.

It was intended to be the prototype "for countless similar shelters that would be installed nationwide under interstate highways".
