A story of engineering progress, the Tacoma Narrows Bridge is located close to Tacoma, Washington. Aerodynamic instability caused the original 1940 bridge, commonly known as “Galloping Gertie,” to collapse a few months after it opened, costing $6 million. The replacement, built in 1950 for $14 million, and the $849 million eastbound span built in 2007 are examples of the progress made in bridge design and construction.
