This suspension bridge was known for its tendency to sway in windy conditions.

Today, visitors can see a piece of the wreckage - a broken girder embedded in concrete - on the 5th floor of the Washington Sta

The Tacoma Narrows Bridge, or “Galloping Gertie,” collapsed on November 7, 1940, just months after opening.
