The Tacoma Narrows Bridge, also known as "Galloping Gertie", collapsed on November 7, 1940, just a few months after opening. This suspension bridge was known for its tendency to sway in windy conditions. However, on that fateful morning, the bridge failed due to a combination of lightweight construction and strong wind pressure on the 8-foot solid plate girder and deck.

The Tacoma Narrows Bridge, or “Galloping Gertie,” collapsed on November 7, 1940, just months after opening. The bridge’s deck twisted and undulated in response to strong winds, succumbing to aeroelastic flutter. This phenomenon, where aerodynamic forces matched the bridge’s natural frequency, led to its dramatic collapse into the Tacoma Narrows strait. no lives were lost in the collapse.
