"Galloping Gertie" was the nickname for the first Tacoma Narrows Bridge, which opened on July 1, 1940, and spectacularly collapsed on November 7, 1940, due to aeroelastic flutter caused by strong winds. It was the third longest suspension bridge in the world at the time and its failure significantly impacted bridge engineering. No human lives were lost, though a dog named Tubby was on the bridge and lost with a car❤️ | Wander Wonder

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.
