On November 7, 1940, “Galloping Gertie” went down. Due to strong lateral winds, his miscalculated resonant frequency achieved a critical level, and while experiencing a strong phase transition, the third longest suspension span bridge in the world collapsed, just 4 months after being built. The Tacoma Narrows Bridge stretched like a steel ribbon across Puget Sound river and soon became famous as the most dramatic failure in bridge engineering history. When Galloping Gertie splashed into Puget Sound, it created ripple effects across the nation and around the world mainly due to this footage (above). The event changed forever how engineers design suspension bridges. In fact, Gertie‘s failure led to the safer suspension spans we use today. These 356 seconds under chaotic regimes were precious…

Relax, enjoy the music, and wide open your eyes as never before…
