The image of Leonard Coatsworth’s car stuck on the swaying Tacoma Narrows Bridge known as Galloping Gertie might be one of the most well known from that disaster, but though it’s dramatic it does little to give viewers a true sense of just how large a span of the bridge collapsed. Wind caused the bridge to sway back and forth, and it also sent rippling waves along the deck. The Tacoma Narrows tore itself apart only four months later. Years later, engineers found that the solid girders actually blocked the wind and caused the slender bridge to twist. The Tacoma Narrows Bridge collapsed primarily due to the aeroelastic flutter.
