The 1940 Tacoma Narrows Bridge, the first bridge at this location, was a suspension bridge in the U.S. state of Washington that spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula.
The collapse of the original bridge. The first Tacoma Narrows Bridge opened to traffic on July 1, 1940. Its main span collapsed into the Tacoma Narrows four months later on November 7, 1940, at 11:00 a.m. (Pacific time) possibly as a result of aeroelastic flutter caused by a 42 mph (68 km/h) wind. The bridge collapse had lasting effects on ...

On November 7, 1940, the low pressure system that later developed into the storm was affecting the Pacific Northwest and produced the 40 mph (64 km/h) winds that destroyed the Tacoma Narrows Bridge. On November 10 the fast-moving storm crossed the Rocky Mountains in just two hours on its way to the Midwest. [6] [7]
Asked about the footage, a spokesperson for the Washington State Archives pointed me to a 2022 Facebook post from the agency — including a video taken while crossing the Tacoma-Narrows Bridge in ...
The failure of the 1940 Tacoma Narrows Bridge, along with the design of the 1950 Tacoma Narrows Bridge, led to a number of firsts in suspension bridge design. The 1950 bridge was the first to be designed and tested in wind tunnels, and was the first suspension bridge designed and built with hydraulic motion damping devices.
