Tacoma Narrows Bridge disaster, November 7, 1940. Many times a picture is insufficient to do the job and this very short video shows the magnitude of the disaster. The Tacoma Narrows bridge was completed in July 1940 but on Nov 7, 40mph winds created a resonance pattern that caused the bridged to tear itself to pieces. A dog trapped in a car was the only fatality. The bridge cost millions to construct and only lasted a few months. A new bridge was not built til more than 10 years later.
Brooklyn Bridge. At the time the bridge was built, the aerodynamics of bridge building had not been worked out. Bridges were not tested in wind tunnels until the 1950s, well after the collapse of the original Tacoma Narrows Bridge (Galloping Gertie) in 1940. It is therefore fortunate that the open truss structure supporting the deck is by its nature less subject to aerodynamic proble
Perhaps the Most Spectacular Bridge Collapse Ever Caught on Film
