A brief summary of events surrounding the alarming collapse of America's Tacoma Narrows Bridge, on November 7th, 1940, is provided, followed by comments from one of the actual observers of the collapse, Professor F. B. Farquharson of the University of Washington. A difference of opinions concerning the actual cause of the collapse has since led to considerable strife between two of the bridge industry's most prominent individuals - Mr. 0. H. Anmann and Mr. D. B. Steinman, This tragic accident served as a seed for the birth of today's bridge aerodynamics. Advancements in bridge aerodynamics facilitated:(1) the reconstruction of the Tacoma Narrows Bridge;(2) the construction of the Mackinac Bridge, which, at completion, boasted of the longest suspension spans in the world; and (3) the recent development of streamlined (aerofoil) box sections.
