Tacoma narrows bridgethe tacoma narrows is the single point in the 20,000 square miles of puget sound where the washington mainland and the olympic peninsula the failure on november 7, 1940 marked the end of a trend in bridge engineering towards a maximum of lightness, grace and flexibility. The vast majority of collapses cause only economic losses and are therefore unknown to either academics or engineers hence, the causes of the collapse that may be quite trivial are not discussed by the technical and academic community sometimes there is a connection between engineering malpractice.
The tacoma narrows bridge (also known as galloping gertie) is a well-known and well-documented suspension bridge failure that occurred on november 7, 1940 at approximately 11am, four months after the bridge was first opened to the public.
