Question: when was the first tacoma narrows bridge built
Answer: Historically , the name `` Tacoma Narrows Bridge '' has applied to the original bridge nicknamed `` Galloping Gertie '' , which opened in July 1940 , but collapsed because of aeroelastic flutter four months later , as well as the replacement of the original bridge which opened in 1950 and still stands today as the westbound lanes of the present - day twin bridge complex .
