<P> The Tacoma Narrows Bridge is a pair of twin suspension bridges that span the Tacoma Narrows strait of Puget Sound in Pierce County , Washington . The bridges connect the city of Tacoma with the Kitsap Peninsula and carry State Route 16 ( known as Primary State Highway 14 until 1964 ) over the strait . 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 . </P>
