The first Tacoma Narrows Bridge had the same location as the present day westbound bridge spanning the Tacoma Narrows strait of Puget Sound between Tacoma and Gig Harbour, Washington.
Aerodynamic factors caused a substantial collapse of the original Tacoma Narrows Bridge in November 1940, just four months after opening. The new bridge, opened in October 1950, was a complete replacement, only utilizing the original bridge’s concrete piers and cable anchorages.
In 1997, a third bridge was built alongside the existing bridge to carry SR 16 eastbound traffic to Tacoma.
