Opened on October 14, 1950, it was built in the same location as the original Tacoma Narrows Bridge, which collapsed due to a windstorm on November 7, 1940. It is the older of the twin bridges that make up the Tacoma Narrows Bridge crossing of the Tacoma Narrows, and carried both directions of traffic across the strait until 2007. At the time of its construction, the bridge was, like its predecessor, the third-longest suspension bridge in the world in terms of main span length, behind the Golden Gate Bridge and George Washington Bridge; it is now the 31st longest suspension bridge in the world. Design work on a new Tacoma Narrows Bridge began shortly after the collapse of the original bridge. However, several engineering issues, the demand on steel created by the United States' involvement in World War II, and the state of Washington's inability to find an insurer, all pushed the start of construction to April 1948. The new bridge was designed with a wider deck and taller and wider towers than its predecessor, and addressed the wind issues that led to the original bridge's collapse. It opened to the public on October 14, 1950, and carried both directions of Primary State Highway 14 for over 40 years. Tolls were charged on the bridge until 1965, 13 years ahead of...
