Tacoma Narrows Bridge, Spanning Narrows at State Route 16, Tacoma, Pierce County, WA

Significance: The Tacoma Narrows Bridge was the first suspension span constructed in the United States after its predecessor's failure in 1940 from wind-induced torsional oscillations. Research of design flaws in the first Tacoma Narrows Bridge led to the use of aerodynamic testing as a standard procedure in suspension span structural analysis, including studies for its replacement.
