The Bronx–Whitestone Bridge, which is of similar design to the 1940 Tacoma Narrows Bridge, was reinforced shortly after the collapse. Fourteen-foot-high (4.3 m) steel trusses were installed on both sides of the deck in 1943 to weigh down and stiffen the bridge in an effort to reduce oscillation.
The collapse of the original bridge. The first Tacoma Narrows Bridge opened to traffic on July 1, 1940. Its main span collapsed into the Tacoma Narrows four months later on November 7, 1940, at 11:00 a.m. (Pacific time) possibly as a result of aeroelastic flutter caused by a 42 mph (68 km/h) wind. The bridge collapse had lasting effects on ...

Another bridge was completed to carry eastbound traffic in 2007. In response to concerns after the failure of the Tacoma Narrows Bridge in 1940 and a major San Francisco Bay windstorm in 1951, the Golden Gate Bridge, for which Moisseiff had served as a consulting engineer during construction, was briefly closed.
Tacoma Narrows Bridge: Tacoma, Washington: United States 7 November 1940: Road bridge, cable suspension with plate girder deck Aerodynamically poor design resulted in aeroelastic flutter: 0 killed, 0 injured (1 dog killed) Bridge completely destroyed, no persons killed. One dog killed and three vehicles lost.
On November 7, 1940, the low pressure system that later developed into the storm was affecting the Pacific Northwest and produced the 40 mph (64 km/h) winds that destroyed the Tacoma Narrows Bridge. On November 10 the fast-moving storm crossed the Rocky Mountains in just two hours on its way to the Midwest. [6] [7]
Suspension cables of the 1950 Tacoma Narrows Bridge, 1993. The 1950 Tacoma Narrows Bridge undergoes a rigorous maintenance schedule that is a year-long effort. Maintenance crews often perform replacement of steel parts, and inspect the steel cables and towers at night or at low traffic hours. Painting the bridge is also a drawn-out task.
