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.
Moisseiff called the Tacoma Narrows Suspension Bridge, the first bridge that he designed as the leading engineer, the "most beautiful bridge in the world." However, he lost his strong reputation when this narrow span across the Puget Sound in Washington State collapsed in a windstorm four months after it opened in 1940.
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 ...
Ammann wrote two reports about bridge collapses, the collapse of the Quebec Bridge and the collapse of the original Tacoma Narrows Bridge (Galloping Gertie). It was the report that he wrote about the failure of the Quebec Bridge in 1907 that first earned him recognition in the field of bridge design engineering.
In addition to the many bridges that Steinman designed, he was consulted on several projects that his firm did not win. Perhaps the most famous of these bridges is "Galloping Gertie," the original Tacoma Narrows Bridge. Steinman consulted extensively with the boosters of the bridge during the 1920s, but his design was not selected.
The Aurora bridge is 2,945 feet long, compared to the 5,979-foot westbound and 5,400-foot eastbound spans of the Narrows bridges. The Aurora bridge was deemed the second-deadliest bridge in the ...
