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.
Cause: Vibration—Sheep herd crossing bridge [20] Tacoma Narrows Bridge: 1940: Nov 7, 1940: Tacoma Narrows (Puget Sound) Cause: Wind/Design flaw—Aeroelastic fluttering (wind dynamics) leading to structural failure Detillion Bridge: Unknown: May 24, 1939: Spokane River: Cause: Collision—Tractor-trailer collision on deck [21] Allen Street Bridge
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 ...

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]
