The 1940 Tacoma Narrows Bridge, the first bridge at this location, was a suspension bridge in the U.S. state of Washington that spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7 of the same year. [1]
Footage of the old Tacoma Narrows Bridge collapsing (19.1 MB video, 02:30). The first Tacoma Narrows Bridge was a suspension bridge in Washington that spanned the Tacoma Narrows strait of Puget Sound. It dramatically collapsed on November 7, 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 ...
Wind caused 1940 Tacoma Narrows Bridge collapse. Ibrahim and Yang Lu, an associate professor of civil engineering at Boise State and an expert in forensic analysis of failed structures, ...
The designs for the 1950 Tacoma Narrows Bridge were drawn up not long after the 1940 collapse of its predecessor. In July 1941, the Washington Toll Bridge Authority appointed Charles E. Andrew (who had been involved in Gertie's design and construction as a consultant) as principal engineer and chairman of the consulting board in charge of designing a new span across the Narrows.
Altogether, it is very unlikely that something similar to the bridge collapse in Baltimore would happen in the Tri-Cities region. The third span of the Tacoma Narrows under construction in 2006 ...
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]
