This approval process cemented Moisseiff's methods as the chosen path, setting the stage for what would become a dramatic lesson in aerodynamics. On November 7, 1940, a twisting motion induced by vortex shedding during a 42-mile-per-hour windstorm led to the catastrophic failure of the bridge.
Original Tacoma Narrows Bridge Design and Engineering Behind Galloping Gertie
The new bridge, completed in 1950, incorporated truss girders within the deck to provide essential stiffness, directly addressing the aerodynamic flaws exposed in the 1940 failure. The journey to construction began with the Washington State Highway Commission, which spearheaded the project to connect the Olympic Peninsula with the mainland.
The collapse was captured on film, searing the image of "Galloping Gertie" into the public consciousness and sending shockwaves through the engineering community. More About Who designed the tacoma narrows bridge Who designed the tacoma narrows bridge can be explained clearly by focusing on the most useful facts first and keeping the details easy to follow.
Original Tacoma Narrows Bridge Design and Engineering Team
While the bridge was praised for its cost-effectiveness and visual appeal, the very flexibility that defined its design became its critical flaw. When people ask who designed the Tacoma Narrows Bridge, the answer involves a collaboration between the Washington State Highway Commission and the engineering firm of Leon Moisseiff.
