On this date in 1940, one of the most spectacular bridge collapses in U.S. history occurred in Western Washington.
The Tacoma Narrows Bridge, nicknamed "Galloping Gertie," fell into the sound during a windstorm on November 7, 1940. The bridge's collapse was a lesson in poor design and engineering.
Luckily, no was killed or seriously hurt in the incident. One dog did die.
