Galloping Gertie

The Tacoma Narrows Bridge opened to fanfare in July, 1940 having been constructed over the previous two years as a Public Works Administration Project.  The bridge donned the name "galloping gertie" during construction, giving to its narrow profile and insufficient stiffness. The bridge famously collapsed on Nov. 7, 1940.

The following are some gif extracts I made just for fun.  They aren't timed properly, and I think one has the imaged reversed.

Stay tuned!
