The 1940 Tacoma Narrows Bridge was opened to traffic July 1st 1940 and destroyed itself on November 7th of the same year.  I have watched the video of the bridge collapsing and the dramatic movements that happened before the collapse.  What I found interesting is that the motion was observed when the bridge was opened to the public.

The workers who built the bridge named the bridge “Galloping Gertie” because they felt the flexing while they were working. The nickname stuck and became famous after the collapse.

We have been across the new bridge many times and each time I think of the collapse of the original bridge.  The new bridge is beautiful and in a short period of time was not enough and so a second bridge was built.  I wish that when the second bridge was built it had matched the first bridge.
