Galloping Gertie

The Tacoma Narrows Bridge got the nickname of Galloping Gertie in 1940 when winds created a harmonic resonance in the bridge structure. It’s hard to believe that steel, concrete, and asphalt can be so flexible :slight_smile:


Great resource for bridge builders.
It took a while till the bridge collapsed.

Good brakes on the car, too!
Even small structures or buildings are constantly moving, btw.
You might not see it directly, but only in time…

In a former life, I would’ve surfed this on my 'board while yelling “Gnarly!!!”
