I came across a blog post of the world’s 10 greatest bridges. The New River Gorge bridge in West Virginia made the list and is pictured below.

I’ve always enjoyed the beauty and grace of well designed bridges. My own list would include a Robert Maillart bridge as well as a wooden covered bridge.

Do you have one weird pick for a bridge favorite?

Speaking of bridge favorites, you may want to watch this 1940s newsreel of the collapse of the Tacoma Narrows bridge.

It’s instructive to watch that video occasionally to be reminded of the power of harmonic frequency. My favorite part of the footage is watching the old guy in the pick-up truck stuck on the bridge.
