Highly impressive rest stop: Mclean, Texas

I was on the opposite side of I-40/historic 66 headed in the wrong direction when I spotted this, but I had to stop and take a picture. It’s a rest stop that’s embedded into the side of the hill.

What caught my eye was the beauty of its construction, but now that I’m reading up on it’s designed this way in order to function as a Tornado shelter (this being Tornado Alley)
