The arch has 60-foot deep foundations. The arch is very stable and was built to withstand high winds and earthquakes. The structure sways about one inch in a 20 mph wind; it is designed to sway up to 18 inches in 150 mile per hour winds.
I guess whats funny is the fact that it looks...so insignificant like a whined up toy lol and moving really fast as if its a speed boat lol im laughing at this and im not even high lol.
Amazing time lapse!

@StLouisEarl
One inch only for 20mph? Ive been up there and it feels like feet more than inches. Ive heard it can sway up to 7 feet...3 1/2 feet to each side!
