You just can’t miss it! Wherever you are in the city, and however you arrive it is, well, monumental!
This is the tallest national monument in the United States at some 630 ft. There are 900 tons of stainless steel in the arch. The engineering tolerances of this amazing structure are so fine that there could be no more than a 1/64th inch margin of error as to where the legs would meet. The Arch normally sways around ½ inch, but is designed to sway a maximum of 18" (9" each way) in a 150 mile per hour wind. Inside there are small bubble-style lifts to take visitors to the top for the best view in town.
