We all went to Uncle Marts house in St. Louis to visit for the thanksgiving holiday. The first day we went to the Gateway Arch. The Arch is the tallest national monument in the United States at 630 feet.
Construction started in 1963 and the last section of the Arch was put into place on October 28, 1965. The Arch sways a maximum of 18" (9" each way) in a 150 mph wind. The usual sway is 1/2". We all rode to the top of the arch in the "Pods" which are part elevator and part amusement park ride because of the irregular shape of the arch. Take a look!
