Jefferson National Expansion Memorial : Gateway Arch
The Construction of the Arch began in 1963 and was completed on October 28, 1965, for a total cost of less than $15 million. The Arch has foundations sunk 60 feet into the ground, and is built to withstand earthquakes and high winds. It sways up to one inch in a 20 mph wind, and is built to sway up to 18 inches. Fees are charged to ride the unique tram system to the top.
