The Saint Louis Gateway Arch resembles the image of a rainbow symbolizing hope. Its metal structure is a symbol of strength. The American flag in front and centered under the Arch symbolizes the unity of all states and how each state contributes to that strength. A member of the National Guard is parachuting through the Arch with the colors of the United States, symbolizing the faith we have in our military to get the nation through every crossroad (smoke from plane in the form of an X) the country may face.
