In the late 1920's, concrete arrows, along with lighted beacon towers, were used for U.S. airmail. Pilots used these arrows to guide the way to their destination. They were originally painted bright yellow, and on a clear day, the pilot could see the arrow from 1,000 feet above the ground. These directional arrows are spaced about 10 miles apart, and were 50 to 70 feet in length. As time passed, and technology developed, the arrows became obsolete. They were decommissioned in the 1940's.
