Known variously as the Ozark Trail, the Will Rogers Highway, Main Street America, and the Mother Road, Route 66 is closely associated in Arcadia with the Round Barn, a landmark built in 1898 by W.H. Odor. After the route was designated a national highway in 1926, improvements were made to the 1917 roadbed. The original road between Edmond and Arcadia was constructed by convict labor, and the highway through Arcadia was paved in 1929. Many Arcadia businesses served travelers with gasoline stations, cafes, lodging facilities, and a grocery and general store.
