State Route 66, often referred to as the "Mother Road," is a historic highway in the United States that originally ran from Chicago, Illinois to Santa Monica, California. Established in 1926, it spans approximately 2,448 miles and was a major route for those migrating west during the Great Depression. The highway played a significant role in American culture, symbolizing freedom and adventure. Although it was officially removed from the U.S. Highway System in 1985, many sections of Route 66 have been preserved and are celebrated for their nostalgic charm, attracting tourists and road trip enthusiasts.
