|U.S. Highway 66 or Route 66 was and is the most famous road in the U.S. Highway system and quite possibly the most famous and storied highway in the world. US 66 originally ran from Chicago, Illinois through Missouri, Kansas, Oklahoma, Texas, New Mexico, Arizona and California before ending at the beach at Santa Monica for a total distance of 2,448 miles (3,940 km).|
U.S. 66 was officially decommissioned in 1985 after it was decided the route was no longer relevant and had been replaced by the Interstate Highway System. Today, however, many Americans enjoy Route 66 nostalgia, and the road exists unofficially as an "historic route" in the states it once crossed on its journey from Chicago to Los Angeles.
