Route 66 turns 100 this year!
Established in 1926, Route 66 stretched 2,448 miles from Chicago to Santa Monica, California. Conceived by Oklahoma businessman Cyrus Avery, it connected rural Midwest and Southwest communities, acting as a lifeline for Dust Bowl migrants, a supply route during WWII, and a symbol of mid-century vacation freedom before being decommissioned in 1985.
Key Milestones in Route 66 History
• 1926 (November 11): Route 66 is officially established, linking existing state and county roads into one continuous path from the Great Lakes to the Pacific.
• 1930s (The Dust Bowl): The highway becomes the main thoroughfare for hundreds of thousands of people fleeing the devastated Great Plains for work in California, later immortalized in John Steinbeck's The Grapes of Wrath.
• 1938: Route 66 becomes the first major U.S. highway to be completely paved from end to end.
• 1940s–1950s (The Boom): The post-WWII economic boom ushers in a golden age of American road-tripping. The route spawns a massive culture of neon-lit motels, quirky roadside attractions, and diners.
• 1956: President Dwight D. Eisenhower signs the Federal Aid Highway Act, funding the new Interstate Highway System, which bypasses the older, winding sections of Route 66.
• 1985 (June 27): Route 66 is officially decommissioned and decertified as a U.S. Highway, having been largely replaced by continuous interstates like I-55, I-40, and I-15.
Today, the legacy of the "Mother Road" lives on. Organizations like the National Park Service Route 66 Corridor Preservation Program help preserve and promote surviving alignments and historic roadside architecture. Exploring the route is still a popular tourist activity, and road-trippers can utilize resources like the Historic Route 66 Association of Illinois or Route 66 News to track down original diners, neon signs, and vintage gas stations
