U.S. Route 66 inspired the fictional road through Radiator Springs in Pixar’s Cars.
The film’s creative team traveled along Route 66 while researching the landscapes, businesses, roadside attractions, and communities that shaped the story. The historic highway connected Chicago and Santa Monica and became strongly associated with migration, tourism, and American road culture.
Radiator Springs reflects the fate of many Route 66 towns after Interstate 40 and other modern highways redirected long-distance traffic. In Cars, the town is bypassed by a new interstate, causing businesses and visitor numbers to decline. The plot turns that historical pattern into a personal story about slowing down and noticing overlooked places.
U.S. Route 66 is often called the Mother Road. It was established in 1926 and officially removed from the United States Highway System in 1985. Pixar’s fictional geography is not an exact map, but its visual details are rooted in real Route 66 research.
