In Pixar’s Cars, Sally Carrera identifies Route 66 as Radiator Springs’ historic route.
Route 66 is the famous U.S. highway that once linked Chicago and Santa Monica. In the film, Sally explains that the town flourished when travelers used the road, then declined after Interstate 40 diverted traffic away from its main street.
This history gives Cars more than a racing setting. Radiator Springs represents roadside communities affected by changing transportation patterns, while Sally’s enthusiasm reflects real efforts to preserve Route 66 landmarks and memories. The film presents the route through a fictional town populated by cars.
Route 66 was removed from the U.S. Highway System in 1985, but its cultural importance continued through museums, tourism, preservation projects, and popular culture. Cars helped introduce the route’s visual identity to a worldwide family audience.
