In Pixar's Cars, what real-world road inspired the design of Radiator Springs?

U.S. Route 66 inspired the design of Radiator Springs in Pixar’s Cars.

The historic highway shaped the film’s depiction of a once-thriving roadside town left behind when faster interstate travel redirected traffic. Pixar artists and filmmakers researched Route 66 communities, businesses, and landscapes to create a setting that felt connected to real American road culture while remaining a fantasy populated by talking vehicles.

Route 66 originally ran from Chicago to Santa Monica and became famous through migration, tourism, diners, motels, and roadside attractions. It was removed from the United States Highway System in 1985, but many preserved sections remain cultural landmarks.

Radiator Springs is not a direct copy of one town. Its locations combine influences from several Route 66 sites, including the Wigwam Motel and distinctive roadside architecture. That composite approach explains why viewers may recognize real places in the fictional town without finding Radiator Springs on a map.
