Which famous highway is central to the history of Radiator Springs in Pixar’s Cars?

U.S. Route 66 is central to the history of Radiator Springs in Pixar’s Cars.

The fictional town once benefited from travelers using the historic highway across the United States. Its fortunes declined after a faster interstate bypassed the town, leaving its businesses and population isolated. Lightning McQueen’s arrival brings new attention to the community and helps restore local pride.

Route 66 originally connected Chicago and Santa Monica and became one of the best-known roads in American popular culture. It was officially removed from the United States Highway System in 1985, although many surviving sections remain historic attractions.

Pixar artists researched Route 66 while developing the film. The movie includes visual ideas drawn from real roadside towns, desert landscapes, roadside businesses, and landmarks. Radiator Springs is fictional, so it should not be identified with one exact real town; it is a composite inspired by several Route 66 communities.
