In Pixar's Cars, what road does Radiator Springs lie along?

In Pixar's Cars, Radiator Springs lies along Route 66.

The fictional town is located in the southwestern United States and is presented as a once-busy stop on the historic U.S. Route 66. A highway bypass leaves the community isolated, helping explain why its businesses and population decline before Lightning McQueen arrives.

The film draws heavily on real Route 66 landmarks, landscapes, and roadside architecture. Pixar artists researched the highway during a 2001 road trip, visiting locations in several states and gathering visual references for the desert scenery and small-town atmosphere.

Route 66 originally connected Chicago and Santa Monica and was established in 1926. It was removed from the United States Highway System in 1985, but its cultural importance remains strong. The movie's Radiator Springs is fictional, so it should not be confused with a real town of that exact name.
