In Pixar's Cars, what desert town does Lightning McQueen accidentally damage and then repair?

In Pixar's Cars, Lightning McQueen accidentally damages and must repair Radiator Springs.

After being separated from his hauler, Lightning becomes lost on a detour from Interstate 40 and reaches the fictional town on historic U.S. Route 66. While trying to escape, he tears up the road, damaging its surface. Doc Hudson, the town judge, orders him to repair it before leaving.

The repair assignment forces Lightning to spend time with Radiator Springs residents including Sally Carrera, Mater, Luigi, Guido, Fillmore, and Flo. At first, he views the town as an obstacle between himself and the Piston Cup. Gradually, he learns its history and forms friendships there.

Radiator Springs is fictional, but its setting reflects real Route 66 communities and landmarks. A common mix-up is confusing the town with Ornament Valley, the broader desert region featured in the film and later Cars media.
