What historic road inspired the setting of Pixar’s Cars?

Historic U.S. Route 66 inspired the setting of Pixar’s Cars.

The film’s fictional town of Radiator Springs is presented as a once-busy roadside community bypassed by a newer interstate highway. That idea reflects the real history of Route 66, the famous road connecting Chicago and Santa Monica that became associated with roadside businesses, motels, gas stations, and changing American travel.

Pixar artists and filmmakers traveled along Route 66 while researching the movie. Their observations influenced the landscapes, buildings, signs, and small-town atmosphere seen in Radiator Springs. The film turns those details into a world inhabited by cars rather than people.

Route 66 is often called the “Mother Road,” a phrase popularized by John Steinbeck’s 1939 novel The Grapes of Wrath. It was removed from the United States Numbered Highway System in 1985, but many historic sections remain tourist attractions. Cars helped introduce that road-trip heritage to a new generation.
