Route 66

From Chicago to California, Route 66 has been replaced in segments by the newer Interstate Highway System, but enthusiasts can still navigate many of the original 2,448 miles. The route is littered with old hotels and roadside attractions from when the highway was at its peak.

Seligman, Arizona, has 456 residents and was an inspiration for the 2006 Pixar film "Cars." The Harvey House Railroad Depot in Barstow, California, houses the free Route 66 Mother Road Museum.
