Watch VoirFilms. Today’s video Doodle takes you on the ultimate American road trip, a journey along the historic Route 66. The iconic highway—known for its retro diners, quirky motels, eclectic art installations and extraordinary landscapes—connects Chicago, Illinois to Santa Monica, California. On this day in 1926, the name “U.S. 66” was first proposed for the cross-country route. The video—set to the classic music track "Route 66" by Bobby Troup—celebrates the cultural significance of one of America’s first national highways, and how it became a symbol of a changing nation.
