The road runs deep here.
Tulsa road advocate Cyrus Avery helped champion the highway that became U.S. 66. In 1926, it joined existing roads into a national route linking Chicago and Southern California. Oklahoma was one of its essential chapters.

A road for work. A road for hope.
During the Depression, it carried families west in search of work. The Dust Bowl made that journey part of Oklahoma’s identity. John Steinbeck’s The Grapes of Wrath helped fix the name “Mother Road” in the American imagination.
Main Street became a destination.
Motor courts, service stations, diners and eye-catching signs grew around the traffic. After World War II, family vacations brought another kind of traveler. A small town could become part of somebody’s great American road trip.
The road was not equally open.
Segregation made travel dangerous and uncertain for Black motorists. Near Luther, the Black-owned Threatt Filling Station offered service when many businesses refused it. That history belongs beside the neon and nostalgia.
These were never empty lands.
The highway crossed Native homelands and living tribal communities. Native perspectives are part of the road’s history and present, not simply a theme in roadside souvenirs.
