Route Sixty-Six's Green Book: The Racially Stratified Mother Road
Near Williams, Arizona
John Steinbeck called Route Sixty-Six the Mother Road in nineteen thirty-nine. He was writing about the Dust Bowl refugees, the white Oklahoma and Texas farm families loading their possessions into trucks and driving west to California. The image of Route Sixty-Six that has come down to us, the chrome and neon and freedom mythology, traces directly to "The Grapes of Wrath" and to the romantic version of American mobility that book made possible.
Steinbeck did not write about Black travelers.
A postal worker in Harlem named Victor Hugo Green began publishing an annual guide in nineteen thirty-six called "The Negro Motorist Green Book." Its purpose was practical and urgent: to tell Black Americans driving the roads of the United States which hotels would admit them, which restaurants would serve them, which filling stations would let them use the restroom, and which towns required them to be gone before dark. The Green Book was not a curiosity. It was a survival document for people navigating a road system in which the freedom to travel was conditional on race.
Arizona's Route Sixty-Six corridor ran through communities with varying histories of racial restriction. The Green Book's listings for the Arizona stretch were sparse. Where exactly formal restrictions applied and where informal hostility operated instead is documented unevenly in the historical record. Specific municipal ordinances in specific Arizona Route Sixty-Six towns require verification against local archives and the Black press of the period, including the Chicago Defender and the Pittsburgh Courier, to confirm at the level of documentary precision those records can provide.
What is documented: the Dust Bowl migration that Route Sixty-Six mythology celebrates was predominantly a white migration, on a road that was not equally open to all Americans. The Green Book ran annually from nineteen thirty-six to nineteen sixty-seven. It stopped publishing when the Civil Rights Act made its existence theoretically unnecessary. The road the nostalgia industry has lovingly restored has not yet fully restored this history.
