From the USPS on October 29, 2025:

With these stamps, the Postal Service celebrates the 100th anniversary of Route 66, the legendary highway that originally stretched about 2,400 miles from Chicago to Los Angeles. Dubbed “The Mother Road” by author John Steinbeck, Route 66 forever changed how Americans travel and became a symbol of freedom and adventure. The pane of 16 stamps includes photographs by David Schwartz from each of the eight states Route 66 passes through, with each one repeated twice. The selvage features a photo by Schwartz of the open road rolling through hills in Crookton, AZ, along the longest continuous drivable stretch of Route 66 in the state.

More details will be posted below the line, with the most recent information at the top.

Background: For a century, drivers have hit the open road chasing the American dream along Route 66, the legendary highway that originally stretched about 2,400 miles from Chicago to Los Angeles. Dubbed “The Mother Road” by author John Steinbeck, Route 66 forever changed how Americans travel and became a symbol of freedom and adventure. Route 66 was established on Nov. 11, 1926, connecting rural communities across eight states. During the Great Depression, people seeking better opportunities drove Route 66 west, and it became a symbol of postwar optimism. Along the route, mom-and-pop cafes, drive-in restaurants, souvenir shops, curiosities, motels and gas stations with neon signs highlighted the journey.

The Federal-Aid Highway Act of 1956 provided funding for a new interstate highway system, and Route 66 was gradually replaced. Route 66 still unites the country with its call for adventure in pursuit of freedom and possibility on the open road.

Eight different photographs, featured twice on the stamp pane, show a site from each state that Route 66 runs through. The selvage features a photograph of Route 66 stretching into the distance in Arizona, capturing the sense of possibility the open road inspires. Greg Breeding, an art director for USPS, designed the stamps and stamp pane using existing photographs by David J. Schwartz.
