From its earliest days, Route 66 has reflected the American culture of the moment.

When the road connected Chicago to Los Angeles in 1926, it represented the possibility of the automobile. In the 1930s, it served as an east-to-west escape route from the Dust Bowl during the Great Depression. By the 1950s, the 2,400-mile highway lured travelers with the post-World War II promise of adventure on the open road. And as the era of interstate highway driving dawned, Route 66 began to reflect a yearning for a time when a journey was about more than the destination.

Now the eight states traversed by America’s defining highway are getting it ready for its 100th anniversary, in 2026. States are handing out grants to restore vintage neon signs along the highway. They’re installing shoulders to make the road safer for bicyclists and improving signage to make the route more obvious through cities. And they’re installing charging stations that will make it easier to travel the entire length in an electric vehicle.
