Route 66 history begins in the heart of 1920s America, when the automobile was transforming the nation and a new road promised to connect Chicago to Los Angeles. Known as the Mother Road, Route 66 became far more than a road. It became a symbol of freedom, migration, and the American dream, and its story still captures the imagination of travelers around the world.
Stretching about 2,400 miles across eight states, Route 66 carried Dust Bowl families westward, soldiers home from war, and vacationers seeking adventure. Though it was officially removed from the highway system in 1985, the Mother Road never truly died. Today, its neon signs, roadside diners, and small towns draw millions of visitors eager to experience a piece of living history.
Route 66 History: How the Mother Road Was Born
The story of Route 66 history starts with a number. On November 11, 1926, the American Association of State Highway Officials designated U.S. Highway 66 as part of the new federal highway system. The route ran from Chicago, Illinois, through Missouri, Kansas, Oklahoma, Texas, New Mexico, and Arizona, ending in Santa Monica, California.
One of the driving forces behind the highway was Cyrus Avery, a Tulsa businessman often called the “Father of Route 66.” Avery championed a diagonal route that would connect the Midwest to the West Coast, and he worked tirelessly to promote the highway and the towns along it. His vision was a road that would serve farmers, truckers, and travelers alike.
Route 66 was not built all at once. In its early years, much of the road was unpaved dirt or gravel. It was not fully paved until 1938. But even before that, the highway was already changing America, giving small towns their first steady stream of travelers and businesses their first taste of roadside commerce.
The Dust Bowl and the Great Migration West
Route 66 history became deeply tied to one of the hardest chapters in American life: the Dust Bowl of the 1930s. As drought and dust storms devastated farms across the Great Plains, hundreds of thousands of families packed their belongings and headed west, many of them along Route 66 toward California.
Author John Steinbeck captured this migration in his 1939 novel The Grapes of Wrath, in which he called Route 66 the “Mother Road, the road of flight.” The name stuck. For the Joad family of the novel, and for real families like them, the highway was both an escape route and a lifeline, leading toward the hope of work and a better life.
The migrants, often called “Okies” regardless of which state they came from, faced hardship along the way. Cars broke down, money ran out, and California’s welcome was not always warm. Yet the journey itself became part of the American story, and Route 66 became its most famous symbol.
The Golden Age of Route 66
After World War II, Route 66 entered its golden age. Returning soldiers bought cars, families took road trips, and the highway boomed. Motels, diners, gas stations, and roadside attractions sprang up along the route, each competing to catch the eye of passing travelers with neon signs and quirky novelties.
This was the era of the drive-in, the motor court, and the giant roadside statue. Towns like Tucumcari in New Mexico, Amarillo in Texas, and Flagstaff in Arizona thrived on tourist dollars. The highway also inspired popular culture. In 1946, Bobby Troup wrote the song “(Get Your Kicks on) Route 66,” which became a hit for Nat King Cole and later for the Rolling Stones, Chuck Berry, and many others. The song name-checked cities along the route, from St. Louis to Los Angeles, and fixed Route 66 in the national imagination.
In 1960, the television series Route 66 brought the highway into living rooms across America, following two young men traveling the road in a Corvette. For a generation, the show made the highway synonymous with freedom and adventure.
Decline and Decertification of Route 66
The same forces that made Route 66 famous eventually doomed it. Beginning in the 1950s, the Interstate Highway System, championed by President Dwight D. Eisenhower, built faster, straighter highways that bypassed the small towns along Route 66. Interstate 40, Interstate 44, and Interstate 55 gradually replaced the old road.
As traffic moved to the interstates, businesses along Route 66 withered. Motels closed, diners emptied, and some towns nearly vanished. The final stretch of Route 66 was bypassed by Interstate 40 in Arizona in 1984, and on June 27, 1985, the highway was officially decommissioned. The road signs came down, and Route 66 disappeared from official maps.
But the story did not end there. Almost immediately, preservationists, business owners, and fans began fighting to save what remained. State governments designated stretches of the old road as Historic Route 66, and travelers kept coming, drawn by nostalgia and curiosity.
Iconic Stops Along Historic Route 66
Today, driving the surviving segments of Route 66 is one of America’s great road trips. Some of the most beloved stops include:
- Chicago, Illinois, where the route begins at the famous “Begin” sign on Adams Street
- Springfield, Missouri, often called the birthplace of Route 66, where the highway got its name in 1926
- Tulsa and Oklahoma City, Oklahoma, home to the Cyrus Avery legacy and the National Cowboy and Western Heritage Museum
- Amarillo, Texas, where the Cadillac Ranch art installation stands half-buried in a field
- Albuquerque, New Mexico, where the route runs along Central Avenue past vintage motels and neon signs
- Petrified Forest National Park in Arizona, the only national park that Route 66 passes through
- Flagstaff and Williams, Arizona, gateways to the Grand Canyon
- Santa Monica, California, where the route ends at the Pacific Ocean and the famous “End of the Trail” sign
Other quirky landmarks include the Blue Whale of Catoosa in Oklahoma, the Wigwam Motel in Holbrook, Arizona, and the giant fiberglass muffler men that still guard some roadside businesses. Each stop tells a piece of the Route 66 history story.
Route 66 and American Culture
Few highways have shaped a nation’s culture like Route 66. Beyond Steinbeck’s novel and Troup’s song, the road has appeared in countless films, books, and songs. The 2006 Pixar film Cars drew heavily on Route 66 towns, with the fictional Radiator Springs inspired by real places like Seligman, Arizona, and Galena, Kansas.
The highway also reflects deeper American themes. It is a story of migration and reinvention, of small-town enterprise and big dreams. For immigrants and travelers from around the world, driving Route 66 has become a bucket-list pilgrimage, a way to experience the America of legend.
The roadside culture of Route 66 also shaped modern travel. The motel, the fast-food restaurant, and the roadside attraction all matured along this highway. In many ways, Route 66 taught America how to travel by car.
The spirit of the open road also runs through the history of the American cowboy, whose frontier trails crossed many of the same plains and deserts the highway later followed. And for travelers who love America’s protected landscapes, our guide to how many national monuments the USA has covers more treasures worth a detour.
The Revival of the Mother Road
In recent decades, Route 66 has enjoyed a remarkable revival. Route 66 associations in all eight states work to preserve historic buildings, restore neon signs, and promote tourism. The National Park Service runs a Route 66 Corridor Preservation Program that helps protect historic properties along the route.
Interest surged again as the highway’s centennial approached. In 2026, Route 66 turns 100 years old, and celebrations, road trips, and restoration projects are marking the milestone across the country. Towns that once feared extinction now welcome visitors from Europe, Asia, and South America, all eager to drive the Mother Road.
Some stretches of the original road are gone, replaced by interstates or returned to farmland. But an estimated 85 percent of the original route remains drivable today, much of it signed as Historic Route 66. With a good map and a sense of adventure, modern travelers can still follow the path of the Dust Bowl migrants, the postwar tourists, and the dreamers who made the road famous.
Planning Your Own Route 66 Road Trip
If you are planning to drive Route 66, give yourself at least two weeks for the full journey. The road rewards slow travel: the best experiences are found in the small towns, diners, museums, and roadside stops along the way. Start in Chicago and head west, so you finish at the Pacific Ocean.
Carry a dedicated Route 66 guidebook or map, since GPS systems often route you onto the interstate instead of the historic alignment. And be ready for surprises: a closed road, a restored gas station, or a local festival can turn an ordinary day into the highlight of the trip.
Travel light, keep your camera ready, and talk to the locals. The people who run the motels, diners, and museums along Route 66 are keepers of its history, and their stories are often the best part of the journey.
Conclusion: Why Route 66 History Still Matters
Route 66 history is American history in miniature: ambition, hardship, prosperity, decline, and rebirth. The Mother Road carried farmers fleeing dust storms, soldiers coming home from war, and families chasing summer vacations. It built towns, inspired songs, and taught a nation to love the open road.
Though the highway no longer appears on official maps, its spirit endures in every neon sign, every roadside diner, and every road tripper who sets out from Chicago with California on the horizon.
