Route 66: Why America's Mother Road Was Decommissioned in 1985 & Its Enduring Legacy


27 juin 2025

On June 27, 1985, a significant chapter in American history closed as the legendary Route 66 was officially removed from the nation's highway system maps. Yet, four decades later, it remains a cinematic icon. From The Grapes of Wrath to Cars, this road is more than just a route; it's a legendary backdrop, a character in its own right on the big screen. For filmmakers, it embodies the American epic, bridging dreams and disillusionment.

The decommissioning of Route 66 in 1985 was the culmination of decades of transformation in the American road landscape, primarily driven by the rise of the Interstate Highway System. Starting in the 1950s, under the impetus of the Federal-Aid Highway Act of 1956, the U.S. embarked on building a vast network of modern expressways. These new roads, faster, more direct, and safer, aimed to facilitate commerce, national defense, and civilian travel. For a deeper dive into the history of this system, you can explore the resources of the Federal Highway Administration (FHWA). Gradually, these Interstates, such as Interstate 40 (I-40), I-55, I-44, I-15, and I-70, paralleled and replaced sections of Route 66 across most of its path. Whenever a new Interstate segment was completed, rendering a portion of Route 66 obsolete, that section was progressively removed from the U.S. Highways system. June 27, 1985, marked the finalization of this process, with the last bypassed section in Arizona being designated, signifying that Route 66 no longer existed as a continuous, official national route. For more details on its decommissioning history, you can consult reliable resources like the U.S. National Park Service on Route 66.

An Unforgettable Cinematic Canvas

As early as 1940, John Ford set his camera on Route 66 to adapt The Grapes of Wrath. The film, based on John Steinbeck's novel, immortalized this road as a path of exile and survival. Steinbeck famously dubbed it The Mother Road, the route through which the broken hopes of rural America traveled.

Thirty years later, Dennis Hopper and Peter Fonda took up the torch with Easy Rider, a cult road movie where motorcycles carve through the Arizona desert to Santa Monica. Route 66 then became a symbol of rebellion and psychedelic wandering.

In the 1980s, it served as a backdrop for the thriller The Hitcher and the dilapidated motel in Bagdad Cafe, which became a pilgrimage site for cinephiles in Newberry Springs. Later, Thelma & Louise, Rain Man, Forrest Gump, and Little Miss Sunshine all stopped there in their own ways, capturing the essence of the American myth.

In 2006, John Lasseter's animated masterpiece Cars achieved a true cultural miracle. More than just a film, Cars is a vibrant, well-researched, and moving tribute to Route 66. The director, passionate about the subject, surrounded himself with top historians, crisscrossed the road for months, and recreated a forgotten America with a fidelity and emotion rare in contemporary animation. The fictional town of Radiator Springs, inspired by real places like Seligman and Peach Springs, became the beating heart of the film. Through the character of Sally, the film tells the silent tragedy of small towns sacrificed by Interstate construction. Cars transforms the Interstate into an antagonist and Route 66 into the heroine of a story of rebirth.

Route 66 Today: An Adventure Still Possible

Erased from official maps but never from memory, Route 66 can still be traveled, and many will celebrate its centenary in 2026. From Chicago to Santa Monica, nearly 85% of its original alignment is preserved, dotted with iconic landmarks. These sections are often designated as "Historic Route 66." The preservation of these unique stretches is a vital effort, championed by organizations like the National Trust for Historic Preservation, which work to keep its legacy alive. For lovers of asphalt, dust, and neon signs, specialized guides abound.
