Route 66 Turns 100: The Highway That Became America’s Mother Road

A century ago, a new highway designation helped change how Americans traveled, worked, and explored their country.

On November 11, 1926, U.S. Route 66 officially became part of the nation’s developing highway system. Stretching about 2,400 miles from Chicago to Los Angeles, the road became one of the most recognizable highways in American history.

Known as the “Mother Road” and the “Main Street of America,” Route 66 connected cities, small towns, and rural communities across eight states: Illinois, Missouri, Kansas, Oklahoma, Texas, New Mexico, Arizona, and California.

What began as a practical transportation route eventually became a symbol of freedom, adventure, and the American dream.

Connecting a Growing Nation

When Route 66 was established, automobile travel was becoming increasingly popular, but long-distance driving remained difficult.

Roads were often poorly maintained, and many rural communities had limited connections to major transportation routes.

Rather than constructing an entirely new highway, officials connected existing roads into a continuous route between the Midwest and the West Coast.

The highway was not completely paved until 1938.

As more Americans purchased automobiles, Route 66 became an important link for travelers, truck drivers, and businesses.

Small towns along the highway benefited from the growing traffic. Gas stations, diners, motels, repair shops, and roadside attractions began appearing to serve travelers.

For many communities, Route 66 became an economic lifeline.

The Road to a Better Life

During the Great Depression and the Dust Bowl of the 1930s, Route 66 took on another meaning.

Families devastated by drought, failed crops, and economic hardship traveled west in search of work and a fresh start.

Many followed Route 66 toward California, hoping to find opportunities that had disappeared in their hometowns.

Author John Steinbeck immortalized the highway in his 1939 novel The Grapes of Wrath, calling it the “Mother Road.”

The nickname captured the highway’s importance to generations of Americans who saw the open road as a path toward a better future.

An American Cultural Icon

Following World War II, Route 66 became a destination in its own right.

Families packed their cars for vacations, stopping at roadside restaurants, colorful motels, souvenir shops, and unusual attractions.

Neon signs illuminated the highway at night, while diners and service stations became familiar landmarks.

The road also found a permanent place in popular culture.

Bobby Troup wrote the song Route 66 in 1946, and recordings by Nat King Cole, Chuck Berry, and the Rolling Stones helped make the highway famous worldwide.

A television series titled Route 66, which aired from 1960 to 1964, further strengthened its association with adventure and life on the open road.

Over the years, the highway became more than a means of transportation. It represented the excitement of discovering new places and the independence that came with owning an automobile.

The Highway That Disappeared From the Map

Route 66’s importance began to decline with the construction of the Interstate Highway System in the 1950s.

Modern interstate highways offered faster, more direct routes across the country, bypassing many small communities that depended on Route 66 traffic.

As travelers moved to the interstates, some roadside businesses closed, and once-busy stretches of the highway became quiet.

In 1985, the federal government officially removed Route 66 from the highway system.

But its story did not end there.

Preservation groups, historians, business owners, and highway enthusiasts worked to protect the road’s remaining sections and historic landmarks.

Today, much of the original route is still travelable, although different portions carry new road names and highway numbers.

Historic motels, diners, filling stations, and roadside attractions continue to draw visitors who want to experience a piece of American history.

The highway’s western endpoint also changed over time. Although the original 1926 route ended in Los Angeles, it was officially extended to Santa Monica in 1936.

Celebrating 100 Years of the Mother Road

This year marks the 100th anniversary of Route 66, with celebrations taking place across the eight states connected by the historic highway.

A major centennial celebration is scheduled for November 11, 2026, in Tulsa, Oklahoma, featuring special events, music, exhibits, and activities recognizing the road’s history.

Other communities are marking the anniversary with festivals, car shows, historical programs, and preservation projects.

A century after its establishment, Route 66 still attracts travelers from around the world.

Its famous highway signs still stand along desert roads and small-town streets, reminding visitors of an earlier era of American travel.

The interstates may have replaced Route 66 as a major transportation corridor, but they never replaced its place in American culture.

One hundred years later, the Mother Road remains a symbol of exploration, opportunity, and the enduring appeal of the open highway.
