Overview

1. Introduction

Route 66 (U.S. Highway 66) is one of the most celebrated arteries on the American road network. Established on November 11, 1926, it linked Chicago (Illinois) to Santa Monica (California) across roughly 2,448 miles, eight states, and three time zones. Nicknamed the Mother Road by John Steinbeck, it fed the Main Streets of Midwestern towns, Great Plains communities, and Southwest outposts before reaching the Pacific.

Fully paved by 1938, it became the highway of the Dust Bowl exodus, then the symbol of the 1950s-1960s American road trip. The Interstate system gradually replaced it; on June 27, 1985, it was removed from the federal U.S. Highway System. Since then, a revival led by local associations (including Angel Delgadillo in Seligman in 1987) has turned the Mother Road into a major heritage and tourism route.

This guide is for travelers planning a trip or anyone curious about the road's history. It draws on the National Park Service, the Federal Highway Administration, the Library of Congress, and the tourism offices of all eight states along the corridor.

Key takeaway: Route 66 was decommissioned in 1985 and no longer appears on current federal highway signs. According to the NPS, about 85% of the historic alignment remains drivable via sections marked "Historic Route 66." Check which segments are open before you leave.

Historical context

7. History of Route 66

Established on November 11, 1926 as part of the new federal U.S. Highway System, Route 66 connected the agricultural Midwest to the Pacific Coast. Unlike the straight Interstates that followed, it ran through downtowns, fueling motels, gas stations, and mom-and-pop shops along the way. Hence its nickname, the "Main Street of America."

Fully paved by 1938, it became the first major transcontinental highway paved end to end. During the Great Depression and the Dust Bowl, thousands of families took it west toward California. After World War II, it embodied prosperous postwar America: road trips, neon diners, and themed motels.

The Interstate Highway Act (1956) launched the network that would gradually bypass Route 66. On June 27, 1985, the American Association of State Highway Officials officially removed it from the federal system. Bypassed towns declined, but a revival began in 1987 when barber Angel Delgadillo founded the Historic Route 66 Association of Arizona in Seligman.

Today the corridor is protected and promoted as a heritage route. The 2026 centennial mobilizes associations, states, and Congress through the Route 66 Centennial Commission.

Collective memory

11. Cultural impact and revival

More than a highway, Route 66 became a symbol of freedom: the open road, escape, and the search for a better life. Literature (Steinbeck, Kerouac), music (Nat King Cole, Chuck Berry, Depeche Mode), film (Easy Rider, Badlands, Cars), and television etched its myth into the global imagination, far beyond American borders.

After decommissioning in 1985, enthusiasts worldwide helped bring it back. Restored neon motels, dedicated museums (Clinton OK, Pontiac IL), festivals, and classic car clubs testify to thriving nostalgia tourism. The NPS documents the corridor as national cultural heritage.

Approaching the 2026 centennial, the Mother Road has never been more alive: marked alignments, digital guides, state-by-state events, and international visitors (including European and Francophone travelers) keep alive the legend of a road that was, and remains, America's ribbon across the continent.
