what is route 66: What Does It Mean?
Route 66 refers to the historic U.S. Route 66, the highway that once linked Chicago to Santa Monica, spanning about 2,448 miles. More than a pavement corridor, it became shorthand for road travel, freedom, and the changing American economy.
Ask someone to describe Route 66 and they might mention neon signs, roadside diners, jukeboxes, and families moving west. The name evokes a period when highways knit the country together and travel was an act of discovery.
Etymology and Origin of Route 66
The name Route 66 came from the U.S. highway numbering system adopted in 1926. Number 66 was assigned because it fell between other major east-west routes and because even numbers run east-west in that system.
U.S. Route 66 was commissioned in 1926 and gradually improved during the 1930s and 1940s. It helped move agricultural goods, migrants, and tourists, and it grew into a cultural phenomenon after World War II.
How Route 66 Is Used in Everyday Language
People use the phrase Route 66 in several ways. Sometimes it is literal, referring to a segment of road you can still drive. Other times it is symbolic, a metaphor for taking the scenic or nostalgic path rather than the fastest route.
“We drove a chunk of Route 66 last summer and stopped at every diner we could find.”
