What Is Route 66?
Route 66 is a historic U.S. highway commissioned on November 11, 1926. It originally stretched 2,448 miles from Chicago to Los Angeles and served as the primary corridor for westward migration during the Dust Bowl era of the 1930s. Route 66 earned 2 nicknames: “The Main Street of America” and “The Mother Road,” coined by John Steinbeck in his 1939 novel, The Grapes of Wrath. For context, see our previous guide on Waimea Canyon Tour: 5 Tour Types, 4 Lookouts, 6 Hikes, and a Complete Visitor Guide.
Route 66 was officially decommissioned in 1985 after the Interstate Highway System replaced it section by section. It is now designated Historic Route 66. Travelers navigate state-marked alternate alignments and sections preserved through small towns bypassed by the interstates.
Where Does Route 66 Start and End?
Route 66 starts at Adams Street and Michigan Avenue in Chicago, Illinois, and ends at the Santa Monica Pier in Santa Monica, California. Most travelers drive west from Chicago to Santa Monica. The route can also be driven east from Santa Monica to Chicago.
The midpoint of Route 66 is in Adrian, Texas, located exactly 1,139 miles from both endpoints.

Donald Reeves writes about Everglades City the way the place deserves to be written about: without the brochure language, without the manufactured wonder, and without pretending that a town of 400 people sitting at the edge of a swamp is something it is not.
He has spent considerable time in Collier County’s oldest settlement, arriving during stone crab season when the waterfront smells of brine and work, and returning in the off-season when the tourists are gone and the town goes quiet in the particular way that only genuinely remote places can. He has paddled the mangrove tunnels of the Ten Thousand Islands, eaten at places with no hours posted on the door, and spoken at length with fishing guides who navigate these waters by memory rather than chart.
His writing on Everglades City FL covers everything from tidal fishing conditions and kayak trails to lodging, local history, and the complex past that most Florida travel content carefully avoids.
He writes to give readers the honest version.
