RV route guide
Route 66 — western section (Albuquerque to Santa Monica)
The most intact RV-driveable Route 66 segment. Where the Mother Road still feels like itself.
Route 66 was decommissioned as a US highway in 1985. Substantial fragments survive in driveable form, particularly through New Mexico, Arizona, and California. The western section — Albuquerque to Santa Monica — has the densest concentration of preserved alignment, intact roadside architecture, and continuous business history. For RV travelers, the western Route 66 is a multi-day immersion in mid-century American highway culture.

Is Route 66 a single road today?
No — Route 66 was decommissioned in 1985 and is now a discontinuous patchwork of state and local roads. The most intact RV-driveable segments are: New Mexico (Tucumcari to Gallup via NM-117 and old US-66), Arizona (Holbrook to Kingman via I-40 service roads and AZ-66), California (Needles to Barstow via National Trails Highway, Barstow to Santa Monica via various). I-40 closely parallels the historic alignment through New Mexico, Arizona, and into California — modern I-40 + Route 66 service-road exits is the practical multi-day drive.
- Not a single road today — decommissioned 1985
- Western section has best-preserved alignment
- I-40 parallels alignment through NM, AZ
- AZ-66 segment Seligman to Kingman is iconic intact
- RV-friendly throughout the western route

What Route 66 tourism + nostalgic blogs doesn't tell you
Route 66 nostalgia coverage often glosses over the fact that the road is no longer continuous. Honest framing for RV travelers: this is a curated set of fragments, not a single drive.
What's underdiscussed: Indigenous communities along the route. The Navajo and Hopi nations have significant presence along the route in northeastern Arizona. The Native American trading post culture preserved along Route 66 is a complex history worth engaging with critically — not just as nostalgia.
