Route 66: Chicago to Los Angeles on the Mother Road

~2,400 miles · 8 states · 7–10 days recommended · The Mother Road

Route 66 is less a road than a pilgrimage: ~2,400 miles from downtown Chicago to the Santa Monica Pier through Illinois, Missouri, Kansas, Oklahoma, Texas, New Mexico, Arizona, and California. The original highway was decommissioned in 1985, but most of it survives as drivable historic alignments running beside the interstates — neon motels, mid-century diners and all.

Breaking Up the Drive

LegDistanceDrive Time
Chicago → St. Louis300 mi~4h 30m
St. Louis → Oklahoma City500 mi~7h 30m
Oklahoma City → Albuquerque540 mi~8h
Albuquerque → Los Angeles790 mi~11h 30m

If you follow only the modern interstates (I-55, I-44, I-40), the trip is about 30 hours of driving. The historic alignments roughly double your time on the road — that's the point. A good compromise: use the interstate across the flatter stretches of Illinois and Missouri, then slow down and take the old road through Oklahoma, Texas, New Mexico, and Arizona, where the best-preserved segments and roadside attractions cluster.

State-by-State Highlights

When to Go and What It Costs

April-May and September-October avoid both the Mojave's 110°F summers and winter ice on the high plateaus (Flagstaff sits at 7,000 ft and gets real snow). Expect roughly $280 in gas at 30 MPG, plus 6-9 nights of lodging — the vintage motels in Tucumcari, Seligman, and Williams cost $70-120 and are half the experience.

Navigation tip: "Historic Route 66" is signed inconsistently. The free Route 66 Navigation apps or a paper EZ66 Guide keep you on the old alignments without constant guesswork.

Frequently Asked Questions

Does Route 66 still exist?

The highway was decommissioned in 1985, but roughly 85% of the original alignment is still drivable as state roads and frontage roads beside I-55, I-44, and I-40. Brown 'Historic Route 66' signs mark most surviving segments.

How long does Route 66 take to drive?

The purist's drive on old alignments takes 2-3 weeks. Most travelers mix historic segments with the parallel interstates and complete it comfortably in 7-10 days. Non-stop on the modern interstates it's about 30 hours — see our Chicago to LA route page.
