Route 66 Chicago to Santa Fe: The Classic Fall Road Trip on US-66 / I-40

Route 66 from Chicago to Santa Fe covers roughly 1,540 miles and 26 hours of driving time spread across 10–12 days — the right pace to hit the neon-lit diners, mid-century motor courts, and canyon overlooks that make this the most storied road trip in the country. Fall is the best season to run it: temperatures are mild through Oklahoma and the Texas Panhandle, cottonwoods blaze gold in New Mexico, and crowds thin out after Labor Day. The original US Route 66 was decommissioned in 1985, so today’s drive stitches together surviving Historic Route 66 alignments with I-40 and a handful of state routes. We’ve mapped the stops below to keep you on the old road as much as possible.

Quick Facts

Total distance: ~1,540 miles
Total drive time: ~26 hours (spread over 10–12 days recommended)
Best season: Mid-September through early November
Number of stops: 8 major stops
Starting point: Chicago, IL (Adams Street & Michigan Avenue — the official eastern terminus)
Ending point: Santa Fe, NM (we stop here rather than continuing to Los Angeles to keep the trip manageable and distinct from published LA-focused guides)

Who This Route Is For

Ideal for first-time Route 66 drivers who want the iconic stretch without committing to a 2,400-mile coast-to-coast run
Great for couples and solo drivers in standard sedans or compact SUVs; most Historic 66 alignments handle any passenger vehicle
Not recommended for RVs over 35 ft on the narrow two-lane alignments through downtown Joplin and the older bypasses around Amarillo
Good for history and Americana enthusiasts — this segment concentrates the highest density of original roadside architecture, from the Meramec Caverns barns in Missouri to the Blue Swallow Motel in Tucumcari

Chicago, IL — Start of Route 66

Begin at the intersection of Adams Street and Michigan Avenue in the Loop, where a bronze marker designates the official eastern terminus. Gas up here — Chicago prices are predictable and you won’t find better value until central Illinois. Lou Mitchell’s Restaurant (565 W. Jackson Blvd.), open since 1923, is the traditional first-meal stop: order the Greek omelette and accept the free Milk Duds they hand out at the door. Head southwest on Historic Route 66 / IL-4 through Joliet and Pontiac, where the Route 66 Hall of Fame and Museum is worth a 45-minute stop.

Springfield, IL (~3 hrs from Chicago)

About 200 miles from Chicago via IL-4 and US-66 business alignments, Springfield is the midpoint of the Illinois leg. The Cozy Dog Drive In (2935 S. 6th St.) claims to have invented the corn dog on a stick in 1946 — a debatable but fun story, and the chili dog is legitimately good. Fill up here before continuing south; gas stations get spottier through southern Illinois. October brings mild temps in the low 60s°F and patchy fall color along the Sangamon River bottomlands.

St. Louis, MO (~1.5 hrs from Springfield)

Cross the Mississippi on the historic Chain of Rocks Bridge (pedestrian/bike only) or the more practical I-270 bridge into St. Louis. The Gateway Arch National Park is a required stop — the tram ride to the top takes about 90 minutes with queue time; book tickets online at archpark.org to avoid a wait. In the St. Louis suburb of Kirkwood, Trainwreck Saloon serves solid Missouri-style toasted ravioli. The Historic Route 66 alignment through St. Louis follows Watson Road (MO-366) southwest out of the city.

Joplin, MO (~2 hrs from St. Louis)

Follow Historic 66 through Cuba, MO (stop at the Wagon Wheel Motel, built 1934, for a photo), Rolla, and Springfield before reaching Joplin. This stretch through the Ozarks shows its best color in mid-October: oak and hickory go deep orange and rust. Joplin’s Route 66 Drive-In (now a food truck park on the original drive-in site) is a reliable dinner stop. Cross into Oklahoma on US-69 Alt, which rejoins the original 66 alignment at Quapaw.

Oklahoma City, OK (~3.5 hrs from Joplin)

The Oklahoma leg of Route 66 runs through Claremore, Sapulpa, and Stroud before hitting Oklahoma City. In Stroud, Rock Café (428 W. Main St.) has been serving truckers and road-trippers since 1939 and partially inspired the Pixar film Cars — the green chili burger is worth the stop. Oklahoma City itself offers the National Route 66 Museum satellite exhibits and the excellent Cattlemen’s Steakhouse in the Stockyards District for dinner. Fill up in OKC before heading west; the Texas Panhandle has long gaps between reliable stations, especially at night.

Amarillo, TX (~4 hrs from Oklahoma City)

US-66 / I-40 crosses the Texas Panhandle on a long, flat run through Shamrock and McLean. Shamrock’s U-Drop Inn (a.k.a. Conoco Tower Station, built 1936) is the most photogenic Art Deco gas station on the entire route — stop for the photo even if you don’t need fuel. In Amarillo, Cadillac Ranch (I-40 frontage road, free, open sunrise to sunset) is the obligatory spray-paint-your-own-Cadillac experience. Big Texan Steak Ranch (7701 I-40 E) is touristy but the 72-oz. steak challenge is genuinely entertaining to watch. October weather in the Panhandle can shift fast — northers drop temps 30°F in hours; keep a jacket accessible. Wind gusts regularly hit 40–50 mph on open stretches; high-profile vehicles should check TXDOT road alerts before departing.

Tucumcari, NM (~1.5 hrs from Amarillo)

Cross into New Mexico on I-40 and exit onto Historic Route 66 at Tucumcari. This town has the highest concentration of intact mid-century neon signs per capita on the route. The Blue Swallow Motel (815 E. Rte. 66) has been operating continuously since 1939; book a room here if you want one authentic overnight stay on original 66. Kix on 66 (1102 E. Rte. 66) serves reliable green chile enchiladas. Gas up in Tucumcari — the stretch toward Santa Fe via I-25 has fewer options and prices climb near Albuquerque.

Santa Fe, NM (~2.5 hrs from Tucumcari)

From Tucumcari, take I-40 west to Albuquerque, then pick up I-25 north for the final run to Santa Fe. The Sandia Mountains east of Albuquerque are reliably golden with aspen and cottonwood color in mid-October — a strong payoff after the flat Texas miles. Santa Fe’s Plaza is the natural endpoint: park near the New Mexico History Museum and walk the adobe streets. Dinner at The Shed (113½ E. Palace Ave.), a Route 66-era institution serving red and green chile since 1953, is the right way to end the drive. The Albuquerque International Balloon Fiesta typically runs the first two weeks of October; if your timing overlaps, plan for heavy I-25 traffic and book lodging months in advance.

FAQ

How long does it take to drive Route 66 from Chicago to Santa Fe?

Pure driving time is approximately 26 hours over roughly 1,540 miles. We recommend 10–12 days to allow meaningful time at each stop. Rushing it in under 7 days means skipping most of what makes the route worth driving.

Is Historic Route 66 safe to drive in October?

The vast majority of the route is safe and well-maintained in October. The main hazards are sudden weather changes in the Texas Panhandle (high winds, fast-moving cold fronts) and isolated two-lane segments in rural Oklahoma where cell coverage is poor. Carry a physical paper map as backup and keep your tank above half in remote stretches.

Do you need a permit to drive Route 66?

No permit is required to drive any portion of Historic Route 66. Some specific attractions along the route — like certain sections of Petrified Forest National Park in Arizona, if you extend the trip — require a paid entry fee, but the road itself is public.

What is the best time of year to drive Route 66?

September through early November is optimal for the Chicago-to-Santa Fe segment. Temperatures are comfortable (50–75°F across most of the route), summer crowds have cleared, and New Mexico’s cottonwood and aspen color peaks in mid-October. Avoid July–August for the Oklahoma and Texas segments; heat regularly exceeds 100°F.

Where are the longest stretches without gas on this route?

The most exposed stretch is between Shamrock, TX and Amarillo, TX on I-40 — about 100 miles with limited services at night. A second gap runs from Tucumcari, NM toward Albuquerque. Fill up in Shamrock and Tucumcari before each of these legs. In Oklahoma, the rural segments between Clinton and Elk City can also be sparse.

Can you drive Route 66 in a standard sedan or do you need an SUV?

A standard sedan handles every section of this Chicago-to-Santa Fe route without issue. Some unpaved frontage road alignments in rural New Mexico exist but are easily bypassed on I-40. An SUV or AWD vehicle adds comfort on gravel pull-offs and is useful if you plan to explore side roads, but is not required.
