The Original 1926 Alignment Through New Mexico's Highlands

When Route 66 was commissioned on November 11, 1926, it took a curious northward jog into the New Mexico highlands, climbing from Albuquerque north to Santa Fe before swinging east through the mountain passes to Las Vegas and Tucumcari. This was a political route, lobbied for by New Mexico Governor Arthur Hannett to send national traffic through the state capital. Hannett's successor was less enamored of the deal, and on June 27, 1937, the highway was straightened: Route 66 was rerouted across central New Mexico through Moriarty and Edgewood, bypassing Santa Fe entirely. The Santa Fe loop survived only 11 years on the official map, but those 11 years are why this 175-mile drive exists. The pre-1937 alignment from Santa Fe to Tucumcari is the most historically rich and least-traveled stretch of Route 66 in New Mexico, threading through Glorieta Pass (where the Civil War's "Gettysburg of the West" was fought in March 1862), past the 1,000-year-old Pecos Pueblo ruins, through the haunting Old West town of Las Vegas (where Teddy Roosevelt assembled the Rough Riders), out across the Llano Estacado, and finally arriving in Tucumcari, the neon-lit Route 66 motor-court town that markets itself with the legendary 1930s slogan "Tucumcari Tonite." The drive passes through 2026, the centennial year of Route 66, on its way through landscapes that look much as they did when the road was new: the southern Sangre de Cristo Mountains, the Pecos River valley, the grasslands of the Llano Estacado, and an ever-changing horizon of mesas, sandstone bluffs, and prairie sky.

Key Stops

Santa Fe The oldest state capital in the United States (founded by Spanish colonizers in 1610) and the highest at 7,199 feet. Original 1926 Route 66 entered Santa Fe from the south on what is now Cerrillos Road, passed through the Plaza area (where it briefly ran on streets including College Street, Don Gaspar, Water Street, and Old Santa Fe Trail), and exited northeast toward Las Vegas via the old Santa Fe Trail. Key stops:

• Santa Fe Plaza (the heart of the city since 1610, anchored by the Palace of the Governors, the oldest continuously occupied public building in the United States)
• Cathedral Basilica of St. Francis of Assisi (1869–1886, just east of the Plaza)
• New Mexico Museum of Art and the New Mexico History Museum (Plaza area)
• Loretto Chapel with its mysterious "Miraculous Staircase"
• Canyon Road, the gallery district with over 100 art galleries packed into half a mile
• Georgia O'Keeffe Museum (the world's largest collection of her work)

Full services and the most extensive lodging options on the drive. Take time to wander; Santa Fe is its own destination.

Old Pecos Trail / Old Las Vegas Highway Leaving Santa Fe, the original Route 66 alignment followed what is now Old Pecos Trail and then Old Las Vegas Highway, paralleling I-25 east. The two-lane frontage road preserves some of the original 1920s pavement and is far more interesting than the interstate.

Glorieta Pass The road climbs to Glorieta Pass at 7,500 feet, where on March 26–28, 1862, Union forces ambushed and destroyed the Confederate supply train, ending the Confederate invasion of the New Mexico Territory and any Confederate aspirations to capture California gold. Called the "Gettysburg of the West," the battle preserved the Southwest for the Union. Interpretive panels at the Glorieta Battlefield (part of Pecos National Historical Park) explain the engagement.

Pecos National Historical Park Just off the original Route 66 alignment, this remarkable site preserves the ruins of Pecos Pueblo, once one of the largest Ancestral Puebloan trading centers in the Southwest, with a population estimated at over 2,000 at its peak in the 15th century. A self-guided 1.25-mile loop trail visits the multi-story pueblo ruins, two excavated kivas you can descend into via wooden ladders, and the massive ruins of the Spanish mission church built in 1620 (destroyed in the 1680 Pueblo Revolt) and rebuilt around 1717 (the walls still rise dramatically against the sky). The park also includes the Glorieta Battlefield and the Forked Lightning Ranch, home to E. E. "Tex" Austin (rodeo promoter and inventor of rodeo as a spectator sport) and later movie star Greer Garson. Entry is free. Visitor center open daily; allow 2 to 3 hours.

San Jose, Tecolote, and Bernal Tiny villages along the pre-1937 alignment, each with adobe churches, working ranches, and a handful of houses. The Pecos River valley opens here into broad meadows. NM-3 and NM-50 closely follow or coincide with the historic road.

Las Vegas, New Mexico Not to be confused with Las Vegas, Nevada, this Las Vegas (founded 1835) was once the largest city between Independence, Missouri, and San Francisco, a major stop on the Santa Fe Trail and a railroad boomtown. Over 900 buildings are listed on the National Register of Historic Places, giving Las Vegas one of the largest concentrations of historic buildings of any city in the United States. Key stops:

• Old Town Plaza (the original 1835 Mexican town plaza, with the Plaza Hotel built 1882, where Teddy Roosevelt assembled his Rough Riders in 1898 before they shipped out for Cuba and the Spanish-American War)
• Castañeda Hotel (a 1899 Harvey House along the Santa Fe Railway, restored in 2019 by hotelier Allan Affeldt; a magnificent restoration of one of the original Fred Harvey lodges that helped invent American hospitality)
• Carnegie Library (1904, one of the country's last working Carnegie libraries)
• City of Las Vegas Museum and Rough Rider Memorial Collection

The town has been a favored film location since the silent era. Scenes from Easy Rider (1969), No Country for Old Men (2007), True Grit (2010), Outer Range (2022), and many westerns were filmed here. The Plaza Hotel still operates; the Castañeda Hotel reopened as a hotel and restaurant in 2019.

Romeroville Just south of Las Vegas, the tiny community of Romeroville marks the spot where pre-1937 Route 66 turned east toward Santa Rosa and Tucumcari. The original 1879 Romeroville mansion of Trinidad Romero, a Hispanic territorial delegate to Congress, once stood here; it burned in 1932 and only foundations remain.

Santa Rosa At the junction of I-40 and US-54, Santa Rosa is the natural midpoint of this drive and offers two of the most distinctive Route 66 stops in New Mexico:

• Blue Hole: An artesian-fed natural pool 80 feet wide and 80 feet deep, with crystal-clear blue water at a constant 62°F year-round. The pool's surface stays calm even though 3,000 gallons per minute flow continuously through the spring. Popular with scuba divers from across the Southwest (technical divers can explore connected underwater cave systems with permit). Free for swimming; small fee for diving permits.
• Route 66 Auto Museum: A small but excellent museum with restored 1940s and 1950s cars, classic gas pumps, and Route 66 memorabilia, all in an authentically restored garage.

Santa Rosa also has a handful of vintage motels and the Park Lake city pool. The town is on both the pre-1937 (north) and post-1937 (south) Route 66 alignments, marking where the two reunite.

Cuervo (Ghost Town) About 20 miles east of Santa Rosa, the abandoned ranching town of Cuervo sits split in half by I-40, its weathered adobes, a stone church, and a small cemetery visible from the interstate. A photogenic stop for ghost-town enthusiasts.

Tucumcari The drive's eastern terminus and arguably the best-preserved Route 66 town in America. Tucumcari sits on the Llano Estacado at the foot of Tucumcari Mountain (named "by lookout" in Comanche). The town's classic 1939 slogan "Tucumcari Tonite!" was painted on billboards from Amarillo to Albuquerque promising "2,000 Rooms" to lure weary motorists, and the legacy is alive today in some of the finest preserved Route 66 motels in America:

• Blue Swallow Motel (built 1939, "100% Refrigerated Air" promised in 1942, beautifully restored, possibly the most photographed motel on Route 66). Each room has a private garage with original neon signage above. National Trust for Historic Preservation property.
• Tee Pee Curios (1944, with a giant concrete teepee out front, neon arrow signs, and a packed-to-the-rafters shop of Route 66 souvenirs and Western kitsch)
• Motel Safari (1959, restored by film actor Richard Talley)
• Roadrunner Lodge (1964, restored)
• Tucumcari Murals: Over 35 large-scale murals around town depict Tucumcari history, Route 66 culture, and Native American heritage
• Route 66 Photo Museum and New Mexico Route 66 Museum

Full services; lodging here is part of the experience. Reserve the Blue Swallow well in advance for centennial-year stays.

Driving Tips

• 2026 is the Route 66 Centennial. The Mother Road was commissioned on November 11, 1926. New Mexico is hosting numerous anniversary events through the year; Tucumcari, Santa Rosa, and Las Vegas (NM) are particularly active. Book lodging well in advance, especially around the November 11 anniversary.
• This drive follows the pre-1937 alignment of Route 66. The post-1937 alignment (Santa Rosa west through Moriarty to Albuquerque on I-40) is a different drive entirely. If you want to see both, plan a loop through Albuquerque.
• The roads are paved throughout, easy driving for any vehicle. The Old Las Vegas Highway from Santa Fe parallels I-25 and is the most authentic original Route 66 driving experience on the western half.
• Allow time at each town. Las Vegas (NM) alone deserves several hours; the historic plaza, Castañeda Hotel restoration, and museums reward slow exploration.
• Fuel up in Santa Fe, Las Vegas, Santa Rosa, and Tucumcari. The stretches between can run 50 to 60 miles with limited services.
• Cell coverage is reliable along I-25 and I-40 but spotty on the older alignments through small villages. Download offline maps.
• Summer afternoon thunderstorms can be intense on the Llano Estacado. Lightning is a real hazard on open prairie; if storms develop, stay in your vehicle and avoid stepping out onto open ground.
• Watch for wildlife and livestock on the older alignments, particularly in the open-range sections near Las Vegas (NM) and east of Santa Rosa.
• Pecos National Historical Park is free; the cliff-pueblo tour requires advance ranger-guided access (call ahead).
• The Blue Swallow Motel, the Castañeda Hotel, and the Plaza Hotel (Las Vegas) often book months in advance, especially for centennial events. Reserve as early as possible.
