Origins & Early History
Originally designated in 1926, U.S. Route 666 earned its infamous nickname, “The Devil’s Highway,” thanks to its association with the number 666 from biblical prophecy. The road cut through New Mexico, Arizona, Colorado, and Utah—arid, isolated, and mysterious. Early on, it gained notoriety for high accident rates and strange reports from travelers.
Paranormal Phenomena
Many report phantom vehicles appearing and vanishing in mirrors, or being chased by a demonic semi-truck that seems determined to run them off the road. Other common encounters include packs of hellhounds, glowing-eyed dogs sprinting alongside vehicles. UFO sightings are also a regular part of the lore, as well as strange lights and shadowy figures walking the highway at night.
Cultural Impact
The eerie vibe was so intense that highway signs were repeatedly stolen by souvenir hunters. In 2003, authorities renamed it U.S. Route 491 to defuse the stigma. Still, the legend persists. Paranormal investigators, thrill-seekers, and supernatural fans continue to explore the desolate stretch, cementing its place as one of the Southwest's most enduring urban legends.
