The Extraterrestrial Highway is the popular name for Nevada State Route 375, a 98-mile (158 km) stretch of highway running from State Route 318 at Crystal Springs to U.S. Route 6 at Warm Springs, so named for its proximity to Area 51 and its long-standing reputation for UFO sightings.
Origins of the sightings
The area's association with unexplained aerial activity predates the highway's official name by decades. Ranchers near Groom Lake reported silver discs in the sky as early as the 1950s, around the same period Lockheed's U-2 spy plane began flying above 60,000 feet from the nearby Area 51 facility — altitudes far beyond any civilian or conventional military aircraft of the time. The U-2's unpainted silver skin, catching sunlight during evening flights, gave it a glowing "fiery" appearance from below, and similar patterns of sightings followed the introduction of the A-12 "Oxcart" reconnaissance aircraft in the 1960s. The road runs alongside the Nellis Air Force Range, and travellers along the route can still regularly hear the sonic booms of military aircraft overhead.
Official designation
Following Bob Lazar's widely publicised 1989 claims of reverse-engineering alien spacecraft at a facility near Area 51, a steady flow of UFO enthusiasts began travelling to the Tikaboo Valley area along SR 375 hoping to witness something unexplained. Recognising the tourism potential, Nevada officially designated the route the "Extraterrestrial Highway" in 1996, unveiled at a dedication ceremony that drew press, scientists, sceptics, and believers alike, complete with an "alien parade" featuring silver balloons, green masks, and mock spacecraft. A widely circulated photograph from the event shows the state governor holding up a "Speed Limit Warp 7" sign; according to local accounts, an actual sign of this kind was installed the day of the ceremony but removed by the following day and never displayed permanently.
Rachel and the Little A'Le'Inn
The only settlement along the highway is Rachel, Nevada, a small desert community home to the Little A'Le'Inn, a restaurant, bar, and motel that has become the highway's best-known stop for UFO tourists, alongside the nearby Alien Research Center gift shop. The town, with a population in the low dozens, is named after Rachel Jones, the first child born there, who died at the age of three in 1977.
Continuing sightings
The highway is often described as reporting more UFO sightings than any other road in the United States, with some estimates suggesting two to three reported sightings occur along the route each week. A roadside mailbox that became a popular gathering point for UFO watchers was eventually removed by its owner due to repeated vandalism. As with Area 51 itself, sceptics attribute the great majority of sightings along the highway to ordinary aircraft activity connected with the adjoining military range, rather than anything extraterrestrial.
