Even though since May 2003 the US Route 666 is officially known as US Route 393 or 491, the legend of "the Devil's Road" or "the Devil's Highway" (Camino del Diablo), will always be remembered. According to local statistics, the highway has bad reputation because of a very high percentage of road accidents, and they know that some of the reasons why this is happening. The original name of the highway had absolutely nothing to do with Antichrist or the number of the beast (666), as mentioned in Revelation, the last book of the Bible. The road was the sixth branch of an interstate route that was known as US 60. The section which connects Chicago to Los Angeles eventually became the legendary highway of Route 66. Four Corners and the detour from the Route 66 became 666 in August 1926. However some say that naming the highway with 666 only bring bad luck. The 190 miles of former US Route 666 begins in Gallup, New Mexico, stretch it's way through 70 miles of Colorado, and ends in Monticello, Utah.
Based on several witnesses, one night of full moon, there was a black, vintage 1930 Pierce-Arrow Roadster has appeared and suddenly disappeared and dozens of cars, trucks, motorcycles will have an accident after the phantom car sighting and so far the phantom car is connected to at least five deaths.
Dr. Avery Teicher from Phoenix over the past ten years documenting the reports of the phantom car and researching the relationship between the Phantom Pierce-Arrow and the Hellhounds that materialize to scare anyone who stop their vehicles at Route 666. According to Dr. Teicher, two members of a motorcycle gang, had their two arms eaten by phantom dogs, while the third gang member, had 90% of his face chewed off. Also several eyewitnesses reporting from the US Route 666 there is a phantom women hitchhiker which disappears immediately when someone give a ride to her.
On January 21, 2003, with support from the New Mexico governor, Bill Richardson stated that he will change the name of the US Route 666. And finally it became official in May 2003.
