The Other Haunted Place on Route 66, and This is a Whole Road: Route 666

ROUTE 666

U.S. Route 491, formerly known as U.S. Highway 666, was known as the "Devil's Highway" because of the number and a fairly large number of fatalities along its route in New Mexico.

Some drivers have reported being chased by hellhounds -- supernatural canines that represent death in some cultures -- or seeing a ghostly semitruck on fire according to Commercial Truck Trader.
