Route 666, the real-life Highway to Hell, is in Kensington

Montgomery County Halloween Countdown

Did you know there is a real Route 666, and it is located in Kensington, Maryland? The Satanic-numbered Maryland highway designation was given to Armory Avenue, a portion of Howard Avenue, and St. Paul Street, when they served as the original route to cross the Baltimore & Ohio (now CSX) Railroad tracks in Kensington. Today, the newer Connecticut Avenue serves that purpose to the west, with a grade-separated bridge crossing. The controversial 666 route number was removed in 1958, but you can still drive the real-life "Highway to Hell" today. However, the only way to travel the entire length continously is on foot, by using the pedestrian crossing at the Kensington railroad station.
