A Stretch Of Route 66 Will Play "America the Beautiful" As You Drive To the Side



In 2014, the New Mexico Department of Transportation decided to spice up a particularly desolate stretch of Route 66 between Albuquerque and Tijeras by adding grooves in the road that will play music when you drive over them. If you drive the speed limit of 45 mph for the quarter-mile stretch, you can hear "America the Beautiful" play through the vibrations in your car's wheels. The grooves in the road work just like the rumble strips that vibrate your car when you start to drift out of your lane. These rumble strips, however, are precisely positioned to create different pitches when you drive over them. The engineering behind the road is pretty simple. Anything that vibrates 330 times per second will produce an E note, so the rumble strips were placed 2.4 inches apart.
