Musical Roadway in New Mexico

Who doesn’t love to drive down the highway listening to music, especially patriotic music around the 4th of July? Well, the folks at the New Mexico Department of Transportation are helping motorists enjoy this pastime by incorporating music into the road! National Geographic’s show Crowd Control initiated the project (with funding from Allstate Insurance) to help drivers focus on the road and drive the speed limit.

The installation is similar to rumble strips, the pavement grooves that alert drivers when they are drifting out of the drive lanes and onto the roadway shoulder. However, NM DOT’s musical highway has pavement grooves placed within the drive lanes. Vehicle tires emit a sound as they pass over the grooves. This sound varies in pitch according to the groove spacing. The correct sequence of grooves and spacing cause the vehicle’s tires to emit sounds that mimic a song, in this case, a famous, well-known, patriotic song, “America the Beautiful.”
