Musical highways use specially-designed rumble strips to cause a vibration and audible rumbling between the tires and the road’s surface.
The most famous Musical Highway is in Tijeras, New Mexico. The city of Tijeras is approximately 20 minutes east of Albuquerque.
The National Geographic Society funded the project, a coordinated effort with the New Mexico Department of Transportation.
Sadly, it's no longer the same. Reports date to 2020 of people complaining about the Musical Highway needing repair.
