Musical Highway

Update: Sadly, the road has been repaved and that the signs for the musical highway have been removed. A quarter-mile section of this highway plays America the Beautiful if the driver goes at exactly the speed limit - 45 mph. A marvel in engineering, this road piano was achieved in 2014 with a little bit of physics, intricate mathematics, and many rumble strips (those bumpy thingies that alert you when you stray from your lane). It's also a great way to encourage safe driving speeds!
