That same thing was done on a road in Antelope Valley, in the high desert north of Los Angeles, years ago for a TV commercial. Later, when it was going to be lost due to a road re-surface, they created it again on another road nearby, in the same area.
I don't know if it still exists.
edit
If you google search 'Antelope Valley musical road' you will find some You Tube hits about it. It looks like is was a 2009 Honda commercial.
