Tune in, turn on

Drivers in Hungary using the new R 67 expressway link will benefit from an unusual design feature of the road once the work is complete. Those driving at a certain speed will be able to hear the melody to the song, Route 67, by local rock band Republic. This effect will be achieved due to grooves cut into the road surface, which will generate harmonic frequencies in the tyres of vehicles driving within a certain speed range when using the link.
