Musical Road Engineering Concepts

A local road contractor is creating a musical road using steel templates to make grooves that produce music when driven over. The project involves precision engineering to ensure the correct spacing of grooves, which affects the pitch of the sound. A 490-yard stretch of Route 66 is used for this experiment, where drivers can hear 'America the Beautiful' if they maintain a speed of 45 mph. The project receives positive feedback from classic car enthusiasts, who enjoy the unique experience of making music on the highway.
