Why are bridges so loud?

While the physics of grooves and wheels making a sound is the same, the purpose of grooving bridges is to reduce hydroplanning and other water related hazards. Due to the proximity of water and higher relative humidity, the probability of condensation on bridges is higher.

Why do some highways sound different?

Tires and pavements both contribute to road noise. Tires without tread can be very quiet. Those with simple geometries can be modestly louder, but those with large, blocky tread patterns are among the loudest. But the texture wavelengths responsible for a rough or a noisy ride are different.
