On highway 85 near Cupertino a few years ago they did something called “microgrooving” and it made a huge difference in tire noise, even inside your car. It’s dramatically quieter when you suddenly hit that section.

What also helps immensely both in noise and road wear is that no trucks are allowed on 85.
They also designed in sound-absorbing walls.
I couldn't find reference to this technique could you go into more detail please ?
