Also depends on where you're looking. Cities will have worse roads because they're always digging working on gas and water lines, some of which leak. That disturbance of the ground will make things a lot worse than some rural road where the ground hasn't been disturbed since it was created.
The new suburb I live in they put all that beside the road not under it. That is what the space between the road and sidewalk is for.
This is the truth. They’re digging out under a massive overpass in my area right now to fix water main and gas piping issues as we speak.
Road is all torn up and patched up. It has been a boondoggle of construction cones and heavy machinery for months now.
