How good are American roads?

> Interestingly, in all cases urban roads are worse quality than rural roads, presumably because they see higher traffic than rural roads.

There's more infrastructure under urban roads. Crews come in to fix some utility, shred a section of a lane, patch it poorly with dissimilar materials, and leave.

Rural roads are often unpaved. The local authority has to come by regularly with a grade to redo things or they become unusable quickly. Overall this is by far the cheapest way to have a road, but it doesn't scale to high use and city folks demand something that makes less dust. Rural roads also includes minimum maintance roads which demand 4wd (real 4wd, many SUVs will have trouble) when the weather is nice and a winch is a must when things get rainy or snowy.

Though given his definition of quality I expect he is actually ignoring all the real rural roads and only talking about major roads which while they get less traffic than urban roads are maintained to similar standards.

Maybe area-dependent? I grew up in an extraordinarily rural area in Tennessee. Most roads were paved (asphalt). Even ones out in the middle of nowhere.

The conditions of some of the remote roads might not have been great, mind you... and some seemed "thinner" almost, maybe paved a long time ago?

I think it's a snow thing - asphalt seems to wear down really fast in rural PA, probably from freezing at nights and snow and ice, so you can't do paving as cheaply out in the mountains or so on. The county dumps gravel down once a year and let's passing traffic wear it smoother over time, but it sucks to drive on fresh.
