I wonder what the numbers are like in west EU as a comparison.

That would be an interesting question. My experience is that there's a lot more chip seal on smaller roads as a refurbishment (tar + a thin layer of gravel) rather than hot asphalt paving. It's a lot cheaper, but doesn't last as long. Motorways in France and Germany seem to be repaved more often, and billiard table smooth in a lot of cases.

  France has private-ish roads that are quite expensive. So does italy, there you have to often literally pay a human everytime you get of the highway. This leads to many people driving on small roads, polluting and wearing down those roads. Not sure about Germany, but they just have a super strong car lobby in general, and its one of their national pride things, so they tend to find money for that. Here in Switzerland we have a very high gas price, but that leads to many people going for gas outside of Switzerland and we have no idea what to do when EVy really take off. The true cost of those roads is hidden in the 'normality' of the high gas prices. Roads are a tricky problem, not just for libertarians.

In Germany, a km of Autobahn costs ~10M € which is around 16M €/mile [0]. An Autobahn built in/towards a city tend to get way more expensive.

The rule of thumb in Western EU (mind you it is only an order of magnitude and may vary) for a 10 meter wide road (think one way highway two lanes+emergency lane 2x3.75+2.50=10 or an extraurban road 2x3.50+2x1.50=10) is usually considered: plain road (on terrain) € 10,000,000 x km viaduct/bridges € 20,000,000 x km tunnel € 30,000,000 x km with a variation of up to -15% or -20% in countries where workmanship and materials are cheaper and + 15% or + 20% in the more expensive ones.
