Per mile, small urban roads were millions of usd a mile (see department of transports annual report and it varies by region). Maintenance is even worse. It’s the 5th highest expense for most cities (US census survey of local and state governments 2020).

Of course the suburbs don’t make sense, you have a half mile of road out to a neighborhood and another half mile of street in the neighborhood itself. The percentage of property taxes going to the road is probably just a few percent points. With only a few hundred houses, it would take decades to raise the 1-3 million to replace the road.

And without use from heavy trucks and huge volumes from city traffic, the roads in suburbs last for decades, what's your point?

Already have this problem with our subdivision lol. Private road, and replacing the road is going to be $20k a house even over 20 years or something even with a bond lol, and that’s a normal, reasonable-density subdivision. People don’t realize how much rural and suburban roads are getting subsidized.
