Local roads bleed money universally everywhere, because pretty much no place charges tolls for local road use. Gas taxes do not cover road costs, because gas taxes are not by the same entities that actually build the roads, so there is no reason to expect it to be the case. However, and fortunately, road construction and maintenance is universally a small part of municipality budgets in US, typically under 10%, and very rarely anywhere close to 20%, so there is not much reason to worry about affordability of local roads.
