In the US, fuel taxes and tolls combined only cover about 35% of the cost of building and maintaining roads. The rest of the cost is covered by the federal, state and local governments.

That's because gas taxes are an unusually live wire in US politics, not because roads are fundamentally uneconomic. Until 2008 gas taxes did cover highway spending, and they now require general transfers because gas taxes weren't indexed to inflation. According to this website the taxes weren't increased since 1993, so in practice the US system has been deliberately starved of sustainable revenue.

"Congress could pay for projected highway and mass transit spending by simply raising the federal tax rate on gasoline and diesel fuel. Increasing those rates by 15 cents per gallon along with indexing the rates for inflation would increase federal revenues by $240 billion over ten years (CBO 2022)."

Balancing the highway books in the USA would be easy, and it's done already in most other parts of the world.
