FTA:

>The problem is that the model no longer works. Over the decades, the cost of maintaining roads and highways has risen, even as cars have become more fuel-efficient. And raising gas taxes, even just in line with inflation, is generally considered to be political suicide. The last time Congress did it was in 1993. The result is a giant deficit. In fiscal 2024, the federal government spent $27bn more on maintaining roads than it collected in tax. At the state and local levels, fuel taxes covered barely a quarter of road spending.

So apparently that's how the owner intends to raise the money and build. Beyond that, "who should pay for government spending" is of course the perennial discussion, and exactly what we are debating right now.
