Note that in the context of the "half came from gas taxes," the article is only talking about highway funding. Local road funding isn't covered by Fed gas taxes at all.
I don't think that's true. Gasoline taxes aren't high enough to pay for roads.

It seems as of 2015, 50% of road related costs came out of general taxes. And as gas taxes have remained fairly constant, while roads have become more expensive to repair as they get worse, I can only think that number has gone up since then.
