I believe that the subsidies are for oil production and refining in general. When the subsidy happens you don’t know how much of what you are subsidizing will end up becoming gasoline.
There are also imports to be considered. If you take the money for roads out from the production subsidies then domestic producers will be effectively paying more toward roads than foreign producers that export to the US.
Taxing gasoline to support roads does a much better job of approximating a per mile road user fee which is what would probably be the best way to do it if the overhead could be kept low.
