I have no idea where the gasoline tax revenues in your state go, but in my state (which happens to have one of the lowest fuel tax rates in the U.S.) all fuel taxes are allocated for the following purposes: 1) capital costs for new transportation projects (highway and mass transit); and 2) paying off existing bonds for previous transportation projects.
In my state (which may be typical), fuel tax revenues are NOT used for roadway maintenance. These come out of the general treasury, not the transportation trust find that is supported by the fuel taxes.
In many states, a portion of the fuel tax may also be directed into the general treasury. If that's the case in your state, then your first order of business should be to put an end to this practice. Even the Federal government does not do this anymore (since the mid-1990s).
The state that I live in does not even provide an itemized budget so it's impossible to see where any money is spent. Since the state is run by Dems I don't expect that to change.
