Our state gasoline tax is supposed to go for road building and repair. Some years back, I read that it was dumped into the "General Fund" as a lot of other taxes passed for specific purposes were.
That's the problem with most politicians---they forget about the promises they made when levying new taxes.
I, for one am totally opposed to toll roads and will go miles out of my way to avoid them, on principle.
The traffic lights on the feeder are deliberately out of phase to cause congestion so that even with toll gate stack ups, the toll road will always get you down the road faster than using the feeder. Congestion by design. The civil engineers intentionally cause road rage and aggravation.
If you get over to some of the roads parallel to the feeder roads, you can travel much quicker.
Our government doesn't work to solve the traffic problem, it works to control the traffic and keep revenue coming in (tolls, speeding tickets, red light tickets...).
