Once tolls are in place, the government will refuse to take them all down at a later date. Tolls are too much of a money-maker for the government, and the government will just cling to their existence like barnacles to the flesh of whales. One just has to look at the total toll situations in both New Jersey and Massachusetts to see all of the continuous problems that tolls create.
The toll booths will be taken down once the roads are falling apart.
The state will then be encouraged to pass a bond measure to finance rebuilding the roads and the whole process will repeat itself forever.
