The tolls, thus, raise the revenue needed to help pay off the bonds sold to pay for the highway and its interchanges.
There are also costs for overall maintenance including road repairs, signs, mowing, and winter weather preparation and response.
The latest toll increase raises the per mile cost to 18.6 cents - eighth highest in the nation.
And while costs are rising, so are the number of drivers and number of toll transactions - from 23 million tolls paid in 2012 to 45 million in 2016.
Data from a 2017 quarterly report also shows a high of 47,720 drivers passing through the NC-540 and NC-147 interchange on an average weekday.
The report also maintains the highway remains in a "ramp up" period, where drivers are still learning about the expressway, its route, its entrances and exits, and its overall accessibility.
