It is estimated to cost $4.4 billion with recommendation that it should be paid through tolls. Construction would begin in two phases: Phase 1 (exit 31-exit 81) would begin in 2016 with tolls starting after completion; phase 2 would begin in 2019, which covers the remainder of the interstate. With a possible 2019 start date for the tolls, NCDOT plans to install nine overhead toll collection sensors every twenty miles with additional toll collection sensors at exits before tolls (to reduce drivers from jumping off and on at each toll); main toll stations will charge twenty miles each while exit tolls will charge ten miles each. Gaps along the route, where no toll collectors are located, will allow local traffic to utilize the interstate toll free. Though the toll rates have not been established, a NCDOT report suggest charging for cars in the phase 1 section, with a much lower rate of on phase 2 sections; which would work out to be $19.20 from border to border (trucks with three axles or more will be charged more). Drivers that do not carry a toll transponder (i.e. North Carolina Quick Pass) will have their license numbers recorded by cameras and will be billed by mail, at a higher toll rate.
