The project will also improve the N.C. 86 exit and sections of that highway for several hundred feet both north and south of the interchange.

Once completed this project will improve traffic flow along the I-40 corridor and help relieve heavy congestion that develops during peak hour times. The project utilizes environmentally friendly recycling of existing concrete pavement into sub-base material for new lanes. Work is anticipated to begin in the fall of 2022 and the job is expected to be completed by the fall of 2025.
