Interstate 40 is a critical freeway that serves regional, statewide, and national purposes. I-40 in the Triangle connects communities in Orange, Durham, Wake and Johnston counties, including the Research Triangle Park and RDU Airport, with each other and the rest of North Carolina and the nation.
I-40 is the most heavily-traveled and congested highway in the region. Our growing region will require additional investments in the I-40 corridor if the “Triangle’s Main Street” will continue to be able to provide the safe and efficient mobility needed for our economic vitality and quality of life.
