Welcome to the official website for the National I-73/I-74/I-75 Corridor Association! Interstate 73/74/75 is gaining support everyday, and we’re excited to be part of a project that will change lives and save lives.
Interstate 73/74/75 will bring progress and growth to all six states along the corridor: Michigan, Ohio, West Virginia, Virginia, North Carolina, and South Carolina. It will also serve as a safe alternative to other highways, and provide coastal regions with a hurricane evacuation route.
