National I-73 / I-74 / I-75 Association
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.

S.C. Gov. McMaster Calls for Expansion of I-73 in S.C.
On Oct. 4, 2021, S.C. Gov. Henry McMaster, S.C. Dept. of Transportation Sec. Christy Hall, members of the General Assembly, and local Horry County elected officials gathered at the Myrtle Beach Area Chamber of Commerce to call for the expansion of Interstate 73 in South Carolina. The governor’s proposed $300 million investment would be funded through a combination of South Carolina's share of American Rescue Plan Act (ARPA) dollars and non-recurring dollars from the state's projected $1 billion budget surplus for the fiscal year 2022.
