What Is The I-81 Improvement Program?

The I-81 Corridor Improvement Program consists of innovative, targeted improvements that will have a substantial effect on the safety and reliability of a critical portion of our nation’s infrastructure. Within Virginia, I-81 connects 30 colleges and universities, 21 cities and towns and 13 counties, and parallels the Blue Ridge Parkway, making this program critical to supporting job growth and economic vitality while reducing congestion, enhancing safety and reliability, and improving quality of life for everyone in our region. The 325-mile corridor spans three VDOT districts and also acts as a critical north-south backbone of the East Coast’s freight network. Nearly 50% of the state’s value of goods are transported along the corridor, which has the highest per capita truck volume in Virginia.

For more details on the I-81 Corridor Improvement Program and the lasting benefits it will bring to the Commonwealth of Virginia, visit our About the Program page.
