Program Overview

The I-81 Corridor Improvement Program is innovative, targeted improvements that will have a substantial effect on the safety and reliability of a critical portion of our nation's infrastructure.

As a critical north-south backbone of the East Coast’s freight network, the I-81 corridor is vital to the efficient movement of goods through Virginia. More than one-third of all trucks and nearly 50% of the state’s value of goods are transported along the 325-mile corridor. I-81 has the highest per capita truck volume in Virginia.

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.
