Interstate 81 Multistate Corridor Study

January 2013

The I-81 corridor is an economic engine for the six states it traverses – Tennessee, Virginia, West Virginia, Maryland, Pennsylvania, and New York – as well as for the rest of the country. It provides direct freight services to these states, and also functions as a leading through-freight corridor for the eastern U.S. I-81 is a key freight alternative to I-95, the Nation’s most congested freight corridor. It is also the most direct connection between southeastern and south central U.S. states and the population centers of the northeast.
