Where Does Interstate 81 Start And End: A Route Overview

“Is Route 81 Connected to Canada?

Route 81, a major interstate highway spanning five states (Virginia, West Virginia, Maryland, Pennsylvania, and New York), boasts an impressive network of 90 interchanges. Among these, it establishes crucial connections with several other significant highways such as I-66, I-64, I-581, I-77, and I-381. While it serves as a vital transportation artery for the United States, particularly as one of the top eight trucking routes in the country, it’s important to clarify that Route 81 does not directly lead to Canada. Instead, it primarily facilitates the movement of goods and people between the southern economic hubs and the northeastern markets within the U.S.”
