Interstate 77

Introduction

Interstate 77 in Virginia runs from North Carolina to West Virginia and provides another important corridor for commerce in the commonwealth’s mountainous southwest.

It was built in the late 1960s and early 1970s. It used to take almost 45 minutes to travel one 23-mile segment along a twisting mountain road. After a tunnel was built, that trip was reduced to 15 minutes over 12 miles.

I-77 has Virginia’s only mountain tunnels: Big Walker, which opened in 1972, and East River, which opened in 1974.
