Route descriptionEdit

View south along I-77 just south of the East River Mountain Tunnel in Bland County

Within Virginia, the milepost count begins from the south at the North Carolina border and ends at the West Virginia border.

For eight miles (13 km) in the Wytheville area, Interstate 77 and Interstate 81 share the same roadway and form a wrong-way concurrency. Interstate 77 north is signed with Interstate 81 south and vice versa.

The southernmost 7 miles involve a steep grade, up for northbound and down for southbound traffic. The southbound side has 2 runaway truck ramps. The lower end of the grade coincides with the North Carolina border, where the road exits the Appalachian Mountain region and levels out.

The entire length of I-77 in Virginia is also part of the proposed Interstate 74.[citation needed]

I-77 crosses the following mountains:
