Notes

This road is a "line on a map" Interstate. Mainly it exists more so people can have a path through the Appalachians than to relieve congestion on that busy Roanoke-Harrisburg route.

Motorists traveling northbound on I-81 are also traveling southbound on I-77, though they are actually going east. Likewise, motorists traveling southbound on I-81 are also traveling northbound on I-77, though they are actually going west.
