Notes

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

I-81 runs together with Interstate 77 in Wytheville, Virginia for about 10 miles (16km), but the two go in opposite directions. 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.
