Northern Terminus: Mount Mitchell State Park
Southern Terminus: Blue Ridge Parkway
Total Miles: 4
It is the only state highway with no direction designation. And the only highway in North Carolina that has no intersections with any road other than its endpoints.
For the sake of simplicity, I gave this route a north-south designation. I honestly don't believe this highway has one since it wasn't signed with one nor the fact it really would need one (your either on it or not).
