The return of NC 15

There is no North Carolina State Highway 15, since that would conflict with US 15. Somebody in NCDoT has mistakenly made some NC 15 shields with the diamond shield when they meant to make US 15 shields.

About two years ago, these signs were installed at the intersection of US 15/501 and NC 54. What was funny was that sign complexes had both US 15 and NC 15 shields, one for northbound and the other for southbound. Unfortunately, I didn't get any pictures before the NCD0T realized their mistake and replaced the shields.

This week, one of the NC 15 shields reappeared. It is not quite as ironic as the previous shields, except that NCDot made the same error again.

Notes
This was primarily a county tagging trip. The only odd thing I saw were the signs at US 360 and VA 360. The regular shields had banners for STATE and US above them, to make sure people would not be confused.
I had counted Lunenburg as having been visited by driving on I 85, but I 85 just misses the county. It appears that US 360 enters the county in the area around Meherrin, but here are no county signs on the highway. I saw some along side roads, so I ducked off on SR630 and found a sign and turned around.
Farmville was a good locus for visiting counties, there are four that I visited within ten miles of town.
