Never mind on the NC 36 following existing NC 42

There's a map showing NC36 using Ranch Road (and so, if it were NC42, it would have remained concurrent with former US70 and had just one intersection with current US70 as before, but just flipped where that concurrency was as former US70 moved - very odd!).
Right, I thought it might be temporary as construction was needed on Ranch Rd to put NC 36 on it, but I guess that is done or close to done.
