Question about legal access to land parcel

[Kyle Conrad]

So long story short - I've agreed to terms from the seller to purchase a parcel of land in a rural area. The land itself is fine - wooded but flat, zoned for residential building, etc. However, the only way to access the parcel is through a private access road - a road the several other residents are also using. I've called the county and they don't know who's name the access road is in, but I'm wondering what kind of issues this could pose in the future.

Theoretically, since the road is private, could I effectively be unable to access my land if the owner of the private road decides to restrict access? I'm in North Carolina, FWIW.
