In GA if the road has been opened and used by the public it can't be closed. Late 80's I had 50 acres on a dirt road and the only house or land on that road. The road was L shaped and my house was in the corner and a two path road went around the outer edge of my yard to a highway on each end. I couldn't close the road. If the property is land locked with no access an easement will legally be granted. I bought 75 acres land locked from the US Marshalls service that had been seized in drug recovery. Before I put in my bid I made sure I could legally have access. Check your state laws but I don't think the road can be closed.
