Private property with a private road with no easements or other title claims are pretty much in the complete control of the land owner. Most public roads, I believe, are actually created by an easement, which is for all purposes makes them the property of the government. You may own "title" to the middle of the road, but you really have no equitable ownership rights, except maybe the privilege of mowing it from time to time.
There are instances where private property is subject to an easement, whereby the public has the right to enter in order to access public land or maybe a public road. Also, if you own a land locked piece of land, surrounded by other private property with no roads, you have a legal right to access that property, in spite of the fact that the access is owned by someone else. You may have to go to court and pay for the access, but the right is there. The street in front of my house was built, created and paved by the builder because we were rural. That's all well and good, but if the homeowners actually own it, they are responsible for maintenance, and we will have to take our garbage cans about a hundred yards or more to the main road. The city has resurfaced the street at least once, and I never objected. As far as I'm concerned, I have ceded it to the city!
