If I understand correctly, what you want to do is exactly the way my (and my in-law's) property is done in TN. We have a "common-use access easement" road that divides (runs between) our property and the adjacent landowners. When I sold a portion of my property to my in-laws, we made sure that just a little bit of their property line was also in the existing "common-use access easement". It is written into all three deeds.
How this happened is that originally, it was all one large parcel with the road running down the middle of it. When the earlier owner's heirs inherited and sub-divided it, they used the road as part of the boundary, and each new portion had the "common-use access easement" written into the deed.
It has worked terrific, except that the adjacent property owners (original heirs) are non-resident and don't participate at all in road maintenance as they are really supposed to. On the other hand, when I asked for their permission to run a water line down the middle of the road, and to install a gate and gate operator across the road, they had no objections. I suppose it might go badly for me if they should ever suddenly become cranky and try to dig up part of the waterline where it doesn't stay exactly in the middle of the road, or tear down the gate! I've given their whole family, and anyone else they have specified, access codes for the gate opener.
