Va. Code Ann. § 55.1-307

Whenever a public road that has never been abandoned but is no longer publicly maintained serves as access for more than one property owner and operates as the primary source of ingress and egress for that property, any one of the property owners may maintain, repair, or improve the road at his own expense without the express permission of the other property owners but only after administrative review by the local government. All other property owners shall be notified by mail of any pending maintenance, repair, or improvements prior to commencement of the work. Nothing in this section shall be construed as allowing the property owner who is doing the maintenance, repairs, or improvements to the road to interfere with the other property owners' use of the road for ingress and egress.
