Not adopted
In Norwich, street signs labeled “Not Adopted” indicate that the road in question is not maintained by the local authority, such as the Norwich City Council or Norfolk County Council.
These roads, often referred to as “unadopted roads,” are privately owned and maintained, meaning the responsibility for their upkeep, including repairs, lighting, drainage, and snow clearance, falls on the residents or property owners who use them.
I’d love to be in one of those meetings of residents.
