Any area shown on a recorded map or plat at the registry of deeds as a highway, but which does not have any physical improvement constructed on the face of the earth may be called a “paper street." For the purposes of this article, also included in this category are those roads which do exist on the ground in some form, but which have not been formally accepted as a public highway. Each “paper street" presents vexing problems for affected landowners, municipal officials, land surveyors, conveyancing attorneys and financial institutions.
