The selectmen shall notify the Commissioner of Forests, Parks and Recreation when they have filed a petition to discontinue a highway under this subchapter. The selectmen may designate the proposed discontinued highway as a trail, in which case the right-of-way shall be continued at the same width. The Commissioner of Forests, Parks and Recreation with the approval of selectmen, may also make this designation. If the discontinued highway is not designated as a trail, the right-of-way shall belong to the owners of the adjoining lands. If it is located between the lands of two different owners, it shall be returned to the lots to which it originally belonged, if they can be determined; if not, it shall be equally divided between the owners of the lands on each side.
