I. All class V highways shall be constructed, reconstructed, and maintained by the city or town in which they are located; provided, however, that town road aid may be used for such purposes, and town bridge aid may be used for the construction or reconstruction of any bridge thereon, as hereinafter provided.
II. If a city or town accepts from the state a class V highway established to provide a property owner or property owners with highway access to such property because of a taking under N.H. Rev. Stat. § 230:14, then notwithstanding N.H. Rev. Stat. § 229:5, VII, such a highway shall not lapse to class VI status due to failure of the city or town to maintain and repair it for 5 successive years, and the municipality’s duty of maintenance shall not terminate, except with the written consent of the property owner or property owners.
