§ 207. Discontinuance of highway. Whenever the town superintendent of any town shall determine that any portion of any highway or street, not within the limits of an incorporated village, which is the terminus of such street or highway, is unnecessary for highway purposes, and said town superintendent may, by an order to be duly entered in the town clerk's office, direct such highway to be discontinued and abandoned for public purposes. Provided, however, that no portion of such highway to be discontinued shall be greater than one thousand feet of the terminus thereof and that the owners of the land on both sides of such highway or street, for the distance it is proposed to discontinue the same, shall, by written petition to such town superintendent have requested the discontinuance thereof.
