Mass. Gen. Laws ch. 82 § 32A
The board or officers of a city or town having charge of a public way may, after holding a public hearing, notice of which shall be sent by registered mail, return receipt requested, to all property owners abutting an affected road and notice of which shall be published in a newspaper of general circulation in the city or town once in each of two successive weeks, the first publication to be not less than fourteen days before the day of the hearing and by posting in a conspicuous place in the office of the city or town clerk for a period of not less than fourteen days before the day of the hearing, upon finding that a city or town way or public way has become abandoned and unused for ordinary travel and that the common convenience and necessity no longer requires said town way or public way to be maintained in a condition reasonably safe and convenient for travel, shall declare that the city or town shall no longer be bound to keep such way or public way in repair and upon filing of such declaration with the city or town clerk such declaration shall take effect, provided that sufficient notice to warn the public that the way is no longer maintained is posted at both ends of such way or public way, or portions thereof. Upon petition in writing of the board or officers of a city or town in which a county highway is located, the county commissioners, whenever common convenience and necessity no longer require such way to be maintained in a condition reasonably safe and convenient for public travel, after giving notice in the manner prescribed in section 3, and after viewing the premises and hearing the interested parties in the manner prescribed in section 4, may adjudicate that the town shall no longer be bound to keep the way in repair, and thereupon the adjudication shall take effect; provided, that sufficient notice to warn the public that the way is no longer maintained is posted at both ends of the way, or portions thereof.
