N.Y. High. Law § 248
The board of supervisors of any county may, and upon the presentation of a petition signed by fifty per centum of the owners of real property and representing a majority of the assessed valuation of the town or city in which a toll bridge is wholly or partly situated must, except where such bridge extends between the state of New York and a foreign country, pass a resolution that public interest demands the abolition of such toll bridge situate wholly or partly within said county. In case of a toll bridge situated in two counties such resolution shall be a concurrent resolution passed by the boards of supervisors of the counties wherein said bridge is situated. Within ten days after the passage of such resolution the clerk or clerks of the board or boards of supervisors shall transmit certified copies thereof to the department of transportation. Before transmitting such certified copy or copies to the department of transportation, the board or boards of supervisors shall investigate as to the value of such toll bridge and shall prepare an estimate of the probable cost of acquiring the same, and the clerk or clerks shall transmit such estimate, together with any data in relation to the value of such toll bridge which the board or boards of supervisors may secure, to the department of transportation with the certified copy or copies of such resolution.
