If, after the examination and hearing, the commissioners determine that the highway or bridge is out of repair or unsafe for travel, and that the public good demands that the highway or bridge be repaired, they shall determine what work or repairs are necessary. They shall make a written report of their findings, containing a full description of the repairs or work required and a statement of the amount estimated to accomplish it, and shall conclude with an order to the town to make the repairs or perform the work within such time as they judge reasonable. No town shall be required to spend more than twenty cents per hundred dollars on its grand list in any one year including costs of the proceedings. If they determine that the highway or bridge is not out of repair or unsafe for travel they shall make a written report of this finding. (Added 1985, No. 269 (Adj. Sess.), § 1.)
