19 V.S.A. § 316

When a town or the Agency decide that the destruction or removal of a covered bridge is necessary, whether by discontinuance of the highway or to replace the bridge with another structure or for any other reason, notice of the intent to destroy or remove the bridge shall be posted by the officials in three public places in the town where the bridge is located and published on two consecutive days in a newspaper of general circulation in the town. Copies of the notice shall be sent by certified mail to the Governor and the Director of the Division for Historic Preservation not less than 90 days before destruction or removal is to be started, and the date of the proposed destruction or removal shall be stated in the notice. The requirement for a 90-day warning shall not apply in the event of a serious emergency.
