This bill mandates the New Hampshire Department of Transportation to install and maintain mile markers along Route 112, also known as the Kancamagus Highway, specifically from the town of Lincoln to the town of Conway. Additionally, it allows the department to install mile markers on an extended section of Route 112, from the town of Bath to the town of Woodstock. The mile markers are to be placed at regular intervals of no more than one mile, ensuring they are visible and legible for both motorists and emergency personnel, although markers may be omitted in densely developed areas.

Furthermore, the bill stipulates that the Department of Transportation is responsible for maintaining these mile markers in accordance with the Federal Highway Administration’s Manual on Uniform Traffic Control Devices. Before installation, the department is required to consult with public officials from Lincoln and Albany to discuss the design, proposed locations, and potential traffic impacts of the mile markers. The act is set to take effect 18 months after its passage, with an effective date of January 15, 2027.
