An approximate 450-foot section of the Adirondack Rail Trail that runs by the Saranac Lake Union Depot will be closed through Thursday. The Adirondack Daily Enterprise reports a detour route that goes through an adjacent parking lot north of the former train station is in place during the closure. The state Department of Environmental Conservation announced the temporary closure midday Saturday. A DEC contractor will be painting and doing some lead paint remediation on the depot’s north side.
