Work on rehabilitating the historic Union Depot on the Adirondack Rail Trail in Saranac Lake will begin soon, state Department of Environmental Conservation officials revealed on Tuesday. The Adirondack Daily Enterprise reports at a press conference on state grants held at the depot on Tuesday, roofing material was seen on site. DEC Region 5 Regional Director Joe Zalewski said the work to replace the depot’s roof will begin as soon as the forecast calls for a period without rain.
