The state Department of Transportation will begin removing rail crossings on highways in Lake Placid and Saranac Lake this week and drivers can expect minor delays. The Adirondack Daily Enterprise reports the work is the latest in the state’s project of removing train tracks from Tupper Lake to Lake Placid and converting that stretch into a trail for snowmobiles, hikers, bikers and skiers. Portable message boards will be deployed along the routes to warn motorists of ongoing work. Work zones will be controlled by flaggers.
