 Across the county line in Lake Luzerne , NY 9N begins to deviate from the Hudson River , gradually curving to the northeast as it passes through the hamlets of Lake Luzerne , Fourth Lake , and Lake <unk> , all of which are named for small lakes bearing those names near the center of the communities . Just northeast of Lake <unk> , NY 9N enters the town of Lake George , where it connects to I @-@ 87 ( the Adirondack Northway ) at exit 21 and meets US 9 . Here , it joins its parent route northward toward the village of Lake George . The conjoined routes intersect the northern end of NY 9L just south of the village line before becoming Canada Street and entering the village limits upon crossing over West Brook . US 9 and NY 9N serve as the primary north – south thoroughfare through the village before splitting at the north end of the village . While US 9 continues to the north , NY 9N heads northeast along the western edge of Lake George .
