The road begins to run along the west shore of Schroon Lake, in the process crossing into Essex County. Shortly after the county line, an access road leads to I-87 again. It is from here, past the hamlet of Schroon Lake at the water's northern tip, that US 9 intersects NY 74, like NY 254 and NY 149 fresh off its western terminus at the Northway. Signs at this junction use Ticonderoga, to the east, as a control city, an indication of how sparsely populated the park is.
