Just north of Rutherford Road, NY 310 turns away from the Grasse River, proceeding northeast towards Trout Brook. At the junction with Planty Road, NY 310 and Trout Brook begin running alongside each other, entering a large junction with CR 38 (Madrid–Norfolk Road) and CR 44 (Norfolk–Chamberlain Corners Road). NY 310 continues northeast from this junction without the moniker, crossing from Madrid into the town of Norfolk. After a couple of miles, the route crosses a junction with Stark Road and enters the hamlet of Raymondville. In Raymondville, NY 310 becomes a two-lane residential road as it approaches the Raquette River. Running northeast, NY 310 enters a junction with CR 39 and NY 56, a large junction marking the northern terminus of NY 310.
