On the opposite side of the rail underpass, NY 415 changes names to East High Street. This moniker follows the route into the town of Erwin and its village of Painted Post, where the route gains a pair of wide shoulders and begins to traverse areas slightly more residential in nature. In the center of the village, NY 415 serves a cluster of businesses and intersects North Hamilton Street, designated as NY 417 west of this point. To the northeast, North Hamilton Street connects to CR 41. Past NY 417, NY 415 serves the predominantly residential neighborhoods that comprise western Painted Post. Just one block from North Hamilton Street, NY 415 changes names to Coopers–Bath Road at a junction with Steuben Street. The local street connects to the Painted Post Erwin Museum, housed in what was once the Painted Post station constructed by the Delaware, Lackawanna and Western Railroad.
