turns eastward to follow the northern edge of Portageville. The route occupies the northernmost road in Portageville between NY 19A and Main Street, one that is initially devoid of development due to its proximity to the Genesee River gorge. As NY 436 approaches Main Street, it trends slightly southward to serve a small handful of homes. At Main Street, NY 436 abruptly turns north and crosses the Genesee River gorge, reentering Letchworth State Park as it passes into Livingston County and the town of Portage. Across the river, the route gradually turns to the east as it ascends the side of the gorge and passes under the Norfolk Southern Railway-owned Southern Tier Line. NY 436 leaves both Letchworth State Park and the Genesee River shortly afterward. Nunda to Dansville East of the park, NY 436 straightens out and takes an easterly alignment across open, cultivated fields to an intersection west of the Portage hamlet of Oakland, where the road meets the western terminus of NY 70. From here, NY 436 curves to the northeast for a short distance before resuming its eastward routing through the small hamlet of Oakland and into the town of Nunda. Just east of Oakland is the village of Nunda, which NY 436 enters as Portage Road. It proceeds eastward into the village center, where it connects to NY 408, the village's main north–south highway. While NY 408 heads through Nunda's linear commercial district, NY 436 continues east through a more residential portion of the village as Mill Street. Outside of Nunda, NY 436 switches names once again to Nunda–Dansville Road, named for the two communities that the last segment of the road links. east of NY 408, NY 436 dips to the south for another mile, ascending in elevation as it climbs the side of a ridge overlooking the village of Nunda. It curves back to the east at the top of the ridge and generally maintains an east–west alignment for the rest of its length. The route winds its way across a mixture of farmlands and undeveloped areas in the towns of Ossian and North Dansville to the village of Dansville, where NY 436 passes under Interstate 390 on Ossian Street before ending two long blocks later at Dock Street, designated as NY 36. At this point, NY 36 leaves Dock Street and continues eastward on Ossian Street toward the village center. History The
