 While NY 426 leaves NY 430 to follow the eastern edge of the lake southward toward French Creek, NY 430 continues to the northeast, passing through the hamlet of Mina and over the Southern Tier Expressway (I-86 and NY 17) on its way to the town of Sherman and the village of the same name. Within the village of Sherman, NY 430 becomes Main Street and intersects NY 76 west of the village center. The two routes overlap for a single block before separating at the heart of the village, with NY 76 continuing southward to an interchange with the Southern Tier Expressway just outside the village and, farther south, to its southern terminus at NY 474 in Clymer. NY 430, however, exits Sherman to the east before turning northward to parallel an old railroad bed northward into the town of Chautauqua.
