West of
Mayville, NY 430 is a largely rural route connecting
Erie, Pennsylvania, (via
Pennsylvania Route 430 or PA 430) to Mayville via
Sherman; however, east of Mayville, the route is a primary arterial serving the northern and eastern shores of
Chautauqua Lake. NY 430 briefly
overlaps with NY 426 through the community and past the northern tip of the waterbody that gives the hamlet its name. The two routes split at the eastern edge of the community. 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. Due to the narrow width of the lake at Bemus Point, a
ferry once ran from the end of Lakeside Drive to the
North Harmony hamlet of Stow; however, it has since been replaced with the
Chautauqua Lake Bridge on the Southern Tier Expressway farther south. NY 430, however, turns southeast at Main Street and connects to the aforementioned expressway at the eastern end of the Chautauqua Lake Bridge by way of an interchange near the southern edge of Bemus Point. NY 430 continues eastward into the city of Jamestown, where it becomes Fluvanna Avenue. Within the city, NY 430 turns southward from Fluvanna Avenue onto Washington Street and heads toward downtown. The eastern terminus of NY 430 comes at an intersection with
NY 394 westbound (West 5th Street). The state highway is signed to the next block with West 4th Street where NY 394 heads east and
NY 60 turns from Washington Street onto West 4th Street. ==History==
