Past the district, the route changes names to Centerway and crosses over the Chemung River, which flows east–west through the center of Corning.

Across the river, the route traverses more commercial neighborhoods to reach Pulteney Street, designated as NY 415 west of this point.

The composition of the exit's ramps is unorthodox in that the westbound on-ramp for I-86 and NY 17 is about 0.25 miles (0.40 km) north of the remainder of the interchange.

Another is the alignment of the STE itself, which runs in close proximity to NY 414 for a short distance as it bypasses northern Corning while avoiding the hilly terrain north of the city.

[4] Over the next 7 miles (11 km), NY 414 and the rail line head due northeast through a valley surrounding Post Creek, traversing rural, isolated areas as both cross into Chemung County.

Past the county line, the valley turns to the north, reflecting a similar curve in the creek's routing.

The creek eventually heads east toward Montour Falls; however, NY 414 and the rail line continue northeast to the outskirts of Watkins Glen, a village located inside of a wide valley holding Seneca Lake.

At the western edge of the gully, the Corning Secondary breaks from NY 414 to follow the ridge north through Watkins Glen State Park.

The route, meanwhile, descends the side of the valley to enter Watkins Glen, where it merges with NY 14 at the foot of the hill.

The routes pass by several blocks of homes as they follow the western base of the ravine and meet the east end of NY 329, which ascends the side of the valley to serve Watkins Glen State Park.

[4] The route initially heads east from Watkins Glen to skirt the southern edge of the lake, but turns north upon exiting the village and passing the southeastern tip of the waterbody.

It continues on a northeast alignment across more level terrain to the village of Lodi, where it intersects and forms an overlap with NY 96A.

The two routes head due north from Lodi, crossing relatively flat farmland to reach the neighboring village of Ovid.

Just past the town line, the highway connects to Finger Lakes Regional Airport[4] and passes by a large field that hosts the annual Empire Farm Days exhibition every August.

Past the crossing, the businesses give way to mostly undeveloped areas that persist into the neighboring town of Tyre, where it intersects NY 318 in the small hamlet of Magee as Ridge Road.

North of the Thruway, NY 414 maintains a constant north-northwest alignment across rolling farmland into Wayne County.

[4] Across the county line, NY 414 veers slightly to the west and east as it heads north across rural terrain to the village of Clyde, located on the Erie Canal and the CSX Transportation-owned Rochester Subdivision.

[4] North of Clyde, NY 414 intersects a number of roads of local importance as it heads north-northwest across gentle terrain in the mostly open towns of Galen and Rose as Main Street.

[11][12] By 1929, the route was extended northward over a new highway that followed the eastern edge of Seneca Lake between Ovid and Geneva.

[35][36] The portion of NY 414 south of Pulteney Street was realigned slightly c. 1979 following the completion of the Briscoe Bridge across the Chemung River.

[37] When the Corning Bypass (part of the Southern Tier Expressway) was built in the mid-1990s,[38][39] Baker Street was split into two segments.
