Tier Expressway (Interstate 86/NY 17) southeast of the hamlet of Kennedy. US 62 continues on to Kennedy, where it crosses the creek once more and intersects NY 394. US 62 curves eastward, joining NY 394 northeastward out of Kennedy to a junction known as Schermerhorn Corners. Here, NY 394 continues eastward along the banks of the creek while US 62 heads northward through a small valley surrounding Indian Brook and into the town of Ellington. South of the hamlet of Ellington, the small creek valley gives way to a larger cut of land surrounding Clear Creek. Indian Brook ends near this point; however, US 62 continues northward to serve the community. In Ellington, US 62 turns eastward for before veering back to the north at the Chautauqua–Cattaraugus County line. The route straddles the county line and runs along the base of a larger valley surrounding Conewango Creek to the aptly named community of Conewango Valley, where it intersects NY 83, which heads northwestward into Chautauqua County while US 62 curves eastward to traverse the width of the valley. In the hamlet of Conewango, US 62 meets NY 241 and turns north to follow the eastern edge of the valley through the town of Conewango. Upon entering the town of Leon, US 62 veers slightly northeastward to run along the base of a small valley surrounding Mud Creek. The two entities separate at the hamlet of Leon and US 62 returns northward, descending the eastern side of the Conewango Creek valley and becoming the eastern valley road once again. Just before crossing into the town of Dayton, US 62 leaves the edge of the valley and heads northward through the gully. Here, it crosses over Conewango Creek once more and intersects NY 322. At the northern extent of the ravine, US 62 turns northeastward toward the community of Dayton, the site of its junction with NY 353. Past Dayton, the valley becomes much less defined as the route follows a small stream through the town of Persia and into the village of Gowanda. US 62 becomes Jamestown Street and serves as the primary north–south street through the community. It intersects NY 39 in the village center, and the two routes embark on an overlap along Main Street. Just past the junction, the two routes cross Cattaraugus Creek and enter Erie County.
