 The two routes embark on an overlap northward into Ontario County.Shortly into Ontario County, NY 247 separates from NY 245, taking a due north alignment through the town of Gorham.NY 245 continues eastward through predominantly hilly terrain, passing through the hamlets of Gorham (where it crosses Flint Creek) and Stanley (located in the town of Seneca, centered around a former junction between the Pennsylvania and Lehigh Valley railroads adjacent to NY 245, now part of Ontario Pathways Rail Trail) before meeting NY 14A at a rural junction in the town of Seneca.
