(exit 20) in the Quaker Ridge section of New Rochelle. Access to the Parkway northbound is via Hutchinson Avenue while southbound access is provided via Stratton Road and Pinebrook Boulevard. County maintenance ends just south of the junction while NY 125 continues past the parkway along the New Rochelle–Scarsdale line. It serves residential parts of both communities prior to fully entering Scarsdale and accessing the Heathcote section of the village. Here, the route connects to the west end of the Heathcote Bypass, a two-lane highway running below grade along the northern edge of the neighborhood. The bypass is designated County Route 143 and signed as NY 125 Bypass. NY 125 continues directly into the center of Heathcote, where it turns northeast onto Palmer Avenue at an intersection known locally as the Five Corners. The route continues northeastward for several blocks before gradually turning back to the north as it heads into nearby Secor Gardens. The Palmer Avenue name ends at a junction with Secor Road, at which point NY 125 becomes known by the latter name. One block to the north, the highway connects to the east end of the Heathcote Bypass. From here, NY 125 takes a northeasterly track out of Secor Gardens and Scarsdale, passing the Fenway Golf Club on its way into the city of White Plains. Across the city line, maintenance of the route shifts to the county once again as CR 26. Now known as Old Mamaroneck Road, NY 125 serves several of the city's residential neighborhoods as it approaches downtown White Plains. The highway crosses into Gedney Park, becoming a two-lane residential street as it approaches Mamaroneck Avenue. At this junction, NY 125 shifts from a county-maintained road to a city street as it turns northwest through downtown White Plains. The route continues for another three blocks to its north end at junction with
