New York State Route 129 (NY 129) is a 7.75-mile (12.47 km) long state highway in the western part of Westchester County, New York. The route begins at New York State Route 9A (South Riverside Avenue) in the village of Croton on Hudson at the Hudson River. NY 129 then travels through the towns of Cortlandt and Yorktown, running along the northern edge of the New Croton Reservoir. It passes under (southbound) and over (northbound) the Taconic State Parkway in Yorktown with no direct interchange. NY 129 ends in Yorktown at an intersection with NY 118.
NY 129 was designated in 1908 as a section of Route 2, a legislative route designated by the New York State Legislature. However, in 1921, the route was realigned off the route that would become NY 129 in favor of NY 9A. Nine years later, the state designated the route as NY 129 during the state highway renumbering. The route originally followed a route used by NY 131 once the routes were swapped in the 1940s, with NY 131 being decommissioned soon after. NY 129 was extended to end at a traffic circle with NY 100 in the hamlet of Pines Bridge. This lasted up to at least 1969, when the designation was truncated back to NY 118, which was extended to the traffic circle instead. The traffic circle in Pines Bridge was removed by 1991. Originally, NY 129 had an interchange with the Taconic, but the ramps were removed in 1969 and a new interchange was built on nearby Underhill Road.
