Route description

The highway begins in Yonkers where it splits from I-87 at Exit 5, then traverses almost the entirety of Westchester County. NY 100 passes through Yonkers, Greenburgh, and southern White Plains. Residents in southern Westchester call the highway "Central Avenue," though it is only officially given this name within the City of White Plains. In the City of Yonkers and the Town of Greenburgh, it is officially known as Central Park Avenue. It is a major north-south thoroughfare in southern Westchester and is a large shopping area, often drawing shoppers from the Bronx and New York City.
It overlaps with NY 119 for a short distance before turning north again through Mount Pleasant, where it meets NY 9A and overlaps for several miles as a limited-access highway. NY 100 branches off on its own again in Briarcliff Manor, roughly following New York Central's old Putnam Division railroad. Many of the railroad's old stations can be found along the highway.
It passes through New Castle just after crossing the Taconic and then into Yorktown where it diverges from the Putnam Division just before crossing the Croton Reservoir After crossing the reservoir it enters Somers and passing some of the last remaining rural areas in the county. Including Muscoot Farm, a county owned early-1900's interpretive farm. In its northern extremes, it roughly parallels the Croton Reservoir before meeting up with US 202, where it ends.
