The route heads east, following the four-lane White Plains Road through a mostly residential area of the village.

NY 119 continues through this area to the western edge of the village of Elmsford, where it meets I-87 and I-287 at an interchange just east of where the two Interstate Highways split.

NY 119 continues into Elmsford, becoming Main Street and narrowing to four lanes as it connects to the Saw Mill River Parkway at an interchange just west of the village center.

Outside of Elmsford, NY 119 becomes Tarrytown Road as it maintains a southeasterly alignment through the rest of the commercialized town of Greenburgh.

[4] The portion of the route west of the one-way couplet in White Plains is maintained by the New York State Department of Transportation (NYSDOT).

[5] NY 119 was established as part of the 1930 renumbering of state highways in New York and originally ran 13 miles (21 km) from Tarrytown through White Plains to Port Chester.

[10][11] It was cut back to the junction of I-287 and NY 127 by the following year[12] and to its current eastern terminus in White Plains in the 1970s.
