Stonytown Road runs east-west through the incorporated villages of Flower Hill, Plandome, and Plandome Manor. The road serves as a main west-east route through portions of all three villages, and is the main access road for the
Plandome station on the
Long Island Rail Road's
Port Washington Branch, as well as the
Plandome Post Office (located at the station). The road is classified as a
major collector roadway by the
New York State Department of Transportation and is eligible for federal aid. When this segment was a county-maintained road, it was designated as Nassau County Route 143, before being re-numbered as CR E43 and then ultimately being transferred back to the Village in the 2000s. The road continues through Plandome Manor until entering Flower Hill just west of Manhasset Woods Road. Stonytown Road then continues through Flower Hill to its eastern terminus, at
Port Washington Boulevard (NY 101).
Bicycle and pedestrian path The portion of Stonytown Road between the Plandome Long Island Rail Road station in Plandome Manor and its eastern terminus in Flower Hill features a dedicated bicycle and walking path. This dedicated bicycle and pedestrian pathway was constructed in the 2010s to improve safety for bicyclists and pedestrians along the road. == Major intersections ==
