The
Saw Mill River Parkway (also known as the
Saw Mill Parkway or the
Saw Mill) is a north–south
parkway that extends for through
Westchester County, New York, in the United States. It begins at the border between Westchester County and
the Bronx, as the continuation of the
Henry Hudson Parkway leaving
New York City, and heads generally northeastward to an interchange with Interstate 684 (I-684) and New York State Route 35 (NY 35). At its north end, the parkway serves as a
collector/distributor road for both highways as it passes east of the
hamlet of
Katonah. The parkway is named for the
Saw Mill River, which the highway parallels for most of its length.
