The Saw Mill River Parkway is a north–south parkway that extends for 28.93 miles (46.56 km) through Westchester County, New York, in the United States. It begins at the border between Westchester County and the Bronx, where it continues into New York City as the Henry Hudson Parkway, 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.

The Saw Mill serves as an important connection from the Taconic State and Sprain Brook parkways to the Tappan Zee Bridge and New York State Thruway. It is not a limited-access highway as several of its exits are signalized at-grade intersections. However, most of the road has a high speed limit in spite of this fact.[citation needed] The Saw Mill River Parkway is inventoried by the New York State Department of Transportation (NYSDOT) as New York State Route 987D, an unsigned reference route designation.


Route description

The Saw Mill Parkway started construction in 1926. By 1930, it had reached Route 119 in Elmsford. Construction had only reached Chappaqua by 1940 when World War II halted any further progress. The Saw Mill Parkway was constructed along the Saw Mill River, as a sort of flood control project that never really worked right.[2] The full length of the parkway was opened in 1955.

The Parkway once fed into the accident-prone Hawthorne Circle, a former roundabout at the intersection of the Taconic Parkway extension from the Bronx River Parkway, Taconic State, and Saw Mill River parkways. In 1972 the circle was rebuilt as a three-level interchange.

NYSDOT has maintained the Saw Mill River Parkway since 1980. Under NYSDOT, the 25¢ toll between exits 3 and 4, which was originally implemented by Westchester County in 1936, was removed on October 31, 1994.[3]
