The Saw Mill River Parkway (also known as the Saw Mill Parkway or the Saw Mill) 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, 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.
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, as well as connecting New York City, particularly Manhattan, with Westchester County and Upstate New York. It is not a limited-access highway as several of its exits are signalized at-grade intersections. The Saw Mill River Parkway is inventoried by the New York State Department of Transportation (NYSDOT) as New York State Route 987D (NY 987D), an unsigned reference route designation.
The Bronx to Elmsford
The Saw Mill River Parkway begins at the Bronx–Westchester line in Van Cortlandt Park as a continuation of the Henry Hudson Parkway. The Saw Mill River winds northward and parallels a former railroad grade into Yonkers. Now in the Southeast Yonkers section, southbound there is a ramp to McLean Avenue. Passing Tibbetts Lake, the Saw Mill River winds northward alongside the railroad grade as a four-lane roadway as it enters exit 4, which serves as the western terminus of the Cross County Parkway. Immediately after the Cross County, exit 5 forks off on a 180-degree turn for Yonkers Avenue and nearby Dunwoodie Golf Course. The parkway curves northward, entering exit 5A, which services Palmer Road in Northwest Yonkers.
Winding northward through Yonkers, the Saw Mill River Parkway enters exit 6, a southbound exit/entrance with Lockwood Avenue in Yonkers, follow by exit 7, a northbound exit and entrance with NY 9A and Tuckahoe Road via Rossiter Avenue. After exit 7, the parkway begins paralleling Saw Mill River and NY 9A, now known as Saw Mill River Road, near the Runyon Heights neighborhood. After a southbound entrance at Nepperhan Avenue that is officially exit 8, there is an overpass at Odell Avenue with no exit or entrance. Upon entering exit 9, the parkway enters a series of signaled at-grade interchanges. The first is exit 9, which serves Executive Boulevard in Yonkers. This marks the end of the southernmost limited access section of the parkway. This is followed by Hearst Street at exit 10 and Tompkins Avenue at exit 11. Just north of exit 11, the Saw Mill enters the town of Hastings-on-Hudson. In Hastings-on-Hudson, the Saw Mill enters exit 12, an at-grade interchange with the terminus of the Farragut Parkway.
The next exit, designated exit 13, is an interchange with Farragut Avenue on the southbound side and NY-9A on the northbound side. The four-lane parkway winds north through Hastings-on-Hudson, passing through several suburban sections of town. Keeping in close contact with NY 9A and the Saw Mill River. Exits 14 and 15 are non-signalized at grade intersections only on the southbound side at Clarence Avenue and Cliff Street respectively. The Saw Mill then crosses into Dobbs Ferry. Upon entering Dobbs Ferry, the parkway enters a signalized at grade intersection with Lawrence Street (exit 16) that provides access to a nearby shopping center as well as NY-9A. Continuing through Dobbs Ferry, the parkway enters exit 17, the first full interchange since Tuckahoe Road, connecting to Ashford Avenue. 
Continuing northbound through Dobbs Ferry, the southbound parkway enters an at-grade intersection with Cyrus Field Road. On the northbound side, there is an information & welcome center for Great Hunger Memorial Park, though there is no access to/from the southbound side. Through this section of the highway, the Saw Mill River Parkway parallels the Thruway and the river before turning northeast and crossing into Elmsford and exit 20. Exit 20 serves the I-87 northbound and I-287 via a modified flyover ramp, connecting to the Tappan Zee Bridge. There are also ramps from I-87 northbound to the northbound Saw Mill as well as from I-87 southbound to the southbound Saw Mill, however there is no southbound exit here. After exit 20, the Saw Mill River Parkway proceeds northeast on a parallel of NY 9A. Continuing alongside the Saw Mill river, the parkway enters exit 21E and exit 21W, which services NY 119 (Main Street) via separate ramps. After a dart to the northwest, the Saw Mill River Parkway crosses under the Cross Westchester Expressway (I-287). While there is no exit northbound or entrance southbound, exit 22 is a southbound exit and northbound entrance to the westbound Cross Westchester.to I-287 westbound and I-87, connecting to the Tappan Zee Bridge, as well as NY-119 westbound. There is also a northbound entrance from I-287 eastbound here.
Eastview to Katonah
After exit 22, the Saw Mill River Parkway continues northwest away from the Saw Mill River and up a big hill. After turning northbound and going back down the hill, the parkway crosses into Eastview and reaches exit 23, which serves Saw Mill Road and Neperan Road. Exit 23 is the only interchange in Eastview as the parkway proceeds into the town of Hawthorne. In Hawthrone, the parkway enters exit 25, and northbound exit/entrance with NY 9A (Saw Mill River Road), which also connets to NY-100. Crossing over the Saw Mill River once again, the parkway winds northeast into exit 26 near an overpass of NY 9A and NY 100 (Saw Mill River Road). Exit 26, just to the east of NY 9A/NY 100, services the Taconic State Parkway, and Sprain Brook Parkway in the center of Graham Hills County Park via several flyover ramps, though is same directional access only. Just to the southeast of the interchange is the Hawthorne Metro-North Railroad station.
The Saw Mill River Parkway crosses northeast through Graham Hills County Park, paralleling the Harlem Line and NY 141, briefly entering Thornwood. The parkway passes west of the former Thornwood station before turning northwest and away from NY 141. Crossing into the Pleasantville, the parkway turns into exit 27 comes at-grade, a junction with Marble Avenue, which connects to NY 141. Going northward into the village of Pleasantville, exit 28 forks off northbound only to Bedford Road, which connects to downtown Pleasantville and NY-117. Proceeding southbound, exit 29 accesses NY 117 (Pleasantville Road). The parkway turns northeast and enters exit 30 for Grant Street near the Pleasantville Metro-North station.
The Saw Mill River Parkway and the Harlem Line parallel once again in the northern reaches of Pleasantville, paralleling the Saw Mill River into the town of Chappaqua. Passing by the Chappaqua Metro-North station, exit 32 on the southbound side goes to Mill River Road, providing a short connection to NY-120. Crossing under NY 120, the northbound exit 32 connects to Hunts Place, which connects to NY 120. Running along a hillside into Mount Kisco, the parkway becomes a divided highway for a short distance. No interchange is present along this stretch and the lanes come back together just south of exit 33, an at-grade intersection with Readers Digest Road. This is the northernmost at grade interchange on the parkway. At this interchange, the parkway has access to the former Global Headquarters of Reader's Digest.
The parkway continues northeast through Mount Kisco, passing northwest of the Mount Kisco Country Club. Just southwest of the Mount Kisco Metro-North station, the parkway and railroad fork in different directions, with the parkway turning north into exit 34, an interchange with NY 133 (West Main Street). In the northern reaches of Mount Kisco, exit 36 services Croton Avenue from the southbound lanes. Just to the north, the Saw Mill River Parkway enters exit 37, a junction with Kisco Avenue and nearby Pines Bridge Road (unsigned County Route 1323). Now in the town of Bedford, the parkway enters exit 38, a northbound exit/entrance with Green Lane. 
Crossing south of Bedford Hills Memorial Park, the Saw Mill River Parkway enters Bedford Hills. In Bedford Hills, the parkway enters exit 39, which connects to NY 117 (Bedford Road). Also present at this interchange is the Bedford Hills Metro-North station. The parkway divides once again through Bedford Hills, paralleling NY 117 through the community. The parkway then enters Katonah just before exit 42, an interchange for NY 117 and Railroad Avenue. The exit numbering here is strange because there is no exit 40 or 41. NY 117 crosses over the parkway at Harris Road, paralleling the parkway before ending at the Parkway at exit 43, a northbound entrance and southbound exit. The Saw Mill enters an interchange shortly after exit 43 with Interstate 684 and NY-35, where the parkway terminates just east of Katonah.  This interchange is same directional access only, with the northbound Saw Mill only having direct access to I-684 northbound and NY-35, and northbound I-684 only having direct access to NY-35 and not the Saw Mill.
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 along with a sewer which was to both drain sewage from Yonkers and act as flood control for points north. 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 State, Sprain Brook, and Saw Mill Parkways, as well as NY-9A and NY-100. In 1972 the circle was rebuilt as a three-level interchange with same directional flyover ramps between the three parkways.
NYSDOT has maintained the Saw Mill River Parkway since 1980, after abolition of the East Hudson Parkway Authority. 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, with the last tour just before midnight. The tolls were abolished on the Saw Mill River and Hutchinson River parkways in November 1994.
In 2018, NYSDOT rebuilt the northbound exit/entrance at exit 17 in Dobbs Ferry.
The entire route is in Westchester County.
