The Saw Mill River Parkway is a 28.9 mile, north-south parkway running diagonally through Westchester County, New York. Named for the Saw Mill River, which the highway parallels, the Saw Mill Parkway begins at the Westchester-Bronx border, where it continues into New York City as the Henry Hudson Parkway. The northern terminus is located in northeastern part of the county in the Hamlet of Katonah. The Saw Mill serves as a C/D road for NY-35 and Interstate 684. The road is assigned New York State Reference Route 987D.

The Saw Mill is an important connection from the Taconic State and Sprain Brook Parkways to the Tappan Zee Bridge and New York State Thruway. However, commuters to the bridge are often inconvienienced in the rain, as the Saw Mill River often floods onto the roadway. Recent roadway improvements have improved the situation.

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

The Parkway cannot be considered a limited-access freeway because it has occasional stoplights and at-grade interchanges; despite this, the road maintains a high speed limit for most of its length.

[edit] History

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].
