| has gloss | eng: The Saw Mill River is a 20 mile (32 km) long tributary of the Hudson River in the United States, flowing from a trickle in Chappaqua to Yonkers, New York, where it empties into the Hudson. Its starting point in Chappaqua is presumed to be a spring. In the 17th century, the Saw Mill River was known as Nepperhan Creek. In the 19th century, the lower portion was an important industrial area, with the New York and Putnam Railroad running along the river from Putnam County to central Yonkers, and thence to Tibbets Creek and the Harlem River. Early in the 21st century this "Old Putnam Railroad" became the South County and North County Trailways, a network of bicycle/pedestrian trails. The Saw Mill River Parkway parallels the river along its west bank for much of its route through Westchester Country, and Sawmill River Road along the east. |
