New York State Route 17K (NY 17K) is an east–west state highway located within Orange County, New York, in the United States.
It extends for 22.01 miles (35.42 km) from an intersection with NY 17 east of Bloomingburg to a junction with U. Route 9W (US 9W) midway across the city of Newburgh.
While it goes up and down some gentle hills to the first traffic light, the route intersects the six-way intersection with NY 302 (also the Long Path hiking trail) that serves as downtown Bullville.
The direction of the highway remains unchanged as it continues past several horse farms and Winding Hills Park on its way to the town of Montgomery.
The turnpike was opened in 1810 and dissolved in 1872 following the establishment of the nearby Middletown and Crawford Railroad one year earlier.
The base's entrance road, secured with a series of concrete barriers since the September 11, 2001 attacks, marks the end of the airport property.
The growing population of the area has added more traffic to the highway in recent years, forcing the school board to increase the stagger between the two schools' schedule, and hiring a police officer to direct traffic at the entrance.
About 1 mile (1.6 km) to the east lies Scotts Corners, NY 17K's intersection with NY 208.
The two form the only concurrency along NY 17K as they overlap for several more blocks to the US 9W junction at Robinson Avenue in a commercial section of Newburgh.
Modern NY 17K follows the easternmost part of the Newburgh and Cochecton Turnpike, a 19th-century toll road that extended from the Delaware River at Cochecton to the Hudson River at Newburgh.
