New York State Route 17K

NY 17K's western terminus is at NY 17 at an interchange with the Quickway before heading roughly eastward into the town of Crawford. 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.[4]

Shortly after crossing the flood-prone Muddy Kill, it reaches Ward's Bridge, where it crosses the Wallkill River and enters the village of Montgomery on Bridge Street, where it immediately passes the historic homes that line the street. The portion within the village is rather short, although consequential enough to include the traffic light at the northern end of NY 211 (Union Street). For the next two blocks, to Wallkill Avenue, the highway marks the northern boundary of Montgomery's other federally designated historic district, Academy Hill. Just before the village's eastern boundary, it passes between two more Registered Historic Places, the Patchett House and Montgomery Water Works.[4]

After the village, it passes the combined building of Valley Central High School and Valley Central Middle School.[4] 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.[5] About 1 mile (1.6 km) to the east lies Scotts Corners, NY 17K's intersection with NY 208. Just past the intersection, the headquarters of Walden Federal bank sit atop a hill on the north side of the road. Shortly afterward, Berea Elementary School adds its traffic to the nearby intersection.[4]

Past the elementary school, NY 17K runs parallel to the nearby I-84 but remains undeveloped, with the odd house, store or side street breaking the woods.[4] Much of the land here is owned by the county as part of its Farmers' Museum, which surrounds the Nathaniel Hill Brick House, an early settler's home still occupied by his descendants.[6] The next signalized intersection, Coldenham Road, provides a direct route to Walden for traffic coming from the east. NY 17K continues on toward its next light, situated at the junction with NY 747, a north–south route connecting NY 17K to I-84 and Stewart International Airport.[4]

NY 747 largely follows the original routing of Drury Lane, which carried CR 54 between NY 17K and NY 207. While most of the county road was upgraded on the spot, the part of NY 747 closest to NY 17K was built on a new alignment to the west to avoid possible damage to the Catskill Aqueduct, which crosses NY 17K here. This created a four-way intersection with Stone Castle Road, which was itself slightly relocated to the west as part of the plan to protect the adjacent Colden Mansion Ruins.[7] Not far to the east of this junction is the lone piece of Drury Lane not included in the new route,[4] which now ends in a cul-de-sac[7] but still carries the CR 54 designation south of NY 17K.[8]

Widening of NY 17K at Drury Lane in December 2006

After Drury Lane, NY 17K passes the last building of the Valley Central School District, East Coldenham Elementary School.[4] In November 1989, nine students died here when a wall collapsed during a freak tornado.[9] Development along the highway begins to increase at this point as NY 17K directly intersects I-84 and runs along the northern boundary of Stewart Airport. The Newburgh Auto Auction's vast parking lots are visible to the north while commercial hangars and the local Air National Guard base can be seen to the south. 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.[4]

The route continues on, passing north of the Orange County Choppers's headquarters just before it crosses over the New York State Thruway (I-87). East of the Thruway, NY 17K widens to four lanes with a middle turn lane and becomes heavily developed as it reaches the busy intersection with the Newburgh area's main commercial strip, NY 300. Actual access to the Thruway is no longer possible from NY 17K; instead, motorists must proceed north on NY 300 for approximately 0.5 miles (0.8 km), at which point access to both I-87 and I-84 is provided.[4] A short distance past the intersection with NY 300 is the former entrance ramp to the Thruway,[4] which was utilized from 1955 until late 2009. Originally, the state planned to eradicate this entrance/exit ramp altogether, but changed their minds at the last minute when it was determined the overpass over Route 300 was in exceptionally good condition. Now, the ramp is open only to E-ZPass holders exiting the Thruway.[10][11][12]

The four-lane section continues through the town of Newburgh to the Newburgh city limit, where it narrows to two lanes[4] and maintenance of the route switches from the New York State Department of Transportation (NYSDOT) to the city of Newburgh.[8] The route follows Broadway past several primarily residential blocks before meeting the eastern terminus of NY 207 at Wisner Avenue. Further on, NY 32 comes in from the south as Lake Street. 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.[4] Here, NY 17K ends while NY 32 turns north to join US 9W.[1][4]
