New York State Route 417

All of NY 417 in Allegany and Steuben counties is maintained by the New York State Department of Transportation (NYSDOT). In Cattaraugus County, maintenance of the route is split between NYSDOT and the cities of Olean and Salamanca. All of NY 417 within Olean is city-maintained, save for one block of East State Street between NY 16 and Barry Street. To the west in Salamanca, the route is locally maintained from the junction of Clinton Street and Wildwood Avenue to the eastern city line. The Allegany Indian Reservation has jurisdiction over the portion of NY 417 that lies outside of the Salamanca city limits but within the reservation; however, this section is maintained by NYSDOT. where it intersects NY 248 north of the hamlet of Greenwood. Past NY 248, the route winds its way through Woodward Hollow Outside of Addison, NY 417 follows the Canisteo River and the Norfolk Southern Railway's Southern Tier Line into the adjacent town of Erwin, where it connects to I-99 and US 15 at an interchange northwest of the confluence of the Canisteo and Tioga Rivers. At this point, the railroad and NY 417 turn northeast to follow I-99/US 15 and the Tioga River into the hamlet of Gang Mills, a western suburb of Corning. In Gang Mills, NY 417 crosses the Southern Tier Line on an overpass and connects to I-99/US 15 twice: once in the community itself and again northeast of Gang Mills at Robert Dann Drive. The route continues past Robert Dann Drive on South Hamilton Street, crossing over the Cohocton River and reconnecting to the Southern Tier Expressway at exit 44, a complex semi-directional T interchange that also connects I-86 and NY 17 to I-99 and US 15. From here, the route proceeds into the village of Painted Post as North Hamilton Street, serving two blocks of mostly commercial properties before terminating at an intersection with NY 415. ==History==

Three sections of modern NY 417 were designated as part of Route 4, an unsigned legislative route, by the New York State Legislature in 1908. Route 4, a cross-state highway that began near Lake Erie in Chautauqua County and ended near the Hudson River in Orange County, proceeded east from Salamanca to Corning via Olean, Hinsdale, Belvidere, Wellsville, Andover, Hornell, Jasper, and Addison. Much of legislative Route 4 west of Harriman—including all of the route between Salamanca and Corning—was designated as part of NY 17 when the first set of posted routes in New York were assigned in 1924. NY 17 was realigned in the 1930 renumbering of state highways in New York to follow more southerly alignments from Olean to Wellsville (via Ceres) and from Andover to Jasper (via Greenwood). As a result, NY 17 now followed the length of current NY 417 between Salamanca and Corning. and reassurance markers on NY 417 eastbound in Bolivar. The reference marker's top row reads "17" for NY 17, NY 417's original designation. As sections of the Southern Tier Expressway (STE) were completed, NY 17 was moved onto the expressway and NY 417 was assigned to sections of NY 17's former surface routing, beginning with the piece between Steamburg and Salamanca on January 1, 1970. Ironically, that first section was the first to be deleted entirely when part of the route through the Allegany Indian Reservation was closed to traffic in the early 1970s. Around the same time, NY 17 was relocated onto the mostly completed Southern Tier Expressway between Allegany and Corning, allowing the NY 417 designation to be transferred to NY 17's former alignment between the two locations. A second section—from exit 20 on the STE to US 219 in Salamanca—was added to NY 417 in the early 1980s following the completion of the STE between exits 20 and 21. The two segments were linked in the early 1990s following the completion of the expressway in the vicinity of Salamanca. Originally, NY 417 extended into Painted Post by way of a concurrency with US 15. NY 417 joined the freeway in Erwin (exit 2) and followed it north to exit 44 of the STE, where both NY 417 and US 15 ended. The overlap was eliminated sometime after 1989. The new state highway, part of US 15 and NY 17 prior to the construction of the US 15 freeway, became an extension of NY 417. In 2008, NY 417 was extended again to a new terminus at NY 415 in Painted Post following the completion of the I-86 / US 15 interchange reconstruction project. This section of NY 417 also follows part of NY 17's pre-freeway alignment. Due to this situation, NY 951T exists in two segments: a western portion extending east from NY 394 in Coldspring and a eastern portion that originates at NY 417 in Salamanca and continues west to Breed Run Road. Emergency work on the route between Breed Run and the former NY 382 began in August 2014 in an effort to make the road passable after a portion of NY 951T washed out. Replacement of the bridge and much of the closed roadway began in December 2023. ==Major intersections==
