New York State Route 417 (NY 417) is an east–weststate highway located in theSouthern Tier ofNew York in the United States. It begins at exit 20 of theSouthern Tier Expressway (Interstate 86 or I-86 andNY 17) in thecity of Salamanca and ends at a junction withNY 415 inPainted Post, west of thecity of Corning. At 105.25 miles (169.38 km) in length, NY 417 is the longest of the state highways that were formerly part of NY 17 before the construction of the Southern Tier Expressway. It also diverges the most from the current NY 17, coming within 100 feet (30 m) of thePennsylvania state line at one intersection.

In 1908, theNew York State Legislature created Route 4, an unsignedlegislative route extending across the Southern Tier fromLake Erie to theHudson River. The route followed most of what is now NY 417; however, fromOlean toWellsville and fromAndover toJasper, it followed a more northerly alignment instead. Most of Route 4 became NY 17 in 1924, and NY 17 was realigned in 1930 to follow all of modern NY 417 between Salamanca and Corning. The highway remained part of NY 17 until the 1960s and 1970s, when NY 17 was moved onto the Southern Tier Expressway as sections of the new freeway opened to traffic.

On January 1, 1970, NY 417 was assigned to NY 17's former routing betweenSteamburg and Salamanca. This section was closed to traffic soon afterward, but NY 417 was subsequently reassigned to NY 17's old alignment betweenAllegany and Corning. The remainder of the expressway between Salamanca and Allegany was completed by the early 1990s, and NY 417 was extended west to cover the highway vacated by NY 17. On its east end, NY 417 originallyoverlapped with US 15 to meet NY 17 in Painted Post. It was altered in 1997 to directly serveGang Mills via Hamilton Street and extended into Painted Post in 2008.

All of NY 417 inAllegany andSteuben counties is maintained by theNew York State Department of Transportation (NYSDOT).^[3][4] InCattaraugus County, maintenance of the route is split between NYSDOT and the cities ofOlean andSalamanca.^[5] All of NY 417 within Olean is city-maintained, save for one block of East State Street betweenNY 16 and Barry Street.^[6] To the west in Salamanca, the route is locally maintained from the junction of Clinton Street and Wildwood Avenue to the eastern city line.^[7] TheAllegany 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.^[5]

NY 417 begins at theSeneca Allegany Casino, just south of the exit 20 interchange with theSouthern Tier Expressway (I-86 andNY 17) inSalamanca, a city wholly located within the Allegany Indian Reservation. After merging with R. C. Hoag Drive (Old Route 17), the highway heads east as Broad Street, crossing through the city's business district and intersecting the south end ofNY 353 and paralleling theAllegheny River as it passes through the mostly residential central portion of the city. NY 417 changes names to Clinton Street after crossing Main Street, and subsequently intersectsU.S. Route 219 (US 219) eight blocks later at Parkway Drive (exit 21 of I-86). US 219joins NY 417 here, and the two routes head northeast across a long bridge carrying Clinton Street across the Allegheny River. On the north bank, Clinton Street merges with Wildwood Avenue, at which point US 219 and NY 417 join the latter for five blocks to a junction with Central Avenue. US 219 leaves NY 417 here, following Central Avenue out of the city while NY 417 continues east as part ofUS 219 Business.

Not far to the east of US 219, US 219 Business and NY 417 leave Salamanca upon crossing over Great Valley Creek, which serves as the boundary between Salamanca and the hamlet ofKill Buck. The concurrency continues eastward through Kill Buck and into reservation land within the bounds ofGreat Valley, transitioning to forests and otherwise undeveloped areas as the highway turns south to follow the eastern edge of the Allegheny River valley. The river, the valley, and the road all turn back to the east in the adjacent town ofCarrollton, where US 219 Business leaves NY 417 to continue south toward I-86 exit 23 and on toLimestone andBradford, Pennsylvania. NY 417 continues to follow the Allegheny River and the nearby Southern Tier Expressway (STE) to the hamlet of Vandalia, the easternmost point of the reservation. Continuing intothe town of Allegany, NY 417 indirectly intersects with I-86 and NY 17 at exist 24. From there, it passes through thevillage of Allegany and serves the campus ofSt. Bonaventure University before entering the city ofOlean, the largest community along its length.

In Olean, NY 417 initially follows State Street across a heavily commercialized area before entering a more residential portion of the city. It continues to run past a handful of smaller businesses to Olean's downtown district, where it meetsNY 16 at Union Street. East of here, NY 417 diverges from the STE as it crosses over Olean Creek and follows the Allegheny River into the slightly less populatedtown of Portville. The route continues for about 5 miles (8.0 km) to thevillage of Portville, the site of a brief concurrency withNY 305. NY 417's southeast heading continues east of the small village, taking the road away from the river and intoAllegany County.

The first 2 miles (3.2 km) of NY 417 in Allegany County traverses isolated, undeveloped areas as it runs along the base of a large valley surroundingOswayo Creek, a tributary of the Allegheny River. It continues to the small hamlet of Ceres, where NY 417 skirts thePennsylvania state line closely enough to serve as thede facto northern end ofPennsylvania Route 44, which officially begins about 100 feet (30 m) to the south of the junction. From Ceres, it turns to the northeast, utilizing a smaller valley formed by the Little Genesee Creek, itself a branch of Oswayo Creek. The 7-mile (11 km) valley leads NY 417 to thevillage of Bolivar, whereNY 275 begins at NY 417 in the village center and heads north towardFriendship.^{[citation needed]}

NY 417, meanwhile, leaves Bolivar to the east, winding its way northeastward across the mountains of theSouthern Tier to its next large community, thevillage of Wellsville. The route enters the community, located in theGenesee River valley, from the west on Bolivar Road. It runs across the northwestern part of Wellsville and crosses the Genesee River before meetingNY 19 at a junction northwest of the village's center. NY 417 turns south here, following NY 19 along a four-lanedivided highway that runs along the Genesee River and bypasses much of the village's central business district. The highway and the overlap both end just southeast of downtown Wellsville, at which point NY 417 continues northeastward through the residential eastern section of the village on Andover Road.^{[citation needed]}

About 2 miles (3.2 km) from the village center, the development along NY 417 ceases as the route progresses generally northeastward through the narrow valley of Dyke Creek, closely paralleling themain line of theWestern New York and Pennsylvania Railroad (WNYP). After another 7 miles (11 km), NY 417 comes to thevillage of Andover, whereNY 21 begins its long trip north toward theFinger Lakes. The WNYP also heads north here to follow NY 21 to the city ofHornell; however, NY 417 continues east along Dyer Creek for another 2 miles (3.2 km) to theSteuben County line.^{[citation needed]}

In Steuben County, NY 417 begins to climb theheadwall of the Dyer Creek valley, reaching an elevation of 2,300 feet (701 m) above sea level at theGreenwood hamlet of West Greenwood. The route descends into a ravine known as Cole Hollow shortly afterward,^[8] where it intersectsNY 248 north of the hamlet of Greenwood.^{[citation needed]} Past NY 248, the route winds its way through Woodward Hollow^[8] to the town ofJasper and a junction withNY 36, another major north–south route, at a junction west of the hamlet of Jasper. NY 36 overlaps with NY 417 to the outskirts of the community, at which point it splits from NY 417 and heads toward Hornell. NY 417, meanwhile continues southeast through Jasper and follows Tuscarora Creek towardWoodhull.^{[citation needed]}

Beyond Jasper, the road meanders through a valley surrounding Tuscarora Creek, heading generally eastward to a larger gully containing theCanisteo River and thevillage of Addison. Just north of the village center, the route crosses over the river and intersects Front Street,^{[citation needed]} which once carriedNY 17F and laterNY 432 into the village.^[9][10] Outside of Addison, NY 417 follows the Canisteo River and theNorfolk Southern Railway'sSouthern Tier Line into the adjacent town ofErwin, where it connects toI-99 andUS 15 at an interchange northwest of theconfluence of the Canisteo andTioga Rivers. At this point, the railroad and NY 417 turn northeast to follow I-99/US 15 and the Tioga River into the hamlet ofGang Mills, a western suburb ofCorning.^{[citation needed]}

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 theCohocton River and reconnecting to the Southern Tier Expressway at exit 44, a complexsemi-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 ofPainted Post as North Hamilton Street, serving two blocks of mostly commercial properties before terminating at an intersection withNY 415.^{[citation needed]}

Three sections of modern NY 417 were designated as part of Route 4, an unsignedlegislative route, by theNew York State Legislature in 1908. Route 4, a cross-state highway that began nearLake Erie inChautauqua County and ended near theHudson River inOrange County, proceeded east fromSalamanca toCorning viaOlean,Hinsdale,Belvidere,Wellsville,Andover,Hornell,Jasper, andAddison.^[11][12] Much of legislative Route 4 west ofHarriman—including all of the route between Salamanca and Corning—was designated as part ofNY 17 when the first set of posted routes inNew York were assigned in 1924.^[13][14] NY 17 was realigned in the1930 renumbering of state highways in New York to follow more southerly alignments from Olean to Wellsville (viaCeres) and from Andover to Jasper (viaGreenwood). As a result, NY 17 now followed the length of current NY 417 between Salamanca and Corning.^[15]

As sections of theSouthern 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 betweenSteamburg and Salamanca on January 1, 1970.^[2] Ironically, that first section was the first to be deleted entirely when part of the route through theAllegany 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 betweenAllegany and Corning, allowing the NY 417 designation to be transferred to NY 17's former alignment between the two locations.^[16][17] A second section—from exit 20 on the STE toUS 219 in Salamanca—was added to NY 417 in the early 1980s following the completion of the STE between exits 20 and 21.^[18][19] The two segments were linked in the early 1990s following the completion of the expressway in the vicinity of Salamanca.^[10][20]

Originally, NY 417 extended into Painted Post by way of aconcurrency withUS 15. NY 417 joined the freeway inErwin (exit 2) and followed it north to exit 44 of the STE, where both NY 417 and US 15 ended.^[21][22] The overlap was eliminated sometime after 1989.^[20] On April 1, 1997, ownership and maintenance of Hamilton Street from the east end of NY 417 at US 15 exit 2 to US 15 exit 4 inGang Mills was transferred from the town of Erwin to the state of New York as part of a highway maintenance swap between Erwin, the state, andSteuben County.^[23] The new state highway, part of US 15 and NY 17 prior to the construction of the US 15 freeway,^[24] became an extension of NY 417.^[25] In 2008, NY 417 was extended again to a new terminus atNY 415 inPainted Post following the completion of the I-86 / US 15 interchange reconstruction project.^{[citation needed][26]} This section of NY 417 also follows part of NY 17's pre-freeway alignment.^[24]

The portion of former NY 417 from Steamburg to Salamanca is now designated as NY 951T, an unsignedreference route. Although the physical roadway remains continuous, part of it is closed to traffic. Ostensibly, this was due to the potential for theAllegheny Reservoir to flood and inundate part of the roadway; the closure may have also partially been invoked to discourage tourists from browsing the newly built Seneca resettlement area (Jimerson Town) that had been constructed around the road. This stretch was abandoned in 1980 and left unattended by both the state and local governments, leading to the rapid deterioration of the roadway, including a bridge running over the reservoir (constructed in 1930) that remains standing but has since become a hazard.^[27] Due to this situation, NY 951T exists in two segments: a 0.47-mile (0.76 km) western portion extending east fromNY 394 inColdspring and a 3.55-mile (5.71 km) eastern portion that originates at NY 417 inSalamanca and continues west to Breed Run Road.^[1] TheSeneca Nation Allegany reservation governmental headquarters, along with the surrounding hamlet of Jimerson Town, lies on the eastern half of NY 951T.^{[citation needed]} The Seneca Nation and the state of New York began talks in March 2010 to rebuild the former NY 417 between Steamburg and Jimerson Town. At the time, the cost was estimated to be $15 million. Discussions were revived again in April 2012 after the death of a woman attempting to cross the bridge with her husband.^[27] In April 2014, the state announced that it was indeed planning a project to replace the bridge and reopen the roadway.^[28] Emergency work on the route between Breed Run and the formerNY 382 began in August 2014 in an effort to make the road passable after a portion of NY 951T washed out.^[29] Replacement of the bridge and much of the closed roadway began in December 2023.^[30]
