'''New York State Route&nbsp;17''' ('''NY&nbsp;17''') is a major [[state highway]] that extends for {{convert|397|mi|2}} through the [[Southern Tier]] and [[Downstate New York|Downstate]] regions of [[New York (state)|New York]] in the United States. It begins at the [[New York–Pennsylvania border|Pennsylvania state line]] in [[Mina, New York|Mina]] and runs east as a [[limited-access highway]], following the '''Southern Tier Expressway''' to [[Binghamton]] and the '''Quickway''' from Binghamton east to [[Woodbury, Orange County, New York|Woodbury]]. At Woodbury, the route turns south to become a [[arterial road|local arterial]], eventually following the '''Orange Turnpike''' to the [[New Jersey]] state line near [[Suffern, New York|Suffern]]. The portion of NY&nbsp;17 west of Woodbury is in the process of being upgraded to [[Interstate 86 (Pennsylvania–New York)|Interstate&nbsp;86]], and as of February 2025, the routes are [[concurrency (road)|concurrent]] from the Pennsylvania border to [[Vestal, New York|Vestal]] and from [[Kirkwood, New York|Kirkwood]] to [[Windsor (village), New York|Windsor]].

At {{convert|397|mi|km}}, NY&nbsp;17 is the longest state route in New York, and is the second-longest highway of any kind in the state, behind only the [[New York State Thruway]]. It serves 11 counties, passes through the cities of [[Salamanca (city), New York|Salamanca]], [[Olean (city), New York|Olean]], [[Corning, New York|Corning]], [[Elmira, New York|Elmira]], and Binghamton, and enters the vicinity of several others, including [[Jamestown, New York|Jamestown]] and [[Middletown, Orange County, New York|Middletown]]. As it proceeds across the state, it intersects many of New York's major [[Interstate Highway|Interstate]] and [[U.S. Highway]]s, including [[U.S. Route 219 in New York|U.S. Route&nbsp;219]] (US&nbsp;219) in Salamanca, [[Interstate 390|I-390]] in [[Avoca, New York|Avoca]], [[Interstate 99 in New York|I-99]] and [[U.S. Route 15 in New York|US&nbsp;15]] near Corning, [[Interstate 81 in New York|I-81]] and [[U.S. Route 11 in New York|US&nbsp;11]] in Binghamton, [[Interstate 84 in New York|I-84]] and [[U.S. Route 6 in New York|US&nbsp;6]] near Middletown, and [[Interstate 87 (New York)|I-87]] in Woodbury. Aside from a brief concurrency with the Thruway near [[Hillburn, New York|Hillburn]], the route is maintained by the [[New York State Department of Transportation]], including a portion in the vicinity of [[Waverly (village), New York|Waverly]] that is physically located in Pennsylvania.

Initially part of an [[auto trail]] called the [[Liberty Highway]], the route was added to the state highway system in 1924, extending from [[Westfield (village), New York|Westfield]] to Suffern via at-grade highways. As traffic demand surged, it was moved onto the Quickway and the Southern Tier Expressway as limited-access sections of both were completed from the 1950s to the 1990s. In 1998, all of NY&nbsp;17 between the Pennsylvania state line and Woodbury was designated as "Future I-86". The westernmost {{convert|177|mi|0}} of the route was designated as I-86 one year later, and the designation has been gradually extended eastward as sections of NY&nbsp;17 were improved to Interstate Highway standards. Prior to the I-86 designation, NY&nbsp;17 was part of a multi-state Route 17 along with [[New Jersey Route 17]] and the former Pennsylvania Route 17.

===Pennsylvania to Elmira===
[[File:Southern Tier Expressway.svg|100px|right|thumb|Route marker used along the Southern Tier Expressway]]
{{Main|Interstate 86 (Pennsylvania&ndash;New York)}}
NY&nbsp;17 begins as a [[controlled-access highway|freeway]] at the point where I-86 crosses the [[New York–Pennsylvania border]] in [[Mina, New York|Mina]], [[Chautauqua County, New York|Chautauqua County]]. I-86 heads westward from there to its western terminus at [[Interstate 90 in Pennsylvania|I-90]]. I-86 and NY&nbsp;17 continue eastward through the [[Southern Tier]], encountering [[New York State Route 426|NY&nbsp;426]] (exit&nbsp;4) a short distance from the state line prior to meeting [[New York State Route 76|NY&nbsp;76]] (exit&nbsp;6) south of [[Sherman (village), New York|Sherman]]. East of exit&nbsp;8 ([[New York State Route 394|NY&nbsp;394]]), I-86 and NY&nbsp;17 cross [[Chautauqua Lake]] and follow the lake shore eastward to [[Jamestown, New York|Jamestown]], where it connects to [[New York State Route 60|NY&nbsp;60]] at exit&nbsp;12 due north of the city. East of the city, the freeway meets [[U.S. Route 62 in New York|US&nbsp;62]] at exit&nbsp;14 and is joined by the old [[Erie Railroad]] line, which parallels the freeway as it heads across southern New York.

Between exits&nbsp;17 and&nbsp;18 ([[New York State Route 280|NY&nbsp;280]]), I-86 and NY&nbsp;17 cross the [[Allegheny Reservoir]] near its northernmost extent. Past NY&nbsp;280, the freeway runs adjacent to the northern extent of the [[Allegany State Park]] and follows the reservoir and the connecting [[Allegheny River]] eastward to [[Salamanca (city), New York|Salamanca]]. Near downtown Salamanca, I-86 and NY&nbsp;17 meet [[U.S. Route 219 in New York|US&nbsp;219]] (exit&nbsp;21). US&nbsp;219 joins the freeway east to exit&nbsp;23 near [[Carrollton, New York|Carrollton]], where it splits from I-86 and NY&nbsp;17 and heads toward [[Bradford, Pennsylvania]], forming the eastern edge of the state park as it heads south. Meanwhile, the freeway continues east to [[Olean, New York|Olean]], where it meets [[New York State Route 417|NY&nbsp;417]] (a previous alignment of NY&nbsp;17) at exit&nbsp;24 west of town and [[New York State Route 16|NY&nbsp;16]] (exit&nbsp;27) north of the area.

Past Olean, the route drifts northward away from Pennsylvania toward [[Hornell, New York|Hornell]], where I-86 and NY&nbsp;17 intersect [[New York State Route 36|NY&nbsp;36]] (exit&nbsp;34). To the east in [[Avoca (village), New York|Avoca]], the Southern Tier Expressway meets [[Interstate 390|I-390]] at exit&nbsp;36. I-86 and NY&nbsp;17 southeast from the junction, passing through [[Bath (village), New York|Bath]] on its way an interchange with [[Interstate 99|I-99]] and [[U.S. Route 15 in New York|US&nbsp;15]] in [[Painted Post, New York|Painted Post]] (exit&nbsp;44). Here, I-99 and US&nbsp;15 begin and head south toward Pennsylvania, while I-86 and NY&nbsp;17 continue east through [[Corning (city), New York|Corning]] to the city of [[Elmira, New York|Elmira]].

===Elmira to Harriman===
[[File:State border sign on NY 17.jpg|thumb|left|Sign along eastbound NY&nbsp;17 marking return to New York after its brief foray into Pennsylvania]]
From Elmira to Binghamton, NY&nbsp;17, the Erie Railroad (now operated by [[Norfolk Southern]] as the [[Southern Tier Line]]), and its old alignments generally stay close together. They follow the Chemung River to exit&nbsp;60 ([[U.S. Route 220|US&nbsp;220]] in [[South Waverly, Pennsylvania]]) and the [[Susquehanna River]] from east of exit&nbsp;61 ([[Waverly, Tioga County, New York|Waverly, New York]]) to Binghamton; on the latter section, both [[New York State Route 17C|NY&nbsp;17C]] and [[New York State Route 434|NY&nbsp;434]] are old NY&nbsp;17. Between the two rivers, which intersect in Pennsylvania, the general corridor runs just north of the state line in New York. NY&nbsp;17 itself crosses into Pennsylvania for approximately {{convert|1|mi|km}} between a point west of exit&nbsp;60 and a point west of exit&nbsp;61; additionally, all the ramps at exit&nbsp;60 and portions of the eastbound ramps at exits&nbsp;59A and&nbsp;61 are in Pennsylvania. Despite being in Pennsylvania, it is still signed as NY&nbsp;17, and these roadways are still maintained by the [[New York State Department of Transportation]].<ref>{{cite web |url = http://www.gribblenation.com/hfotw/exit_25.html |title = NY&nbsp;17 Waverly, NY/South Waverly, PA |date = September 26, 1998 |first = Michael G. |last = Koerner |work = Highway Feature of the Week |publisher = Gribblenation.net |access-date = May 8, 2010 |archive-date = May 24, 2011 |archive-url = https://web.archive.org/web/20110524152412/http://www.gribblenation.com/hfotw/exit_25.html |url-status = dead }}{{self-published inline|certain=yes|date=October 2022}}</ref><ref>{{cite map |publisher = [[Pennsylvania Department of Transportation]] |title = General Highway Map – Bradford County, Pennsylvania |url = http://www.dot7.state.pa.us/BPR_pdf_files/Maps/GHS/Roadnames/Bradford_GHSN.PDF |year = 2015 |access-date = December 25, 2015 |format = PDF }} The Southern Tier Expressway is marked with circular shields instead of keystones and labeled "NY&nbsp;17" instead of just "17".</ref> At the Tioga County line near Waverly, I-86 temporarily terminates as NY&nbsp;17 continues eastward toward [[Binghamton (city), New York|Binghamton]].

Near downtown Binghamton, NY&nbsp;17 goes around the side of Prospect Mountain at what is locally known as "[[kamikaze]] curve".<ref>[http://wikimapia.org/26393740/Kamikaze-Curve "Kamikaze Curve - Binghamton, New York"]</ref> Heading eastbound, the freeway curves sharply left around the hillside, splits into ramps to [[Interstate 81 in New York|I-81]] north and south, and curves right to merge into I-81 south as it passes over the [[Chenango River]]. From that point east and southeast about {{convert|5|mi|km}}, I-81 and NY&nbsp;17 run [[concurrent (road)|concurrently]]. NY&nbsp;17 splits from I-81, the Erie Railroad and the Susquehanna River to the east into [[Stilson Hollow]]; from this split (exit&nbsp;75) to its end, most of NY&nbsp;17 does not follow the Erie Railroad, which crosses into Pennsylvania several times.

At the end of Stilson Hollow, NY&nbsp;17 heads over a summit and into the valley formed by the [[Occanum Creek]]. The creek empties into the [[Susquehanna River]] at [[Windsor (village), New York|Windsor]] (exit&nbsp;79), which NY&nbsp;17 follows southeast to [[Damascus, New York|Damascus]] (exit&nbsp;80) before turning northeast along [[Tuscarora Creek (New York)|Tuscarora Creek]]. It soon turns east and southeast over a summit, rejoining the [[Erie Railroad]] just north of [[Gulf Summit, New York|Gulf Summit]]. The highway and railroad head east along <!--some creek and-->[[Oquaga Creek]] to [[Deposit (village), New York|Deposit]] (exit&nbsp;84), where they turn southeast along the [[West Branch Delaware River]], where NY&nbsp;17 briefly becomes an arterial road. A gap in the freeway stretches from here to just short of [[Hancock (village), New York|Hancock]] (exit&nbsp;87), the place the West Branch joins with the [[East Branch Delaware River]]. The Erie Railroad continues southeast along the combined [[Delaware River]], while NY&nbsp;17 turns east along the valley formed by the East Branch, either closely following or built directly over the abandoned [[New York, Ontario and Western Railway]]<ref>{{cite web |first = Bill |last = Schneider |date = n.d. |url = http://home.comcast.net/~oandw/relics4.htm |title = To the Mountains… 50 Years Later |work = The Old Woman in the Back Bedroom |archive-url = https://web.archive.org/web/20121103164151/http://home.comcast.net/~oandw/relics4.htm |archive-date = November 3, 2012 }}{{self-published inline|certain=yes|date=October 2022}}</ref> to [[Liberty (village), New York|Liberty]].

At [[East Branch, New York|East Branch]] (exit&nbsp;90), the East Branch Delaware River turns north, and NY&nbsp;17 continues east with the [[Beaver Kill]] to [[Roscoe, New York|Roscoe]] (exit&nbsp;94), [[Willowemoc Creek]] to [[Livingston Manor, New York|Livingston Manor]] (exit&nbsp;96), and [[Little Beaver Kill]] to [[Parksville, New York|Parksville]] (exit&nbsp;98). The highway and parallel NYO&W pass south over a summit to [[Liberty (village), New York|Liberty]] (exits&nbsp;99–100), and continue along the [[Middle Mongaup River]] to [[Ferndale, New York|Ferndale]] (exit&nbsp;101). The NYO&W turned east there, but NY&nbsp;17 continues south over a summit and into the [[Spring Brook (New York)|Spring Brook]] and [[East Mongaup River]] valleys past [[Harris, New York|Harris]] (exit&nbsp;102). NY&nbsp;17 then cuts southeast cross-country to [[Monticello, New York|Monticello]] (exit&nbsp;104; passing [[Monticello Raceway]]) and beyond, following the old [[Newburgh and Cochecton Turnpike]] (old NY&nbsp;17) to [[Bloomingburg, New York|Bloomingburg]] (exit&nbsp;116). The old [[Middletown and Wurtsboro Turnpike]], also old NY&nbsp;17, and partially [[New York State Route 17M|NY&nbsp;17M]], runs south to [[Middletown, Orange County, New York|Middletown]], which NY&nbsp;17 cuts cross-country to bypass to the east, rejoining NY&nbsp;17M&nbsp;&ndash; and the main line of the [[Erie Railroad]]&nbsp;&ndash; at [[Goshen (village), New York|Goshen]] (exit&nbsp;123). NY&nbsp;17, its old former alignment (NY&nbsp;17M) and the Erie run generally east-southeast, partly cross-country and partly through small stream valleys, to the end of the freeway, the directional change in NY&nbsp;17 from east&ndash;west to north&ndash;south, and the junction of the Erie with its branch to [[Newburgh, New York|Newburgh]].

===Harriman to New Jersey===
NY&nbsp;17 heads southwest from the Quickway as a surface road, passing through the village of [[Woodbury, Orange County, New York|Woodbury]] before entering the village of [[Harriman, New York|Harriman]], where it intersects with the eastern terminus of NY&nbsp;17M.<ref name="HarrimanNJ">{{Google maps|url=https://maps.google.com/maps?f=d&source=s_d&saddr=RT-17+%4041.313118,+-74.138590&daddr=Korean+War+Veterans+Memorial+Hwy%2FRT-17%2FRT-59+%4041.134835,+-74.166591+to:I-287+S%2FRT-17+S+%4041.117661,+-74.161818+to:41.11285,-74.162753&hl=en&geocode=FV5jdgIdIryU-w%3BFfOqcwIdwU6U-w%3BFd1ncwIdZmGU-w%3B&mra=mi&mrcr=2&mrsp=3&sz=18&sll=41.113071,-74.16214&sspn=0.002971,0.006958&ie=UTF8&ll=41.131284,-74.158916&spn=0.047516,0.111322&t=h&z=14 |title= Overview Map of NY&nbsp;17 from Harriman to New Jersey |access-date=January 20, 2008}}</ref> As the route heads southward from this junction, its signage changes from being east or west to north or south. The route parallels the Thruway as it proceeds through a disjointed piece of [[Harriman State Park (New York)|Harriman State Park]] and enters the town of [[Tuxedo, New York|Tuxedo]]. While inside the park, NY&nbsp;17 intersects [[Arden Valley Road]], a parkway that connects to [[Seven Lakes Drive]] deep inside the park.<ref name="map4">{{cite map |author = The New York–New Jersey Trail Conference |title = Harriman–Bear Mountain Trail Maps |at = Map 4 |publisher = The New York–New Jersey Trail Conference |year = 2005 }}</ref> South of Arden Valley Road, NY&nbsp;17 briefly exits Harriman State Park and enters the hamlet of [[Southfields, New York|Southfields]], where it intersects with [[County Route 19 (Orange County, New York)|County Route&nbsp;19]] (CR&nbsp;19) and passes by the [[Red Apple Rest]], a former restaurant and roadside attraction.<ref name="map3" />

Past the hamlet, the route heads back into the park and intersects with [[New York State Route 17A|NY&nbsp;17A]] and [[County Route 106 (Orange County, New York)|CR&nbsp;106]] near the park's western boundary. South of the junction, NY&nbsp;17 leaves the park and proceeds through a lightly populated area to the village of [[Tuxedo Park, New York|Tuxedo Park]]. At the Tuxedo Park train station is access to some hiking trails in Harriman State Park.<ref name="map3">{{cite map |author = The New York–New Jersey Trail Conference |title = Harriman–Bear Mountain Trail Maps |at = Map 3 |publisher = The New York–New Jersey Trail Conference |year = 2005 }}</ref> The route continues on, paralleling the Thruway into [[Rockland County, New York|Rockland County]]. On the other side of the county line, NY&nbsp;17 enters the village of [[Sloatsburg, New York|Sloatsburg]], where it meets [[Seven Lakes Drive]] and connects to [[County Route 72 (Rockland County, New York)|CR&nbsp;72]] by way of a modified trumpet interchange.<ref name="HarrimanNJ"/>

Outside of Sloatsburg, NY&nbsp;17 becomes a four-lane [[limited-access road|expressway]] and winds its way southeasterly along the [[Ramapo River]] and the Thruway through the town of [[Ramapo, New York|Ramapo]] to the hamlet of the same name, based just north of NY&nbsp;17's junction with [[New York State Route 59|NY&nbsp;59]]. Here, NY&nbsp;17 turns to the southwest, merging onto the Thruway southbound at exit&nbsp;15A, traversing a sparsely developed area of the village of [[Hillburn, New York|Hillburn]]. About {{convert|0.75|mi|2}} south of merging onto the Thruway, NY&nbsp;17 passes to the south of the village center as it approaches [[Interstate 287|I-287]]. At exit 15A for [[New Jersey]], NY&nbsp;17 leaves the Thruway and merges with I-287 southbound and proceeds to the New Jersey state line, where it connects to New Jersey's [[New Jersey Route 17|Route&nbsp;17]].<ref name="HarrimanNJ"/> An old alignment of NY&nbsp;17 in Hillburn, now called Old Route 17 used to go around the Thruway instead of merging onto it.

==History==

===Origins===

==== Before the automobile ====
[[File:Map of Liberty Highway.png|thumb|400px|right|Map of the Liberty Highway]]
From Binghamton to Corning, NY&nbsp;17 follows the course of the Great Bend and Bath Turnpike, which was legislated in 1808 to continue the [[Pennsylvania Route 371|Cochecton and Great Bend Turnpike]] (US&nbsp;11) through the Susquehanna Valley. The road ran from the Pennsylvania state line at Great Bend through Binghamton, Owego, and Elmira to Bath. In its day, it was a major route of travel through the Susquehanna Valley.<ref>{{Cite book|last=Lawyer|first=William S|url=https://books.google.com/books?id=E9YwAQAAMAAJ|title=Binghamton : its settlement, growth and development, and the factors in its history, 1800-1900|publisher=Century Memorial Publishing Co|year=1900|pages=267}}</ref> Today, the road is designated US&nbsp;11 from Pennsylvania to Binghamton, then NY&nbsp;17C to Waverly, NY&nbsp;352 into Corning, and NY&nbsp;415 to Bath. The at-grade sections of NY&nbsp;17 in Orange County follow the Orange Turnpike south of Southfields and the New Windsor and Cornwall Turnpike to its north.

==== Liberty Highway and Legislative Route 4 ====
The original routing of NY&nbsp;17, from [[Westfield (village), New York|Westfield]] to [[Harriman, New York|Harriman]], was largely designated in 1908 by the [[New York State Legislature]] as Route&nbsp;4, an unsigned [[legislative route]]. This routing was incorporated in 1918 as the main portion of an [[auto trail]] called the [[Liberty Highway]], which connected [[New York City]] to [[Cleveland]] via [[Hackensack, New Jersey|Hackensack]], [[Liberty (town), New York|Liberty]], the [[Southern Tier]], and [[Erie]].<ref>{{cite magazine |last = Johnston |first = R. J. |title = The Liberty Highway: Touring and Driveaway Route Between Cleveland and New York |magazine = Motor Age |date = April 4, 1918 |volume = 33 |issue = 14 |pages = 72–75 |url = https://books.google.com/books?id=vVgfAQAAMAAJ |access-date = January 17, 2013 }}</ref>

Legislative Route&nbsp;4 began at legislative Route&nbsp;18 (current [[U.S. Route 20 in New York|US&nbsp;20]]) in Westfield and proceeded southeast through [[Mayville, New York|Mayville]] to [[Jamestown, New York|Jamestown]] on what is now [[New York State Route 394|NY&nbsp;394]] and [[New York State Route 430|NY&nbsp;430]]. From there, the route headed generally eastward to [[Salamanca (city), New York|Salamanca]] over modern NY&nbsp;394, [[New York State Route 242|NY&nbsp;242]], and [[New York State Route 353|NY&nbsp;353]], and southeast to [[Olean, New York|Olean]] via [[New York State Route 417|NY&nbsp;417]]. At Olean, the route shifted northward, passing through [[Hinsdale, New York|Hinsdale]], [[Friendship, New York|Friendship]], and [[Belvidere, New York|Belvidere]] on current [[New York State Route 16|NY&nbsp;16]], [[New York State Route 446|NY&nbsp;446]] and Allegany County's [[County Route 20 (Allegany County, New York)|CR&nbsp;20]] before returning southward on what is now [[New York State Route 19|NY&nbsp;19]] to access the village of [[Wellsville (village), New York|Wellsville]].<ref name="1909book">{{cite book |url = https://books.google.com/books?id=jZ0AAAAAMAAJ&pg=PA54 |author = State of New York Department of Highways |title = The Highway Law |year = 1909 |publisher = J.

[[File:SR 17 NY.jpg|thumb|left|NY&nbsp;17 at Liberty, New York]]
From Wellsville to [[Andover (village), New York|Andover]] and from [[Jasper, New York|Jasper]] to [[Corning (city), New York|Corning]], Route&nbsp;4 followed modern NY&nbsp;417. In between Andover and Jasper, however, Route&nbsp;4 veered north on current [[New York State Route 21|NY&nbsp;21]] and [[New York State Route 36|NY&nbsp;36]] to serve [[Hornell, New York|Hornell]]. East of Corning, the alignment of legislative Route&nbsp;4 ran along the Great Bend and Bath Turnpike, and more closely resembled the modern alignments of the Southern Tier Expressway and the Quickway. Route&nbsp;4 exited Corning on what is now [[New York State Route 352|NY&nbsp;352]] and followed it to [[Big Flats (CDP), New York|Big Flats]], where it broke from NY&nbsp;352 and proceeded to [[Horseheads (village), New York|Horseheads]] on Chemung CR&nbsp;64 and to [[Elmira (city), New York|Elmira]] on what is now Lake Road, Madison Avenue and the east end of [[New York State Route 352|NY&nbsp;352]]. Between Elmira and [[Binghamton (city), New York|Binghamton]], Route&nbsp;4 followed either local roads that were bypassed or upgraded into the Southern Tier Expressway, namely modern NY&nbsp;17 and Chemung and Tioga CR&nbsp;60 from Elmira to [[Waverly, Tioga County, New York|Waverly]], [[New York State Route 17C|NY&nbsp;17C]] between Waverly and [[Owego (village), New York|Owego]], [[New York State Route 434|NY&nbsp;434]] from Owego to [[Vestal, New York|Vestal]], and NY&nbsp;17C and Riverside Drive (via [[New York State Route 26|NY&nbsp;26]]) from Vestal to Binghamton.<ref name="1909book" /><ref name="1920book" />

Route&nbsp;4 exited the city on [[U.S. Route 11 in New York|US&nbsp;11]] and followed it to Kirkwood Center, a hamlet adjacent to the eastern junction of NY&nbsp;17 and [[Interstate 81 in New York|I-81]]. From this point to Harriman, except for one section near [[Middletown, Orange County, New York|Middletown]], the path Route&nbsp;4 followed became the basis for the Quickway several decades later. Between Kirkwood Center and Hancock, Route&nbsp;4 utilized what was later upgraded into the Quickway (via Broome CR&nbsp;28 from [[Windsor (town), New York|Windsor]] to [[Deposit (village), New York|Deposit]]). East of here, it used parallel roads instead: modern "Old Route&nbsp;17" (Delaware CR&nbsp;17 and Sullivan CRs&nbsp;179A to&nbsp;174) from Deposit to [[Monticello, New York|Monticello]], Sullivan CRs&nbsp;173 to&nbsp;171 between Monticello and [[Bloomingburg, New York|Bloomingburg]], and Orange CR&nbsp;76 and [[New York State Route 17M|NY&nbsp;17M]] from Bloomingburg to Harriman. At Harriman, Route&nbsp;4 broke from the Liberty Highway and proceeded northeast over current [[U.S. Route 6 in New York|US&nbsp;6]] and [[New York State Route 293|NY&nbsp;293]] to [[Highland Falls, New York|Highland Falls]], where it ended at legislative Route&nbsp;3 (modern [[U.S. Route 9W|US&nbsp;9W]]).<ref name="1909book" /><ref name="1920book" /> The portion of the Liberty Highway between [[Suffern, New York|Suffern]] and Harriman became part of legislative Route&nbsp;39-b in 1911;<ref name="1920book" /><ref name="1919book">{{cite book |url = https://books.google.com/books?id=hZ4AAAAAMAAJ&pg=PA87 |author = State of New York Commission of Highways |title = The Highway Law |year = 1919 |publisher = J.

In the [[1930 state highway renumbering (New York)|1930 renumbering of state highways in New York]], NY&nbsp;17 basically remained intact. The only changes made at this time were the straightening out of the Olean–Wellsville segment (now via [[Ceres, New York|Ceres]]) and the Andover–Jasper segment (now via [[Greenwood, New York|Greenwood]]).<ref name="1930nyt">{{cite news |last = Dickinson |first = Leon A. |title = New Signs for State Highways |newspaper = The New York Times |date = January 12, 1930 |page = 136 }}</ref>

NY&nbsp;17 initially reached New Jersey by way of Suffern's Orange Avenue (now [[U.S. Route 202 in New York|US&nbsp;202]]) and connected to New Jersey's [[New Jersey Route 2|Route&nbsp;2]] at the state line. In 1932, an alternate route of NY&nbsp;17 between the New Jersey state line at [[Hillburn, New York|Hillburn]] and the hamlet of [[Ramapo, New York|Ramapo]] on the western bank of the [[Ramapo River]] was designated as [[New York State Route 59#Designation|NY&nbsp;339]]. The route largely followed the path of modern [[Interstate 287|I-287]] and the [[New York State Thruway]] between the two locations. It initially became a local road upon crossing into New Jersey;<ref>{{cite map |title = Texaco Road Map – New York |author = [[Texas Oil Company]] |year = 1932 |author2 = Rand McNally and Company |publisher = Texas Oil Company }}</ref> however, Route&nbsp;2 was realigned {{circa|1933}} to connect to NY&nbsp;339 instead of NY&nbsp;17.<ref>{{cite map |title = Texaco Road Map – New York |author = Texas Oil Company |year = 1933 |author2 = Rand McNally and Company |publisher = Texas Oil Company }}</ref>

In the mid-1930s, the alignments of NY&nbsp;17 and NY&nbsp;339 south of Ramapo were flipped, placing NY&nbsp;17 on the western route.<ref>{{cite map |title = Texaco Road Map – New York |author1 = Texas Oil Company |year = 1934 |author2 = Rand McNally and Company |publisher = Texas Oil Company }}</ref><ref>{{cite map |title = Road Map – Metropolitan New York and Long Island |author1 = [[Shell Oil Company]] |year = 1936 |author2 = [[H.M. Gousha Company]] |publisher = Shell Oil Company }}</ref>

In 1938, NY&nbsp;17 was relocated onto a new highway through the Hillburn village limits. While the southern half of the new road utilized the old highway, the northern half veered to the west of both Hillburn and old NY&nbsp;17, bypassing the village before rejoining the old road south of Ramapo.<ref>{{cite map |title = New York–New Jersey – Ramapo Quadrangle (southwestern portion) |author = [[United States Geological Survey]] |year = 1938 |scale = 1:62,500 |location = Reston, Virginia |publisher = United States Geological Survey |access-date = May 8, 2010 |url = http://docs.unh.edu/NY/ramp38sw.jpg |archive-date = July 4, 2010 |archive-url = https://web.archive.org/web/20100704235712/http://docs.unh.edu/NY/ramp38sw.jpg |url-status = dead }}</ref>

===Late 20th century conversion into expressway and later improvements===
{{Main|Interstate 86 (Pennsylvania&ndash;New York)}}
The explosive growth of the [[tourism]] industry in the [[Catskill Mountains]] region, which began in the 1930s and intensified after [[World War II]], stretched the rural road to its limits. Scores of hotels, resorts and bungalow colonies attracted hundreds of thousands of vacationing New Yorkers, whose cars left the two-lane NY&nbsp;17 hopelessly jammed in summer. Many towns, especially the fairly large city of [[Middletown, Orange County, New York|Middletown]], were paralyzed on Friday evenings and Sunday afternoons in the summertime, as traffic passed through local downtowns and their traffic lights.<ref>{{cite news |url = https://query.nytimes.com/gst/fullpage.html?res=990DE4DF113BF933A0575BC0A96F958260 |title = Empty Tables and Full Memories; Lines Are Gone at Fabled Cafeteria on Way to Catskills |newspaper = The New York Times |date = August 30, 1999 |last = Berger |first = Joseph |access-date = December 18, 2007 |quote = On a Friday night at the sweltering height of summer, cars would lumber up in an unbroken stream, their radiators already gurgling steam from two hours of stop-and-go driving along the two-lane morass of Route 17 &ndash; mocked by exasperated World War II veterans as ''the Burma Road.'' Out would spill dozens of Irvs, Sams and Murrays, drained from a week of muscular work and lonely for their wives and children up in the bungalows in places like Swan Lake and Monticello. }}</ref> In addition, the tight turns and steep inclines along the route led to numerous fatal crashes, including two milk tanker truck crashes in the mid-1950s. In response, [[New York State]] officials planned a four-lane replacement, the first free long-distance expressway in the state and one of the earliest in the United States. It would replace intersections with well-spaced access ramps, separate grades with [[Overpass|flyovers]], and allow safe travel at up to {{convert|65|mi/h|km/h}}.<ref name="1958nyt">{{cite news |last = Ingraham |first = Joseph C. |title = Paving the Way to the Catskills |newspaper = The New York Times |date = October 19, 1958 }}</ref>
[[File:Old_NY_17_through_Red_House.jpg|left|thumb|NY&nbsp;17's former alignment in the town of [[Red House, New York|Red House]], abandoned and banned from traffic]]
The first segment of the new highway extended from [[Fair Oaks, New York|Fair Oaks]] to [[Goshen (village), New York|Goshen]], bypassing the city of Middletown to the northeast. It opened to traffic in July 1951 as a realignment of NY&nbsp;17.<ref name="1958nyt" /><ref name="1952map">{{cite map |title = New York |author = [[Sunoco]] |author2 = Rand McNally and Company |publisher = Sunoco |year = 1952 }}</ref> As more sections of the freeway—known as the Quickway—opened up during the 1950s and 1960s, NY&nbsp;17 was moved onto them.

At the time, NY&nbsp;17 followed the entirety of two of the four open sections ([[Steamburg, New York|Steamburg]] to Salamanca and Owego to the [[Broome County, New York|Broome County]] line) and part of a third (Corning to Lowman via Elmira).<ref name="1968map" /><ref name="1965map">{{cite map |title = New York |author = [[Mobil]] |author2 = Rand McNally and Company |publisher = Mobil |year = 1965 }}</ref>

As more continuous pieces of the expressway opened during the 1970s, NY&nbsp;17 was realigned onto them, with much of NY&nbsp;17's old alignment becoming NY&nbsp;394, NY&nbsp;417, or NY&nbsp;17C. By 1980, the expressway was complete from [[Bemus Point, New York|Bemus Point]] to Binghamton except for two areas near Salamanca and Corning. Although NY&nbsp;17 continued to extend northwestward along its original alignment from Bemus Point to Westfield, both highways were also designated as parts of NY&nbsp;430 and NY&nbsp;394 in anticipation of the completion of the Southern Tier Expressway west of [[Chautauqua Lake]], which NY&nbsp;17 would be rerouted to follow.<ref name="1972map">{{cite map |title = New York and New Jersey Tourgide<!--sic--> Map |author = [[Gulf Oil Company]] |author2 = Rand McNally and Company |publisher = Gulf Oil Company |year = 1972 |edition = 1972 }}</ref><ref name="1980map">{{Cite FTP |author = Pennsylvania Department of Transportation |url = ftp://ftp.dot.state.pa.us/public/pdf/BPR_pdf_files/Maps/Statewide/Historic_OTMs/1980fr.pdf |title = Commonwealth of Pennsylvania Official Transportation Map |format = PDF |year = 1980 |server = Pennsylvania Department of Transportation |url-status = dead |access-date = May 8, 2010 }}</ref> This segment was built in stages during the 1980s as a [[super two]] highway.<ref name="1985map">{{cite map |author = Rand McNally and Company |publisher = Rand McNally and Company |title = New York |year = 1985 |isbn = 0-528-91040-X }}</ref><ref name="1989map">{{Cite FTP |author = Pennsylvania Department of Transportation |url = ftp://ftp.dot.state.pa.us/public/pdf/BPR_pdf_files/Maps/Statewide/Historic_OTMs/1989fr.pdf |title = Pennsylvania Official Transportation Map |format = PDF |year = 1989 |server = Pennsylvania Department of Transportation |url-status = dead |access-date = May 6, 2010 }}</ref> The portions of the freeway in and around Salamanca and Corning were completed in the late 1980s<ref name="1985map" /><ref name="1989map" /> and mid-1990s, completing the conversion of NY&nbsp;17 into a continuous expressway from the Pennsylvania state line to Harriman.<ref>{{cite map |author = Rand McNally and Company |publisher = Rand McNally and Company |title = New York |year = 1995 |isbn = 0-528-96764-9 }}</ref><ref>{{cite map |author = Rand McNally and Company |publisher = Rand McNally and Company |title = Road Atlas: United States, Canada, Mexico |year = 1999 |pages = 69, 71 |isbn = 0-528-84004-5 }}</ref>

In 1996, both exit 117 and exit 118A were closed.

The [[New York State Thruway Authority]] converted the Harriman Toll Barrier at the interchange of NY&nbsp;17 and I-87 (exit 16 on I-87) to cashless tolling. This included the creation of a solar photovoltaic energy generating facility (solar park) to help power the toll and maintenance facilities in Harriman, Woodbury, Spring Valley, and Nyack.

==Suffixed routes==
[[File:NY 17J topo.PNG|right|thumb|NY&nbsp;17 and NY&nbsp;17J marked on a 1948 topographical map]]
NY&nbsp;17 has had 13 suffixed routes bearing 11 different designations. Five are still assigned to their routes, while eight have been removed or renumbered. A fourteenth, [[NY&nbsp;17L]], was proposed in 1939 as part of current [[New York State Route 97|NY&nbsp;97]], but canceled.<ref name="NY 17L-4">{{cite news |title = Markings of New Route Denied to Avoid Confusion |newspaper = Middletown Times Herald |url = https://www.newspapers.com/clip/2994099/ny_97_17l_june_29_1939// |access-date = October 22, 2015 |agency = Middletown Times-Herald |date = June 29, 1939 |location = Middletown, NY |page = 16 |via = [[Newspapers.com]] }}</ref>

*The NY&nbsp;17A designation has been used for two distinct highways:
**The [[New York State Route 242|first NY&nbsp;17A]] was an alternate route of NY&nbsp;17 between [[Randolph (village), New York|Randolph]] and Salamanca via [[Little Valley (village), New York|Little Valley]]. It was assigned in the mid-1920s<ref name="1924nyt" /><ref name="1926map1" /> and renumbered to [[New York State Route 17H (1930–mid-1930s)|NY&nbsp;17H]] in the [[1930 state highway renumbering (New York)|1930 renumbering of state highways in New York]].<ref name="1930nyt" />
