'''Interstate&nbsp;87''' ('''I-87''') is a {{convert|333.49|mi|km|adj=mid|-long}} north–south [[Interstate Highway]] located entirely within the US state of [[New York (state)|New York]]. I-87 is the main highway that connects [[New York City]] and [[Montreal]]. The highway begins at exit&nbsp;47 off [[Interstate 278|I-278]] in the New York City borough of [[the Bronx]], just north of the [[Robert F. Kennedy Bridge]]. From there, the route runs northward through the [[Hudson Valley]], the [[Capital District (New York)|Capital District]], and the easternmost part of the [[North Country (New York)|North Country]] to the [[Canada–United States border]] in the town of [[Champlain, New York|Champlain]]. At its north end, I-87 continues into [[Quebec]] as [[Quebec Autoroute 15|Autoroute&nbsp;15]] (A-15). I-87 connects with several regionally important roads: [[Interstate 95 in New York|I-95]] in New York City, [[New York State Route&nbsp;17]] (NY&nbsp;17; future [[Interstate 86 (Pennsylvania–New York)|I-86]]) near [[Harriman, New York|Harriman]], [[Interstate 84 in New York|I-84]] near [[Newburgh, New York|Newburgh]], and [[Interstate 90 in New York|I-90]] in [[Albany, New York|Albany]]. The highway is not contiguous with [[Interstate 87 (North Carolina)|I-87]] in [[North Carolina]].

I-87 was assigned in 1957 as part of the establishment of the Interstate Highway System. The portion of I-87 south of Albany follows two [[controlled-access highway]]s that predate the Interstate Highway designation, the '''Major Deegan Expressway''' (locally known as "'''the Deegan'''") in New York City and the tolled [[New York State Thruway]] from the New York City line to Albany. North of Albany, I-87 follows the '''Adirondack Northway''', a highway built in stages between 1957 and 1967 (finished just in time to bring Americans to the  [[Expo 67|World Exhibition]] held in Montreal that year). Early proposals for I-87 called for the route to take a more easterly course through the Hudson Valley and extreme southwestern [[Connecticut]] between New York City and Newburgh. These plans were scrapped in 1970 when I-87 was realigned onto the Thruway between [[Westchester County, New York|Westchester County]] and Newburgh.

==Route description==
I-87 makes up most of the major strategic corridor between [[New York City]], the largest metropolitan area in the US, and [[Montreal]], the second-largest metropolitan area in Canada (formerly the largest). The [[New York State Department of Transportation]] (NYSDOT) considers the route important for commerce, as it connects with numerous highways in the region and serves approximately 80 million people in the [[Mid-Atlantic (United States)|Mid-Atlantic states]], [[New England]], and [[Quebec]]. Motorists can connect to multiple highways to travel farther south along I-95 through the Mid-Atlantic states or farther east into New England.<ref>{{cite book |author = Parsons-Clough Harbour |date = May 2004 |chapter = 2.1: Highways and Bridges |chapter-url = https://www.dot.ny.gov/programs/i-87-multimodal-corridor-study/repository/chapter_2-1_highways_and_bridges.pdf |title = I-87 Multimodal Corridor Study |publisher = New York State Department of Transportation |page = 2.1-1 |access-date = August 14, 2015 }}</ref>

====Major Deegan Expressway====
{{Attached KML|from=Major Deegan Expressway}}
[[File:Major Deegan Expressway from 138th Street overpass jeh.jpg|left|thumb|Looking north at the Deegan from 138th Street]]
I-87 and the Major Deegan Expressway begins in [[the Bronx]] at the northern approach to the [[Robert F. Kennedy Bridge]], where it connects to the [[Bruckner Expressway]] ([[Interstate 278|I-278]]) at a [[directional T interchange]]. The route heads west from the interchange, paralleling loosely with the [[Harlem River]] through [[Mott Haven, Bronx|Mott Haven]]. After {{convert|1|mi|km|spell=in}}, the highway makes a turn to the north, mirroring a change in the nearby river's course. It passes by [[Yankee Stadium]] on its way to [[Highbridge, Bronx|Highbridge]], where the Deegan connects to the [[Cross Bronx Expressway]] ([[Interstate 95 in New York|I-95]] and [[U.S. Route 1 in New York|US Route 1]] [US 1]) at the eastern approach to the [[Alexander Hamilton Bridge]]. The Deegan remains in close proximity to the Harlem River until the waterway turns westward at [[Kingsbridge, Bronx|Kingsbridge]] to form the northern edge of [[Manhattan]].<ref name="google">{{google maps |url=https://maps.google.com/maps?saddr=Exit+47&daddr=I-87+N&hl=en&ll=40.859785,-73.926659&spn=0.187993,0.445976&sll=40.905834,-73.877617&sspn=0.002935,0.006968&geocode=FX-WbgId2x6Y-w%3BFesscAId7rWY-w&gl=us&mra=mift&mrsp=1&sz=18&t=h&z=12 |title=Overview Map of the Major Deegan Expressway |access-date=December 26, 2012}}</ref> The Major Deegan Expressway is named after [[William Francis Deegan|Major William Francis Deegan]].

[[File:Deegan 161 jeh.jpg|thumb|right|The Deegan in the [[West Bronx]]]]
[[File:Bronx Terminal Market located to the right side of I-87.jpg|thumb|right|The Deegan passing by the [[Bronx Terminal Market]]]]

North of Kingsbridge, the expressway follows a generally northeasterly alignment, passing through the center of [[Van Cortlandt Park]] as it connects to [[Mosholu Parkway]] and [[Jerome Avenue]]. Mosholu Parkway also links the Deegan to the [[Henry Hudson Parkway|Henry Hudson]] and [[Saw Mill River Parkway|Saw Mill River]] parkways, which run parallel to the Major Deegan Expressway through the western Bronx and Manhattan. Past Jerome Avenue, the freeway gains a pair of [[service road]]s and heads north to the [[New York City]] line, where it becomes the [[New York State Thruway]] as it passes into [[Westchester County, New York|Westchester County]]. The last northbound exit on the Deegan connects to McLean Avenue, located north of the city line in [[Yonkers, New York|Yonkers]]. The exit 14 ramp leads to the service road in the Bronx but does not meet McLean Avenue until it crosses the county line. Southbound access to McLean Avenue is provided by Thruway exit&nbsp;1 in Yonkers.<ref name="google" />

====New York State Thruway====
{{main|New York State Thruway}}

[[File:NewYorkStateThruway(I-87).jpg|thumb|left|Looking east along I-87/I-287 ([[NYST|the Thruway]]) toward the Tappan Zee Bridge from Nordkop Mountain in Suffern]]
At the New York City–Yonkers border, I-87's mainline continues onto the New York State Thruway and northward through Yonkers and southern [[Westchester County, New York|Westchester County]]. The first few exits serve various local streets, with exit 1 serving Hall Place, exit&nbsp;2 providing access to [[Yonkers Raceway & Empire City Casino]] and exit&nbsp;3 serving the [[Cross County Shopping Center]]. At exit&nbsp;4, I-87 connects to the [[Cross County Parkway]], an east–west [[Parkways in New York|parkway]] providing access to the Saw Mill River, [[Bronx River Parkway|Bronx River]], and [[Hutchinson River Parkway|Hutchinson River]] parkways. The north–south parkways and I-95 run parallel to the Thruway through [[Southern Westchester]]. The Bronx River parkway leaves to the northeast midway through Yonkers, while the Saw Mill and [[Sprain Brook Parkway|Sprain Brook]] parkways follow the Thruway out of the city.<ref name="Thruway Traveler Map">{{cite map |author = New York State Thruway Authority |year = 2015 |title = Traveler Map |url = http://www.thruway.ny.gov/travelers/map/index.html?layer=wta |location = Albany |publisher = New York State Thruway Authority |cartography = Google |access-date = August 3, 2015 }}</ref>

[[File:Tappan Zee Bridge 2019c.jpg|thumb|right|Tappan Zee Bridge]]
All three highways take generally parallel tracks to [[Elmsford, New York|Elmsford]], where I-87 directly intersects the Saw Mill River Parkway at exit 7A. Not far to the north is exit&nbsp;8, a [[semi-directional T interchange]] with I-287 (the Cross Westchester Expressway). I-287 joins the Thruway here, following I-87 west across the [[Hudson River]] into [[Rockland County, New York|Rockland County]] on the [[Tappan Zee Bridge (2017–present)|Tappan Zee Bridge]]. I-87 and I-287 remain [[Concurrency (road)|overlapped]] for {{convert|15|mi|km}} through the densely populated southern portion of Rockland County, meeting the [[Palisades Interstate Parkway]] and the [[Garden State Parkway Connector]], with the latter providing access to the [[Garden State Parkway]] in New Jersey. The Thruway continues generally westward to [[Suffern, New York|Suffern]], where I-87 and I-287 split at a large semi-directional T interchange (exit&nbsp;15) only about a half mile ({{Convert|0.5|mi|km|disp=output only}}) from the [[New Jersey]] border. At this point, I-287 heads south into New Jersey while I-87 and the Thruway turn northward into the valley of the [[Ramapo River]].<ref name="Thruway Traveler Map"/>

[[File:2017-09-10 10 07 10 View north along Interstate 87 (New York State Thruway) just north of Exit 15A (New York State Route 17 north, New York State Route 59, Sloatsburg, Suffern) in Ramapo, Rockland County, New York.jpg|thumb|left|View north along the Thruway in Ramapo]]
The Thruway continues north as a six-lane tollway through the river valley toward [[Harriman, New York|Harriman]], where it encounters the [[Woodbury, Orange County, New York|Woodbury]] [[open road tolling|toll gantry]], the southeastern end of the main line's major closed toll system. The barrier is located on the mainline within exit&nbsp;16 ([[New York State Route 17|NY&nbsp;17]]), a [[trumpet interchange]]. Along with the mainline barrier in Harriman, a toll gantry exists on the exit&nbsp;16 ramp midway between the Thruway and NY&nbsp;17 exit&nbsp;131 ([[New York State Route 32|NY&nbsp;32]]). Now a completely [[toll road|tolled]] highway, the Thruway heads northward as it narrows to four lanes, roughly paralleling the Hudson River to the river's west as it serves the city of [[Newburgh, New York|Newburgh]], village of [[New Paltz (village), New York|New Paltz]], and city of [[Kingston, New York|Kingston]], indirectly connecting to the short [[Interstate 587 (New York)|I-587]] in the latter.<ref name="Thruway Traveler Map"/>

Past Kingston, the highway goes closer to the river as it parallels [[U.S. Route 9W in New York|US&nbsp;9W]] through the towns of [[Saugerties, New York|Saugerties]], [[Catskill (town), New York|Catskill]], [[Coxsackie, New York|Coxsackie]], and [[Ravena, New York|Ravena]]. Just north of Ravena, the Thruway meets the west end of the Berkshire Connector, a spur linking the Thruway mainline to the [[Massachusetts Turnpike]] {{convert|25|mi|km}} to the east. The highway continues into the vicinity of [[Albany, New York|Albany]], where it connects to [[Troy, New York|Troy]] via [[Interstate 787|I-787]] at exit&nbsp;23 and intersects [[Interstate 90 in New York|I-90]] at exit&nbsp;24.<ref name="Thruway Traveler Map"/> The latter of the two junctions is the busiest of the Thruway's exits, serving an estimated 27&nbsp;million vehicles a year.<ref>{{cite news |title = At a transportation crossroad |newspaper = [[Times Union (Albany)|Times Union]] |location = Albany, NY |date = October 26, 2007 |access-date = April 17, 2010 |page = 56 |url = http://alb.merlinone.net/mweb/wmsql.wm.request?oneimage&imageid=6428652 |archive-date = July 23, 2011 |archive-url = https://web.archive.org/web/20110723205754/http://alb.merlinone.net/mweb/wmsql.wm.request?oneimage&imageid=6428652 |url-status = dead }}</ref> I-87 then widens to six lanes and runs across the capital city's residential suburbs for {{convert|6|mi|km|spell=in}} to exit&nbsp;24, a complex interchange with I-90. At this point, I-87 leaves the Thruway to access the nearby south end of the toll-free Adirondack Northway, also known simply as the Northway, while I-90 merges in from the east to follow the Thruway toward [[Buffalo, New York|Buffalo]] and then [[Pennsylvania]].<ref name="google" /><ref name="Thruway Traveler Map"/>

===Adirondack Northway===
Off the Thruway, I-87 and I-90 overlap for a half mile ({{Convert|0.5|mi|km|disp=output only}}) along I-90's toll-free path through the Albany area. The brief concurrency ends at exit&nbsp;1 of the Adirondack Northway in [[Guilderland, New York|Guilderland]], a junction also numbered as exit&nbsp;1 on I-90. The Adirondack Northway and I-87 are still separate routes that share the same path; the Northway itself actually begins not at I-87/I-90 but about {{convert|1|mi|km|spell=in}} south from its interchange, the Northway reaches its southern terminus at Western Ave ([[U.S. Route 20 in New York|US&nbsp;20]]), and then joins with I-87 for the rest of its route. I-87 turns to head north toward the Canada–United States border at [[Champlain, New York|Champlain]] while I-90 continues east toward downtown Albany and [[Rensselaer County, New York|Rensselaer County]].<ref name="google" /> South of this point, the Northway feeds into a {{convert|0.86|mi|km|adj=on}} expressway spur known locally as [[Streets of Albany, New York#Northway/Fuller Road Alternate|Fuller Road Alternate]],<ref name="2011tvr">{{cite web |url = https://www.dot.ny.gov/divisions/engineering/technical-services/hds-respository/Traffic%20Volume%20Report%202011.pdf |access-date = December 26, 2012 |title = 2011 Traffic Volume Report for New York State |date = September 25, 2012 |pages = 142–145, 207, 242, 244–245, 261, 263 |publisher = [[New York State Department of Transportation]] }}</ref> which links I-87 and I-90 to US&nbsp;20.<ref name="google" /> Fuller Road Alternate is designated as '''New York State Route 910F''' ('''NY&nbsp;910F'''), an unsigned [[List of reference routes in New York|reference route]], by [[New York State Department of Transportation|NYSDOT]].<ref name="2011tvr" /> In 2004, NYSDOT ceremonially designated the entire {{convert|176|mi|km|adj=on}} Northway as the Adirondack Veterans Memorial Highway.<ref>{{cite news |title = Northway renamed for veterans |newspaper = [[The Daily Gazette]] |date = November 6, 2004 |location = Schenectady, NY |page = B6 }}</ref>

The Northway, the part of Interstate 87 (I-87) north of the New York State Thruway, was built in segments, which became I-87 as they were completed and linked to the pre-existing route. Construction began in the late 1950s on the portion of the Northway between the Thruway and [[New York State Route 7|NY&nbsp;7]] near [[Latham, New York|Latham]], and it was completed in 1960.<ref>{{cite map |title=New York with Special Maps of Putnam–Rockland–Westchester Counties and Finger Lakes Region |publisher=[[Esso]] |cartography=[[General Drafting]] |edition=1955–56 |year=1954}}</ref> 

====Albany and Saratoga counties====
I-87 heads northeast from I-90 as a six-lane freeway with three lanes in each direction. It immediately traverses the [[Albany Pine Bush]] Preserve and passes west of [[Rensselaer Lake]] before crossing [[CSX Transportation]]'s [[Hudson Subdivision]] and running parallel to Wolf Road, a business thoroughfare through the town of [[Colonie, New York|Colonie]]. Wolf Road itself begins adjacent to exit&nbsp;2, a [[cloverleaf interchange]] with [[New York State Route 5|NY&nbsp;5]] (Central Avenue). Heading northbound, the ramp for exit&nbsp;2E feeds directly into the intersection of NY&nbsp;5 and Wolf Road, located just west of [[Colonie Center]], one of the [[Capital District (New York)|Capital District]]'s largest enclosed shopping malls. I-87 continues to run alongside Wolf Road to exit&nbsp;4, a modified [[diamond interchange]] serving [[County Route 151 (Albany County, New York)|County Route&nbsp;151]] (CR&nbsp;151, named Albany Shaker Road) and [[Albany International Airport]]. Wolf Road ends south of the exit; however, another section begins north of the junction, carrying [[New York State Route 155|NY&nbsp;155]] away from the airport. Prior to the Northway, there was no break in Wolf Road; in essence, exit&nbsp;4 was built on top of Wolf Road's intersection with Albany Shaker Road. I-87 and NY&nbsp;155 meet at exit&nbsp;5, with the latter routed along Watervliet Shaker Road.<ref name="google" />

[[File:Thaddeus Kosciusko Bridge Albany Summer.jpg|thumb|left|The [[Thaddeus Kosciusko Bridge]] carries I-87 (the Northway) over the [[Mohawk River]] north of [[Albany, New York|Albany]].]]
After a brief stretch of housing tracts, I-87 connects to [[New York State Route 2|NY 2]] and [[New York State Route 7|NY&nbsp;7]] at exit&nbsp;6, a [[single-point urban interchange]], in a commercialized part of [[Latham, New York|Latham]]. NY&nbsp;7 joins I-87 here, following the freeway for roughly {{convert|0.8|mi|km}} to exit&nbsp;7, the west end of a limited-access highway previously known locally as Alternate Route&nbsp;7. While NY&nbsp;7 heads east toward [[Troy, New York|Troy]], I-87 continues north past gradually less commercialized areas as it approaches the northern county line. The businesses ultimately give way to stretches of homes and subdivisions as the highway crosses into [[Saratoga County, New York|Saratoga County]] by way of the [[Thaddeus Kosciusko Bridge]], called by locals "the [[twin bridges]]", spanning the [[Mohawk River]].<ref name="google" /> The northern portion of the Northway through Colonie and Saratoga County is now a heavily traveled commuter route as a six-lane freeway. Since the highway's construction, Saratoga County has become the fastest growing area of the Capital District, and indeed all of upstate New York.<ref>{{cite news |title = Growing predicament |last = Aaron |first = Kenneth |date = October 3, 2004 |newspaper = [[Times Union (Albany)|Times Union]] |location = Albany, NY }}</ref>

For its first few miles in Saratoga County, I-87 runs across lightly developed parts of the towns of [[Halfmoon, New York|Halfmoon]] and [[Clifton Park, New York|Clifton Park]]. Near exit&nbsp;9, however, the freeway passes through the commercial center of Clifton Park as it connects to [[New York State Route 146|NY&nbsp;146]]. [[Clifton Park Center]], one of several shopping plazas at the junction, is situated southwest of the exit. Past exit&nbsp;9, the commercial development subsides as I-87 traverses another area dominated by housing tracts. Just north of the exit, the freeway passes a rest area for northbound traffic. The freeway continues on, passing to the west of the centers of [[Round Lake (village), New York|Round Lake]] at exit&nbsp;11 and [[Malta, New York|Malta]] at exit&nbsp;12. The roadway then meets [[U.S. Route 9 in New York|US&nbsp;9]] at Exit 13, a [[cloverleaf interchange]] providing access to [[Saratoga Spa State Park]] and downtown Saratoga Springs.  I-87 turns slightly to the northeast and begins to loosely parallel the northwestern edge of [[Saratoga Lake]] as it crosses [[Kayaderosseras Creek]] and enters [[Saratoga Springs, New York|Saratoga Springs]].<ref name="google" />

As the route travels the east side of Saratoga Springs, it meets [[New York State Route 9P|NY&nbsp;9P]] at exit&nbsp;14. The junction is adjacent to the regionally popular [[Saratoga Race Course]] and thus receives heavy traffic during the racing season. A southbound-only entrance ramp exists off Nelson Avenue Extension about {{convert|1|mi|km|spell=on}} south of exit&nbsp;14, designed to handle traffic exiting the track at [[Saratoga Race Course]] and the [[Saratoga Casino Hotel]]. The highway continues around the eastern edge of Saratoga Springs to exit&nbsp;15, where the relatively undeveloped areas east of I-87 are briefly replaced by [[Wilton, New York|Wilton]]'s commercial district along [[New York State Route 50|NY&nbsp;50]]. As I-87 continues northeast through Wilton, it heads across significantly less developed areas, with open fields becoming the most common feature along the road. It continues into [[Moreau, New York|Moreau]], connecting to [[U.S. Route 9 in New York|US&nbsp;9]] and serving [[Moreau Lake State Park]] by way of exit&nbsp;17, a once [[cloverleaf interchange]] being converted to a "Parclo A2" [[Partial cloverleaf interchange]], before crossing the Hudson River and entering [[Warren County, New York|Warren County]].<ref name="google" />

====Warren and Essex counties====
[[File:View north along I-87, Adirondack Northway, in Warren County, NY.jpg|thumb|Northbound Northway in Warren County between exits&nbsp;23 and 24|alt=A view of a divided highway from its righthand roadway, with two lanes separated by a dashed white line. There is almost no other traffic; the surrounding area is wooded with some autumn color visible. Ahead the roadways curves by a hill and disappears.]]
Between the bridge and exit&nbsp;18, I-87 passes two rest areas, one for each direction. The road's northward course quickly brings it to the outskirts of [[Glens Falls, New York|Glens Falls]], and as such the highway heads across another swath of residential neighborhoods. Exits&nbsp;18 and&nbsp;19 are the main exits for the city, with the latter connecting to [[New York State Route 254|NY&nbsp;254]] near [[Aviation Mall]], located on NY&nbsp;254 just west of the route's junction with US&nbsp;9. A northwestern turn in the freeway takes I-87 past the [[Great Escape (amusement park)|Great Escape]] amusement park and [[Six Flags Great Escape Lodge & Indoor Waterpark|lodge]], both of which are accessed from exit&nbsp;20 and [[New York State Route 149|NY&nbsp;149]]. Past exit&nbsp;20, I-87 runs across increasingly remote areas of Queensbury as the road enters [[Adirondack Park]] and heads toward [[Lake George (town), New York|Lake George]]. The freeway closely follows US&nbsp;9 northwest to the village of [[Lake George (village), New York|Lake George]], where I-87 meets [[New York State Route 9N|NY&nbsp;9N]] via exits&nbsp;21 and&nbsp;22. Route&nbsp;9N veers to the northeast along the shore of Lake George as "Lake Shore Drive", toward the town of [[Bolton Landing, New York|Bolton Landing]], a popular village on the shore of Lake George with shops and restaurants. Exit&nbsp;22 is the last exit before the Northway begins traversing approximately {{convert|90|mi|km}} of mostly rural areas where the exits become farther apart. Here, the Northway narrows from six to four lanes, preparing for the more rural areas and rugged terrain that follow.<ref name="google" />
[[File:View N along I-87 to Adirondack High Peaks region.jpg|thumb|left|View to [[Adirondack High Peaks|High Peaks]] region from the northbound side of the Northway in [[Schroon Lake (hamlet), New York|Schroon Lake]]|alt=A two-lane roadway with a white dashed line in the center, white solid line at the right edge, dashed yellow line at the left and brown metal guardrail alongside the left edge, with woods on either side, drops down a slope in the foreground. In the distance, blue with haze, is an irregular, ragged ridgeline]]
North of Lake George, the Northway runs alongside US&nbsp;9 to [[Warrensburg, New York|Warrensburg]], a small town on the [[Schroon River]] served by exit&nbsp;23. The view straight ahead on the northbound side from this interchange acts as an unofficial gateway to the Adirondacks, with tall mountains acting as a backdrop to a straight stretch of highway. While US&nbsp;9 heads northwest into the [[Warrensburg, New York|Warrensburg]] to connect to [[New York State Route 28|NY&nbsp;28]], I-87 turns northward to follow the east bank of the Schroon River for {{convert|17|mi|km}} through a deep, remote valley. The Northway reaches exit&nbsp;24 while in this valley, which once again serves the town of [[Bolton Landing, New York|Bolton Landing]]. Exit&nbsp;25 serves [[New York State Route 8|NY&nbsp;8]] at a [[diamond interchange]]. The stretch away from US&nbsp;9 ends at exit&nbsp;26, where I-87 reconnects to US&nbsp;9 in [[Pottersville, New York|Pottersville]]. At this point, I-87 makes a slight turn to the northeast to follow US&nbsp;9 as the latter road runs along the western shoreline of Schroon Lake. Both roads pass a handful of lakefront properties on their way into [[Essex County, New York|Essex County]] and the town of [[Schroon Lake (hamlet), New York|Schroon Lake]], where the lake comes to an end and [[New York State Route 74|NY&nbsp;74]] begins its eastward trek to [[Ticonderoga, New York|Ticonderoga]] at exit&nbsp;28. The Schroon River resumes north of the exit, and I-87 and US&nbsp;9 follow the river and its rural valley to the northeast for {{convert|15|mi|km}} to the town of [[North Hudson, New York|North Hudson]].<ref name="google" />

In North Hudson, the valley becomes less pronounced as the Schroon River reaches its [[river source|source]] near exit&nbsp;30. Here, US&nbsp;9 and I-87 cross paths again, with the former heading northwest toward [[Keene, New York|Keene]] and the latter continuing northeast in a narrow valley formed by Ash Craft Brook. After {{convert|5|mi|km|spell=in}}, the stream reaches its source at Lincoln Pond, leaving the Northway to climb in elevation and wind its way northeastward across the surrounding mountains. It reaches slightly more level ground in [[Westport, New York|Westport]], where I-87 connects to NY&nbsp;9N at exit&nbsp;31. From here, the highway takes a generally northerly track across the [[Boquet River]] to the town of [[Lewis, Essex County, New York|Lewis]], rejoining US&nbsp;9 as both roads head toward [[Clinton County, New York|Clinton County]]. They split again after {{convert|7|mi|km|spell=in}} as US&nbsp;9 veers more easterly than I-87 to serve [[Keeseville, New York|Keeseville]]. The Northway, meanwhile, heads to the northwest, bypassing the village to cross the [[Ausable River (New York)|Ausable River]] and enter Clinton County.<ref name="google" />

====Clinton County====
Just across the county line, I-87 intersects NY&nbsp;9N again at exit&nbsp;34 in [[Keeseville, New York|Keeseville]], finally leaving the more rural, mountainous areas of the [[Adirondack Mountains]] and entering a more populated region. Exit&nbsp;34 is the southernmost junction to feature [[bilingual]] guide signs in [[English language|English]] and [[French language|French]] due to the road's proximity to [[Quebec]]. Beyond NY&nbsp;9N, the Northway curves to the north, running along the west side of Keeseville before entering another rural but fairly level stretch that follows I-87 out of Adirondack Park. Now outside the park, the highway encounters more frequent pockets of development as it follows [[New York State Route 22|NY&nbsp;22]] into the town of [[Plattsburgh (town), New York|Plattsburgh]]. Just inside the town line, the Northway crosses over the Salmon River and intersects NY&nbsp;22 at exit&nbsp;36, a junction serving nearby [[Plattsburgh International Airport]]. While NY&nbsp;22 heads northeast into the city of [[Plattsburgh, New York|Plattsburgh]], I-87 runs north through its western suburbs, passing over the [[Saranac River]] and intersecting [[New York State Route 3|NY&nbsp;3]] at exit 37. The Northway and NY&nbsp;22 meet again north of downtown at exit&nbsp;38.<ref name="google" />

[[File:Northway Exit 34 (NY 915F).jpg|thumb|right|Bilingual sign for exit&nbsp;34 (NY&nbsp;9N) in [[Keeseville, New York|Keeseville]]]]
The section of I-87 between exits&nbsp;38 and&nbsp;39 crosses a marshy area surrounding Dead Creek, a stream feeding into nearby [[Plattsburgh Bay]]. Access to the bay shore is provided off to the northeast by exit&nbsp;39, a modified cloverleaf interchange for [[New York State Route 314|NY&nbsp;314]]. Continuing away from the junction, I-87 comes within {{convert|1|mi|km|spell=in}} of [[Lake Champlain]] as it follows US&nbsp;9 away from Plattsburgh and northward across open, rolling fields in the towns of [[Beekmantown, New York|Beekmantown]] and [[Chazy, New York|Chazy]]. Outside of the hamlet of Chazy, the Northway begins to run across a series of [[wetland]]s along the west side of US&nbsp;9. The marshy terrain follows I-87 into the town of Champlain, where I-87 encounters the northernmost community along its course, the village of [[Champlain (village), New York|Champlain]]. I-87 veers slightly westward to avoid the village, and in doing so it meets [[U.S. Route 11 in New York|US&nbsp;11]] at exit&nbsp;42, a diamond interchange just west of the village limits.<ref name="google" />

I-87 takes a northerly track from US&nbsp;11, crossing the [[Chazy River]] and briefly entering the village limits, where it runs past a series of homes and businesses built up along nearby US&nbsp;9. As both roads head north out of the village, US&nbsp;9 connects to the Northway one last time (also the northern terminus of US&nbsp;9) at exit&nbsp;43, the last interchange on I-87 before the Canada–United States border. Past the exit, the highway doubles in width, becoming eight lanes wide as it begins to run past the customs facilities on the American side of the border. The Northway and I-87 end shortly thereafter at the Canada–United States border, where the highway continues past the [[Champlain–St. Bernard de Lacolle Border Crossing]] into Quebec as [[Quebec Autoroute 15|A-15]] toward Montreal.<ref name="google" />

[[File:Major Deegan Expy BGS.jpg|thumb|right|Overhead signage at the northern terminus of the Major Deegan Expressway]]
The origins of the Major Deegan Expressway date back to 1936 when the [[Regional Plan Association]] concluded that in order to relieve [[New York City]]'s traffic problems, a limited-access, truck-accessible expressway should be built on the west side of [[the Bronx]]. This route would connect the brand-new [[Robert F. Kennedy Bridge|Triborough Bridge]] to the proposed [[New York State Thruway]] in [[Westchester County, New York|Westchester County]]. A {{convert|1.5|mi|km|adj=on}} section of the expressway from the bridge to the [[Grand Concourse (Bronx)|Grand Concourse]] was completed in April 1939. The highway was adorned with Whitestone-style light posts placed every {{convert|75|ft|m}} of the six-lane highway, each of which were {{convert|12|ft|m}} in width.<ref name="nyc">{{cite web |url=http://www.nycroads.com/roads/major-deegan/ |first=Steve |last=Anderson |title=Major Deegan Expressway (I-87) |work=NYCRoads |access-date=November 17, 2009}}</ref> The expressway was designated as '''New York State Route&nbsp;1B''' ('''NY&nbsp;1B''') {{circa|1941}};<ref>{{cite map |title=New York Info-Map |publisher=[[Gulf Oil Company]] |year=1940 |cartography=[[Rand McNally and Company]]}}</ref><ref>{{cite map |publisher=[[H.M.

From Newburgh to the Elmsford area, I-87 was to follow [[Hudson River Expressway|a new highway]] running parallel to US&nbsp;9 northward along the eastern bank of the [[Hudson River]] to [[Fishkill, New York|Fishkill]]. I-87 would then have followed the proposed I-84 across the Hudson to rejoin the Thruway outside of Newburgh. After the Hudson River Expressway proposal was cancelled in the 1960s, the alignment of I-87 was shifted farther east to follow a newly completed freeway in the Route 22 corridor that started at I-287 in White Plains, then cut north through the extreme southwest corner of [[Connecticut]] before reentering New York and reaching I-84 at Brewster. I-87 then followed I-84 west to Newburgh. In 1970, the I-87 designation was shifted to the New York State Thruway between Newburgh and the Deegan Expressway; its previous alignment between Brewster and White Plains was redesignated as [[Interstate 684|I-684]]. Meanwhile, all of the Adirondack Northway, the portion of I-87 slated to extend from Albany north to the Canada–United States border, had yet to be built.<ref name="1958map">{{cite map |title = New York with Special Maps of Putnam–Rockland–Westchester Counties and Finger Lakes Region |author1 = [[Esso]] |author2 = [[General Drafting]] |edition = 1958 |year = 1958 |publisher = Esso }}{{full citation needed|date=August 2015}}</ref><ref name="1960map">{{cite map |title = New York and New Jersey Tourgide<!--sic--> Map |author1 = [[Gulf Oil Company]] |author2 = [[Rand McNally and Company]] |year = 1960 |publisher = Gulf Oil Company }}{{full citation needed|date=August 2015}}</ref> Fuller Road Alternate, the spur leading south from the Adirondack Northway to [[U.S. Route 20 in New York|US&nbsp;20]], was originally intended to be part of the Southern Albany Expressway, a proposed highway which would have connected the Northway with [[Interstate 787|I-787]] and run parallel to the Thruway between exits&nbsp;23 and&nbsp;24.<ref name="Southern Albany Expressway">{{cite news |last = Johnson |first = Carl |date = March 8, 2011 |title = The Highway that Was Almost Buried Under Washington Park |url = http://alloveralbany.com/archive/2011/03/08/the-highway-that-was-almost-buried-under-washingto |work = All Over Albany |archive-url = https://web.archive.org/web/20150923085939/http://alloveralbany.com/archive/2011/03/08/the-highway-that-was-almost-buried-under-washingto |archive-date = September 23, 2015 |url-status = live |df = mdy-all }}</ref>

Another gap in I-87 existed in downstate New York, as the plan to build I-87 along the proposed Hudson River Expressway had been scrapped by 1962.

===Tappan Zee Bridge replacement===
{{Main|Tappan Zee Bridge (2017–present)}}
[[File:Tappan Zee Bridge - Hudson River.JPG|thumb|Original Tappan Zee Bridge]] The original [[Tappan Zee Bridge (1955–2017)|Tappan Zee Bridge]], carrying the concurrency of [[New York State Thruway]], I-87, and [[Interstate 287|I-287]], was a [[cantilever bridge]] built during 1952–55. The bridge was {{convert|3|mi|km|spell=in}} long and spanned the Hudson at its second-widest point. Before its replacement in 2017, the deteriorating structure carried an average of 138,000&nbsp;vehicles per day, substantially more traffic than its designed capacity. During its first decade, the bridge carried fewer than 40,000&nbsp;vehicles per day. Part of the justification for replacing the bridge stems from its construction immediately following the [[Korean War]] on a low budget of only $81&nbsp;million (equivalent to ${{Formatprice|{{inflation|US-GDP|81000000|1955}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}}).

A long stretch of the Northway through the [[Adirondack Park]] had been an unserved zone for [[cellular telephone]] service.
