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]].

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}}

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"/>

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"/>
