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.

I-87 was assigned on August 14, 1957, as part of the establishment of the Interstate Highway System.<ref name="1957map">{{cite map |author = [[American Association of State Highway Officials]] |url = http://commons.wikimedia/org/wiki/File:Interstate_Highway_plan_August_14,_1957.jpg |title = Official route numbering for the National System of Interstate and Defense Highways |date = August 14, 1957 |scale = Scale not given |location = Washington, DC |publisher = American Association of State Highway Officials |via = [[Wikimedia Commons]] }}{{dead link|date=March 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> The highway initially utilized the preexisting New York State Thruway from Albany to Newburgh and in lower Westchester County, and the Major Deegan Expressway in New York City. 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>

The Northway was built in segments, which became I-87 as they were completed and linked to the preexisting route.

===Filling the gaps===
The gap in the Northway between Pottersville and Keeseville was narrowed considerably by July 1967 with the completion of a {{convert|25|mi|km|adj=on}} segment from Pottersville to exit&nbsp;30 at Underwood.

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. Instead, I-87 was now proposed to begin in [[Port Chester, New York|Port Chester]] and follow a new routing through [[Purchase, New York|Purchase]], [[Armonk, New York|Armonk]], and [[Katonah, New York|Katonah]] to [[Brewster, New York|Brewster]], where it would join I-84.<ref>{{cite map |title = New York and Metropolitan New York |author1 = Sinclair Oil Corporation |year = 1962 |author2 = Rand McNally and Company |publisher = Sinclair Oil Corporation }}{{full citation needed|date=August 2015}}</ref> The routing was modified slightly by 1968: I-87 still began in New York City, then [[Concurrency (road)|overlapped]] with [[Interstate 287|I-287]] east to Purchase. From there, I-87 headed north along the now-open expressway to Armonk, where it ended at [[New York State Route 22|NY&nbsp;22]]. Another portion of the highway, from Goldens Bridge ([[New York State Route 138|NY&nbsp;138]]) to Brewster, was open as well while the part from Armonk to Katonah was under construction.<ref name="1968map">{{cite map |title = New York |author1 = Esso |year = 1968 |edition = 1969–70 |author2 = General Drafting |publisher = Esso }}{{full citation needed|date=August 2015}}</ref> This segment, as well as the part from Katonah to Goldens Bridge, was completed by 1971.<ref>{{cite map |title = New York Thruway |author1 = [[New York State Thruway Authority]] |year = 1971 |author2 = Rand McNally and Company |publisher = New York State Thruway Authority }}{{full citation needed|date=August 2015}}</ref> On January 1, 1970, I-87 was rerouted between Elmsford and Newburgh to follow the mainline of the Thruway instead, leaving the Purchase–Brewster freeway to become [[Interstate 684|I-684]].<ref>{{cite book |url = http://www.greaternyroads.info/pdfs/state70.pdf |title = Official Description of Touring Routes in New York State |date = January 1, 1970 |author = State of New York Department of Transportation |access-date = May 13, 2009 }}</ref>

===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}}). Unlike other major bridges in [[New York metropolitan area]], the Tappan Zee was designed to last only 50&nbsp;years.<ref>{{cite news |title = A Bridge That Has Nowhere Left to Go |first = Patrick |last = McGeehan |url = https://www.nytimes.com/2006/01/17/nyregion/17tappan.html |newspaper = The New York Times |date = January 17, 2006 |access-date = February 27, 2010 }}</ref> The [[Federal Highway Administration]] (FHWA) issued a report in October 2011 designating the [[Tappan Zee Bridge (2017–present)|Tappan Zee's replacement]] to be a dual-[[Span (engineering)|span]] [[twin bridges|twin bridge]].<ref name="fhwa2">{{cite web|title=Tappan Zee Hudson River Crossing Project Scoping Information Packet|url=http://www.tzbsite.com/tzbsite_2/pdf-library_2/2011-10-13%20Scoping%20Information%20Packet.pdf|access-date=October 26, 2011|author=US Federal Highway Administration|author-link=Federal Highway Administration|date=October 13, 2011|url-status=dead|archive-url=https://web.archive.org/web/20111030101223/http://www.tzbsite.com/tzbsite_2/pdf-library_2/2011-10-13%20Scoping%20Information%20Packet.pdf|archive-date=October 30, 2011}}</ref>

In 2007, a driver who crashed off the road was unable to summon help, prompting messages from local governments to telephone companies to add new wireless towers to address the problem and warning signs to inform travelers of the so-called "dark zone".<ref>{{cite news |url = http://www.wten.com/Global/story.asp?S=7746034 |title = DOT to Erect Signs on N'thway Noting Limited Cell Service |date = January 19, 2008 |publisher = [[WTEN-TV]] |location = Albany, NY |access-date = January 31, 2010 |url-status = dead |archive-url = https://web.archive.org/web/20110525184441/http://www.wten.com/Global/story.asp?S=7746034 |archive-date = May 25, 2011 |df = mdy-all }}</ref> Throughout this area, roadside emergency call boxes were located approximately every {{Convert|2|mi|km|spell=in}} on both sides of the roadway.
