'''Interstate&nbsp;287''' ('''I-287''') is an [[auxiliary Interstate Highway]] in the US states of [[New Jersey]] and [[New York (state)|New York]]. It is a partial [[beltway]] around [[New York City]], serving northern New Jersey and the counties of [[Rockland County, New York|Rockland]] and [[Westchester County, New York|Westchester]] in New York. I-287, which is signed north–south in New Jersey and east–west in New York, follows a roughly horseshoe-shaped route from the [[New Jersey Turnpike]] ([[Interstate 95 in New Jersey|I-95]]) in [[Edison, New Jersey]], clockwise to the [[New England Thruway]] ([[Interstate 95 in New York|I-95]]) in [[Rye, New York]], for {{convert|98.72|mi|km|2}}. Through New Jersey, I-287 runs west from its southern terminus in Edison through suburban areas. In [[Bridgewater Township, New Jersey|Bridgewater Township]], the freeway takes a more northeasterly course, paralleled by [[U.S. Route 202 in New Jersey|US Route&nbsp;202]] (US&nbsp;202). The northernmost part of I-287 in New Jersey passes through mountainous surroundings. Upon entering New York at [[Suffern, New York|Suffern]], I-287 turns east on the [[New York State Thruway]] ([[Interstate 87 (New York)|I-87]]) and runs through Rockland County. After crossing the [[Hudson River]] on the [[Tappan Zee Bridge (2017–present)|Tappan Zee Bridge]], I-287 splits from I-87 near [[Tarrytown, New York|Tarrytown]] and continues east through Westchester County on the '''Cross Westchester Expressway''' until it reaches the New England Thruway. Within New Jersey, I-287 is maintained by the [[New Jersey Department of Transportation]] (NJDOT), and, within New York, it is maintained by the [[New York State Thruway Authority]] (NYSTA).

A bypass around New York City had been planned since the 1950s and would become a part of the Interstate Highway System and receive the I-287 designation. The Cross Westchester Expressway, which was originally designated as '''Interstate&nbsp;187''' ('''I-187'''), opened in 1960 as '''Interstate&nbsp;487''' ('''I-487''') before becoming part of I-287 a year later. The New York State Thruway portion of I-287, which included a crossing of the Hudson River, opened in 1955. In New Jersey, the proposed I-287 had originally been designated as FAI Corridor&nbsp;104 and incorporated what was planned as the '''Middlesex Freeway'''. The New Jersey section of I-287 between the New Jersey Turnpike in Edison and US&nbsp;202 in [[Montville, New Jersey|Montville]] opened in stages between the 1960s and 1973; the remainder was completed by 1994. The aging [[Tappan Zee Bridge (1955–2017)|Tappan Zee Bridge]] was replaced with a [[Tappan Zee Bridge (2017–present)|new span]] which opened in stages between 2017 and 2018.

A [[Long Island Sound link|proposed tunnel]] across the [[Long Island Sound]] between Rye and [[Oyster Bay (hamlet), New York|Oyster Bay]] on [[Long Island]] would link the eastern terminus of I-287 to [[New York State Route 25]] (NY&nbsp;25) and [[New York State Route 135|NY&nbsp;135]] in [[Syosset, New York|Syosset]].

Plans for a limited-access road to cross Westchester County east to west date back to the 1920s and became more needed after post-[[World War II]] traffic increases. When the Tappan Zee Bridge was proposed around 1950, the Cross Westchester Expressway was becoming a more realistic idea.<ref name=westchester/> Construction of the freeway began in 1956, and was given the NY&nbsp;119 designation. The design of the highway met [[Interstate Highway standards]] after opening and was supposed to have the I-187 designation. However, by the time the highway opened in 1960, it was officially designated as I-487 instead. At a cost of $50&nbsp;million (equivalent to ${{Formatprice|{{inflation|US-GDP|50000000|1960}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}}), the Cross Westchester Expressway was opened December 1960.<ref name=nyt18>{{cite news |title=Westchester Expressway Link Opens Soon, Ahead of Schedule |newspaper=The New York Times |date=December 2, 1960}}</ref> 

In 1961, this segment of road was redesignated I-287 to make it a part of the beltway around New York City.<ref name="esso"/> I-287 was to continue past I-95 in Port Chester and was to cross [[Long Island Sound]] via the unbuilt [[Long Island Crossing|Oyster Bay–Rye Bridge]].<ref name="nassau/suffolk66plan">{{cite book|author=Moses, Robert|title=Proposed Bayville&ndash;Rye Bridge|publisher=Nassau&ndash;Suffolk Regional Planning Board |year=1966}}</ref><ref name="eis">{{cite journal|last=Moses|first=Robert|author2=Federal Highway Administration, Metropolitan Transportation Authority and New York State Department of Transportation|date=November 1972|title=Oyster Bay–Rye Bridge, Administrative Action Final Environmental Impact Statement and Section 4(f) Statement|publisher=[[Federal Highway Administration]], [[Metropolitan Transportation Authority]], and New York State Department of Transportation}}</ref> On [[Long Island]], the route would run along the [[Seaford–Oyster Bay Expressway]] ([[New York State Route 135|NY&nbsp;135]]).

The plans for the bridge, and the I-287 extension onto Long Island, were dropped in 1973 by Governor [[Nelson Rockefeller]] as a result of community opposition and environmental concerns.<ref name=nyt19>{{cite news |title=Governor To Cease Efforts To Build LI Sound Bridge |newspaper=The New York Times |date=June 21, 1973}}</ref>

The [[Tappan Zee Bridge (1955–2017)|Tappan Zee Bridge]], carrying the concurrency of [[New York State Thruway]], I-87, and I-287, was a [[cantilever bridge]] built during 1952–1955. 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 the [[New York metropolitan area]], the Tappan Zee was designed to last only 50&nbsp;years.<ref>{{cite news|url=https://www.nytimes.com/2006/01/17/nyregion/17tappan.html|title=A Bridge That Has Nowhere Left to Go|last=McGeehan|first=Patrick|date=January 17, 2006|newspaper=The New York Times|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 dual-[[span (architecture)|span]] [[twin bridges]].<ref name="fhwa2">{{cite web|url=http://www.tzbsite.com/tzbsite_2/pdf-library_2/2011-10-13%20Scoping%20Information%20Packet.pdf|title=Tappan Zee Hudson River Crossing Project Scoping Information Packet|author=US Federal Highway Administration|author-link=Federal Highway Administration|date=October 13, 2011|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|url-status=dead|access-date=October 26, 2011|df=mdy-all}}</ref> Construction officially began in October 2013,<ref>{{Cite news|url=https://www.governor.ny.gov/news/governor-cuomo-announces-beginning-formal-construction-new-ny-bridge-replace-tappan-zee|title=Governor Cuomo Announces Beginning of Formal Construction of the New NY Bridge to Replace Tappan Zee|date=September 28, 2014|access-date=2017-08-29|publisher=Office of Governor Andrew M.

==Memorial designations==
{{unreferenced|section|date=January 2025}}
I-287 has been designated as the Korean War Veterans Memorial Highway since 1995. There are signs on the highway and sections are named in honor of Korean War veterans. The Morris County portion is designated for U.S. Marine Corps veteran Hector Cafferata Jr., a Medal of Honor recipient. The Bergen County portion is designated for U.S. Army Staff Sergeant Walter Bray, and the Passaic County portion for Air Force gunner Clarence "Red" Mosely. The Somerset County portion is dedicatetd to Navy Captain Joseph Azzolina, and the Middlesex County portion for Lt. Col. Richard Lauer. The I-287/Harter Road interchange at exit 33 in Morris Township is named the Warren E. Wilhide Interchange in honor of a U.S. Army veteran who was based in Chunchon, Korea, and lived very close to the Harter Road exit.
