Interstate 287 New Jersey / New York

East End
South End


Interstate 287 encircles the New York City metropolitan area along three distinct roads. The North Jersey portion provides both a commuter route and bypass from the New Jersey Turnpike (I-95) at Edison west to Somerville and north to Morristown, Oakland and Mahwah. This section of I-287 ties into the New York Thruway mainline (I-87) just across the New York state line at Suffern.

I-87/287 combine east along the New York Thruway to Nyack and across the Hudson River on the Governor Mario N. Cuomo Bridge. Major construction replaced the aging Tappan Zee Bridge, with the new cable-stayed bridge opened to westbound traffic on August 26, 2017, and two-way traffic on October 6, 2017. The new eastbound span opened to traffic on September 12, 2018.1

Interstate 87 and the Thruway turn south at East Irvington toward Yonkers and The Bronx, New York. Interstate 287 continues east along the often congested Cross Westchester Expressway to Rye and I-95 (New England Thruway) near the Connecticut state line.

Governor Mario M. Cuomo Bridge

The Tappan Zee Bridge operated for 62 years until 2017. The New York State Thruway Authority managed the $3.98 billion bridge project starting in 2013, when the initial foundational steel piles were driven. Anchored by eight 419-foot high towers, the cable-stayed bridge is the first built across the Hudson River. Tower construction commenced in September 2015, followed by the first road deck panel installation in November 2015. Installation of the 192 stay cables, each orientated at a five degree angle, commenced in July 2016. The final main span tower was completed in December 2016.1

A ribbon cutting ceremony took place for the Governor Mario M. Cuomo Bridge across the Hudson River on August 24, 2017. The span opened initially with four lanes of traffic carrying I-87 & 287 northbound. Work followed to ready the crossing to accommodate southbound motorists while adjacent construction continued on the companion bridge.2

The original Tappan Zee Bridge, opened in December 1955, was demolished starting first with the approaches. The replacement 3.1-mile long crossing accommodates eight general travel lanes with full shoulders and includes space for a future transit line or busway, and a bicycle/walking path.2

I-287 Annual Average Daily Traffic (AADT)

North Jersey - 1960
The Cross Westchester Expressway as I-487 – 1960 Rand McNally North American Road Atlas.

Interstate 87 was proposed separate from the New York Thruway, from the Cross Westchester Expressway north to Brewster, until 1969. An earlier alignment showed the route staying closer to the Hudson River north from Tarrytown.

I-95 north at I-287/NJ 440 - 1998
Replaced button copy signage at Exit 10 from the Outer Roadway of the NJ Turnpike north in October 1998. This guide sign, and others for I-287 and NJ 440, were replaced by Spring 2000.


The Cross Westchester Expressway opened to traffic in December 1960 at a cost of $50 million. It was initially designated as Interstate 187 in August 1958 and as Interstate 487 when it opened. It was redesignated I-287 in 1961.2

An eastern extension of Interstate 287 was proposed by Robert Moses to complete the beltway around New York via the Oyster Bay-Rye Bridge. A 6.1 mile long cabled-stayed suspension bridge across Long Island Sound was envisioned to link the east end of I-287 at Rye with an extension of NY 135 (Seaford-Oyster Bay Expressway). A study for the crossing was released by Moses in February 1966.3

Planning for the Oyster Bay-Rye Bridge halted in 1970. New studies were required following the implementation of stricter environmental legislation by the Federal government in 1970. An Environmental Impact Statement (EIS) was completed in November 1972 for a 16.5 mile roadway, including the span and approaches between I-95 and NY 25 in Syosset. New York State Mileage submitted the mileage for inclusion in the Interstate system under the Federal Highway Act of 1968.3

Residents in Rye, Oyster Bay and other locations along the proposed corridor organized to counter the bridge and extension of I-287. Their efforts and environmental concerns led to formal cancellation of the crossing by Governor Nelson Rockefeller on June 20, 1973.3

The cancellation of the Somerset Freeway in North Jersey in 1982, the proposed alignment for Interstate 95 between Lawrenceville and Metuchen, led to an extension of I-287 east from South Plainfield to the New Jersey Turnpike in Edison Township. This segment was previously designated as Interstate 95. AASHTO approved the renumbering on June 26, 1985.
