Interstate 87 (abbreviated I-87) is a long intrastate Interstate Highway located entirely within New Yorkmarker, United Statesmarker. It is the longest intrastate Interstate Highway in the Interstate Highway System. Its southern end is at the The Bronxmarker approach to the Robert F.marker Kennedy Bridgemarker in New York Citymarker. The northern end is at the Canada – United States border in Champlainmarker, where it continues into Quebecmarker as Autoroute 15. I-87 interchanges with New York State Route 17 (future Interstate 86) near Harrimanmarker, Interstate 84 near Newburghmarker, and Interstate 90 in Albanymarker. The portion of I-87 between the New York Citymarker line and Albany is part of the New York State Thruway. North of Albany, I-87 is named the Adirondack Northway.

Route description

Major Deegan Expressway

Interstate 87 begins at an intersection with the Bruckner Expressway (I-278) at the Robert F.marker Kennedy Bridgemarker. For the next , Interstate 87 is known as the Major William Francis Deegan Expressway, which travels through the Bronx. The first exit along the Major Deegan northbound is for Willis Avenue and the nearby Third Avenue Bridgemarker. There is an exit before this going southbound, for Brook Avenue. At , Grand Concourse interchanges at Exit 3. East 149th Street is the next exit, which heads into the heart of the Bronx. Exit 5, which is signed for East 161st Street, actually lets off at Jerome Avenue, near Yankee Stadiummarker. Exit 6 is only accessible via Exit 5 (going northbound) and is for East 153rd Street. Exit 7 is for the Cross Bronx Expressway and Trans-Manhattan Expresswaymarker, both of which are signed as I-95 and US 1. Exit 8 is for West 179th Street, which becomes Burnside Avenue soon after. Exit 9 parallels the Major Deegan for ending at West Fordham Road.

Signage for the Major Deegan Expressway
U.S. Route 9 now parallels the Major Deegan, which is accessible via Exit 10 for West 230th Street. Interstate 87 then enters Van Cortlandt Parkmarker and interchanges with Van Cortlandt Park South at Exit 11. Exit 12 is for the Henry Hudson Parkway and Saw Mill River Parkway, both of which are accessible by the Mosholu Parkway. Exit 13 is for East 233rd Street and Jerome Avenue. Exit 14 is at the northern end of Van Cortlandt Park, is for McLean Ave. The Major Deegan Expressway crosses into Westchester Countymarker at Yonkersmarker and becomes the New York State Thruway, a , state-wide toll highway.

New York State Thruway

The section of highway between the New York Citymarker line and the junction with Interstate 90 at Albanymarker is part of the New York State Thruway. Interstate 87 enters Westchester at Yonkersmarker. The first exit going northbound is for Hall Place, while going southbound it is for McLean Avenue. (McLean Avenue is Exit 14 going northbound on the Major Deegan. There is no southbound Exit 14.) Yonkers Avenue interchanges at . Present just off Exit 2 is Yonkers Racewaymarker. Exit 3 is for Miles Square Road, which interchanges just after the Cross County Shopping Center. Exit 4 is for the Cross County Parkway, which interchanges just after the shopping center. Exit 5 follows a frontage road, which heads for New York State Route 100 and the Sprain Brook Parkway. Soon after, Tuckahoe Road interchanges just before leaving Yonkers. Exit 6A is for Stew Leonard Drive, which is just a road for Sprain Ridge Park.

As Interstate 87 heads northward, New York State Route 9A begins to parallel, interchanging at Exit 7. The Saw Mill River Parkway is also parallel, intersecting at Exit 7A. Before Exit 8, the Ardsley Service Area is accessible northbound. Exit 8 is for Interstate 287, beginning a concurrency for the next . The exit is also the access for the Cross-Westchester Expresswaymarker. Exit 9 is the final exit before the Tappan Zee Bridgemarker. The exit is for New York State Route 119 and the nearby U.S. Route 9. All trucks with Class A and Class B explosives must leave at Exit 9. Interstates 287 and 87 cross the Tappan Zee and enter Rockland Countymarker.

Interstate 87 begins a stretch in Rockland County. Exit 10 is the first exit after the Tappan Zee and is for U.S. Route 9W in Nyackmarker. Exit 11 is in downtown Nyack, for Route 9W going northbound and New York State Route 59 going southbound. 87 then passes the Mountainview Nature County Park as it reaches Exit 12, which is located in the outskirts of Nyack. Exit 12 is a folded-diamond interchange for New York State Route 303 and Palisades Center Mall. The first highway in interchanges at Exit 13, the Palisades Interstate Parkway.

Exit 21 sign in Cairo
The road has three current spur routes: I-287 connects with its parent in a 19-mile (31 km) long concurrency near the southern end of the highway, with I-87 signed as south/north, and I-287 signed as east/west. It is a partial beltway around New York City. West of the concurrency at exit 15, it loops around New York to meet the New Jersey Turnpike in Middlesex County, New Jerseymarker. East of the concurrency, I-287 continues as the Cross Westchester Expresswaymarker to end at I-95 (the New England Thruway) in Rye, New Yorkmarker, near the Connecticutmarker border. Note that I-287 leaves New York state, while its parent does not, making I-287 one of only a few three-digit interstates that goes through more states than its parent. Moving north, I-587 is less than 2 miles (3.2 km) long. It is unusual in that it has no interchanges along its length: its eastern terminus is at a signalized intersection, while its western terminus is at a roundabout (where it connects to Interstate 87). Because there is no direct exit from I-87 into Albanymarker, the 15 km long Interstate 787 serves traffic from the Thruway into the city.

Adirondack Northway

North of Albanymarker, Interstate 87 is known as the Adirondack Northway (or simply the Northway) and continues all the way to the Canada – United States border at Champlain. I-87 joins the Northway at exit 1; however, the Northway begins south of the I-87 / I-90 interchange at U.S. Route 20 in Guilderlandmarker. This short expressway spur, known locally as Fuller Road Alternate, and the Crossgates Mall Freeway (because it is near the Crossgates Mallmarker and also directs an exit to the mall via Crossgates Mall Road) is designated as NY 910F, an unsigned reference route, by the New York State Department of Transportationmarker.

Between exits 2 and 4, I-87 closely parallels Wolf Road, a business thoroughfare through the town of Coloniemarker. Wolf Road forks from I-87 at the cloverleaf interchange of I-87 exit 2 and runs along the eastern edge of the expressway to exit 4 (County Route 151, Albany Shaker Road) southeast of Albany International Airportmarker. Wolf Road serves as a main access point for Colonie Center, one of the Capital Districtmarker's largest enclosed shopping malls, from I-87. Between exits 1 (where I-87 begins on the Northway), to exit 22 (at Lake George Village) I-87, both north and south, is a six-lane corridor.

The southern portion of the Northway through Colonie and Saratoga Countymarker is now a heavily traveled commuter route. Since the highway's construction, Saratoga County has become the fastest growing area of the Capital Districtmarker, and indeed all of upstate New York.

In Lake Georgemarker, I-87 connects to US 9 and New York State Route 9N at exit 22 by way of a short two-lane highway known infrequently as the Lake George Connector. It's here where the first signs of Quebec Autoroute 15 are posted as motorists head North to Canada. From here the Northway becomes four lanes all the way to the Canadian border (with the highway, both north and south slightly becoming six lanes once again just before the customs).

At milepost 100 on southbound I-87, there is a United States Customs border patrol station. This was added after the 2001 terrorist attacks.

In Clinton Countymarker, exit signs from Exit 34 to 43 are bilingual in English and French due to its proximity to Quebecmarker. Also, signs for Quebec Autoroute 15 are posted on I-87 North as the Northway approaches the Canadian border.


Interstate 87 was assigned on August 14, 1957, as part of the establishment of the Interstate Highway System. The highway initially utilized the pre-existing New York State Thruway from Albanymarker to Newburghmarker and in lower Westchester Countymarker, and the Major Deegan Expressway in New York Citymarker. From Newburgh to the Elmsfordmarker area, I-87 was to follow a new highway paralleling U.S. Route 9 northward along the eastern bank of the Hudson River to Fishkillmarker. I-87 would then follow the proposed I-84 across the Hudson to rejoin the Thruway outside of Newburgh. Meanwhile, the entirety 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.

Adirondack Northway

The Northway 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 NY 7 near Lathammarker. This segment was open to traffic by 1960, by which time work had begun on two additional segments from Latham to Maltamarker (at NY 67) and from US 9 in northern Saratoga Countymarker to US 9 and NY 149 midway between Glens Fallsmarker and Lake Georgemarker. The expressway was completed between Latham and Clifton Parkmarker (NY 146) and from US 9 south of Glens Falls to the Hudson River ca. 1961. Work on the Latham–Malta and US 9 – NY 149 segments concluded ca. 1962. Construction on the portion of highway between the two segments began ca. 1962 and was completed by 1964. During this same period, another extension brought the northern terminus of the Northway to NY 9N south of Lake George.

By 1966, the Northway was completed from Albany north to Lake George and from the Canadian border south to Keesevillemarker. At the time, I-87 curved around the outskirts of Lake George to end at NY 9N north of the village on a highway built ca. 1964. The last section of the Northway to be built—a stretch between Underwood (exit 30) and Keeseville (exit 34)—was completed in spring 1967. I-87 was reconfigured slightly near Lake George as a result: instead of heading east to NY 9N, it continued north on a parallel routing to US 9. I-87's former routing to NY 9N, known infrequently today as the Lake George Connector, is now NY 912Q, an unsigned reference route in length. NY 912Q has one intermediate interchange with US 9.

The completion of I-87 linked New York Citymarker to Montrealmarker by way of a direct, limited-access highway (with I-87 becoming Autoroute 15 at the Canadian border). It was finished just in time for Expo 67, a World's Fair-style event held in Montreal from April to October 1967.

Parade Magazine designated the Northway as America's Most Scenic Highway in 1967. In 2007, the New York State Department of Transportationmarker (NYSDOT) ceremonially designated the entire Northway as the Adirondack Veterans' Memorial Highway.

A long stretch of the Northway through the Adirondack Park has been a dark zone for cell phone service. In 2007, a driver crashed off the road was unable to summon help, prompting calls from local officials to add new wireless towers to address the problem, and warning signs to inform drivers of the dark zone. Throughout this area, roadside emergency call boxes are located approximately every two miles on both sides of the roadway. These boxes use a 2-way UHF radio network to connect directly to New York State Police dispatch. As of 2008, a series of cell towers is being installed.

Fuller Road Alternate, the lone portion of the Adirondack Northway not part of I-87, was originally intended to be part of the Southern Albany Expressway, a proposed highway which would have connected the Northway to Interstate 787 and run parallel to the New York State Thruway between exits 23 and 24.

Lower Hudson Valley

By 1962, the plan to route I-87 along the proposed Hudson River Expressway had been scrapped. Instead, I-87 was now proposed to begin in Port Chestermarker and follow a new routing through Purchasemarker, Armonkmarker, and Katonahmarker to Brewstermarker, where it would join I-84. The routing was modified slightly by 1968: I-87 still began in New York City, then overlapped Interstate 287 east to Purchase. From there, I-87 headed north along the now-open expressway to Armonk, where it ended at NY 22. Another portion of the highway, from Goldens Bridge (NY 138) to Brewster, was open as well while the part from Armonk to Katonah was under construction. This segment, as well as the part from Katonah to Goldens Bridge, was completed by 1971.

On January 1, 1970, I-87 was rerouted between Elmsford and Newburgh to follow the mainline of the Thruway instead. The former routing of I-87 between Purchase and Brewster was then redesignated as Interstate 684.


NYSDOT is constructing a single-point urban interchange (SPUI) at Northway exit 6 to replace the current diamond interchange.

A project is in the early stages of design to improve access to the Albany International Airportmarker, either by constructing a new exit 3, or by reconfiguring exit 4. As of January 2009, the project is expected to be completed in 2015.

Auxiliary routes

Interstate 487 (Hudson River Expressway) was planned to be the I-87 of the east-side of the Hudson. It was planned to run from where I-87 crosses the Hudson at the Tappan Zee Bridge to I-84 in the City of Beacon, NYmarker. It was on the books as a project from the 1930s until the later 1970s. The Croton Expressway along US 9 between Croton-on-Hudsonmarker and Peekskillmarker is the only section ever built.

Interstate 687 was planned as a bypass around Albany, New Yorkmarker, but it was never built. The interchange that connects Corporate Woods Boulevard to I-90 was intended originally for I-687. Also, there is still no exit 3 on I-87. This was also intended for 687.
