107-736: Interstate 287 ( I-287 ) is an auxiliary Interstate Highway in the US states of New Jersey and New York . It is a partial beltway around New York City , serving northern New Jersey and the counties of Rockland and 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 ( I-95 ) in Edison, New Jersey , clockwise to

214-464: A loop route ) completely surrounds a metropolitan city, and it is often connected with multiple junctions to other routes. Unlike other auxiliary Interstate Highways (and by extension, all primary Interstate Highways ), beltways do not have termini; however, they have a place where the highway mileage resets to zero. Beltways are also preceded by an even number in the first digit. Some examples of beltways include: New Jersey Route 27 Route 27

321-591: A $ 187-million (equivalent to $ 307 million in 2023) reconstruction in 2001 in order to add additional lanes and rebuild overpasses and underpasses. Reconstruction in this area was completed in May 2004. In 2016, the Tappan Zee Bridge toll plaza was demolished and replaced with an electronic toll gantry on the west side. The Spring Valley toll plaza went all-electronic in 2018. Plans for a limited-access road to cross Westchester County east to west date back to

428-822: A ceremony held on the Wanaque River bridge, where New Jersey Governor James Florio cut the ribbon. This moment marked the completion of a bypass around New York City that had been planned for decades. The portion of I-287 between the US ;202 interchange in Oakland and the Route ;208 interchange in Franklin Lakes overtook the westernmost portion of Route 208, truncating that route to its current location. The completion of I-287 in New Jersey had significant effects on traffic and development patterns in

535-723: A crossing of the Hudson River, opened in 1955. In New Jersey, the proposed I-287 had originally been designated as FAI Corridor 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 202 in Montville opened in stages between the 1960s and 1973; the remainder was completed by 1994.

3638-613: The US Army Corps of Engineers . Officials in Rockland County, New York filed a lawsuit on November 19, 1993, hours before the highway's official ribbon-cutting, seeking to block its opening. They claimed the incomplete interchange with the New York State Thruway was inadequate to handle the additional traffic. That interchange was not complete until 1994, but the highway opened as planned on November 19 in

3745-610: 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. Construction of the freeway began in 1956, and was given the NY ;119 designation. The design of the highway met Interstate Highway standards after opening and was supposed to have the I-187 designation. However, by

3852-607: The Cross Westchester Expressway was transferred from the New York State Department of Transportation (NYSDOT) to the NYSTA in 1990 to help relieve the state's budget issues. On July 27, 1994, a propane truck crashed into an overpass on the Cross Westchester Expressway in White Plains and exploded, killing the driver. The fire from the explosion spread into adjacent neighborhoods and injured 23 people. In

3959-555: The I-287 bypass of New York City and I-95 south to Pennsylvania . On July 16, 1999, Governor Christine Todd Whitman banned oversize trucks from using roads that are not part of the National Highway System , such as Route 31. Trucks were therefore forced to use I-287 and the New Jersey Turnpike to travel across the state. In the 1990s, high-occupancy vehicle lanes (HOV lanes) were built along I-287 between Bedminster and Parsippany. These HOV lanes, along with

4066-581: The I-287 designation in 1958. The southern segment of I-287 was planned in the 1950s as the Middlesex Freeway, which was to run from the Outerbridge Crossing to Staten Island and follow the Route 440 corridor to Edison, where it would connect to the New Jersey Turnpike before continuing west to I-78. From here, the freeway would parallel US 202 north to the New York border. The anticipated cost of building I-287 in New Jersey

4173-551: The Lincoln Highway was renumbered as Route 27 between Trenton and Newark. U.S. Route 1 was designated on this portion of the road until it was relocated by the 1940s. U.S. Route 206 followed the route from Trenton to Princeton until 1953, when the southern terminus of Route 27 was cut back to Princeton to avoid the concurrency with US 206. Route 27 begins at a traffic light with US 206 in Downtown Princeton , Mercer County . The route heads northeast along Nassau Street,

4494-564: The New York State Thruway in Suffern, New York , was controversial dating back to 1965 and continuing until its opening in 1993. Property owners along the proposed route fought its completion as part of the freeway revolts of the 1960s and 1970s. Originally, I-287 was proposed to take a more eastern route through the Lincoln Park and Wayne areas; this routing gained opposition as it passed through populated areas. A more western alignment

4601-461: The New York State Thruway widens to eight lanes and turns to the south-southeast into the village of Nyack in the town of Orangetown , crossing over US 9W prior to passing near residential areas in the village of South Nyack as it runs to the east of US 9W, descending into the Palisades . The last interchange in Rockland County is with US 9W and has no southbound exit. From here,

The Cross Westchester Expressway, which is maintained by the NYSTA, is six lanes wide and carries I-287 east to a westbound exit for NY 119 that is intertwined with the ramps between the New York State Thruway and NY 119/Saw Mill River Parkway. After passing over

4815-637: The Saw Mill River Parkway and the Saw Mill River , the road enters the village of Elmsford and runs through developed areas as it has a partial diamond interchange with NY 9A that does not have an eastbound exit. The Cross Westchester Expressway turns southeast from this point and intersects the Sprain Brook Parkway . I-287 widens to eight lanes at this junction and continues to the exit for NY 100A . After

4922-461: The Tappan Zee Bridge over the Hudson River, opened on December 15, 1955. In the 1960s, I-287 was designated along the New York State Thruway between Suffern and Tarrytown, while I-87 ran farther to the east on present-day I-684. On January 1, 1970, the I-87 designation was shifted onto this portion of the New York State Thruway to run concurrent with I-287. The E-ZPass electronic toll collection system

5029-401: The United States' Interstate Highway System . The 323 auxiliary routes generally fall into three types: spur routes , which connect to or intersect the parent route at one end; bypasses , which connect to the parent route at both ends; and beltways , which form a circle that intersects the parent route at two locations. Some routes connect to the parent route at one end but to another route at

5136-545: The Vincent R. Kramer Interchange, where the local–express lane configuration ends. Access from eastbound I-78 to southbound I-287 is only to the local lanes. Meanwhile, the express lanes of northbound I-287 provides access to westbound I-78 while the local lanes provide access to eastbound I-78. Following I-78, I-287 heads north with four northbound lanes and three southbound lanes into more wooded surroundings, reaching another interchange with US 202/US 206. At this point,

I-287 reaches an interchange where the frontage road ends as Westchester Avenue heads east as NY 120A and NY 120 continues to the south. Here, the freeway enters

5350-443: The area. Several towns along the highway, such as Wanaque and Montville, saw increases in development. In addition, as the road was a bypass, it saw a significant increase in truck traffic wishing to bypass congested roads closer to New York City. The road also increased truck traffic on other north–south corridors, such as Route 31 , from truckers wanting to bypass the New Jersey Turnpike by using these surface roads to get between

5457-604: The bridge carried fewer than 40,000 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 million (equivalent to $ 719 million in 2023). Unlike other major bridges in the New York metropolitan area , the Tappan Zee was designed to last only 50 years. The Federal Highway Administration (FHWA) issued

Route 27 moves through downtown Princeton, passing by the main gates to Princeton University near Nassau Hall , and intersecting with Washington Road ( CR 526 / CR 571 ). After leaving

7597-442: The mid-1990s, a reversible HOV lane was proposed for the Cross Westchester Expressway in order to alleviate congestion at a planned cost of $ 365 million (equivalent to $ 667 million in 2023). In addition, a Metro-North Railroad line and a guided busway were considered to serve the I-287 corridor in Westchester County as alternatives to the HOV lane. The proposed HOV lane was cancelled in 1997 by Governor George Pataki out of

7704-431: The mountains into suburban residential and commercial surroundings as it narrows to six lanes. After passing through the village of Montebello , the freeway reaches an interchange with Airmont Road where it becomes the border between Montebello to the north and the village of Airmont to the south.

The route crosses into Linden when passing

8132-433: The numbers can repeat from state to state along their route, but they will not repeat within a state. There are three states that have no auxiliary Interstate Highways: Alaska, Arizona, and New Mexico. North Dakota has an auxiliary route, but it is unsigned , and Wyoming's does not meet Interstate Highway standards. Auxiliary Interstates are divided into three types: spur , loop , and bypass routes. The first digit of

8239-526: The old bridge until October 6, 2017. At that point, southbound/eastbound traffic shifted to the westbound span of the new bridge and the old bridge closed. The bridge's eastbound span opened to traffic on September 11, 2018. Upon completion, the new Tappan Zee Bridge became one of the longest cable-stayed spans in the nation. In 2008, a private firm, Polimeni Associates, proposed to construct a more than 16-mile-long (26 km) tunnel across Long Island Sound between Rye and Oyster Bay. This proposed tunnel would be

8346-426: The one-way pair, Route 27 resumes east on four-lane Westfield Avenue, turning north onto Broad Street. The route heads into a more urbanized setting and continues northeast onto Newark Avenue, intersecting with the northern terminus of Route 439, where that route heads west on North Avenue. Through Elizabeth, about 10,000 to 20,000 vehicles travel on Route 27 every day. Route 27 crosses into Newark , Essex County at

8453-539: The ones that had been built on I-80, were opened to all traffic in 1998 due to lack of HOV usage, and the state did not have to repay the federal government the $ 240 million (equivalent to $ 419 million in 2023) to build the lanes. In 2011, a small section of the northbound side of the highway in Boonton collapsed into the Rockaway River due to Hurricane Irene . Near the end of that year, five people and

8560-687: The other end; some states treat these as spurs while others treat them as bypasses. Like the primary Interstate Highways , auxiliary highways meet Interstate Highway standards (with rare exceptions ). The shorter auxiliary routes branch from primary routes; their numbers are based on the parent route's number. All of the supplement routes for Interstate 95 (I-95) are designated with a three-digit number ending in "95": I-x95. With some exceptions, spur routes are numbered with an odd hundreds digit (such as I-395 ), while bypasses and beltways are numbered with an even hundreds digit (such as I-695 ). Because longer Interstates may have many such supplemental routes,

8667-505: The right to resume its northeast direction. Route 27 intersects with Main Street ( CR 531 ) after 0.2 mi (0.32 km) and continues northeast on Middlesex Avenue, passing through a residential environment where the route carries about 22,414 vehicles daily. The road comes to a bridge over Conrail Shared Assets Operations ' Port Reading Secondary line. The route crosses back into Edison and becomes Lincoln Highway again, passing over

8774-680: The river, there is an interchange with CR 527 . After CR 527, the freeway makes a turn to the northwest and passes a mix of residential areas and business parks. The road has an interchange with CR 623 (Weston Canal Road) before crossing the Raritan River again and continuing into Bridgewater Township . Within Bridgewater Township, I-287 curves north-northwest and passes over Conrail Shared Assets Operations's Lehigh Line and then both NJ Transit 's Raritan Valley Line and CR 533 near TD Bank Ballpark , which

8881-572: The road crosses into White Plains and reaches an interchange with NY 22 . Past NY 22, I-287 makes a sharp curve to the south as it narrows to six lanes and runs near inhabited neighborhoods. The road has a westbound exit and eastbound entrance with the Central Westchester Parkway , a road that provides access to the Taconic State Parkway by way of NY 22. The freeway runs past commercial areas to

8988-558: The road passes corporate parks to the north and populated neighborhoods to the south. The road begins to turn southeast as it comes to a directional interchange with the southern terminus of I-684 . The I-287 freeway heads south along the White Plains–Harrison border before turning east and fully entering Harrison, where there is a cloverleaf interchange with the Hutchinson River Parkway . At this interchange,

9095-541: The road passes to the north of Nanuet , crossing under NJ Transit/Metro-North Railroad's Pascack Valley Line . The freeway crosses under NY 304 before the cloverleaf interchange with the Palisades Interstate Parkway .

9202-561: The road runs under NJ Transit's Gladstone Branch , heading more to the northeast. Before leaving Bernards Township, there is an exit for North Maple Avenue. A short distance after this interchange, I-287 enters Harding Township , Morris County , at the crossing of the Passaic River , where it becomes the Marine Hector Cafferata Jr. Cong. Medal of Honor Highway. It continues northeast, with US 202 running

9309-403: The road turns more to the northwest and passes under Conrail Shared Assets Operations 's Bonhamtown Industrial Track line and a railroad spur before it comes to the junction with Route 27 ( Lincoln Highway ). Following Route 27, I-287 narrows to six lanes and passes over Amtrak 's Northeast Corridor as it continues to a southbound exit and northbound entrance with CR 501 . As

9416-709: The route heads east along that road to its northern terminus at an interchange with McCarter Highway ( Route 21 ) and Broad Street. The southern part of Route 27 follows the Lenape Assunpink Trail that during the colonial era was known as the Old Dutch Trail, and later became the Kings Highway . North of Rahway, the road was created as Queen Anne's Road, running from Perth Amboy to Elizabethtown Point , with later extensions to Newark and Jersey City. This road would have several names over

9523-661: The sections from US 46 south to Route 10 in Hanover Township and from Bedminster north to Maple Avenue in Bernards Township opened. The segment of the highway between Maple Avenue and Route 24 opened in 1973, followed by the segment between Route 24 and Route 10 in early 1975, making I-287 a continuous road between the New Jersey Turnpike in Edison and US 202 in Montville. I-287's missing section between US 202 in Montville and

9630-410: The southbound direction gains a fourth lane as the median narrows. The freeway enters more developed areas as it comes to the Route 124 interchange. From this point, the road becomes eight lanes total, with four in each direction, as it passes west of Morristown Medical Center . After crossing under NJ Transit's Morristown Line , it reaches the exit for CR 510 . From CR 510, I-287 makes

9737-402: The southbound local and express lanes have access to southbound US 202/US 206 at this interchange, whereas northbound US 202/US 206 only has access to the local lanes of northbound I-287. From here, the road continues north past suburban residential areas, with the northbound direction narrowing to two local lanes, before entering Bedminster . Here, I-287 intersects I-78 at

9844-422: The standard numbering guidelines exist for a number of reasons. In some cases, original routes were changed, extended, or abandoned, leaving discrepancies in the system. In other cases, it may not be possible to use the proper number because the limited set of available numbers has been exhausted, causing a "non-standard" number to be used. A spur route 's number usually has an odd number for its first digit. It

9951-504: The terrain starts to get more mountainous. This stretch of I-287 continues for six miles (9.7 km) before its next exit. The freeway runs through Kinnelon , where the northbound direction has four lanes, and Pequannock Township before entering Riverdale . In Riverdale, there is an interchange with Route 23 . A short distance later, I-287 reaches the CR 694 interchange which provides access to CR 511 Alternate (CR 511 Alt.). Immediately after this, I-287 crosses over

10058-521: The three digits usually signifies whether a route is a bypass, spur, or beltway. The last two digits are derived from the main Interstate Highway. For instance, I-115 contains an odd number in the first digit (1), which indicates that this freeway is a spur. The last two digits signify the highway's origin. In this case, the "15" in I-115 shows that it is a supplement to I-15 . Exceptions to

10165-476: The time the highway opened, it was officially designated as I-487 instead. At a cost of $ 50 million (equivalent to $ 395 million in 2023), the Cross Westchester Expressway was opened December 1960. Later in the 1960s, this segment of road was redesignated I-287 to make it a part of the beltway around New York City. I-287 was to continue past I-95 in Port Chester and was to cross Long Island Sound via

10272-645: The unbuilt Oyster Bay–Rye Bridge . On Long Island , the route would run along the Seaford–Oyster Bay Expressway ( NY 135 ). Then, I-287 was again to be extended into Jones Beach by merging with the Wantagh State Parkway in Merrick . 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. Ownership of

10379-464: The village of Chestnut Ridge to the south as it turns slightly to the east-southeast. After briefly running along the south edge of the village of Spring Valley , where there is a westbound toll gantry for trucks, the highway fully enters Chestnut Ridge. In this area, it comes to the Thruway's Garden State Parkway Connector . Following this junction, I-87/I-287 continues east into the town of Clarkstown , coming to an exit for NY 59 . After this,

10486-415: The village of Rye Brook in the town of Rye as it continues southeast. The Cross Westchester Expressway comes into the village of Port Chester , where the road runs near more dense suburban development as it intersects US 1 . At this point, the road has ramp access to and from the southbound direction of the New England Thruway ( I-95 ). From here, the mainline I-287 narrows to four lanes and enters

10593-623: The west and South Brunswick , Middlesex County to the east, passing through the historic community of Kingston .

10700-550: The west and business parks to the east. Upon entering New York in the village of Hillburn in the town of Ramapo in Rockland County, New York , New Jersey's Route 17 ends and NY 17 follows I-287 as the road comes to an interchange with the New York State Thruway ( I-87 ). At this point, NY 17 splits north onto I-87 and I-287 joins I-87 on the eight-lane New York State Thruway, passing over Metro-North Railroad 's Port Jervis Line as it heads east out of

10807-545: The west and runs to the north of US 22 as it has a wide median. The freeway turns northwest as it passes near the Bridgewater Commons shopping mall and reaches a partial interchange with US 202 / US 206 . Through the remainder of New Jersey, US 202 parallels the course of I-287. At this point, I-287 gains a local–express lane configuration, with three local and two express lanes southbound and three express and three local lanes northbound. Both

10914-643: Was $ 235 million (equivalent to $ 2.09 billion in 2023). The southernmost part of I-287 in Middlesex County was intended to be signed as part of I-95 instead; this never happened due to the cancellation of the Somerset Freeway . By the mid-1960s, I-287 had been completed between the New Jersey Turnpike and Bedminster and from US 46 in Parsippany to US 202 in Montville. More of I-287 in New Jersey had been finished by 1969, with

11021-537: Was first introduced on this segment of the Thruway at the Spring Valley and Tappan Zee Bridge toll plazas in 1993. The same year, an interchange in Suffern opened providing access to the newly opened New Jersey portion of I-287. In 1997, tolls for cars were eliminated at the Spring Valley toll plaza, with tolls remaining for trucks and other commercial vehicles. The I-87/I-287 interchange split near Tarrytown began

11128-489: Was part of the alignment through New Jersey of the Lincoln Highway , the United States' first transcontinental highway that was established in 1913. Route 27 is still referred to as the Lincoln Highway in many municipalities, such as Edison . The Lincoln Highway became part of pre-1927 Route 1 between New Brunswick and Elizabeth in 1916 and pre-1927 Route 13 between Trenton and New Brunswick in 1917. In 1927,

11235-486: Was planned around 1950 as part of a tolled limited-access highway that was to connect the major cities of New York. A bridge across the Hudson River was planned between Nyack and Tarrytown at a site that was close enough to New York City but far enough from the Port Authority of New York and New Jersey 's jurisdiction area, as they opposed the crossing. The portion of the Thruway currently followed by I-287, including

11342-468: Was planned through mountainous areas in 1973, but this was rejected as the cost of building the road through the mountains was too high. In 1977, the current alignment of I-287 was proposed between Montville and Suffern; this was approved by the federal government in 1982 as it was less costly than the western alignment and went through less developed areas than the eastern alignment. Permits allowing construction to begin on this segment were issued in 1988 by

11449-603: Was replaced with a new span which opened in stages between 2017 and 2018. A proposed tunnel across the Long Island Sound between Rye and Oyster Bay on Long Island would link the eastern terminus of I-287 to New York State Route 25 (NY 25) and NY 135 in Syosset . I-287 begins at an interchange with the New Jersey Turnpike ( I-95 ) in Edison in Middlesex County, New Jersey , where
