New York State Route 27 (abbreviated NY 27) is an east–west 122.28-mile (196.79 km) long state highway extending from Interstate 278 in the New York City borough of Brooklyn to Montauk Point State Park on Long Island, New York, United States. Its two most prominent components are Sunrise Highway and Montauk Highway.

East of the interchange with the Heckscher State Parkway in Islip Terrace, NY 27 acts as the primary east–west highway on southern Long Island.

The entire route in Suffolk, Nassau, and Queens was designated by the New York State Senate as the POW/MIA Memorial Highway.

Every township on the South Shore is accessible through Sunrise Highway.


Route description


New York City

Route 27 begins at Interstate 278 (Gowanus Expressway) in the New York City borough of Brooklyn and uses the Prospect Expressway to the end of the expressway, which continues south as Ocean Parkway. NY 27 makes its way east to Linden Boulevard via Caton Avenue. Eastbound traffic exits at Fifth Street and makes a left onto Caton Avenue, crossing over the Prospect Expressway, while westbound NY 27 turns south on Coney Island Avenue and west on Church Avenue to meet the expressway's south end. Eastbound trucks are directed to exit earlier, at 10th Avenue, and take McDonald Avenue south to Caton Avenue.

Linden Boulevard enters Queens and merges into Conduit Avenue. Conduit Avenue soon splits as frontage roads for the Belt Parkway, running east past the north end of John F. Kennedy International Airport. Near the city line, the Belt Parkway turns north, and NY 27 becomes the Sunrise Highway.

Sunrise Highway

The Sunrise Highway begins in eastern Queens as a six to eight lane arterial. It heads east into Nassau County, passing through Valley Stream and Rockville Centre on its way to Merrick, where it connects to the Meadowbrook State Parkway by way of an interchange. NY 27 continues into Suffolk County, where it veers to the northeast to bypass Copiague to the north. At an interchange with NY 109 in West Babylon, the Sunrise Highway becomes a six-lane expressway with two two-lane service roads. The route continues on, meeting the Robert Moses Causeway near West Islip. In East Patchogue, New York, the highway is reduced to a four-lane expressway after the NY 112 exit. Between County Route 16 in Brookhaven and CR 46 in Shirley, the median is lined with pine trees in front of South Haven County Park. The setting along these roads is similar to the one on the Southern State Parkway west of Belmont Lake State Park. The last exit that the Sunrise Highway has with a state highway is near Hampton Bays, where it meets NY 24.

The Shinnecock Squeeze

Until April 2008 Route 27 abruptly became a three-lane highway east of the Shinnecock Canal in Southampton. This has been called the "Shinnecock Squeeze". At this point, NY 27 becomes concurrent with County Road 39. The "squeezed" lane was the east bound where two lanes became one.

Sunrise Bridge over the Shinnecock Canal

In 2006 and 2007 Suffolk and Southampton officials began using traffic cones to adjust the lanes to accommodate peak travel in what was called the "traffic cone program." At the end of the 2007 summer, work began on adding another east bound lane to the North Sea Road. The construction snarled traffic on 39 and the LIRR added three trains each way going from Speonk to East Hampton during the construction.[3] The new eastbound lane opened in April 2008. The road is now a four-lane highway to just east of Southampton Village where it becomes a two-lane.

Montauk Highway

The Montauk Highway is name NY 27 carries from just east of Southampton by the Princess Diner to the east side of Montauk, New York where it becomes the Montauk Point State Parkway, a Robert Moses design leading to Montauk Point State Park. This entire section is two lanes wide, with the exception of some four-lane sections in hamlets and the village of East Hampton.


NY 27 was signed as early as 1926 on its current alignment (excluding realignments) from the New York City line to Amagansett. East of Amagansett, the modern routing of NY 27 was unnumbered.[2] Between 1926 and 1930, NY 27 was extended eastward to its current terminus at Montauk Point.[2][4] In December 1934, the route was extended west into New York City.[5] NY 27 followed Sunrise Highway, Linden Boulevard, and Flatbush Avenue to the Manhattan Bridge.[6] On January 1, 1970, NY 27 was rerouted to enter Manhattan by way of the Gowanus Expressway and the Brooklyn–Battery Tunnel. It then followed West Street to the Holland Tunnel, where it ended at Interstate 78 and NY 9A.[7] This extension was never shown on maps,[8][9] and NY 27 was truncated to the interchange between the Gowanus and Prospect Expressways by 1981.[10]

The Montauk Highway was the original name for the route to the east end. The original Montauk Highway route has been designated New York State Route 27A and runs roughly a mile to the south of NY 27 for most of its length.

NY 27A once included what is now Suffolk County Routes 80 and 85, which assume the Montauk Highway name after NY 27A's eastern terminus at NY 27 in Oakdale. The interchange between NY 27 and NY 27A at this point is dubbed the "Oakdale Merge", and is known as a bottleneck for local traffic.

Sunrise Highway is built over the Brooklyn Waterworks aqueduct.[11]. Said aqueduct goes past the south side of Aqueduct Racetrack.

Older interchanges and crossings


Plans to construct a cloverleaf interchange with Suffolk County Route 2 (Straight Path) have existed for some time. However, in recent years, planners have realized that such an interchange would be too close to the cloverleafs with Suffolk County Route 47 (Great Neck Road) to the west and Suffolk County Route 3 (Wellwood Road) to the east. To further complicate matters, a widened Suffolk County Route 28 was extended to Sunrise Highway near the Straight Path intersection in the late-1980s. No interchange has been built yet for this area.

West Islip

The original interchange with the Robert Moses Causeway had two parkway-style arch bridges over two lanes of NY 27. When the service roads were built in Western Islip Township between 1969 and 1972, parkway-style bridges were added for them as well.

The interchanges at Fifth Ave and Brentwood Road in Bay Shore had parkway-style arch bridges as well as cloverleafs. When the service roads were added, the parkway-style bridges were removed and replaced with more modern style structures that exist today. The original cloverleafs were modified to align with the new service roads

Islip Terrace

As with the interchanges to the west, Islip Avenue (New York State Route 111) and Carleton Avenue (Suffolk County Route 17) originally had parkway-style bridges crossing over Sunrise Highway. However, only Islip Ave had a partial clover leaf on the west side of the bridge. The eastern side of the bridge used side streets for access, as did both sides of the Carleton Ave bridge. This section of Sunrise Highway wasn't even divided. Since 1983, both have much more modern bridges over service roads, and the old cross streets connect to those service roads and other side roads instead. Islip Avenue connects to NY 27 at exit 45 while Carleton Avenue meets the Sunrise Highway at exit 46.

Patchogue area

While none of the interchanges north of Patchogue were built until the period between 1988 and 1993, the New York State Department of Transportation (NYSDOT) had known the need for them and planned them decades before their eventual construction.

  • Waverly Avenue (Suffolk County Route 19) was originally proposed as a cloverleaf interchange. Today, exit 52 with CR 19 is a diamond interchange instead.[12][13]
  • North Ocean Avenue (Suffolk County Route 83) was originally proposed to be accessible via connecting ramps to side streets such as Austin Avenue along the eastbound lane and Sinn Street along the westbound lane. Today, exit 53A is a half-diamond interchange while Austin Avenue and Howard Avenue are dead end streets. Sinn Street never reached North Ocean Avenue.
  • Maple Avenue crossed the median on NY 27 between North Ocean Avenue and NY 112 until 1975. This road could also have been used as potential connecting ramps to both roads. Today, the north section only intersects the westbound service road, while the south section was convered into a dead end street north of Austin Avenue.
  • New York State Route 112 was originally proposed to be accessible via connecting ramps to side streets such as Franklin Avenue along the eastbound lane[12] and an extension of Sinn Street along the westbound lane. Sinn Street was acquired by NYSDOT east of Route 112 in the early-1960s, and was gradually abandoned.[13] Today, exit 53 is a diamond interchange instead, and Sinn Street, Austin Avenue, and Franklin Avenue are dead end streets.
  • Washington Avenue and Phyllis Drive were also originally proposed to be accessible via connecting ramps to side streets such as Franklin Avenue along the eastbound lane and an extension of Sinn Street along the westbound lane. Phyllis Drive was actually part of NY 27 until Sunrise Highway was extended to Eastport in 1957.[13] Today, both roads are only accessible to the service roads. Some residents have been waiting for a potential pedestrian bridge connecting the two ends of Washington Avenue.

South Haven

West of the Carmans River near South Haven County Park, there was once a plan to combine the eastbound service road with Montauk Highway, in a similar manner to that of the Oakdale Merge.

The Atlantic Expressway

Robert Moses developed plans for an elevated expressway along Sunrise Highway through Nassau County which was to feature 10 to 12 lanes. The downtown villages along the route effectively put a stop to the idea. This expressway would have provided a truck link for the South Shore of Long Island.

East of the Shinnecock Canal

First proposals for an extension came in the 1950s. In 1969, the New York Legislature approved a $160 million plan for the extension for the limited access route to be flanked by bicycle and equestrian trails. The eastbound and westbound roadways were to be separated by wide wooded medians. For the most part, the road would have run a mile or two to the north of existing Route 27, thus avoiding the populated centers through which it now goes.

The exits would be:

  • EXIT 67: Suffolk County Road 39 (County Road) and Suffolk CR 38 (North Sea Road)
  • EXIT 68: Suffolk County Road 79 (Bridgehampton-Sag Harbor Road)
  • EXIT 69: New York State Route 114 (East Hampton-Sag Harbor Turnpike)
  • EXIT 70: Suffolk County Road 40 (Three Mile Harbor Road)
  • EXIT 71: Suffolk County Road 45 (Amagansett-Springs Road)
  • EXIT 72: existing New York State Route 27 (Montauk Highway)

The plan failed and Governor Hugh Carey cancelled it in 1975. Other suggestions have included building a limited access road on either side of the Long Island Rail Road Montauk Branch.

Former segments

Former segments include Old Sunrise Highway (NY 900D), between the western terminus of NY 27A in Massapequa and NY 110 in Amityville, and Suffolk County Route 36 (South Country Road) between East Patchogue, New York and Brookhaven, New York, which was part of Montauk Highway until July 19, 1932. This segment runs through the downtown section of the historic village of Bellport, New York.[2] Other old NY 27's include former segments of Montauk Highway and local streets that connected Sunrise and Montauk Highways such as Phyllis Drive in East Patchogue and Suffolk CR 51 in Eastport.
