-
The following is a list of county routes in Suffolk County, New York from Routes 51 to 75.
County Route 51
County Route 51
Location: East Moriches-Riverhead Length: 8.68 mi[1] (13.97 km) Existed: 1933–present Suffolk County Road 51 is a major county road in Suffolk County, New York. It runs northeast and southwest from County Route 80 to New York State Route 24 and County Route 94 in Riverhead.
Route description
The road begins at Suffolk County Road 80(Montauk Highway), just north of the eastern terminus of Suffolk CR 98(Frowein Road). It runs along the west side of two local airports; Lufker Airport and Spadaro Airport, where it also crosses the former right-of-way for the Manorville Branch of the Long Island Rail Road. At Sunrise Highway, Suffolk CR 51 is one of the roads served by the incomplete exit 61. The other one is Suffolk CR 55, which served as part of NY 27 until Sunrise Highway was extended east of the interchange. Suffolk CR 51 became the northern terminus of Suffolk CR 55 in the 1980s.
The road continues northeast through the hills of the Long Island Pine Barrens. A long dirt road named Toppings Path veers to the left heading through preserved state and county land toward Calverton near exit 71 of the Long Island Expressway. The next site is a Half-Diamond interchange with Suffolk CR 111.
The formerly proposed western extension of Suffolk County Road 105 was supposed to cross Suffolk CR 51 near Bald Hill (not to be confused with Bald Hill in Farmingville), which towers at 302 feet (92 m) in elevation. The western terminus of a former section of the road is believed to be where part of the interchange was intended. The intersection of Speonk-Riverhead Road(former SCR 88) leads to the Suffolk County Community College Eastern Campus. Northeast of that point, the road literally starts to go downhill.
At Wildwood Lake, there was an at-grade interchange with Suffolk CR 63(Lake Avenue), which used to be part of East Moriches-Riverhead Road. The ramp that used lead to CR 63 has since been transformed into a cul-de-sac. From there the road runs north through Cranberry Bog County Park. It curves northeast again at a plot of land that was originally intended to be the southern terminus of Suffolk CR 103(Cedar Swamp Road), then enters a series of Suffolk County Government buildings where it finally terminates at a traffic circle along New York State Route 24-CR 94 in Riverhead.

Today it serves as a southbound only suffixed route of Suffolk County Road 13, known as Suffolk County Road 13A south from the intersection of Reil Place. North of this intersection, Clinton Avenue is a string of roads running parallel to Fifth Avenue maintained by the Town of Islip.
County Route 54
County Route 54
Location: Calverton-Wading River Existed: 1935–present Suffolk County Route 54 is mainly Hulse Landing Road a two-lane road that runs north and south from Calverton to Wading River.
The road begins on New York State Route 25A near land formerly owned by the Calverton Naval Weapons Industrial Reserve Plant. Between NY 25A and Sound Avenue the formerly proposed Nugent Drive Extension was supposed to cross over Suffolk CR 54 at an interchange. The Nugent Drive Extension was intended to serve as the relocated NY 25A. Soumd Avenue was to be transformed into a dead end street west of CR 54. Today, the land intended to be used for the road is now part of a housing development.
Though Hulse Landing Road head straight north toward Old North Country Road along the western border of Wildwood State Park, Suffolk County Road 54 curves northeast into Wildwood Road, the southern entrance of the park.

Location: Eastport Existed: 1935(1953, 1986)–present Suffolk County Route 55 is a short county road in Suffolk County, New York located in and around Eastport, New York known as Eastport-Manor Road, and sometimes Eastport-Manorville Road. It runs north and south from Suffolk CR 80 (Montauk Highway, formerly New York State Route 27A) to Suffolk CR 51 north of Eastport. Despite its diminutive length, it packs quite a history.
History
As the name implies, the road originally went from Manorville to Eastport, New York, and was acquired by the Suffolk County Department of Public Works in 1935. The section between Montauk Highway and Suffolk CR 71(Old Country Road) was once part of Montauk Highway itself. When Sunrise Highway terminated at Exit 61, NY 27 took a right turn along a temporary concurrency with Suffolk CR 55 until it reached Montauk Highway, and continued eastward toward Montauk.[3]
Construction of the vast and complex Exit 61 interchange forced the realignment of Suffolk CR 55, as well as Head of the Neck Road.[4] When Suffolk CR 111 was built between the Long Island Expressway and Sunrise Highway during the 1970s, it replaced Eastport-Manorville Road north of the road's current terminus towards the L.I.E. However, Suffolk County Planning Department wanted to build a new extension of Suffolk CR 55 north of Suffolk CR 111 leading to the Grumman Calverton Airport. An interchange with the expressway was also supposed to have been built.[5] Neither of these proposals were ever accepted.
Suffolk CR 55 was truncated to East Moriches-Riverhead Road in 1986, and the rest of Eastport-Manor Road fell under the jurisdiction of the Town of Brookhaven. This section is the home to the Shrine of Our Lady of The Island.

County Route 56
Location: Brookhaven-Shirley Length: 2.20 mi[6] (3.54 km) Existed: 1960–present Suffolk County Route 56 is an unmarked bi-directional frontage road along NY 27 known as Victory Boulevard. It stretches from Suffolk CR 16 between Sunrise Highway and Suffolk CR 21 and ends at William Floyd Parkway, however Victory Boulevard extends east of the SCR 56 designation. At one time, it also included Horse Block Road east of Waverly Avenue.
CR 56 provides the entrance to South Haven County Park along Carmans River, and the median of Sunrise Highway near this section contains a pine tree lined median in front of those entrances. The setting along these roads is similar to the one on the Southern State Parkway west of Belmont Lake State Park. After the intersection of River Road, a westbound on-ramp to Sunrise Highway, which was originally built with two different access points.
East of the William Floyd Parkway interchange, Victory Boulevard remains a two-lane bi-directional frontage road for Sunrise Highway, but this section is a Town of Brookhaven maintained road. It skirts along the south end of the runway for Brookhaven Airport west of Winters Drive, and goes as far east as Barnes Road in Moriches.

County Route 57
Location: Deer Park-Bay Shore Length: 4.61 mi[6] (7.42 km) Existed: 1935 (1936, 1967)-–present Suffolk County Route 57 runs mostly east and west from New York State Route 231 in Deer Park to New York State Route 27A in Downtown Bay Shore. It includes Bay Shore Road, Howell's Road, and Third Avenue.
Route description
No sooner does County Road 57 start at NY 231 in a sharp southeasterly direction, does it encounter Carll's Path and Commack Road. The intersection of Weeks Road is where the road crosses the Babylon-Islip Town Line, the southeastern angle of the road levels off, and was where the Babylon-Northport Expressway was intended to cross over, with a possible interchange. County Road 82's northern terminus is at CR 57, however Udall's Road continues north of this terminus as a Town of Islip Street. Howell's Road is cut off by the interchange with the Southern State Parkway. Originally it crossed Bay Shore Road, then moved along the south side and intersected with Bay Shore Road again along with Nuncey Road. Besides serving Exits 41 W-E on the Southern State, it also contains on and off-ramps from the ramp between Robert Moses Causeway and Heckscher State Parkway.
At the intersection of Nuncey Road, Suffolk CR 57 moves from Bay Shore Road to Howell's Road. From there it becomes the northern border of the Village of Brightwaters. Eastbound and westbound carriageways are separated by two different underpasses beneath the interchange with Sunrise Highway, both of which briefly join the service roads. When the eastbound and westbound lanes merge again, the first site the encounter is The John Thomas Inne on the southeast corner of Howell's Road and the eastbound service road. At Manatuck Boulevard, the Brightwaters Village Line moves from the north side of CR 57 to the south side, but still runs along the road until Clinton Avenue, where CR 57 leaves Brightwaters just west of the intersection of Suffolk CR 13. Suffolk CR 57 turns south onto Third Avenue, where it crosses Suffolk CR 50, and finally terminates at New York State Route 27A in Downtown Bay Shore.

The road was decommissioned and is now maintained by the Town of Islip.
County Route 58
County Route 58
Location: Calverton-Riverhead Length: 4.5 mi[1] (7.24 km) Existed: 1936–present Suffolk County Route 58 is Riverhead's Old Country Road. It serves as a northern bypass of the section of NY 25 that runs through the downtown area of Riverhead. Built through what were once relatively desolate fields, the road is now home to several large shopping centers and big box stores, and as such, has become, at least on the weekends, even more choked than the road it is supposed to bypass.[7]
Route description
The highway starts at the sprawling junction of NY 25 and I-495, as a four-lane divided highway. The western split between NY 25 and CR 58 is entirely grade-separated with turn-arounds in the median. This was built in conjunction with the interchanges with the Long Island Expressaway at exits 72 and 73. After the incomplete interchange with I-495 (which would have been expanded when I-495 was extended eastward), the road quickly narrows to four lanes with a center-turn lane as it passes the large Tanger Outlet Center complex, which was built during the 1990s.
Continuing eastward, the road alternates between three lanes and four lanes, always with a center turn lane. The portion of the road between the outlet center and the traffic circle at CR 73 has been the site of the most active retail development, spread over several decades. As such, the road's width and treatment vary because the task of widening largely fell to each individual developer of the new strip malls. Of course, the area is now very congested, particularly because the number of traffic lights on the road has increased from 6 in 1990 to 13 in 2007.
After the traffic circle at CR 73, the road continues for the rest of its length with only two lanes plus the center-turn lane. It terminates at NY 25 & Doctor's Path northeast of the town of Riverhead.

Location: Town of East Hampton Suffolk County Route 59 is Long Lane in East Hampton Township. It was once proposed to be extended and serve as a realigned section of NY 114.[8]
County Route 60
County Route 60
Location: Noyack-North Haven Existed: 1970's–present Suffolk County Route 60 is former Suffolk CR 38A. It is a pair of two-lane roads(Noyack-Long Beach Road and Short Beach Road) that run along the peninsula connecting Noyack, New York with North Haven, New York.
Noyack-Long Beach Road was previously known as Long and Short Beach Highway. CR 60 begins at an at-grade interchange with Suffolk County Road 38 in Noyack between Noyack Bay and Payne's Creek. It narrows down to a two-lane undivided highway which runs on a peninsula, with a parallel park access road on the north side and a bicycle lane on the south side. The western interchange indicates a potential proposal to widen the road to a possible four-lane divided highway that was never built.
The peninsula ends in North Haven, New York, where Noyack-Long Beach Road becomes Short Beach Road at Third Street. Suffolk CR 60 ends at a traffic circle at New York State Route 114 and Tyndall Road, although NY 114 continues in the same direction as Short Beach Road until it curves to the north and reaches the South Ferry Port to Shelter Island.

County Route 61
Location: Holtsville-Farmingville Existed: 1975–present Suffolk County Route 61 is unsigned Waverly Avenue, a mainly two-lane road that runs north and south along the Islip-Brookhaven Town Line until the town line makes a sharp left along the Greenport Branch of the Long Island Rail Road.
Route description
Suffolk CR 61 begins at County Route 19 (Suffolk County, New York), in the Town of Brookhaven where that section of Waverly Avenue becomes Patchogue-Holbrook Road, and Log Road becomes a dead end street. From here, road takes a northesterly turn and straightens out along the Islip-Brookhaven Town Line. County Road 61 is the last interchange along Woodside Avenue(County Route 99 (Suffolk County, New York) before it's western terminus at Patchogue-Holbrook Road. Access is only available from Woodside Avenue, however this interchange also includes a underpass for a driveway to the Holtsville I.R.S. office. Further north, motorists will encounter the southern terminus of Blue Point Road, which until the Town of Islip allowed development on the west side of the road in the mid-20th century, actually reached Blue Point, New York.
The last intersection within range of the Town of Islip is for Furrow Roads(eastern terminus of Suffolk CR 90) and Barretts Avenue, both of which were once intended to be integrated into the Central Suffolk Highway. Before the grade crossing of the Main Line of the Long Island Rail Road, a driveway for the former site of Holtsville (LIRR station), can be found on the right side, while the Islip-Brookhaven Town Line takes a left turn to follow the tracks into Ronkonkoma, and Lakeland. After this crossing, Waverly Avenue immediately crosses Long Island Avenue, which until the mid-1970s terminated at Waverly Avenue, forcing westbound motorists to make a right turn and then a left onto Union Avenue across from the Holtsville Fire Department.
Waverly Avenue crosses over the Long Island Expressway with no access other than to the service roads. However, until Nicolls Road was extended to the Long Island Expressway, it served as one of the eastbound destinations for Exit 62. On the northeast corner of the westbound service road is the Waverly Avenue Elementary School. The remainder of CR 61 is residential and wooded. Due to the lack of County Road shields, Suffolk County Road 61 ends unceremoniously at Suffolk CR 16(Horse Block Road), east of where CR 16 moves from the eastern terminus of Portion Road onto Horse Block Road. North of Horse Block Road, a town maintained extension of Waverly Avenue curves through the hills of a housing development towards College Road, at the former intersection with Highview Drive, a partial dirt road that had street name signs years after being closed off.

Location: Canoe Place Length: 0.85 mi[6] (1.37 km) Existed: 1936–present Suffolk County Route 62 can be found on the west side of the Shinnecock Canal along Newtown Avenue north of Montauk Highway and partially into Sunset Avenue at the Shinnecock County Marina.
Route description
Suffolk CR 62 begins as Newtown Road at a divided section of Montauk Highway(Suffolk CR 80) and is the last intersection on the highway before it crosses the Shinnecock Canal. Access to CR 62 is available from both directions on Montauk Highway, but traffic entering it can only do so from a south to westbound ramp that may've been a former segment of Montauk Highway itself. A U-Turn ramp exists for north to westbound traffic. The road then passes by some Town of Southampton Parkland, and then an 11'7" bridge beneath the Montauk Branch of the Long Island Rail Road. Further north, a local street named Gate Street leads to the only street that runs closer to the canal than Newtown Road does.
Like Suffolk CR 39B on the east side of the canal, Suffolk CR 62 runs beneath the Sunrise Highway Bridge over the canal, but has no access to that road. After passing by some marinas and shore front homes, Suffolk CR 62 seems to terminate at a "T" intersection, but in reality makes a right turn at that intersection onto Sunset Avenue. Newtown Road, on the other hand, continues northwest through part of the Shinnecock Indian Reservation along the coast of the Great Peconic Bay and then west along the south end of Squire Pond before the intersection of Squiretown Road which leads to CR 32 and the Ponquogue Bridge, and Red Creek Road, which runs along the bay again towards NY 24.

County Route 63
Location: Near Wildwood-Riverhead Length: 1.6 mi[6] (2.57 km) Existed: 1957-1963-–present Suffolk County Route 63 is a two-lane county highway known as Old East Moriches-Riverhead Road (also Lake Avenue) that leads south from downtown Riverhead, connecting to CR 51 as it makes it way southwest toward Long Island's South Shore. The road is actually a former portion of CR 51, and the designation was given to this section when CR 51 was shifted to the newly-built Center Drive South.
Route description
Though it is only a two-lane road, County Route 63 has a posted 55 mph (89 km/h) speed limit for a majority of its length, an unusual speed limit for a two-lane road on Long Island.[citation needed] The road heads northeast, roughly continuing the track CR 51 while that road curves north onto Center Drive South. It passes the shores of Wildwood Lake and provides access to streets leading to homes along the north and east side of the lake.
The road ends only about a mile and a half from where it started at a traffic circle, which forms the gateway into downtown Riverhead. Here, it links with County Routes 104 and 94, and NYS Route 24, and indirectly to NYS Route 25 via Peconic Avenue.

Location: Bellport-Coram Existed: 1998-–present Suffolk County Route 64 has been designated for Bellport Avenue, and Station Road from the Village of Bellport to Coram-Yaphank (Mill) Road and for Coram-Yaphank Road from Bellport Avenue to NY 112 since 1998. In the 1960s it was believed to be applied to the Dunes Road(not to be confused with Dune Road on Westhampton Beach Island) near Meschutt Park at the Shinnecock Canal, and on October 30, 1975 it was applied to Long Island Avenue (a.k.a.; Patchogue Road) between Suffolk CR 101 and Suffolk CR 21 on the north side of the Long Island Expressway in Yaphank.
County Route 65
County Route 65
Location: Sayville-Patchogue Length: 4.72 mi[6] (7.60 km) Existed: 1937(1965)–present Suffolk County Route 65 is primarily Middle Road from Sayville, New York to Patchogue, New York, where it includes Atlantic Avenue, Weeks Street, River Avenue, and Division Street. In the late-1990's, Middle Road was converted into a one-way street between Main Street and Foster Avenue, forcing Foster Avenue to become part of Suffolk CR 65.
Route description
Suffolk CR 65 begins as Middle Road at Suffolk CR 85(Main Street), although this section is only a one-way street until it reaches the first intersection at Collins Avenue, which is across the street from the NRHP-listed Sayville Congregational Church. The next intersection is Foster Avenue, which is the only two-way access to Montauk Highway. From here Middle Road passes by St. Anne's Episcopal Church, which was recently added to the National Register of Historic Places, and contains the St. Anne's Cemetery in the back. The road then runs through the Sans Soucci Lakes County Park, with a driveway to the NRHP-listed John Ellis Roosevelt Estate on the north side. East of the parkland, the road officially enters the hamlet of Bayport. The first intersection to pass for a major intersection within Bayport is McConnell Avenue. At the intersection with the two-lane divided Edgewater Avenue, CR 65 takes a northeasterly turn and serves as the southern border of Bayport Commons Park. Bayview Avenue is also across from this park, which ends just west of the intersection of Conetquot Road. Snedecore Avenue intersects Middle Road and is one of the few streets along the road to span from Montauk Highway to the Great South Bay, thus making it an important street by local standards.
One of the few areas of commercial zoning along the road is at the blinker-light intersection of Bayport Avenue, where Middle Road moves slightly to the southeast, only to return to the northeast before reaching Gillette Avenue. Shortly after this, CR 65 crosses the Islip-Brookhaven Town Line, where it enters the hamlet of Blue Point. In what will be a common pattern in the Town of Brookhaven, Middle Road makes a sharp left turn to the north, then a right turn at the intersections of Humphrey Road(to the west) and Avery Lane(to the north). CR 65 then crosses a creek that's within a New York State Department of Environmental Conservation preserve area. Once the road exits this preserve, it intersects Lane's End and Nelson Avenue, where it runs between two mansions, one of which is the St. Ursula Retreat Center on the southwest corner of the intersection with Blue Point Avenue. Blue Point Avenue and Middle Road has another set of blinker-lights, partially because it's a four-way stop intersection and partially because it's actually a pair of "T" intersections set close to one another that requires a slight shift to the right for all traffic on Middle Road. After this fiasco, the road passes Bergen Avenue and makes a slight curve to the northeast, only to curve east again and cross the Corey's Creek Bridge, where one can find sites such as the Blue Point Marina, Corey's Creek Park, and a local roadside lunchonette.
Middle Road ends at Atlantic Avenue and Suffolk CR 65 turns north onto Atlantic Avenue, until it reaches the intersection of Weeks Street, and turns back east again. From there, it crosses Tuthills Creek and enters the Village of Patchogue, where it ends at River Avenue, and as Middle Road did with Atlantic Avenue, CR 65 turns north onto River Avenue. Just before River Avenue reaches the at-grade crossing with the Montauk Branch of the Long Island Rail Road, CR 65 turns east one last time at the intersection of Division Avenue, which runs directly along the south side of the tracks. Before crossing the Patchogue River, CR 65 move slightly away from the edge of the tracks, but not far enough away to be out of sight from the tracks. Suffolk County Road 65 ends at Suffolk CR 19(West Avenue). Consequently, CR 19's southern terminus is also at this intersection, but West Avenue continues south as a Patchogue Village street to Patchogue Bay. Likewise, Division Street east of CR 65 is also a village maintained street that continues eastward in front of Patchogue Railroad Station which spans the north side of Division Street between West Avenue and South Ocean Avenue. The road then become Baker Street at Patchogue Village Hall and finally terminates at Rider Avenue.

Location: Dix Hills-Elwood Existed: 1972–present County Route 66 is Deer Park Road East. It serves as a connecting spur between New York State Route 231 and New York State Route 25. Until 1972, it was designated Suffolk CR 35B.
Route description
Suffolk CR 66 begins at the NY 231/County Route 35/County Route 66 wye, which at one time was also intended to include a North Deer Park Avenue Spur connecting to the Babylon-Northport Expressway.[9] The only other "major" intersection between the two termini of CR 66 is a segment of DeForest Road which begins as the off-ramp of Exit 42N of the Northern State Parkway. All other intersections at this point are residential streets. Suffolk CR 66 ends at NY 25 in Elwood, just west of Elwood Road, where the interchange for the former Babylon-Northport Expressway was supposed to exist.

County Route 68
County Route 68
Location: Stony Brook-Setuaket Suffolk County Route 68 is an unsigned two-lane road that runs through historic Stony Brook along Main Street, Christian Avenue, and eventually into Setauket along Ridgeway Avenue, part of which was at one time part of New York State Route 25A.[10] The entire route is also shared with New York State Bicycle Route 25.
Route description
Suffolk CR 68 begins as Main Street at New York State Route 25A near the Stony Brook Museum and Carriage House, as a north-south road. It begins at a segment of NY 25A that briefly runs north and south within Stony Brook before making a sharp right turn towars Setauket, Port Jefferson and points east. A west-to-northbound ramp exists on the northeast corner of the intersection, When CR 68 runs through the Stony Brook Village Center, it turns into an east-west road. At a fork in the road with Hollow Road which heads southeast, CR 68 moves onto Christian Avenue and heads northeast. The rest of CR 68 is surrounded by historic houses, although it also includes the North Shore Montessori School and a local Methodist Church and Cemetery. From there it intersect the appropriatley named Blinker Light Road and Cedar Avenue, which are less than five feet away from each other. Cedar Avenue heads toward the The Stony Brook School and Stony Brook (LIRR station), while CR 68 continues northeast into what is commonly referred to by mapmakers as "Old Stony Brook."
Christian Avenue continues northeast but CR 68 moves southeast onto Bailey Hollow Road, which ends at the intersection of Quaker Path Road, and becomes Ridgeway Avenue. Here, it also leaves Stony Brook and enters Setauket. The next major intersection is North Country Road to the south and Main Street to the north. The former connecting north-to-eastbound ramp which was used by eastbound NY 25A can still be seen on the southeast corner of North Country Road and Ridgeway Avenue.[11] Suffolk CR 68 then climbs a hill before ending at NY 25A just north of the formerly proposed Setauket-Port Jefferson Bypass.
