County routes in Suffolk County, New York, are maintained by the Suffolk County Department of Public Works and signed with the Manual on Uniform Traffic Control Devices-standard yellow-on-blue pentagon route marker. The designations do not follow any fixed pattern. Routes 51 to 75 are listed below.

County Route 51
Location	East Moriches–Riverside
Length	8.46 mi[1] (13.62 km)
Existed	1933–present

County Route 51 is a major road running southwest-to-northeast from CR 80 to NY 24 and CR 94 in Riverside.

Route description

The road begins at CR 80 (Montauk Highway) just east of the eastern terminus of CR 98 (Frowein Road). The route 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 NY 27 (Sunrise Highway), CR 51 becomes a four-lane expressway and is one of the roads served by the incomplete exit 61. The other one is CR 55, which served as part of NY 27 until Sunrise Highway was extended east of the interchange. CR 51 became the northern terminus of CR 55 in the 1980s.

The road continues northeast through the hills of the Long Island Pine Barrens. Soon thereafter, CR 51 reaches the intersection of Speonk–Riverhead Road (former CR 88), which leads to the Suffolk County Community College eastern campus. Northeast of that point, the road literally starts to go downhill.

At Wildwood Lake, there is an incomplete at-grade interchange with CR 63 (Lake Avenue), which used to be part of East Moriches–Riverhead Road. 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 CR 103 (Cedar Swamp Road), then enters a series of Suffolk County Government buildings, where it finally terminates at an at-grade intersection at NY 24 and CR 94 in Riverside.

County Route 53
Location	Bay Shore
Existed	c. 1967

County Route 53 was Clinton Avenue in Bay Shore. Today it serves as a southbound only suffixed route of CR 13, known as CR 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
Location	Calverton–Wading River
Length	1.02 mi[3] (1.64 km)
Existed	1935[3]–present

County Route 54 is mainly Hulse Landing Road, a two-lane road that runs north and south Wading River.

The route begins at Sound Avenue in Wading River, with Hulse Landing Road continuing south from the intersection. The road passes by a Wading River Fire Department depot and several businesses within the housing it passes through.

Though Hulse Landing Road heads straight north toward Old North Country Road along the western border of Wildwood State Park, CR 54 curves northeast into Wildwood Road, the southern entrance of the park.

Although there was signage at the southern terminus of Hulse Landing road at NY 25A, the portion of CR 54 between Sound Avenue and 25A has been decommissioned.

The road formerly began at NY 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 CR 54 at an interchange. The Nugent Drive Extension was intended to serve as the relocated NY 25A. Sound Avenue was to be transformed into a dead end street west of former CR 54. Today, the land intended to be used for the road is now part of a housing development.

The portion of CR 54 north of Sound Avenue was designated as NY 352 from c. 1931^[4][5] to c. 1938.^[6][7]

Major intersections

The entire route is in Wading River.

County Route 55
Location	Eastport
Length	1.0 mi[9] (1.6 km)
Existed	1935–present

County Route 55 is a short county road in Suffolk County, New York, located in and around Eastport known as Eastport–Manor Road, and sometimes Eastport–Manorville Road. It runs north and south from CR 80 (Montauk Highway, formerly NY 27A) to CR 51 north of Eastport.

History

As the name implies, the road originally went from Manorville to Eastport, and was acquired by the Suffolk County Department of Public Works in 1935. The section between Montauk Highway and 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 CR 55 until it reached Montauk Highway, and continued eastward toward Montauk.^[10]

Construction of the vast and complex exit 61 interchange forced the realignment of CR 55, as well as Head of the Neck Road.^[11] When 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 CR 55 north of CR 111 leading to the Grumman Calverton Airport. An interchange with the expressway was also supposed to have been built.^[12] Neither of these proposals were ever accepted.

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	Yaphank–Shirley
Length	2.20 mi[3][14] (3.54 km)
Existed	1960–present

County Route 56 is a bi-directional frontage road along NY 27 known as Victory Avenue. It stretches from CR 16 between Sunrise Highway and CR 21 and ends at William Floyd Parkway, however Victory Avenue extends east of the CR 56 designation. At one time, it also included Horseblock Road east of Waverly Avenue in Farmingville.

CR 56 provides the entrance to Southaven 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	4.8 mi[15] (7.7 km)
Existed	1935–present

County Route 57 runs mostly east and west from NY 231 in Deer Park to NY 27A in downtown Bay Shore. It includes Bay Shore Road, Howell's Road, and Third Avenue.

Route description

No sooner does CR 57 start at NY 231 in a sharp southeasterly direction, does it encounter Carl’s Path and CR 4 (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. CR 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 and Robert Moses Causeway. Originally it crossed Bay Shore Road, then moved along the south side and intersected with Bay Shore Road again along with Muncey Road.

At the intersection of Muncey Road, 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 NY 27 (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 CR 13. CR 57 turns south onto Third Avenue, where it crosses CR 50, and finally terminates at NY 27A in downtown Bay Shore.

County Route 57A
Location	Bay Shore
Existed	1935–1967

County Route 57A was the former designation for Third Avenue south of Howell's Road towards NY 27A in Bay Shore. It became part of CR 57.

County Route 57B
Location	Bay Shore–North Bay Shore
Existed	1935–1967

County Route 57B was the former designation for Third Avenue north of Howell's Road to either Sunrise Highway eastbound service road, or possibly as far north as CR 13 and Brook Avenue. The road was decommissioned and is now maintained by the town of Islip.

County Route 58
Location	Calverton–Riverhead
Length	4.4 mi[16] (7.1 km)
Existed	1936–present

County Route 58, locally known as Old Country Road, 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.^[17]

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 turnarounds in the median. This was built in conjunction with the interchanges with the Long Island Expressway 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 six 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 northeast of the town of Riverhead.

County Route 60
Location	Noyack–North Haven
Length	1.7 mi[20] (2.7 km)
Existed	1970s–present

County Route 60 is a county road formerly known as 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 with North Haven.

Noyack–Long Beach Road was previously known as Long and Short Beach Highway. CR 60 begins at an at-grade interchange with CR 38 in Noyack between Noyac 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, where Noyack–Long Beach Road becomes Short Beach Road at Third Street. CR 60 ends at a traffic circle at NY 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
Length	3.5 mi[21] (5.6 km)
Existed	1975–present

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

CR 61 begins at CR 19, 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 northeasterly turn and straightens out along the Islip–Brookhaven town line. CR 61 is the last interchange along Woodside Avenue (CR 99) before its western terminus at Patchogue–Holbrook Road. Access is only available from Woodside Avenue; however this interchange also includes an 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.

The last intersection within range of the town of Islip is for Furrow Roads (eastern terminus of 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 the Holtsville train 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 CR 97 (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 route shields, CR 61 ends unceremoniously at CR 16 (Horseblock Road), east of where CR 16 moves from the eastern terminus of Portion Road onto Horseblock Road. North of Horseblock 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.

County Route 62
Location	Hampton Bays
Length	0.9 mi[22] (1,400 m)
Existed	1936–present

County Route 62 can be found on the west side of the Shinnecock Canal along Newtown Road north of Montauk Highway and partially into Sunset Avenue at the Shinnecock County Marina. The entire route is in the hamlet of Hampton Bays.

Route description

CR 62 begins as Newtown Road at a divided section of Montauk Highway (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 have 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-foot-7-inch (3.53 m) 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 CR 39B on the east side of the canal, 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, 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

Length	1.6 mi[23] (2.6 km)
Existed	1963–present

County Route 63 is a two-lane north–south highway that connects Riverside and NY 24 with Riverhead and NY 25. It is named Lake Avenue (formerly Old East Moriches–Riverhead Road) south of a roundabout with NY 24 and Peconic Avenue north of it. It has a posted 55 mph (89 km/h) speed limit for a majority of its length. The road begins at an intersection with CR 51 and heads northeast, roughly continuing the track of 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 then intersects a roundabout, which forms the gateway into downtown Riverhead. Here, it links with CR 104, CR 94, and NY 24. The road then continues a short ways north via Peconic Avenue to terminate at an intersection with NY 25. The road is a former portion of CR 51, and the CR 63 designation was given to this section when CR 51 was shifted to the newly built Center Drive South.

County Route 64 is the unsigned designation 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 applied to Dunes Road–not to be confused with CR 89 in Westhampton Beach–near Meschutt Park at the Shinnecock Canal. On October 30, 1975 it was applied to Long Island Avenue (also known as Patchogue Road) between CR 101 and CR 21 on the north side of the Long Island Expressway in Yaphank.

County Route 65
Location	Sayville–Patchogue
Length	4.8 mi[25] (7.7 km)
Existed	1937–present

County Route 65 is primarily Middle Road from Sayville to Patchogue, where it includes Atlantic Avenue, Weeks Street, River Avenue, and Division Street. In the late 1990s, Middle Road was converted into a one-way street between Main Street and Foster Avenue, forcing Foster Avenue to become part of CR 65.

Route description

CR 65 begins as Middle Road at 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 is a four-way stop intersection and partially because it is 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 luncheonette.

Middle Road ends at Atlantic Avenue and 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. CR 65 ends at 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.

Route description

CR 66 begins at a wye intersection with CR 35, which at one time was also intended to include a North Deer Park Avenue Spur connecting to the Babylon–Northport Expressway.^[10] 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. 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 67A
Location	Melville–Half Hollow Hills
Existed	1960s

County Route 67A was originally Half Hollow Hills Road from Pinelawn Road to Motor Parkway, that served as an extension of CR 67. It was eventually decommissioned and merged into CR 67.

County Route 68
Location	Stony Brook–Setuaket
Length	3.0 mi[28] (4.8 km)

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 NY 25A.^[29] The entire route is also shared with New York State Bicycle Route 25.^[30]

Route description

CR 68 begins as Main Street at NY 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 towards 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 intersects the appropriately named Blinker Light Road and Cedar Street, which are less than five feet away from each other. Cedar Street heads toward The Stony Brook School and Stony Brook's train 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.^[31] CR 68 then climbs a hill before ending at NY 25A just north of the formerly proposed Setauket–Port Jefferson Bypass.
