List of county routes in Suffolk County, New York (76–100)

County Route 76 is Town Line Road along the Islip–Smithtown township line. Until 1968, it was also part of Veterans Memorial Highway from Jericho Turnpike in Commack to Nesconset Highway in Hauppauge. The road shares a short concurrency with NY 111 in Hauppauge. An eastern extension to CR 16 was proposed at one time. The official Suffolk County Department of Public Works listing of county roads still includes this formerly proposed extension. ;Major intersections {{NYint {{NYint {{NYint {{NYint ==County Route 77==

County Route 77 is the north-south road along the west side of Lake Montauk. It begins at an at-grade interchange of Montauk Point State Parkway as West Lake Drive where it intersects two streets that lead to the east side of Montauk Downs State Park, until it reaches CR 70. From here the road runs much closer to Lake Montauk, then intersects with other roads such as Star Island Road to the right, and then East Flamingo Road (former CR 95) to the left. Before the road reaches the Block Island Sound, it intersects with the northern terminus of CR 49. The road then takes a sharp right turn along the sound then loops around in the opposite direction and passes by the ferry port to Block Island, before returning to the intersection with CR 49. ;Major intersections The entire route is in Montauk. {{NYint {{NYint {{NYint {{NYint {{NYint ==County Route 77A==

County Route 77A was the former east wye of CR 77 leading east towards Montauk Point State Parkway. Today it is CR 70. ==County Route 77B==

County Route 77B was the former west wye of CR 77 leading east towards Montauk Point State Parkway. Today it is part of CR 77. ==County Route 78==

County Route 78 is Church Street in the southeastern part of the town of Islip, from NY 27 to Division Avenue in Patchogue. Originally, it was also Veterans Memorial Highway from Nesconset to Sunrise highways until it was extended westward towards Jericho Turnpike in Commack in 1968, replacing part of CR 76. The southeast end of Veterans Memorial Highway bisected Church Street at Sunrise Highway, but only the part of Church Street on the south side of Sunrise Highway was a county road. The north side has never been anything else but a road maintained by the town of Islip. In 1972, Veterans Highway was acquired by the New York State Department of Transportation and designated NY 454, but Church Street remained CR 78. ;Major intersections {{NYint {{NYint {{NYint ==County Route 79==

County Route 79 is a north-south two-lane road, known as the Bridgehampton–Sag Harbor Turnpike. History Known in pre-colonial times as the "Cart Path to Great Meadows," it was replaced by the Bull Head Turnpike Company as a private toll road, called the "Sag Harbor and Bull's Head Turnpike." Construction began in 1834 and the turnpike opened on March 29, 1837. The toll company shut down in 1905, and the toll houses were torn down in 1909. The road was acquired by Suffolk County on November 10, 1948. Major intersections {{NYint ==County Route 79A==

County Route 79A was Main Street in Sag Harbor. It was established on October 23, 1952 and merged into CR 79 after the 1960s. ==County Route 80==

County Route 80 is the county route designation used for Montauk Highway (also labeled as Main Street, East Main Street and West Main Street) between East Patchogue and Shinnecock Hills. ==County Route 80 Truck==

Two Truck routes of County Route 80 exist in two locations. The first is in Moriches on Old Neck Road and Wilcox Avenue leading trucks around a low bridge beneath the Long Island Rail Road Montauk Branch. The second includes North Bay Avenue in Eastport, New York, which leads truck drivers from another low bridge for the same line within the community, then turns right overlapping Old Country Road into Speonk, where it turns south on North Phillips Avenue and ends at Montauk Highway just south of the Speonk (LIRR station). The latter of these was originally designated as New York State Route 27 Truck, when New York State Route 27 was part of Montauk Highway between Exits 61 and 65 on Sunrise Highway. ==County Route 81==

County Route 81 is the shortest county road in Suffolk County. Known as Wharf Street, the road consists entirely of a segment of the former Sag Harbor Branch of the Long Island Rail Road. It runs from an intersection with NY 114 (Bay Street) to the end of the pier on Gardiners Bay. The Sag Harbor Branch was abandoned in 1940, and the road was established in 1949. It is not signed. ==County Route 82==

County Route 82 is the designation for Higbie Lane from its starting point to Udall Road, and for most of Udall Road. It was named for the Richard Udall family who had an estate on South Country Road (now Montauk Highway). Higbie Lane starts as a two lane divided highway with a U-turn at NY 27A (Montauk Highway), between the historic La Grange Inn and the West Islip Public Library, and instantly becomes a two-lane undivided highway with a center-left-turn lane. Heading north, CR 82 intersect CR 50, immediately followed by an at-grade crossing of the Long Island Rail Road Montauk Branch near the Babylon Yard for the Babylon station, and then serves the west end of West Islip Boulevard, which runs along the north side of the tracks and becomes Orinoco Drive. The route shifts to the northeast at a former wye onto Udall's Road, and Higbie Lane becomes a town of Islip maintained road. As Udall Road, CR 82 passes through another semi-residential area and then runs underneath the underpass of NY 27 between exits 40 and 41. The next moderate intersection is with Hunter Avenue and Muncey Road. Together these roads span from CR 34 to CR 57 between Sunrise Highway and the Southern State Parkway. CR 82 runs over the Southern State Parkway, but has no access to the parkway. The route finally ends at CR 57, however while CR 82 ends there, Udall Road continues as a town of Islip road towards Howell's Road, which leads to Corbin Avenue and eventually to the Deer Park station. ;Major intersections The entire route is in West Islip. {{NYint {{NYint {{NYint {{NYint ==County Route 83==

County Route 83 is a major county road within the town of Brookhaven. It runs north and south from NY 27 (Sunrise Highway) at exit 52A in North Patchogue to NY 25A in Mount Sinai. ==County Route 83A==

County Route 83A was a formerly proposed spur that was intended to run from an unbuilt segment of CR 83 to Cedar Beach in Mount Sinai. It was supposed to run northwest, parallel to Pipe Stave Hollow Road, and end at Cedar Beach Town Park. ==County Route 84==

County Route 84 was a road that looped around northern Mattituck. This road included a bridge over Mattituck Creek that no longer exists. It began as Cox Neck Road on Sound Avenue, just west of the western terminus of what is today CR 48 (Middle Road). It had only one street even remotely resembling a major intersection, Bergen Avenue. The road takes a sharp right turn and heads east where it used to cross over Mattituck Creek. On the east side of Mattituck Creek, the road was Mill Neck Road. As Mill Neck Road became Oregon Avenue in Oregon, CR 84 turned south on Mill Road, where it crossed former CR 27A then CR 48 and headed back to NY 25 near East Mattituck. ==County Route 85==

County Route 85 is Montauk Highway between the Oakdale Merge and Patchogue. ==County Route 86==

County Route 86 runs from NY 25 and Dix Hills Road as Broadway–Greenlawn and Centerport Road into Little Neck Road in Centerport. ;Route description CR 86 begins at the intersection of NY 25 and Dix Hills Road and at first runs northeast to southwest and immediately curves to a more northerly direction before the intersection of CR 35. Just northeast of Lekamb Avenue, the road straightens out, briefly moving direct north. This change is short-lived as it heads back northeast at Lantern Street. After passing two T-intersections connecting CR 86 to separate parts of Delamere Street, the road passes along the west side of a former apple grove that is now part of the Manor Plains Nature Park, a preserved land that is bisected by an L-shaped residential street which ends at Manor Road, a road which runs parallel to CR 86. Residences do turn up again on the east side north of the intersection with Leigh Street on the west side. Parkland turns up again on the same side just south of the opposite side of the intersection with Depew Street, only to end again at a local dog kennel. What passes for a major intersection at this point is Little Plains Road, which is also part of New York State Bicycle Route 25A. The heart of Greenlawn is reached at the intersection of CR 9, the northwest corner of which contains Greenlawn Park, a local baseball field that runs along. The park is located along the west side of Broadway, east side of Cuba Hill Road, and south side of CR 11 (Pulaski Road), which it intersects almost instantly. Further into town, CR 86 passes an at-grade railroad crossing of the Port Jefferson Branch of the Long Island Rail Road close to Greenlawn Railroad Station. After passing the Harborfields Public Library, the road becomes much more residential. It curves to the left as it moves down the hills approaching the north shore, then makes a sharp curve to the northeast before the intersection with NY 25A at the Suydam Homestead. ;History The road was once planned to be replaced by a four-lane divided highway known as CR 107, which would've extended it down towards Belmont Lake State Park and West Babylon. ;Major intersections {{NYint {{NYint {{NYint {{NYint {{NYint {{NYint ==County Route 87==

County Route 87 is an unsigned county route on two-lane Edgewood Ave, which may have been part of NY 25A. The road runs southwest to northeast north of the Port Jefferson Branch of the Long Island Rail Road, and is inventoried as a west-to-east road. ;Route description The road begins at the NY 25–NY 25A overlap in western Smithtown, at the north end of Brooksite Drive. Besides running north of the LIRR Port Jefferson Line, it also runs south of the Nissequogue River until it reaches Nissequogue River Road. Prior to this point, the road curves at a more easterly direction before the intersection of Landing Avenue. After passing by some surviving farmland as well as a middle school, the road enters the southernmost portion of the village of Head of the Harbor where it intersects Fifty Acre Road before ending at NY 25A in St. James. ;Major intersections {{NYint {{NYint ==County Route 88==

County Route 88 is a two-lane highway known as Speonk–Riverhead Road, however the road doesn't go as far north as Riverhead as it originally did. The county describes the distance as being "3.8+ miles." The road terminates at the northeast corner of the Eastern Campus of Suffolk County Community College. ;Route description CR 88 begins at CR 71 (Old Country Road) in Speonk, just east of Phillips Avenue, which serves as both a truck detour for County Route 80 (Suffolk County, New York), and as the road to Speonk's Long Island Railroad station. It was once planned to cross under the Port Jefferson–Westhampton Beach Highway. Most of the road continues through a section of the Long Island Central Pine Barrens, which feature the indigenous dwarf pine. This area fell victim to a widespread wildfire that burned a significant portion of the core of the Pine Barrens in 1995. Halfway along its existence, the road serves as an overpass for NY 27, but does not have an interchange with it . After the road runs along the SCC Eastern Campus, CR 88 ends at CR 51 (East Moriches–Riverhead Road) in Northampton. The former section that actually got close to Riverhead is now only a dirt trail whose name only exists on paper. ;Major intersections {{NYint {{NYint {{NYint ==County Route 89==

County Route 89, better known as Dune Road, spans the Southampton segment of Fire Island from the east side of Cupsogue Beach County Park at Moriches Inlet to the Shinnecock Inlet. It begins east of Moriches Inlet at Cupsogue Beach County Park, and crosses the Brookhaven–Southampton town line in West Hampton Dunes, which is almost entirely line with residential beach houses and the occasional private roads, with the exception of Pike's Beach town Park. Even after leaving the village, CR 89 continues to maintain these characteristics, but occasionally features random beach clubs, recreational areas, and another town of Westhampton Beach named Lashley Beach Moriches Bay ends on the north side of the street, and flows into Moneybogue Bay, which runs under the Jessup Lane Bridge in Westhampton Beach across from the Swordfish Beach Club. This is the first connection to the rest of Long Island. In between the segment along Moneybogue Bay, the residential beach houses continue to line the road, but more of them are surrounded by shrubs and small trees. The bay flows into the much narrower Quantuck Creek, which runs under Beach Lane Bridge which is also in Westhampton Beach across from Rogers Beach. The pattern of beach houses blocked by greenery continues, but primarily along the Atlantic Ocean side of the road. When Quantuck Creek flows into Quantuck Bay, the houses are more abundant. Here the road also passes by the Quantuck Beach Club, which despite being located on the south side of the road, has a parking lot on the north side. The road enters the village of Quogue just before the intersection of Water's Edge Road. The next intersection is Watersedge Drive, which ends where Quantuck Bay flows into the Quogue Canal. Within this area, CR 89 passes the Surf Beach Club of Quogue, and then encounters its only major intersection, a wye intersection at the Post Lane Bridge which crosses the canal is the only access to the rest of Long Island in Quogue. Shortly after the bridge, the road passes the Quogue Beach Club. While the south side of the road continues the pattern of private beach houses, most of the land on the north side of the road is undeveloped marshland, especially as Quogue Canal opens up into Shinnecock Bay. This pattern continues east of the village line. East of Dockers Waterside Restaurant, the north side of the road contains marshland that is so low, that satellite views make it appear as if the road runs along the bay itself. At the intersection of Dolphin Lane, the northern portion of which terminates just out of reach of Sedge Island, CR 89 serves as the terminus of another unpaved and unnamed road that would provide easier access to that island. This is soon overshadowed by a clister of residential streets on the south side, known as A Road, Road C, and Road D. A few Road B's can be found within that cluster, but none intersect with Dune Road. Northside marshland becomes more solid on another unnamed dirt road a block west of Triton Lane. East of here, the Shinnecock Bay resumes its domination of the north side of the road, with only a brief interruption of land. However, sparse north side residences begin turning up again across the street from the Hampton Ocean Resort, and soon after intersecting Mermaid Lane, Neptune Beach Club. Further east along the bay the road enters Shinnecock Inlet County Park. The few intersections in this area are K Road and later Road K. The next intersection, however is for the Ponquogue Bridge in Ponquogue, which provides the last access point to the rest of Long Island. Parallel to this is an intersection with Beach Road, which leads to the former Ponquogue Bridge, now serving as a fishing pier. Both the former and current bridges are across from Ponquogue Beach. One more intersection with Road I can be found east of there before the road prepares to conclude near a series of restaurants and marinas on the north side. The last intersection is Road H, which is a dead end street at both ends, and the road ends at Shinnecock Inlet at a parking lot along the inlet with a light tower on the south end. ;Major intersections {{NYint {{NYint {{NYint {{NYint {{NYint ==County Route 90==

County Route 90 is a pair of unsigned county roads (Furrows Road and Peconic Avenue) that were planned as a Central Suffolk Highway, the second part of a proposed reconnection of the two segments of NY 24. ;History Suffolk County Department of Public Works added CR 90 to the system on October 10, 1966, and officially describes the road as follows; Beginning at C.R. 93, Lakeland Avenue–Ocean Avenue in the town of Islip, about 600 feet south of the Long Island Railroad(sic); thence easterly in general parallel to the Long Island Railroad to the vicinity of Knickerbocker Avenue; thence to Furrows Road in the vicinity of Lincoln Avenue; thence easterly along or in the vicinity of Barrett's Avenue to C.R. 83, Patchogue–Mt. Sinai Road(sic) at or in the vicinity of Peconic Avenue to C.R. 16, Horseblock Road(sic), a distance of 4.3 miles in the town of Islip, and 4.2 miles in the town of Brookhaven, a total distance of 8.5 miles. Road maps published between the 1960s and 1980s show a proposed road labeled CR 90 between Moriches–Middle Island Road at North Street and CR 111 at Hot Water Street, the very location where other maps indicate that the proposed western extension of CR 105 was intended to terminate. CR 90 was neither built according to its official description, nor to its ultimate proposal. The only segments that originally existed when the route was designated are Furrows Road between Lincoln Avenue and Waverly Avenue, and Peconic Avenue between CR 83 and CR 16. Barrett's Avenue is a town of Brookhaven residential dead end street extending east of Waverly Avenue, however it does provide a connection to CR 83 via Old Fish Road, a segment of the former Fish Thicket Road which is a local road dating back to the American Revolution. Segments that could've been part of the proposed CR 90 include a four-lane dead end highway near the Suffolk County Police Department headquarters on CR 21 in Yaphank built during the 1970s, and a segment of Railroad Avenue South between CR 29 and Knickerbocker Avenue built during the 1980s as part of the major reconstruction of Ronkonkoma Railroad Station. ;Major intersections {{NYint {{NYint {{NYint {{NYint {{NYint {{jctgap {{NYint {{NYint {{NYint {{NYint ==County Route 91==
