A county highway is a road in the United States and in the Canadian province of Ontario that is designated and/or maintained by the county highway department. Route numbering can be determined by each county alone, by mutual agreement among counties, or by a statewide pattern.
New York State Route 3 (NY 3) is a major east–west state highway in New York, in the United States, that connects central New York to the North Country region near the Canada–US border via Adirondack Park. The route extends for 245.88 miles (395.71 km) between its western terminus at an intersection with NY 104A in the Cayuga County town of Sterling and its eastern terminus at a junction with U.S. Route 9 (US 9) in the Clinton County city of Plattsburgh. NY 3 traverses eight counties and is a lakeside roadway from Mexico to Sackets Harbor, a mountainous route in Adirondack Park, and an urban arterial in Fulton, Watertown, and Plattsburgh.
New York State Route 324 (NY 324) is an east–west state highway located in the western portion of New York in the United States. Officially, NY 324 begins at NY 384 in Niagara Falls and overlaps Interstate 190 south to Grand Island, where it separates from I-190 and continues southward as Grand Island Boulevard. As signed, however, NY 324 begins at the southern end of the official overlap and is contained entirely within Erie County. At the southern edge of Grand Island, NY 324 joins I-190 to cross over to the mainland, where it runs due east across three towns before reaching its eastern end at a junction with NY 5 in the town of Clarence.
New York State Route 18 (NY 18) is an east–west state highway in western New York in the United States. It runs parallel to the south shore of Lake Ontario for most of its length between Niagara County and Monroe County. NY 18, which also passes through Orleans County, acts as a northerly alternate to NY 104, another east–west route that parallels NY 18 to the south on Ridge Road. The western terminus of NY 18 is at a complex grade-separated interchange with NY 104 outside the village of Lewiston. Its eastern terminus is at a junction with NY 104 in an area of Rochester known as Eastman Business Park.
New York State Route 93 (NY 93) is a 43.08-mile (69.33 km) state highway in western New York in the United States. The route begins at an intersection with NY 18F in the village of Youngstown and runs in a general northwest–southeast direction across Niagara and Erie counties to its east end at an intersection with NY 5 in the town of Newstead, just south of the village of Akron. NY 93 serves as a connector between several major arterials, including NY 104 in Cambria, NY 31 just west of the city of Lockport, and NY 78 south of the city.
New York State Route 18F (NY 18F) is a 9.80-mile (15.77 km) long state highway in northwestern Niagara County, New York, in the United States. The southern terminus of the route is at an interchange with NY 104 and the Niagara Scenic Parkway just east of the village of Lewiston. The northern terminus is at an intersection with NY 18 near Four Mile Creek State Park in Porter. NY 18F parallels NY 18 for most of its alignment, taking a more westerly course than its parent. NY 18F is the only remaining suffixed route of NY 18.
New York State Route 179 (NY 179) is a short 4.40-mile (7.08 km) long state highway located south of Buffalo in Erie County, New York, in the United States. It is a four-lane divided highway for most of its length. It is known as Mile Strip Road. A small section between U.S. Route 62 (US 62) and NY 5 in Blasdell, however, is an expressway known as the Mile Strip Expressway. It connects to two major freeways, the New York State Thruway and the Southern Expressway (US 219), by way of interchanges. It serves as a connector road between them and three other major routes, NY 5, US 62, and US 20. Thus it is very busy not only at rush hours, but also after Buffalo Bills' home football games due to its proximity to Highmark Stadium.
New York State Route 31E (NY 31E) is a 5.29-mile (8.51 km) state highway located in western New York in the United States. It serves as a northerly alternate route of NY 31 between the village of Middleport in eastern Niagara County and the nearby village of Medina in Orleans County. NY 31E connects to NY 31 at each end by way of a short overlap with NY 271 in Middleport. Most of NY 31E parallels the Erie Canal, and parts of the route run adjacent to the waterway. Outside of the two villages at each end, NY 31E traverses mostly rural areas of the towns of Royalton and Ridgeway.
New York State Route 380 (NY 380) was a 23-mile (37 km) north–south state highway in Chautauqua County, New York, in the United States. The southern terminus of the route was at an intersection with NY 60 in the town of Gerry. Its northern terminus was at a junction with NY 5 north of the village of Brocton in the town of Portland. In actuality, most of NY 380 was maintained by Chautauqua County; the only part that was maintained by the New York State Department of Transportation was from NY 424 in Stockton to the west end of its overlap with U.S. Route 20 (US 20) in Brocton.
In the U.S. state of New York, county routes exist in all 62 counties except those in the five boroughs of New York City. Most are maintained locally by county highway departments. County route designations are assigned at the county level; as a result, routes often change numbers as they cross from one county to the next due to the lack of a statewide numbering system and lack of coordination between counties. Some exceptions exist, such as County Route 36 (CR 36) in Ontario County and CR 36A in Livingston County. The assignment of routes by individual counties also results in varying system density and numbering and signage practices between the state's counties.
Ridge Road is a 121.5-mile (195.5 km) east–west road that traverses four counties in Upstate New York in the United States. The road begins adjacent to the Niagara River at an intersection with Water Street in the village of Lewiston, Niagara County, and passes through several towns, villages, and the city of Rochester before arriving at its eastern terminus at a junction with New York State Route 370 (NY 370) southwest of Red Creek, Wayne County. It is named for the rise atop which the road was built, a mound of sand and gravel that was formed when it was the shoreline of ancient Glacial Lake Iroquois. The ridge is often confused with the nearby Niagara Escarpment, which is much taller, geologic in origin, and lies a few miles to the south.
The New York State Department of Transportation (NYSDOT) is responsible for the establishment and classification of a state highway network which includes Interstate Highways, U.S. Highways, and state routes. U.S. and Interstate Highways are classified as state routes in New York; however, a letter is suffixed to the number of the route. As a result, there is apparent duplication between U.S. Routes, Interstate Highways and state routes.
New York State Route 319 (NY 319) was a state highway in Chenango County, New York, in the United States. It was 5.47 miles (8.80 km) long and connected the hamlet of Preston to the nearby city of Norwich. The route began in the hamlet at an intersection with three county-maintained highways and proceeded eastward through the town of Preston to downtown Norwich, where it terminated at an intersection with NY 12.
