Greenway (landscape) in the context of "Manhattan Waterfront Greenway"

A green belt or greenbelt is a policy, and land-use zone designation used in land-use planning to retain areas of largely undeveloped, wild, or agricultural land surrounding or neighboring urban areas. Similar concepts are greenways or green wedges, which have a linear character and may run through an urban area instead of around it. In essence, a green belt is an invisible line designating a border around a certain area, preventing development of the area and allowing wildlife to return and be established.

The more general term in the United States is green space or greenspace, which may be a very small area such as a park.

The Finger Plan (Danish: Fingerplanen) is an urban plan from 1947 which provides a strategy for the development of the Copenhagen metropolitan area, Denmark. According to the plan, Copenhagen is to develop along five 'fingers', centred on S-train commuter rail lines, which extend from the 'palm', that is the dense urban fabric of central Copenhagen. In between the fingers, green "wedges" are intended to provide land for agriculture and recreational purposes.

By the definition in the Finger Plan the metropolitan area has a population of 2,036,717 (as of 1 January 2017) and an area of 3,030 km (1,170 sq mi) over 34 municipalities.

White Oak Bayou is a slow-moving river in Houston, Texas. A major tributary of the city's principal waterway, Buffalo Bayou, White Oak originates near the intersection of Texas State Highway 6 and U.S. Highway 290 (the Northwest Freeway) and meanders southeast for 25 miles (40 km) until it joins Buffalo Bayou in Downtown. The river serves as a greenway which connects Downtown to the Houston Heights, Oak Forest, Garden Oaks, and Inwood Forest.

A large majority of White Oak Bayou's route travels through highly developed areas. The river's 111-square-mile (290 km) watershed contains a population of over 430,000.

Salt (Catalan pronunciation: [ˈsal]) is a municipality in the comarca of the Gironès in Catalonia. It is situated on the right bank of the Ter next to Girona, with which it was merged from 1974 to 1984. The A-7 autopista and N-141 road pass through the municipality.

From 1895, Salt was the temporary Girona terminus of the narrow gauge Olot–Girona railway, until the short section to Girona railway station was opened in 1898. Initially the line ran only as far as Amer, but it was extended to Les Planes d'Hostoles in 1900, Sant Feliu de Pallerols in 1902 and Olot in 1911. The line closed in 1969 and has since been converted into a greenway.

The Boise River Greenbelt is a recreational and alternate transportation trail along the banks of the Boise River through Boise, Idaho, United States. The Boise Greenbelt is more of a greenway than a green belt since its character is linear. It extends more than 20 miles (32 km) beginning at Lucky Peak Dam in the east to a short distance beyond Eagle Road (Idaho State Highway 55) in the west in Eagle, Idaho. Taking into account both sides of the river and other parallel trails and spurs, the total Greenbelt trail system measures more than 30 miles (48 km).

The High Line is a 1.45-mile-long (2.33 km) elevated linear park, greenway, and rail trail created on a former New York Central Railroad spur on the West Side of Manhattan in New York City. The High Line's design is a collaboration between James Corner Field Operations, Diller Scofidio + Renfro, and Piet Oudolf. The abandoned spur has been redesigned as a "living system" drawing from multiple disciplines which include landscape architecture, urban design, and ecology. The High Line was inspired by the 4.7 km (2.9 mi) long Coulée verte (tree-lined walkway), another elevated park in Paris completed in 1993.

The park is built on an abandoned, southern viaduct section of the New York Central Railroad's West Side Line. Originating in the Meatpacking District, the park runs from Gansevoort Street—three blocks below 14th Street—through Chelsea to the northern edge of the West Side Yard on 34th Street near the Javits Center. The West Side Line formerly extended south to a railroad terminal at Spring Street, just north of Canal Street, and north to 35th Street at the site of the Javits Center. Due to a decline in rail traffic along the rest of the viaduct, it was effectively abandoned in 1980 when the construction of the Javits Center required the demolition of the viaduct's northernmost portion. The southern portion of the viaduct was demolished in segments during the late 20th century.

A linear park is a type of park that is significantly longer than it is wide. These linear parks are strips of public land running along canals, rivers, streams, defensive walls, electrical lines, or highways and shorelines. Examples of linear parks include everything from wildlife corridors to riverways to trails, capturing the broadest sense of the word. Other examples include rail trails ("rails to trails"), which are disused railroad beds converted for recreational use by removing existing structures. Commonly, these linear parks result from the public and private sectors acting on the dense urban need for open green space. Linear parks stretch through urban areas, coming through as a solution for the lack of space and need for urban greenery. They also effectively connect different neighborhoods in dense urban areas as a result, and create places that are ideal for activities such as jogging or walking. Linear parks may also be categorized as greenways. In Australia, a linear park along the coast is known as a foreshoreway. When being designed, linear parks appear unique as they are planned around the public's opinion of how the space will affect them.

A rail trail or railway walk is a shared-use path on a railway right of way. Rail trails are typically constructed after a railway has been abandoned and the track has been removed but may also share the rail corridor with active railways, light rail, or streetcars (rails with trails), or with disused track. As shared-use paths, rail trails are primarily for non-motorized traffic including pedestrians, bicycles, horseback riders, skaters, and cross-country skiers, although snowmobiles and ATVs may be allowed. The characteristics of abandoned railways—gentle grades, well-engineered rights of way and structures (bridges and tunnels), and passage through historical areas—lend themselves to rail trails and account for their popularity. Many rail trails are long-distance trails, while some shorter rail trails are known as greenways or linear parks.
