Walkway in the context of "Toronto, Ontario"

A road surface (British English) or pavement (North American English) is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway. In the past, gravel road surfaces, macadam, hoggin, cobblestone and granite setts were extensively used, but these have mostly been replaced by asphalt or concrete laid on a compacted base course. Asphalt mixtures have been used in pavement construction since the beginning of the 20th century and are of two types: metalled (hard-surfaced) and unmetalled roads. Metalled roadways are made to sustain vehicular load and so are usually made on frequently used roads. Unmetalled roads, also known as gravel roads or dirt roads, are rough and can sustain less weight. Road surfaces are frequently marked to guide traffic.

Today, permeable paving methods are beginning to be used for low-impact roadways and walkways to prevent flooding. Pavements are crucial to countries such as United States and Canada, which heavily depend on road transportation. Therefore, research projects such as Long-Term Pavement Performance have been launched to optimize the life cycle of different road surfaces.

A boardwalk (alternatively board walk, boarded path, or promenade) is an elevated footpath, walkway, or causeway typically built with wooden planks, which functions as a type of low water bridge or small viaduct that enables pedestrians to better cross wet, muddy or marshy lands. Such timber trackways have existed since at least Neolithic times.

In many seaside resort locations, boardwalks along the beach provide access to shops, hotels, and tourist attractions. The Jersey Shore in the United States is especially noted for its abundance of boardwalks.

In urban planning and urban design, a city block, residential block, urban block, houseblock, or simply block is the smallest group of buildings that is surrounded by streets. City blocks are the space for buildings within the street pattern of a city, and form the basic unit of a city's urban fabric. City blocks may be subdivided into any number of smaller land lots usually in private ownership, though in some cases, it may be other forms of tenure. City blocks are usually built-up to varying degrees and thus form the physical containers, or "streetwalls," of public spaces. Most cities are composed of a greater or lesser variety of sizes and shapes of an urban block. For example, many pre-industrial cores of cities in Europe, Asia, and the Middle East tend to have irregularly shaped street patterns and urban blocks, while cities based on grids have much more regular arrangements.

By extension, the word "block" is an important informal unit of length equal to the distance between two streets of a street grid.

Hardscape is hard landscape materials in the built environment structures that are incorporated into a landscape. This can include paved areas, driveways, retaining walls, sleeper walls, stairs, walkways, and any other landscaping made up of hard wearing materials such as wood, stone, and concrete, as opposed to softscape, the horticultural elements of a landscape.

Hard landscaping involves projects that cover the entirety of the yard and that are necessary before soft landscaping features come into play. Hard landscaping alters the foundation of the yard, the "bricks and mortar" so to speak; only when this is completed can the landscaper begin to focus on the softscape features of the yard, such as lawn, floral plantings, trees and shrubs. One key feature of hard landscaping has to do with the absorption of water – something that is of great importance given the climate. Hard landscaping ensures that worrying about water after heavy rain or snowfall is not an issue. The right water absorption and irrigation system installed through hard landscaping, coupled with hard materials that safely move water away from the property can ensure that soil movement is never a problem and that the yard stays a drier, enjoyable living space, rather than a wet and muddy bog. There are soft landscaping options that can help to achieve this, but the bulk of this is achieved through hard landscaping.

A pier is a raised structure that rises above a body of water and usually juts out from its shore, typically supported by piles or pillars, and provides above-water access to offshore areas. Frequent pier uses include fishing, boat docking and access for both passengers and cargo, and oceanside recreation. Bridges, buildings, and walkways may all be supported by architectural piers. Their open structure allows tides and currents to flow relatively unhindered, whereas the more solid foundations of a quay or the closely spaced piles of a wharf can act as a breakwater, and are consequently more liable to silting. Piers can range in size and complexity from a simple lightweight wooden structure to major structures extended over 1,600 m (5,200 ft). In American English, a pier may be synonymous with a dock.

Piers have been built for several purposes, and because these different purposes have distinct regional variances, the term pier tends to have different nuances of meaning in different parts of the world. Thus in North America and Australia, where many ports were, until recently, built on the multiple pier model, the term tends to imply a current or former cargo-handling facility. In contrast, in Europe, where ports more often use basins and river-side quays than piers, the term is principally associated with the image of a Victorian cast iron pleasure pier which emerged in Great Britain during the early 19th century. However, the earliest piers pre-date the Victorian age.

A pipeline bridge is a bridge for running a pipeline over a river or another obstacle. Pipeline bridges for liquids and gases are, as a rule, only built when it is not possible to run the pipeline on a conventional bridge or under the river. However, as it is more common to run pipelines for centralized heating systems overhead, for this application even small pipeline bridges are common.

Pipeline bridges may be made of steel, fiber reinforced polymer, reinforced concrete or similar materials. They may vary in size and style depending on the size of the pipeline being run. As there is normally a steady flow in pipelines, they can be designed as suspension bridges. They may also be added to an existing bridge. A pipeline bridge may be equipped with a walkway for maintenance purposes, but for safety and security reasons, the walkway is usually not open to the public.

A parapet is a barrier that is an upward extension of a wall at the edge of a roof, terrace, balcony, walkway or other structure. The word derives from the Italian parapetto (parare 'to cover/defend' and petto 'chest/breast'). Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires.
