An overpass (called a flyover in the UK The United Kingdom of Great Britain and Northern Ireland is a sovereign state located off the northwestern coast of continental Europe. It is an island country, spanning an archipelago including Great Britain, the northeastern part of Ireland, and many small islands. Northern Ireland is the only part of the UK with a land border, sharing it with and most Commonwealth The Commonwealth of Nations, often referred to as the Commonwealth and previously as the British Commonwealth, is an intergovernmental organisation of fifty-four independent member states, all but two of which were formerly part of the British Empire. The member states co-operate within a framework of common values and goals as outlined in the countries) is a bridge A bridge is a structure built to span a valley, road, body of water, or other physical obstacle, for the purpose of providing passage over the obstacle. Designs of bridges vary depending on the function of the bridge and the nature of the terrain where the bridge is constructed, road A road is an identifiable route, way or path between places. Roads are typically smoothed, paved, or otherwise prepared to allow easy travel; though they need not be, and historically many roads were simply recognizable routes without any formal construction or maintenance, railway Rail transport is the conveyance of passengers and goods by means of wheeled vehicles running on steel rails. Rail transport is part of the logistics chain, which facilitates international trade and economic growth. Rail transport is capable of high capacity and is energy efficient, but lacks flexibility and is capital intensive or similar structure Structure is a fundamental and sometimes intangible notion covering the recognition, observation, nature, and stability of patterns and relationships of entities. From a child's verbal description of a snowflake, to the detailed scientific analysis of the properties of magnetic fields, the concept of structure is an essential foundation of nearly that crosses over another road or railway. An overpass structure is one that carries a higher capacity road above a lower capacity road, whereas a structure that permits a lower capacity road to travel above a larger capacity road is an underpass A tunnel is an underground passageway. The definition of what constitutes a tunnel is not universally agreed upon. However, in general tunnels are at least twice as long as they are wide. In addition, they should be completely enclosed on all sides, save for the openings at each end. Some civic planners define a tunnel as 0.1 miles in length or.[citation needed] Capacity is determined as either the number of lanes of travel provided or measured traffic count. In instances of actual or perceived equality between the traffic flows, the term structure can be used.[citation needed]
In North America, a flyover is a high-level overpass, built above main overpass lanes, or a bridge built over what had been an at-grade intersection An at-grade intersection is a junction at which two or more transport axes cross at the same level. Traffic engineers usually refer to the latter as a grade separation Grade separation is the process of aligning a junction of two or more transport axes at different heights so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads, footpaths, railways, canals, or. A flyover may also be an extra ramp added to an existing interchange, either replacing an existing cloverleaf A cloverleaf interchange is a two-level interchange in which left turns are handled by loop roads (U.S.: ramps, UK: slip roads). To go left (in right-hand traffic), vehicles first pass either over or under the other road, then turn right onto a one-way three-fourths loop ramp (270°) and merge onto the intersecting road loop (or being built in place of one) with a higher, faster ramp that bears left. Such a ramp may be built as a right or left exit.
A pedestrian overpass allows pedestrians A pedestrian is a person traveling on foot, whether walking or running. In some communities, those traveling using roller skates, skateboards, and similar devices are also considered to be pedestrians. In modern times, the term mostly refers to someone walking on a road or footpath, but this was not the case historically safe crossing over busy roads without impacting traffic.

- Footbridge A footbridge or pedestrian bridge is a bridge designed for pedestrians and in some cases cyclists, animal traffic and horse riders, rather than vehicular traffic. In many developed countries, footbridges are both functional and can be beautiful works of art and sculpture. For poor rural communities in the developing world, a footbridge may be a
- Skyway In an urban setting, a skyway, catwalk, sky bridge, or skywalk is a type of pedway consisting of an enclosed or covered bridge between two buildings. This protects pedestrians from the weather. These skyways are usually owned by businesses, and are therefore not public spaces . Skyways usually connect on the first few floors above the ground-level
