Skyway
A skyway, skybridge, skywalk, or sky walkway is an elevated type of pedway connecting two or more buildings in an urban area, or connecting elevated points within mountainous recreational zones. Urban skyways very often take the form of Covered bridge, enclosed or covered footbridges that protect pedestrians from the weather. Open-top modern skyways in mountains now often have glass bottoms. Sometimes enclosed urban skywalks are made almost totally from glass, including ceilings, walls and floors. Also, some urban skyways function strictly as linear parks designed for walking. In North America skyways are usually owned by businesses, and are therefore not public spaces as compared with sidewalks. However, in Asia, such as Bangkok's and Hong Kong's skywalks, they are built and owned separately by the city government, connecting between privately run rail stations or other transport with their own footbridges, and run many kilometers. Skyways usually connect on the first few flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pier (architecture)
A pier, in architecture, is an upright support for a structure or superstructure such as an arch or bridge. Sections of structural walls between openings (bays) can function as piers. External or free-standing walls may have piers at the ends or on corners. Description The simplest cross section (geometry), cross section of the pier is square (geometry), square, or rectangle, rectangular, but other shapes are also common. In medieval architecture, massive circle, circular supports called drum piers, cruciform (cross-shaped) piers, and compound piers are common architectural elements. Columns are a similar upright support, but stand on a round base; in many contexts columns may also be called piers. In buildings with a sequence of Bay (architecture), bays between piers, each opening (window or door) between two piers is considered a single bay. Bridge piers Single-span bridges have abutments at each end that support the weight of the bridge and serve as retaining walls to res ...

Traffic Congestion
Traffic congestion is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular queueing. Traffic congestion on urban road networks has increased substantially since the 1950s, resulting in many of the roads becoming obsolete. When traffic demand is great enough that the interaction between vehicles slows the traffic stream, this results in congestion. While congestion is a possibility for any mode of transportation, this article will focus on automobile congestion on public roads. Mathematically, traffic is modeled as a flow through a fixed point on the route, analogously to fluid dynamics. As demand approaches the capacity of a road (or of the intersections along the road), extreme traffic congestion sets in. When vehicles are fully stopped for periods of time, this is known as a traffic jam or (informally) a traffic snarl-up or a tailback. Drivers can become frustrated and engage in road rage. Drivers and driver-focused r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arlington Memorial Bridge
The Arlington Memorial Bridge, often shortened to Memorial Bridge, is a Neoclassical masonry, steel, and stone arch bridge with a central bascule (or drawbridge) that crosses the Potomac River in Washington, D.C., the capital of the United States. First proposed in 1886, the bridge went unbuilt for decades thanks to political quarrels over whether the bridge should be a memorial, and to whom or what. Traffic problems associated with the dedication of the Tomb of the Unknown Soldier in November 1921 and the desire to build a bridge in time for the bicentennial of the birth of George Washington led to its construction in 1932. Designed by the architectural firm McKim, Mead, and White, decorated with monumental statues depicting valor and sacrifice by sculptor Leo Friedlander, and cast by Ferdinando Marinelli Artistic Foundry of Florence, Italy, Arlington Memorial Bridge defines the western end of the National Mall.
