Nyali Bridge
The Nyali Bridge is a concrete girder bridge connecting the city of Mombasa on Mombasa Island to the mainland of Kenya. The bridge crosses Tudor Creek (a tidal inlet) to the north-east of the island. The bridge is one of three road links out of Mombasa (the others being the Kipevu and Makupa Causeways). The Likoni Ferry provides a third transport link to the island, and is situated at the southern tip. The mainland approach to the bridge serves as a police checkpoint in both directions. Cost The ''Old Nyali Bridge'' (a floating bridge) stood approximately 800 m downstream from the current crossing. The floating bridge was commissioned by Governor Joseph Byrne in 1931. Details It is 391.65 metres long and 26.3 metres wide with a total of six lanes. The main bridge is 330 metres prestressed continuous box girder over three spans with the centre span of 150 metres. The outer spans are 90 metres each. The bridge is founded on piled foundation. The newer Nyali Bridge inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traffic
Traffic comprises pedestrians, vehicles, ridden or herded animals, trains, and other conveyances that use public ways (roads) for travel and transportation. Traffic laws govern and regulate traffic, while rules of the road include traffic laws and informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections. Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, or signs. Traffic is often classified by type: heavy motor vehicle (e.g., car, truck), other vehicle (e.g., moped, bicycle), and pedestrian. Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road while others rely more on drivers' common sense and willingness to cooperate. Organization ...

Police Checkpoint
Civilian checkpoints or security checkpoints are distinguishable from border or frontier checkpoints in that they are erected and enforced within contiguous areas under military or paramilitary control. Civilian checkpoints have been employed within conflict-ridden areas all over the world to monitor and control the movement of people and materials in order to prevent violence. They have also been used by police The police are a constituted body of persons empowered by a state, with the aim to enforce the law, to ensure the safety, health and possessions of citizens, and to prevent crime and civil disorder. Their lawful powers include arrest and th ... during peacetime to help counter terrorism. Contemporary examples Though practices and enforcement vary, checkpoints have been used in: * Airports and other transportation hubs across the world, including those managed by the Transportation Security Administration, TSA in the United States. * Post World War II checkp ...

Bridges In Kenya
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use.

Beam (structure)
A beam is a structural element that primarily resists Structural load, loads applied laterally to the beam's axis (an element designed to carry primarily axial load would be a strut or column). Its mode of Deflection (engineering), deflection is primarily by bending. The loads applied to the beam result in reaction forces at the beam's support points. The total effect of all the forces acting on the beam is to produce shear forces and bending moments within the beams, that in turn induce internal stresses, strains and deflections of the beam. Beams are characterized by their manner of support, profile (shape of cross-section), equilibrium conditions, length, and their material. Beams are traditionally descriptions of building or civil engineering structural elements, where the beams are horizontal and carry vertical loads. However, any structure may contain beams, for instance automobile frames, aircraft components, machine frames, and other mechanical or structural systems. In th ...

Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars ( rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontoon Bridge
A pontoon bridge (or ponton bridge), also known as a floating bridge, uses float (nautical), floats or shallow-draft (hull), draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load that they can carry. Most pontoon bridges are temporary and used in wartime and civil emergencies. There are permanent pontoon bridges in civilian use that can carry highway traffic. Permanent floating bridges are useful for sheltered water crossings if it is not considered economically feasible to suspend a bridge from anchored piers. Such bridges can require a section that is elevated or can be raised or removed to allow waterborne traffic to pass. Pontoon bridges have been in use since ancient times and have been used to great advantage in many battles throughout history, such as the Battle of Garigliano (1503), Battle of Garigliano, the Battle of Oudenarde, the Operation Plunder, crossing of the Rhine during World War II, the ...

Likoni Ferry
The Likoni Ferry is a ferry service across the Kilindini Harbour, serving the Kenyan city of Mombasa between the Mombasa island side and the mainland suburb of Likoni. Two - four double-ended ferries alternate across the harbour, carrying both road and foot traffic. The ferries are operated by the Kenya Ferry Services (KFS), and is the only remaining ferry service by KFS. The Likoni ferry started operating in 1937. Passenger services are free while vehicles, tuktuks, motorcycles and trucks have to pay a ferry toll. The Mombasa side terminal of the Likoni line is located at the southern end of the Mombasa Island. The distance of the line is about 500 metres. Service In addition to the main Likoni line, there is a passenger-only peak hour service between Mtongwe and Mombasa island next to Bandari College. It crosses the Kilindini Creek few kilometres west of the Kilindini line. The service was halted pending repairs of the ramp that was damaged. There are five operating ...

Pedestrians
A pedestrian is a person traveling on foot, whether walking or running. In modern times, the term usually refers to someone walking on a road or Road surface, pavement, but this was not the case historically. The meaning of pedestrian is displayed with the morphemes ''ped-'' ('foot') and ''-ian'' ('characteristic of'). This word is derived from the Latin term ''pedester'' ('going on foot') and was first used (in English language) during the 18th century. It was originally used, and can still be used today, as an adjective meaning plain or dull. However, in this article it takes on its noun form and refers to someone who walks. The word pedestrian may have been used in middle French in the :fr:Recueil des Croniques et Anchiennes Istories de la Grant Bretaigne, à présent nommé Engleterre, Recueil des Croniques et Anchiennes Istories de la Grant Bretaigne, à présent nommé Engleterre.
