Borrodale Viaduct
The Borrodale Viaduct is a railway viaduct that carries the West Highland Line over the Borrodale Burn. History In the decade after Borrodale was constructed, a large number of other concrete bridges were put up, whereas in the five years prior there were only three. Design The viaduct has a main span of , which at the time of its construction was the longest mass concrete Mass concrete is defined by American Concrete Institute Committee 207 as "any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from hydration of cement and attendant volume change ... span in the world. The original proposal was to have a conventional viaduct with piers in the gully, but the owner of Arisaig House insisted that the piers be clad in granite, so the design with the large span was settled on instead. The side spans are clad in dressed stone and are both of span . There is also a dressed stone parapet. The rise of the main ar ...

West Highland Line
The West Highland Line ( gd, Rathad Iarainn nan Eilean - "Iron Road to the Isles") is a railway line linking the ports of Mallaig and Oban in the Scottish Highlands to Glasgow in Central Scotland. The line was voted the top rail journey in the world by readers of independent travel magazine ''Wanderlust'' in 2009, ahead of the notable Trans-Siberian Railway, Trans-Siberian line in Russia and the PeruRail#Cusco_-_Aguas_Calientes_.28Machu_Picchu.29, Cuzco to Machu Picchu line in Peru. The ScotRail website has since reported that the line has been voted the most scenic railway line in the world for the second year running. The West Highland Line is one of two railway lines that access the remote and mountainous west coast of Scotland, the other being the Kyle of Lochalsh Line which connects Inverness with Kyle of Lochalsh. The line is the westernmost railway line in Great Britain. At least in part, the West Highland Line is the same railway line as that referred to as the West Hi ...

Mass Concrete
Mass concrete is defined by American Concrete Institute Committee 207 as "any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from hydration of cement and attendant volume change to minimize cracking."ACI Committee 207–Mass and Thermally Controlled Concrete As interior temperature of mass concrete rises due to the process of cement hydration, the outer concrete may be cooling and contracting. If the temperature differs too much within the structure, the material can crack. The main factors influencing temperature variation in the mass concrete structure are: the size of the structure, the ambient temperature, the initial temperature of the concrete at time of placement and curing program, the cement type, and the cement contents in the mix. Mass concrete structures include massive mat foundations, dam A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservo ...

Railway Bridges In Scotland
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lochaber
Lochaber ( ; gd, Loch Abar) is a name applied to a part of the Scottish Highlands. Historically, it was a provincial lordship consisting of the parishes of Kilmallie and Kilmonivaig, as they were before being reduced in extent by the creation of '' Quoad Sacra'' parishes in the 19th century. Lochaber once extended from the Northern shore of Loch Leven, a district called Nether Lochaber, to beyond Spean Bridge and Roybridge, which area is known as Brae Lochaber or ''Braigh Loch Abar'' in Gaelic. Lochaber is now also used to refer to a much wider area, one of the 16 ward management areas of the Highland Council of Scotland and one of eight former local government districts of the two-tier Highland region. The main town of Lochaber is Fort William. According to legend, a glaistig, a ghostly woman-goat hybrid, once lived in the area. Name William Watson outlined two schools of thought on this topic. He favoured the idea that ''Abar'' came from the Pictish and Welsh for " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bridges In Highland (council Area)
A bridge is a structure built to Span (engineering), 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. Etymology The ''Oxford English Dictionary'' traces ...
