Leaderfoot Viaduct
The Leaderfoot Viaduct, also known as the Drygrange Viaduct, is a railway viaduct over the River Tweed near Melrose in the Scottish Borders. History The viaduct was opened on 16 November 1863 to carry the Berwickshire Railway, which connected Reston with St Boswells, via Duns and Greenlaw. The engineers of the railway were Charles Jopp and Wylie & Peddie. The railway was severely damaged by flooding during August 1948, with 7 bridges on the line failing, and the line closed to passenger traffic on 13 August 1948. Freight trains continued to run across the viaduct as far as Greenlaw until 19 July 1965. In 1981, the poor condition of the viaduct meant that it was due to be demolished. It was upgraded from Category B to A listing in 1986. Historic Scotland took over control of the viaduct from British Rail in 1996. Design The viaduct stands from the floor of the river valley. The arches, each of span, are of brickwork, and the abutments, piers and walls are of rustic-face ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Tweed
The River Tweed, or Tweed Water ( gd, Abhainn Thuaidh, sco, Watter o Tweid, cy, Tuedd), is a river long that flows east across the Border region in Scotland and northern England. Tweed cloth derives its name from its association with the River Tweed. The Tweed is one of the great salmon rivers of Britain and the only river in England where an Environment Agency rod licence is not required for angling. The river generates a large income for the local borders region, attracting anglers from all around the world. Etymology ''Tweed'' may represent an Old Brittonic name meaning "border". A doubtful proposal is that the name is derived from a non-Celtic form of the Indo-European root ''*teuha-'' meaning "swell, grow powerful". Course The River Tweed flows primarily through the scenic Borders region of Scotland. Eastwards from the settlements on opposing banks of Birgham and Carham it forms the historic boundary between Scotland and England. It rises in the Lowther Hills at ...

Abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end which provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus of a column in classical architecture may also serve as an abutment to an arch. The word derives from the verb "abut", meaning to "touch by means of a mutual border". Use in engineering An abutment may be us ...

Viaducts In Scotland
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains there, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bridges In The Scottish Borders
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. Etymology The ''Oxford English Dictionary'' traces the origin of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 faciliti ...

River Leader
The River Leader, or Leader Water, is a small tributary of the River Tweed in Lauderdale in the Scottish Borders. It flows southwards from the Lammermuir Hills through the towns of Lauder and Earlston, joining the River Tweed at Leaderfoot. Course The feeder burns of the Leader Water are the Headshaw Burn, the Hillhouse Burn and the Kelphope Burn. They combine at the Carfrae mill hotel and the village of Oxton. The river is now sandwiched between the A68 and the A697, and it has absorbed the Cleekhimin Burn, Harry Burn, Washing Burn and Earnscleugh Burn. The Leader Water now passes to the east of the town of Lauder, by Thirlestane Castle. The A679 bridges the river which continues past Lauder Barns, West Mains and St. Leonards where the Leader receives his final feeder burn, the Boondreigh Burn. It now sticks closely by the A68, near the Whitslaid Tower, the Blainslies, Galadean, Birkhill, Chapel-on-Leader and Leadervale. After passing through the outskirts of Earlston, the ...

Drygrange Old Bridge
The Drygrange Old Bridge is a disused road bridge over the River Tweed near Melrose in the Scottish Borders. History It was built between 1776 and 1780 to a design by Scottish architect and engineer Alexander Stevens. It replaced a ferry as part of an improvement to a turnpike road. It was listed as a Category A listed building in 1971. It carried the A68 over the Tweed until 1974 when it was replaced by a box girder bridge to the east, engineered by Sir Alexander Gibb & Partners Sir Alexander Gibb & Partners was a British firm of consulting civil engineers, based at Queen Anne's Lodge, Queen Anne's Gate and subsequently Telford House, Tothill Street, Westminster, London, until 1974, when it relocated to Earley House, 427 ....

Trimontium (Newstead)
Trimontium was a Roman fort complex in Scotland. It is located at Newstead, near Melrose, in the Scottish Borders, in view of the three Eildon Hills which probably gave its name (Latin: ''trium montium'', three hills). It was occupied from about 79 AD to 184 AD and was the largest of the "outpost" forts with associated ''vicus'' (settlement) still occupied after the construction of Hadrian's Wall in the 120s AD. It was located 60 miles north of the wall in seemingly "hostile" territory. Trimontium was about three times as big as any fort on Hadrian's Wall and in the later period became the most northerly settlement of the whole Roman Empire. Trimontium is also considered of international importance as the site of one of the largest caches of Roman military objects in Britain, found in 117 pits. It was identified by Ptolemy in his ''Geography.'' The fort sits on the banks of the River Tweed, with the Eildon Hills and the Iron Age hillfort atop Eildon North, a visible remin ...

Cutwater
In architecture, a starling (or sterling) is a defensive bulwark, usually built with pilings or bricks, surrounding the supports (or piers) of a bridge or similar construction. Starlings may be shaped to ease the flow of the water around the bridge, reducing the damage caused by erosion or collisions with flood-borne debris, and may also form an important part of the structure of the bridge, spreading the weight of the piers. The term cutwater is used for such a structure shaped with water flow in mind, as a pier or starling with a diamond point. A starkwater is a bulwark against ice floes. Depending on their shape and location, some starlings may accumulate river debris, mud and other objects, potentially creating navigational hazards or hindering downstream water flow. Shape Starlings may form part of a buttress for the vertical load of the bridge piers, and for that purpose would typically be symmetrical. Examples such as at the Old Wye Bridge, Chepstow are on lower stretc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grout
Grout is a dense fluid which hardens to fill gaps or used as reinforcement in existing structures. Grout is generally a mixture of water, cement and sand, and is employed in pressure grouting, embedding rebar in masonry walls, connecting sections of pre-cast concrete, filling voids, and sealing joints such as those between tiles. Common uses for grout in the household include filling in tiles of shower floors and kitchen tiles. It is often color tinted when it has to be kept visible and sometimes includes fine gravel when being used to fill large spaces (such as the cores of concrete blocks). Unlike other structural pastes such as plaster or joint compound, correctly mixed and applied grout forms a water resistant seal. Although both grout and its close relative mortar are applied as a thick emulsion and harden over time, grout is distinguished by its low viscosity and lack of lime (added to mortar for pliability); grout is thin so it flows readily into gaps, while mortar is ...
