Semington Aqueduct
Semington Aqueduct () is an aqueduct at Semington, Wiltshire, England, UK. It carries the Kennet and Avon Canal over the Semington Brook. History The Kennet and Avon Canal was the realisation of a plan to link the River Avon to the River Thames and hence Bristol to London, which had first been suggested in the late 1500s, during the reign of Queen Elizabeth I. The canal was surveyed by John Rennie and following a change of route, which resulted in the canal passing through Devizes and hence Semington, rather than Marlborough and Calne, an Act of Parliament was obtained in 1794 to authorise the plan and work began. The eastern section opened first, with the line from Newbury and the River Kennet to Hungerford opening in 1798, and from there to Great Bedwyn opening the following year. The western section through Semington was partially complete by this time, and was finished by 1804, but there were two gaps to be filled. These were the locks at Bath which connected the canal to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kennet And Avon Canal
The Kennet and Avon Canal is a waterway in southern England with an overall length of , made up of two lengths of navigable river linked by a canal. The name is used to refer to the entire length of the navigation rather than solely to the central canal section. From Bristol to Bath the waterway follows the natural course of the River Avon before the canal links it to the River Kennet at Newbury, and from there to Reading on the River Thames. In all, the waterway incorporates 105 locks. The two river stretches were made navigable in the early 18th century, and the canal section was constructed between 1794 and 1810. In the late 19th and early 20th centuries, the canal gradually fell into disuse after the opening of the Great Western Railway. In the latter half of the 20th century the canal was restored in stages, largely by volunteers. After decades of dereliction and much restoration work, it was fully reopened in 1990. The Kennet and Avon Canal has been developed as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lune Aqueduct
The Lune Aqueduct is a navigable aqueduct that carries the Lancaster Canal over the River Lune, on the east side of the city of Lancaster in Lancashire, England. It was completed in 1797 at a total cost of £48,320 18s 10d. It is a Grade I listed building. Construction The aqueduct was designed by civil engineer John Rennie and constructed by architect Alexander Stevens (died 1796, aged 66). The cost of the construction was close to £50,000. The aqueduct is a traditional structure of that time, consisting of five stone arches supporting the stone trough. Within the piers, special volcanic pozzolana powder was imported to be mixed with cement, which allowed the concrete to set under water. Because of the rush to finish the initial stages, before the winter floods, the construction was carried out around the clock and the final bill for the project was over £30,000 over budget (2.6 times the original estimate). This vast overspend was the reason that the Lancaster canal was n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navigable Aqueducts In England
A body of water, such as a river, canal or lake, is navigable if it is deep, wide and calm enough for a water vessel (e.g. boats) to pass safely. Such a navigable water is called a ''waterway'', and is preferably with few obstructions against direct traverse that needed avoiding, such as rocks, reefs or trees. Bridges built over waterways must have sufficient clearance. High flow speed may make a channel unnavigable due to risk of ship collisions. Waters may be unnavigable because of ice, particularly in winter or high-latitude regions. Navigability also depends on context: a small river may be navigable by smaller craft such as a motorboat or a kayak, but unnavigable by a larger freighter or cruise ship. Shallow rivers may be made navigable by the installation of locks that regulate flow and increase upstream water level, or by dredging that deepens parts of the stream bed. Inland water transport systems Inland Water Transport (IWT) Systems have been used for centuries i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges Completed In 1807
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 wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semington Locks
The Semington Locks () are situated at Semington, Wiltshire on the Kennet and Avon Canal, England. They have a combined rise/fall of 16 feet 1 inch (4.9 m). The two locks at Semington are known as Buckley's (No.15) and Barrett's (No.16). Adjacent to the locks is the point at which the former Wilts and Berks Canal joined the Kennet and Avon. Close by, the Grade II listed Semington Aqueduct carries the canal over the Semington Brook. East of the locks, the canal crosses the New Semington Aqueduct, built in 2004 to bridge the newly constructed Semington village bypass ( A350 road).

New Semington Aqueduct
New Semington Aqueduct () carries the Kennet and Avon Canal over the carriageway of the A350 road Trowbridge Bypass, at Semington in west Wiltshire, England. Although the construction of new canals is no longer common practice in England, new aqueducts such as this are sometimes built in relation to new roads or road widening schemes. Details The new aqueduct was built under the provisions of The Wiltshire County Council (Semington Aqueduct) Scheme 2000, later confirmed on 17 July 2002, as Statutory Instrument No. 1868. It was part of a road-building scheme to provide a bypass for the villages of Semington, to the west of the new structure, and Berryfield to the north of the canal, ending on the southern edge of Melksham. In order to provide the necessary headroom of , the road was built in a cutting at this point. The new structure is on the line of the original canal. In order to allow it to be built without closing the canal for the duration of the project, the canal wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grade II Listed
In the United Kingdom, a listed building or listed structure is one that has been placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, in Wales, and the Northern Ireland Environment Agency in Northern Ireland. The term has also been used in the Republic of Ireland, where buildings are protected under the Planning and Development Act 2000. The statutory term in Ireland is "protected structure". A listed building may not be demolished, extended, or altered without special permission from the local planning authority, which typically consults the relevant central government agency, particularly for significant alterations to the more notable listed buildings. In England and Wales, a national amenity society must be notified of any work to a listed building which involves any element of demolition. Exemption from secular listed building control is provided for some buildings in current use for worship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ashlar
Ashlar () is finely dressed (cut, worked) stone, either an individual stone that has been worked until squared, or a structure built from such stones. Ashlar is the finest stone masonry unit, generally rectangular cuboid, mentioned by Vitruvius as opus isodomum, or less frequently trapezoidal. Precisely cut "on all faces adjacent to those of other stones", ashlar is capable of very thin joints between blocks, and the visible face of the stone may be quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect. One such decorative treatment consists of small grooves achieved by the application of a metal comb. Generally used only on softer stone ashlar, this decoration is known as "mason's drag". Ashlar is in contrast to rubble masonry, which employs irregularly shaped stones, sometimes minimally worked or selected for similar size, or both. Ashlar is related but distinct from other stone masonry tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for lime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limpley Stoke
Limpley Stoke is a village and civil parish in Wiltshire, England. It lies in the Avon valley between Bath and Freshford, and is both above and below the A36 road. The parish is surrounded to the north, west and south by the Bath and North East Somerset district and includes the outskirts of the Somerset villages of Freshford and Midford. The Avon forms the eastern boundary of the parish, and its tributary the Midford Brook is the boundary in the north and west. History The 18th-century country house at Waterhouse is a Grade II listed building. Limpley Stoke was the westernmost part of the ancient hundred of Bradford, and a tithing of Bradford parish, which was divided into civil parishes in 1894. A small Baptist chapel was built on Middle Stoke in 1815 and rebuilt in 1888, providing 150 seats. The chapel closed in the 1970s. A National School was opened on Middle Stoke in 1845; in 1893 there were 51 pupils. The school closed in 1932 owing to low pupil numbers, and the bui ...

Dundas Aqueduct
Dundas Aqueduct () carries the Kennet and Avon Canal over the River Avon (the Somerset / Wiltshire border) and the Wessex Main Line railway from Bath to Westbury. The aqueduct is near Monkton Combe, Somerset, and is about southeast of the city of Bath. It was designed by John Rennie and chief engineer John Thomas between 1797 and 1801, and completed in 1805. James McIlquham was appointed contractor. It is named after Charles Dundas, the first chairman of the Kennet and Avon Canal Company. The aqueduct is long with three arches built of Bath Stone, with Doric pilasters, and balustrades at each end. The central semi-circular arch spans ; the two oval side arches span . The canal crosses back across the Avon and the railway on another aqueduct at Avoncliff. This diversion onto the right bank of the Avon avoids the steep sides of the river valley at Limpley Stoke, and the need to cross the Midford Brook and River Frome.
