Avoncliff Aqueduct
Avoncliff Aqueduct () carries the Kennet and Avon Canal over the River Avon and the Bath to Westbury railway, at Avoncliff in Wiltshire, England, about west of Bradford-on-Avon. It was built by John Rennie and chief engineer John Thomas, between 1797 and 1801. It is a Grade II* listed structure. During construction, stone from a local quarry was used which split when affected by frost. This caused buttresses to collapse and parts of the structure to need rebuilding. Eventually Bath stone from Bathampton Down was used to ensure greater stability. The aqueduct has three arches and is long, with a central elliptical arch of 60 ft (18.3 m) span, and two semicircular side arches each 34 ft (10.4 m) across, all with V-jointed arch stones. The spandrel and wing walls are built in alternate courses of ashlar masonry and rock-faced blocks. The central span sagged soon after it was built and has been repaired many times. As part of the 20th-century restorati ... [...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] |
Aqueduct (bridge)
Aqueducts (or water bridges) are bridges constructed to convey watercourses across gaps such as valleys or ravines. The term ''aqueduct'' may also be used to refer to the entire watercourse, as well as the bridge. Large navigable aqueducts are used as transport links for boats or ships. Aqueducts must span a crossing at the same level as the watercourses on each end. The word is derived from the Latin ' ("water") and ' ("to lead"), therefore meaning "to lead water". A modern version of an aqueduct is a pipeline bridge. They may take the form of tunnels, networks of surface channels and canals, covered clay pipes or monumental bridges. Ancient bridges for water Although particularly associated with the Romans, aqueducts were likely first used by the Minoans around 2000 BCE. The Minoans had developed what was then an extremely advanced irrigation system, including several aqueducts. In the seventh century BCE, the Assyrians built an 80 km long limestone aqueduct, w ...

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.

Bridges Completed In 1805
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.

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. It is a Grade I listed building In the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navigable Aqueduct
Navigable aqueducts (sometimes called water bridges) are bridge structures that carry navigable waterway canals over other rivers, valleys, railways or roads. They are primarily distinguished by their size, carrying a larger cross-section of water than most water-supply aqueducts. Roman aqueducts were used to transport water and were created in Ancient Rome. The long steel Briare aqueduct carrying the Canal latéral à la Loire over the River Loire was built in 1896. It was ranked as the longest navigable aqueduct in the world for more than a century, until the Magdeburg Water Bridge in Germany took the title in the early 21st century. Early aqueducts such as the three on the Canal du Midi had stone or brick arches, the longest span being on the Cesse Aqueduct, built in 1690. But, the weight of the construction to support the trough with the clay or other lining to make it waterproof made these structures clumsy. In 1796 Longdon-on-Tern Aqueduct, the first large cast ir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avoncliff Railway Station
Avoncliff railway station serves the hamlet of Avoncliff in Wiltshire, England, together with the nearby villages of Westwood and Winsley, and Turleigh hamlet. It is next to the Kennet and Avon Canal and almost adjacent to the Avoncliff Aqueduct, so it is popular with walkers and cyclists who wish to travel along the canal path or the picturesque walks around the station. The station has two platforms, each long enough for coaches, with a waiting shelter and original lamp-posts, and is served by Great Western Railway. Residents have voluntarily decorated the station with pots of flowers and, to mark its 100-year anniversary on 9 July 2006, decorated the station with bunting and dressed in Victorian clothing for the celebrations. History Opened on the Wessex Main Line by the Great Western Railway as Avoncliff Halt on 9 July 1906, it remained part of that company during the Grouping of 1923. The station then passed to the Western Region of British Railways on nationalisation i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bathampton Down
Bathampton Down is a flat limestone plateau in Bathampton, Somerset, England, overlooking the River Avon and the city of Bath. There is evidence of man's activity at the site since the Mesolithic period including Bathampton Camp, an Iron Age hillfort or stock enclosure. It has also been used for quarrying, and part of it is now a golf course. Geography The plateau is formed from the Greater Oolitic Limestone with formations including Forest Marble, Bath Oolite, Twinhoe Beds and Combe Down Oolite. The limestone dates from the Middle Jurassic with deposits of flint quartz and sandstone, mainly preserved in fissures or other cavities dating from the Middle Pleistocene. The limestone is porous which, along with the flat nature of the plateau means there are no streams or rivers, particularly as several cold springs on Bathampton Down were diverted into reservoirs in the late 18th and early 19th centuries having originally flowed down to the River Avon. The southern area merges w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
