Tubular Bridge
A tubular bridge is a bridge built as a rigid box girder section within which the traffic is carried. Famous examples include the original Britannia Bridge over the Menai Strait, the Conwy railway bridge over the River Conwy, designed and tested by William Fairbairn and built by Robert Stephenson between 1846 and 1850, and the original Victoria Bridge in Montreal. Conwy and Britannia Bridges The Conwy railway bridge carries the North Wales coast railway line across the River Conwy between Llandudno Junction and the town of Conwy. The wrought iron tubular bridge was built by Robert Stephenson to a design by William Fairbairn, and is similar in construction to Stephenson's other famous tubular bridge, the Britannia Bridge across the Menai Strait. It was officially opened in 1849, but had been completed in 1848. Being the first tubular bridge to be built, the design needed much testing on prototypes to confirm that it would be capable of carrying heavy locomotives, the testing ...

Conwy Railway Bridge
The Conwy Railway Bridge carries the North Wales coast railway line across the River Conwy between Llandudno Junction and the town of Conwy. The wrought iron tubular bridge, which is now Grade I listed, was built in the 19th century. It is the last surviving example of this type of design by Stephenson after the original Britannia Bridge across the Menai Strait was partially destroyed in a fire in 1970 and rebuilt as a two-tier truss arch bridge design. The Conwy Railway Bridge was designed by railway engineer Robert Stephenson in collaboration with William Fairbairn and Eaton Hodgkinson. The original plan had been for suspension bridge complementing Thomas Telford's Conwy Suspension Bridge of 1826. After Stephenson's appointment as chief engineer, the design was changed because a suspension bridge was considered unsuitable for trains. Stephenson and his collaborators invented the wrought-iron box-girder structure to bridge the River Conwy in a single span. During May 1846, ...

Conwy
Conwy (, ), previously known in English as Conway, is a walled market town, community and the administrative centre of Conwy County Borough in North Wales. The walled town and castle stand on the west bank of the River Conwy, facing Deganwy on the east bank. The town formerly lay in Gwynedd and prior to that in Caernarfonshire. The community, which also includes Deganwy and Llandudno Junction, had a population of 14,753 at the 2011 census. Although the community of Conwy straddles the River Conwy, for postal purposes the areas on the east bank form part of the post town of Llandudno Junction, with the Conwy post town being confined to west bank of the river. The ward on the west bank of the river had a population of 4,065 at the 2011 census. The resident population of the wider Conwy County Borough was estimated to be 116,200 in an ONS-estimate. The name 'Conwy' derives from the old Welsh words ''cyn'' (chief) and ''gwy'' (water), the river being originally called the 'Cynwy ...

Box Girder Bridge
A box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section. Box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although the box girder bridge is normally a form of beam bridge, box girders may also be used on cable-stayed and other bridges. Development of steel box girders In 1919, Major Gifford Martel was appointed head of the Experimental Bridging Establishment at Christchurch, Hampshire, which researched the possibilities of using tanks for battlefield engineering purposes such as bridge-laying and mine-clearing. Here he continued trials on modified Mark V tanks. The bridging component involved an assault bridge, designed by Major Charle ...

Torksey
__NOTOC__ Torksey is a small village in the West Lindsey district of Lincolnshire, England. The population of the civil parish at the 2011 census was 875. It is situated on the A156 road, south of Gainsborough and north-west of the city of Lincoln, and on the eastern bank of the tidal River Trent, which here forms the boundary with Nottinghamshire. It is notable historically as the site of a Roman canal, a major Viking camp, the late medieval Torksey Castle and the Torksey Viaduct. History Foss Dyke, a Roman canal constructed in or about the 2nd century, joins the River Trent by way of a series of lock-gates about half a mile (800 m) south of the village. During the 9th century, Torksey was part of the Anglo-Saxon Kingdom of Lindsey. In the late 860s, a Viking invasion force known to the English as the "Great Heathen Army" conquered eastern England. In 871–2, the Vikings established a winter camp in London, but returned to Northumbria soon afterwards, following a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Albert Bridge
The Royal Albert Bridge is a railway bridge which spans the River Tamar in England between Plymouth, Devon and Saltash, Cornwall. Its unique design consists of two lenticular iron trusses above the water, with conventional plate-girder approach spans. This gives it a total length of . It carries the Cornish Main Line railway in and out of Cornwall. It is adjacent to the Tamar Bridge which opened in 1962 to carry the A38 road. The Royal Albert Bridge was designed by Isambard Kingdom Brunel. Surveying started in 1848 and construction commenced in 1854. The first main span was positioned in 1857 and the completed bridge was opened by Prince Albert on 2 May 1859. Brunel died later that year and his name was then placed above the portals at either end of the bridge as a memorial. During the 20th century the approach spans were replaced, and the main spans strengthened. It has attracted sightseers since its construction and has appeared in many paintings, photographs, guidebook ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Wales
Wales ( cy, Cymru ) is a country that is part of the United Kingdom. It is bordered by England to the east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of . Wales has over of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (), its highest summit. The country lies within the north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The conquest of Wales by Edward I of England was completed by 1283, though Owain Glyndŵr led the Welsh Revolt against English rule in the early 15th century, and briefly re-establis ...

River Wye
The River Wye (; cy, Afon Gwy ) is the fourth-longest river in the UK, stretching some from its source on Plynlimon in mid Wales to the Severn estuary. For much of its length the river forms part of the border between England and Wales. The Wye Valley (lower part) is designated an Area of Outstanding Natural Beauty. The Wye is important for nature conservation and recreation, but is severely affected by pollution. Etymology The meaning of the river's name is not clear. Possibly the earliest reference to the name is ''Guoy'' in Nennius' early 9th Century '' Historia Brittonum'' and the modern Welsh name is ''Gwy''. The Wye was much later given a Latin name, ''Vaga'', an adjective meaning 'wandering'. The Tithe map references a Vagas Field in both Whitchurch and Chepstow. Philologists such as Edward Lye and Joseph Bosworth in the 18th and early 19th centuries suggested an Old English derivation from ''wæg'', "wave". Description The source of the Wye is in the Wels ...

Isambard Kingdom Brunel
Isambard Kingdom Brunel (; 9 April 1806 – 15 September 1859) was a British civil engineer who is considered "one of the most ingenious and prolific figures in engineering history," "one of the 19th-century engineering giants," and "one of the greatest figures of the Industrial Revolution, hochanged the face of the English landscape with his groundbreaking designs and ingenious constructions." Brunel built dockyards, the Great Western Railway (GWR), a series of steamships including the first propeller-driven transatlantic steamship, and numerous important bridges and tunnels. His designs revolutionised public transport and modern engineering. Though Brunel's projects were not always successful, they often contained innovative solutions to long-standing engineering problems. During his career, Brunel achieved many engineering firsts, including assisting in the building of the first tunnel under a navigable river (the River Thames) and the development of the , the f ...
