Tinsley Viaduct
Tinsley Viaduct is a two-tier road bridge in Sheffield, England; it was the first of its kind in the United Kingdom. It carries the M1 and the A631 for a distance of over the Don Valley, from Tinsley to Wincobank, also crossing the Sheffield Canal, the Midland Main Line and the former South Yorkshire Railway line from Tinsley Junction to Rotherham Central. The Supertram route to Meadowhall runs below part of the viaduct on the trackbed of the South Yorkshire Railway line to Barnsley. History The lower deck of the viaduct was opened in March 1968 and the upper deck, carrying the M1, on 19 October 1968. The build cost was £6 million. The structure is unusual in that it is built as steel box girders, at a time when most long span bridges were being built of post-tensioned concrete deck design. The use of steel allowed a significant cost saving over alternative methods, but became controversial following two disasters involving steel bridges in 1970 (the West Gate Bri ...

Meadowhall (shopping Centre)
Meadowhall is an indoor shopping centre in Sheffield, South Yorkshire, England. It lies north-east of Sheffield city centre, and from Rotherham town centre. It is the largest shopping centre in Yorkshire, and currently the eleventh-largest in the United Kingdom. As of 2021, plans for an extension are currently under consideration, for completion in the 2020s, which would make Meadowhall the fourth-largest shopping centre in the United Kingdom. Architecturally, the original construction of Meadowhall in the early 1990s was inspired by the Place d'Orléans shopping centre in Ottawa, Canada. The Meadowhall Retail Park is a separate development, owned by British Land, lying almost to the south of Meadowhall shopping centre in the Carbrook area of the city. History The shopping centre was built by Bovis on the site previously occupied by Hadfields' East Hecla steelworks. The centre was opened on 4 September 1990. With a floor area of , it is the eleventh-largest (second-l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotherham Railway Station
Rotherham Central railway station is in Rotherham, South Yorkshire, England. The station was originally named "Rotherham", becoming "Rotherham and Masborough" in January 1889 and finally "Rotherham Central" on 25 September 1950. The station has retained its "Central" suffix, despite being the only railway station in Rotherham since the closure of in 1988. History This is the fourth station to be built, within the town centre, on the line from . The first, a single platform terminus was built on what became the coal yard by the South Yorkshire Railway (SYR). Today this approximates to the land off Brinsworth Street below the bridge which carries the Inner Relief Road over the railway. The SYR could not gain permission to pass below the already built line of the Sheffield and Rotherham Railway, opened in 1838. A few years later and following amalgamation into the Manchester, Sheffield and Lincolnshire Railway (MS&LR), a scheme was developed to fill the South Yorkshire Naviga ...

Highways Agency
National Highways, formerly the Highways Agency and later Highways England, is a government-owned company charged with operating, maintaining and improving motorways and major A roads in England. It also sets highways standards used by all four UK administrations, through the Design Manual for Roads and Bridges. Within England, it operates information services through the provision of on-road signage and its Traffic England website, provides traffic officers to deal with incidents on its network, and manages the delivery of improvement schemes to the network. Founded as an executive agency, it was converted into a government-owned company, Highways England, on 1 April 2015. As part of this transition, the UK government set out its vision for the future of the English strategic road network in its Road Investment Strategy. A second Road Investment Strategy was published in March 2020, with the company set to invest £27 billion between 2020 and 2025 to improve the network as d ...

European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a '' sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agreed to act ...

British Construction Industry Awards
The British Construction Industry Awards (BCI Awards or BCIA) were launched by ''New Civil Engineer'' magazine and Thomas Telford Ltd in 1998, at the time both owned by the Institution of Civil Engineers. The awards seek to recognise outstanding achievement in the construction of buildings, taking account of a wide range of factors including architectural and engineering design, but also consideration of the construction process, delivery to time and budget, and client satisfaction. In 2012, Network Rail chief executive Sir David Higgins was the chair of the British Construction Industry Awards judging panel which celebrated its 25th anniversary of rewarding excellence in UK construction delivery. In June 2017 owners of New Civil Engineer, Ascential, sold the title to Metropolis International who now operate the BCIAs in association with the Institution of Civil Engineers. The awards are typically held in October each year. In 2020, the British Construction Industry Awards will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cleddau Bridge
The Cleddau Bridge (, cy, Pont Cleddau) in Pembrokeshire, Wales, carries the A477 road over the River Cleddau between Neyland and Pembroke Dock. Errors in the box girder design caused the collapse during construction in 1970. The bridge became operational during 1975. The bridge is managed by Pembrokeshire County Council. History Pembrokeshire is divided by the Cleddau. Hobbs Point in Pembroke Dock on the south side and Neyland on the north side are less than apart across the waterway but to drive from one to the other, a journey of by road was required. Between 1858 and 1950, the Admiralty permitted operation of steam ferries between the two towns. From 1950, the County Council operated a ferry service, with capacity for 24 vehicles and 250 pedestrians. A decision was taken in the 1960s to replace the ferry service: two bridges would be required, one crossing the Cleddau and a smaller bridge to the north of Neyland crossing Westfield Pill creek.

Post-tensioned Concrete
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" ( compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. Post-tensioned concreted is "structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads." This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire strands or threaded bars that are most commonly made from high-tensile steels, carbon fiber or aramid fiber. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concrete when subject to any subsequent compression forces and of ductile high-strength steel when subje ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Guardian
''The Guardian'' is a British daily newspaper. It was founded in 1821 as ''The Manchester Guardian'', and changed its name in 1959. Along with its sister papers ''The Observer'' and ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. Since 2018, the paper's main news ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viaduct
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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
