The United Kingdom the United Kingdom of Great Britain and Northern Ireland, sometimes referred to as Britain, is a sovereign country located off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state, the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world; the Irish Sea lies between Great Ireland. With an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world, it is the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017. The UK is constitutional monarchy; the current monarch is Queen Elizabeth II, who has reigned since 1952, making her the longest-serving current head of state.
The United Kingdom's capital and largest city is London, a global city and financial centre with an urban area population of 10.3 million. Other major urban areas in the UK include Greater Manchester, the West Midlands and West Yorkshire conurbations, Greater Glasgow and the Liverpool Built-up Area; the United Kingdom consists of four constituent countries: England, Scotland and Northern Ireland. Their capitals are London, Edinburgh and Belfast, respectively. Apart from England, the countries have their own devolved governments, each with varying powers, but such power is delegated by the Parliament of the United Kingdom, which may enact laws unilaterally altering or abolishing devolution; the nearby Isle of Man, Bailiwick of Guernsey and Bailiwick of Jersey are not part of the UK, being Crown dependencies with the British Government responsible for defence and international representation. The medieval conquest and subsequent annexation of Wales by the Kingdom of England, followed by the union between England and Scotland in 1707 to form the Kingdom of Great Britain, the union in 1801 of Great Britain with the Kingdom of Ireland created the United Kingdom of Great Britain and Ireland.
Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain and Northern Ireland. There are fourteen British Overseas Territories, the remnants of the British Empire which, at its height in the 1920s, encompassed a quarter of the world's land mass and was the largest empire in history. British influence can be observed in the language and political systems of many of its former colonies; the United Kingdom is a developed country and has the world's fifth-largest economy by nominal GDP and ninth-largest economy by purchasing power parity. It has a high-income economy and has a high Human Development Index rating, ranking 14th in the world, it was the world's first industrialised country and the world's foremost power during the 19th and early 20th centuries. The UK remains a great power, with considerable economic, military and political influence internationally, it is sixth in military expenditure in the world. It has been a permanent member of the United Nations Security Council since its first session in 1946.
It has been a leading member state of the European Union and its predecessor, the European Economic Community, since 1973. The United Kingdom is a member of the Commonwealth of Nations, the Council of Europe, the G7, the G20, NATO, the Organisation for Economic Co-operation and Development and the World Trade Organization; the 1707 Acts of Union declared that the kingdoms of England and Scotland were "United into One Kingdom by the Name of Great Britain". The term "United Kingdom" has been used as a description for the former kingdom of Great Britain, although its official name from 1707 to 1800 was "Great Britain"; the Acts of Union 1800 united the kingdom of Great Britain and the kingdom of Ireland in 1801, forming the United Kingdom of Great Britain and Ireland. Following the partition of Ireland and the independence of the Irish Free State in 1922, which left Northern Ireland as the only part of the island of Ireland within the United Kingdom, the name was changed to the "United Kingdom of Great Britain and Northern Ireland".
Although the United Kingdom is a sovereign country, Scotland and Northern Ireland are widely referred to as countries. The UK Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom; some statistical summaries, such as those for the twelve NUTS 1 regions of the United Kingdom refer to Scotland and Northern Ireland as "regions". Northern Ireland is referred to as a "province". With regard to Northern Ireland, the descriptive name used "can be controversial, with the choice revealing one's political preferences"; the term "Great Britain" conventionally refers to the island of Great Britain, or politically to England and Wales in combination. However, it is sometimes used as a loose synonym for the United Kingdom as a whole; the term "Britain" is used both as a synonym for Great Britain, as a synonym for the United Kingdom. Usage is mixed, with the BBC preferring to use Britain as shorthand only for Great Britain and the UK Government, while accepting that both terms refer to the United K
Norfolk is a county in East Anglia in England. It borders Lincolnshire to the northwest, Cambridgeshire to the west and southwest, Suffolk to the south, its northern and eastern boundaries are the North Sea and, to the north-west, The Wash. The county town is Norwich. With an area of 2,074 square miles and a population of 859,400, Norfolk is a rural county with a population density of 401 per square mile. Of the county's population, 40% live in four major built up areas: Norwich, Great Yarmouth, King's Lynn and Thetford; the Broads is a network of lakes in the east of the county, extending south into Suffolk. The area is not a national park, it has similar status to a national park, is protected by the Broads Authority. Norfolk was settled in pre-Roman times, with camps along the higher land in the west, where flints could be quarried. A Brythonic tribe, the Iceni, inhabited the county from the 1st century BC to the end of the 1st century AD; the Iceni revolted against the Roman invasion in AD 47, again in 60 led by Boudica.
The crushing of the second rebellion opened the county to the Romans. During the Roman era roads and ports were constructed throughout the county and farming was widespread. Situated on the east coast, Norfolk was vulnerable to invasions from Scandinavia and Northern Europe, forts were built to defend against the Angles and Saxons. By the 5th century the Angles, after whom East Anglia and England itself are named, had established control of the region and became the "north folk" and the "south folk", hence, "Norfolk" and "Suffolk". Norfolk and several adjacent areas became the kingdom of East Anglia, which merged with Mercia and with Wessex; the influence of the Early English settlers can be seen in the many place names ending in "-ton" and "-ham". Endings such as "-by" and "-thorpe" are common, indicating Danish place names: in the 9th century the region again came under attack, this time from Danes who killed the king, Edmund the Martyr. In the centuries before the Norman Conquest the wetlands of the east of the county began to be converted to farmland, settlements grew in these areas.
Migration into East Anglia must have been high: by the time of the Domesday Book survey it was one of the most densely populated parts of the British Isles. During the high and late Middle Ages the county developed arable woollen industries. Norfolk's prosperity at that time is evident from the county's large number of medieval churches: out of an original total of over one thousand, 659 have survived, more than in the whole of the rest of Great Britain; the economy was in decline by the time of the Black Death, which reduced the population in 1349. By the 16th century Norwich had grown to become the second-largest city in England, but over one-third of its population died in the plague epidemic of 1579, in 1665 the Great Plague again killed around one-third of the population. During the English Civil War Norfolk was Parliamentarian; the economy and agriculture of the region declined somewhat. During the Industrial Revolution Norfolk developed little industry except in Norwich, a late addition to the railway network.
In the 20th century the county developed a role in aviation. The first development in airfields came with the First World War. For the local army regiments the Royal Norfolk Regiment and the Norfolk Yeomanry please click on the links. During the Second World War agriculture intensified, it has remained intensive since, with the establishment of large fields for growing cereals and oilseed rape. Norfolk's low-lying land and eroded cliffs, many of which are composed of chalk and clay, make it vulnerable to weathering by the sea; the most recent major erosion event occurred during the North Sea flood of 1953. The low-lying section of coast between Kelling and Lowestoft Ness in Suffolk is managed by the British Environment Agency to protect the Broads from sea flooding. Management policy for the North Norfolk coastline is described in the "North Norfolk Shoreline Management Plan" published in 2006, but has yet to be accepted by local authorities; the Shoreline Management Plan states that the stretch of coast will be protected for at least another 50 years, but that in the face of sea level rise and post-glacial lowering of land levels in the South East, there is an urgent need for further research to inform future management decisions, including the possibility that the sea defences may have to be realigned to a more sustainable position.
Natural England have contributed some research into the impacts on the environment of various realignment options. The draft report of their research was leaked to the press, who created great anxiety by reporting that Natural England plan to abandon a large section of the Norfolk Broads and farmland to the sea to save the rest of the Norfolk coastline from the impact of climate change. In 1998 Norfolk had a Gross Domestic Product of £9,319 million, which represents 1.5% of England's economy and 1.25% of the United Kingdom's economy. The GDP per head was £11,825, compared to £13,635 for East Anglia, £12,845 for England and £12,438 for the United Kingdom. In 1999–2000 the county had an unemployment rate of 5.6%, compared to 5.8% for England and 6.0% for the UK. Data from 2017 provided a useful update on the county's economy; the median hourly gross pay was £12.17 and the median weekly pay was £496.80. The employm
The Waveney is a river which forms the boundary between Suffolk and Norfolk, for much of its length within the Broads. The source of the River Waveney is a ditch on the east side of the B1113 road between the villages of Redgrave and South Lopham, Norfolk; the ditch on the other side of the road is the source of the River Little Ouse which continues the county boundary and, via the Great Ouse, reaches the sea at King's Lynn. It is thus claimed; the explanation of this oddity is that the valley in which the rivers rise was formed not by these rivers, but by water spilling from the periglacial lake known as Lake Fenland. This was a periglacial lake of fifteen or twenty thousand years ago; the ice sheet closed the natural drainage from the Vale of Pickering, the Humber and The Wash so that a lake of a complex shape formed in the Vale of Pickering, the Yorkshire Ouse valley, the lower Trent valley and the Fenland basin. This valley was its spillway into the southern North Sea basin, thence to the English Channel basin.
The river rises close to the 82-foot contour, flows in an easterly direction though the towns of Diss and Beccles. From its source it forms the southern boundary of Roydon before it reaches Diss. At Scole it is crossed with the modern A140 bypass just to the east. There is a weir at Billingford and Billingford Windmill is situated a little to the north of the river. Beyond Billingford Bridge the River Dove, flowing northwards from Eye, joins on the southern bank, the Mid Suffolk Footpath crosses and the river drops below the 66-foot contour at another weir, it turns to the north-east to reach Needham before passing to the south of Harleston. There are several lakes on the south bank, the largest covering 100 acres, which were once Weybread Gravel Pits, but are now used for fishing. Below the lakes are the remains of a Cluniac priory and the extensive drained area of Mendham Marshes. Mendham, the birthplace of the artist Alfred Munnings, lies on the Suffolk bank, Wortwell is in Norfolk, Homersfield is again in Suffolk.
In 1869, Homersfield Bridge, one of the first bridges to be constructed from concrete and iron was built across the river here. It was commissioned by Sir Shafto Adair, had a span of 50 feet and predated the introduction of true reinforced concrete by several years, it is a Grade II * listed structure. Road traffic was diverted onto a new bridge in 1970 and it was acquired by Norfolk County Council in 1994, they passed it on to the Norfolk Historic Buildings Trust, who managed its restoration in 1995, funded by grants from English Heritage, Blue Circle Industries and councils at county and local level. At Earsham the Otter Trust had one of its three UK centres, which opened in 1978 and closed in 2006, having boosted otter numbers on the river. At Bungay, the historic head of navigation, the Waveney forms a wide oxbow meander, carrying with it the Norfolk/Suffolk border. Next come Ditchingham and Ellingham before Geldeston, where an isolated pub stands next to the site of a lock, now replaced by a sluice.
This is the current limit of navigation for craft larger than a rowing or paddling boat and at this point the Waveney becomes a tidal river. A short way further along is a dyke. Gillingham comes. Although the old town bridge here restricts navigation to craft with an airdraft of less than 6 feet 6 inches, its quay beyond that abruptly changes the nature of the river from a gentle rural feature to a gateway to the North Sea. Beccles was a fishing port for many years and the parents of Lord Nelson were married in the church of St Michael; the river meanders past Barnby Broad and Marshes SSSI and Burgh St Peter to Somerleyton. Here Oulton Dyke branches off the Waveney to Oulton Broad towards Lowestoft. A sea lock, known as Mutford Lock, divides fresh from seawater and links Oulton Broad with Lake Lothing and the North Sea; this lock will allow traffic to pass through. At Somerleyton the Lowestoft to Norwich railway line crosses the Waveney on a swing bridge, while at St Olaves, the Haddiscoe Cut branches off left to connect the Rivers Yare and Waveney.
The Cut was excavated in the 19th century to provide a direct route between Lowestoft Docks and Norwich. The Waveney flows past Burgh Castle into Breydon Water at the confluence of the two rivers, it now reaches the sea at Great Yarmouth. There was a special version of the Norfolk wherry in use on the Waveney, with boats measuring no more than 70 by 16 feet. There were steam wherries. Daniel Defoe enlivens this account of the Waveney's Broads course:The River Waveney is a considerable river, of a deep and full channel, navigable for large barges as high as Beccles.
Norwich is a historic city in Norfolk, England. Situated on the River Wensum in East Anglia, it lies 100 miles north-east of London, it is the county town of Norfolk and is considered the capital of East Anglia, with a population of 141,300. From the Middle Ages until the Industrial Revolution, Norwich was the largest city in England after London, one of the most important; the city is the most complete medieval city in the UK, including cobbled streets such as Elm Hill, Timber Hill and Tombland, ancient buildings such as St Andrew's Hall, half-timbered houses such as Dragon Hall, The Guildhall and Strangers' Hall, the Art Nouveau of the 1899 Royal Arcade, many medieval lanes and the winding River Wensum that flows through the city centre towards Norwich Castle. The city has two universities, the University of East Anglia and the Norwich University of the Arts, two cathedrals, Norwich Cathedral and St John the Baptist Cathedral. Norwich is the only city containing part of a National Park, the Norfolk Broads, it holds the largest permanent undercover market in Europe.
The urban area of Norwich had a population of 213,166 according to the 2011 Census. The parliamentary seats cross over into adjacent local-government districts. A total of 132,512 people live in the City of Norwich and the population of the Norwich Travel to Work Area is 282,000. Norwich is the fourth most densely populated local-government district in the East of England, with 3,480 people per square kilometre. In May 2012, Norwich was designated England's first UNESCO City of Literature. One of the UK's most popular tourist destinations, it was voted by The Guardian in 2016 as the "happiest city to work in the UK" and in 2013 as one of the best small cities in the world by The Times Good University Guide. In 2018, Norwich was voted one of the "Best Places To Live" in the UK by The Sunday Times; the capital of the Iceni tribe was a settlement located near to the village of Caistor St. Edmund on the River Tas 8 kilometres to the south of modern-day Norwich. Following an uprising led by Boudica around AD 60 the Caistor area became the Roman capital of East Anglia named Venta Icenorum "the marketplace of the Iceni".
The Roman settlement fell into disuse around 450 and the Anglo-Saxons settled on the site of the modern city between the 5th and 7th centuries, founding the towns of Northwic and the secondary settlement at Thorpe. According to a local rhyme, the demise of Venta Icenorum led to the development of Norwich: "Caistor was a city when Norwich was none, Norwich was built of Caistor stone." There are two suggested models of development for Norwich. It is possible that three separate early Anglo-Saxon settlements, one on the north of the river and two either side on the south, joined together as they grew or that one Anglo-Saxon settlement, on the north of the river, emerged in the mid-7th century after the abandonment of the previous three; the ancient city was a thriving centre for trade and commerce in East Anglia in 1004 when it was raided and burnt by Swein Forkbeard the Viking king of Denmark. Mercian coins and shards of pottery from the Rhineland dating from the 8th century suggest that long-distance trade was happening long before this.
Between 924 and 939, Norwich became established as a town, with its own mint. The word Norvic appears on coins across Europe minted during this period, in the reign of King Athelstan; the Vikings were a strong cultural influence in Norwich for 40 to 50 years at the end of the 9th century, setting up an Anglo-Scandinavian district near the north end of present day King Street. At the time of the Norman Conquest the city was one of the largest in England; the Domesday Book states that it had 25 churches and a population of between 5,000 and 10,000. It records the site of an Anglo-Saxon church in Tombland, the site of the Saxon market place and the Norman cathedral. Norwich continued to be a major centre for trade, the River Wensum being a convenient export route to the River Yare and Great Yarmouth, which served as the port for Norwich. Quern stones and other artefacts from Scandinavia and the Rhineland have been found during excavations in Norwich city centre; these date from the 11th century onwards.
Norwich Castle was founded soon after the Norman Conquest. The Domesday Book records; the Normans established a new focus of settlement around the Castle and the area to the west of it: this became known as the "New" or "French" borough, centred on the Normans' own market place which survives to the present day as Norwich Market. In 1096, Herbert de Losinga, Bishop of Thetford, began construction of Norwich Cathedral; the chief building material for the Cathedral was limestone. To transport the building stone to the site, a canal was cut from the river, all the way up to the east wall. Herbert de Losinga moved his See there to what became the cathedral church for the Diocese of Norwich; the Bishop of Norwich still signs himself Norvic. Norwich received a royal charter from Henry II in 1158, another one from Richard the Lionheart in 1194. Following a riot in the city in 1274, Norwich has the distinction of being the only complete English city to be excommunicated by the Pope; the first recorded presence of Jews in Norwich is 1134.
In 1144, the Jews of Norwich were accused of ritual murder after a boy was found dead with stab wounds. William acquired the status of martyr
In England, a civil parish is a type of administrative parish used for local government, they are a territorial designation, the lowest tier of local government below districts and counties, or their combined form, the unitary authority. Civil parishes can trace their origin to the ancient system of ecclesiastical parishes which played a role in both civil and ecclesiastical administration; the unit rolled out across England in the 1860s. A civil parish can range in size from a large town with a population of about 75,000 to a single village with fewer than a hundred inhabitants. Eight parishes have city status. A civil parish may be known as and confirmed as a town, neighbourhood or community by resolution of its parish council, a right reserved not conferred on other units of English local government. 35% of the English population live in a civil parish. As of 31 December 2015 there were 10,449 parishes in England; the most populous is Weston super Mare and those with cathedral city status are Chichester, Hereford, Ripon, Salisbury and Wells.
On 1 April 2014, Queen's Park became the first civil parish in Greater London. Before 2008 their creation was not permitted within a London borough. Wales was divided into civil parishes until 1974, when they were replaced by communities, which are similar to English parishes in the way they operate. Civil parishes in Scotland were abolished for local government purposes by the Local Government Act 1929, the Scottish equivalent of English civil parishes are community council areas, which were established by the Local Government Act 1973; the Parish system in Europe was established between the 8th and 12th centuries and in England was old by the time of the Conquest. These areas were based on the territory of one or more manors, areas which in some cases derived their bounds from Roman or Iron Age estates. Parish boundaries were conservative, changing little, after 1180'froze' so that boundaries could no longer be changed at all, despite changes to manorial landholdings - though there were some examples of sub-division.
The consistency of these boundaries, up until the 19th century is useful to historians, is of cultural significance in terms of shaping local identities, a factor reinforced by the adoption of parish boundaries unchanged, by successor local government units. There was huge variation in size between parishes, for instance Writtle in Essex was 13,568 acres while neighbouring Shellow Bowells was just 469 acres, Chignall Smealy 476 acres; until the break with Rome, parishes managed ecclesiastical matters, while the manor was the principal unit of local administration and justice. The church replaced the manor court as the rural administrative centre, levied a local tax on produce known as a tithe. In the medieval period, responsibilities such as relief of the poor passed from the Lord of the Manor to the parish's rector, who in practice would delegate tasks among his vestry or the monasteries. After the dissolution of the monasteries, the power to levy a rate to fund relief of the poor was conferred on the parish authorities by the Act for the Relief of the Poor 1601.
Both before and after this optional social change, local charities are well-documented. The parish authorities were consisted of all the ratepayers of the parish; as the number of ratepayers of some parishes grew, it became difficult to convene meetings as an open vestry. In some built up, areas the select vestry took over responsibility from the entire body of ratepayers; this innovation allowed governance by a self-perpetuating elite. The administration of the parish system relied on the monopoly of the established English Church, which for a few years after Henry VIII alternated between the Roman Catholic Church and the Church of England, before settling on the latter on the accession of Elizabeth I in 1558. By the 18th century, religious membership was becoming more fractured in some places, due for instance to the progress of Methodism; the legitimacy of the parish vestry came into question and the perceived inefficiency and corruption inherent in the system became a source for concern in some places.
For this reason, during the early 19th century the parish progressively lost its powers to ad hoc boards and other organisations, for example the loss of responsibility for poor relief through the Poor Law Amendment Act 1834. Sanitary districts covered England in Ireland three years later; the replacement boards were each entitled to levy their own rate in the parish. The church rate ceased to be levied in many parishes and became voluntary from 1868; the ancient parishes diverged into two distinct, nearly overlapping, systems of parishes during the 19th century. The Poor Law Amendment Act 1866 declared all areas that levied a separate rate: C of E ecclesiastical parishes, extra-parochial areas and their analogue, chapelries, to be "civil parishes". To have collected rates this means these beforehand had their own vestries, boards or equivalent bodies; the Church of England parishes, which cover more than 99% of England, became termed "ecclesiastical parishes" and the boundaries of these soon diverged from those of the Ancient Parishes in order to reflect modern circumstances.
After 1921 each ecclesiastical parish has been the responsibility of the parochial church councils. In the late 19th century, most of the ancient irregularities inheri
A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world; this type of bridge has cables suspended between towers, plus vertical suspender cables that carry the weight of the deck below, upon which traffic crosses. This arrangement allows the deck to arc upward for additional clearance. Like other suspension bridge types, this type is constructed without falsework; the suspension cables must be anchored at each end of the bridge, since any load applied to the bridge is transformed into a tension in these main cables. The main cables continue beyond the pillars to deck-level supports, further continue to connections with anchors in the ground; the roadway is supported by called hangers. In some circumstances, the towers may sit on a bluff or canyon edge where the road may proceed directly to the main span, otherwise the bridge will have two smaller spans, running between either pair of pillars and the highway, which may be supported by suspender cables or may use a truss bridge to make this connection.
In the latter case there will be little arc in the outboard main cables. The earliest suspension bridges were ropes slung across a chasm, with a deck at the same level or hung below the ropes such that the rope had a catenary shape; the Tibetan saint and bridge-builder Thangtong Gyalpo originated the use of iron chains in his version of simple suspension bridges. In 1433, Gyalpo built eight bridges in eastern Bhutan; the last surviving chain-linked bridge of Gyalpo's was the Thangtong Gyalpo Bridge in Duksum en route to Trashi Yangtse, washed away in 2004. Gyalpo's iron chain bridges did not include a suspended deck bridge, the standard on all modern suspension bridges today. Instead, both the railing and the walking layer of Gyalpo's bridges used wires; the stress points. Before the use of iron chains it is thought that Gyalpo used ropes from twisted willows or yak skins, he may have used bound cloth. The first iron chain suspension bridge in the Western world was the Jacob's Creek Bridge in Westmoreland County, designed by inventor James Finley.
Finley's bridge was the first to incorporate all of the necessary components of a modern suspension bridge, including a suspended deck which hung by trusses. Finley patented his design in 1808, published it in the Philadelphia journal, The Port Folio, in 1810. Early British chain bridges included the Dryburgh Abbey Bridge and 137 m Union Bridge, with spans increasing to 176 m with the Menai Bridge, "the first important modern suspension bridge"; the first chain bridge on the German speaking territories was the Chain Bridge in Nuremberg. The Clifton Suspension Bridge is one of the longest of the parabolic arc chain type; the current Marlow suspension bridge was designed by William Tierney Clark and was built between 1829 and 1832, replacing a wooden bridge further downstream which collapsed in 1828. It is the only suspension bridge across the non-tidal Thames; the Széchenyi Chain Bridge, spanning the River Danube in Budapest, was designed by William Clark and it is a larger scale version of Marlow bridge.
An interesting variation is Thornewill and Warham's Ferry Bridge in Burton-on-Trent, where the chains are not attached to abutments as is usual, but instead are attached to the main girders, which are thus in compression. Here, the chains are made from flat wrought iron plates, eight inches wide by an inch and a half thick, rivetted together; the first wire-cable suspension bridge was the Spider Bridge at Falls of Schuylkill, a modest and temporary footbridge built following the collapse of James Finley's nearby Chain Bridge at Falls of Schuylkill. The footbridge's span was 124 m. Development of wire-cable suspension bridges dates to the temporary simple suspension bridge at Annonay built by Marc Seguin and his brothers in 1822, it spanned only 18 m. The first permanent wire cable suspension bridge was Guillaume Henri Dufour's Saint Antoine Bridge in Geneva of 1823, with two 40 m spans; the first with cables assembled in mid-air in the modern method was Joseph Chaley's Grand Pont Suspendu in Fribourg, in 1834.
In the United States, the first major wire-cable suspension bridge was the Wire Bridge at Fairmount in Philadelphia, Pennsylvania. Designed by Charles Ellet, Jr. and completed in 1842, it had a span of 109 m. Ellet's Niagara Falls Suspension Bridge was abandoned before completion, it was used as scaffolding for John A. Roebling's double decker railroad and carriage bridge; the Otto Beit Bridge was the first modern suspension bridge outside the United States built with parallel wire cables. The main forces in a suspension bridge of any type are tension in the cables and compression in the pillars. Since all the force on the pillars is vertically downwards and they are stabilized by the main cables, the pillars can be made quite slender, as on the Severn Bridge, on the Wales-England border. In a suspended deck bridge, cables suspended via towers hold up the road deck; the weight is transferred by the cables to the towers, which in turn transfer the weight to the ground. Assuming a negligible weight as compared to the weight of the deck and vehicles being supported, the main cables of a suspension bridge will form a parabola (very similar
The Wherry Lines are railway branch lines in the East of England, linking Norwich to Great Yarmouth and Lowestoft. There are 14 stations including the three termini, they are classified as a rural line. The lines pass through the Broads of Suffolk; the name is taken from the Norfolk wherries, which played an important role in the transport of goods and people around the Broads before road and rail transport became widespread. Passenger services on the Wherry Lines are operated by Abellio Greater Anglia; the route was opened from Norwich to Great Yarmouth by the Norwich and Yarmouth Railway in 1844, running via Reedham. The line from Reedham to Lowestoft was added in 1847 by Samuel Morton Peto as part of the Norfolk Railway; the northern route from Norwich to Great Yarmouth via Acle was added in 1883 by the Great Eastern Railway, opening from Breydon Junction to Acle on 12 March, through to Brundall on 1 June. In 2007 the services operating on the line were designated as community rail services as part of the Community Rail Development Strategy aiming to increase patronage and income, improve cost control and develop a greater sense of community involvement.
The line from Norwich to Lowestoft is double-track throughout, but the two Great Yarmouth branches that diverge from Brundall via Acle and from Reedham via Berney Arms are single-track. The Wherry Lines are not electrified, hence services are formed by diesel multiple units; the route has a loading gauge of W8, except between Lowestoft and Oulton Broad North where it is W6, a maximum line speed of 60 miles per hour. Of the 14 stations, two are request stops: Berney Arms, which sees four trains call per day, Buckenham, which has no weekday service but sees three trains call on Saturdays and six trains each Sunday. At most of the stations on the Wherry Lines, service frequencies are increased during the summer months; the signalling system is due to be modernised in 2018-19. The line between Reedham and Great Yarmouth will be closed from 20 October 2018 until April 2019. Network Rail have stated. In January 2019, it was reported that the project was overrunning and that the line between Reedham and Great Yarmouth would not reopen in April 2019 as scheduled.
No firm date was given as to. Passenger services are operated by Abellio Greater Anglia using Class 153 "Super Sprinter", Class 156 "Super Sprinter" or Class 170 "Turbostar" diesel trains. In 2015 the train operator introduced DRS Class 37 locomotive-hauled services due to a shortage of rolling stock as the route is not electrified. On Mondays to Saturdays, one service in each direction between Norwich and Lowestoft is served by East Midlands Trains Class 158 Express Sprinter units, operated by Greater Anglia; the service runs in the early morning on both journeys. Nearly all services on the line run to and from Norwich; some summer Saturday services were extended to and from London Liverpool Street via Norwich which ran to and from Great Yarmouth. These services were formed of British Rail Class 90 electric locomotives with Mark 3 Coaching Stock, which were hauled from Norwich by a British Rail Class 47 diesel locomotive; the services have now ceased favouring connections with existing local services, due to the complexity of the coupling and uncoupling and other issues which led to poor reliability of the mainline operation.
