List Of Tunnels In The United Kingdom
This is a list of road, railway, waterway, and other tunnels in the United Kingdom. A tunnel is an underground passageway with no defined minimum length, though it may be considered to be at least twice as long as wide. Some government bodies define a tunnel as in length or longer. A tunnel may be for pedestrians or cyclists, for general road traffic, for motor vehicles only, for rail traffic, or for a canal. Some are aqueducts, constructed purely for carrying water—for consumption, for hydroelectric purposes or as sewers—while others carry other services such as telecommunications cables. There are even tunnels designed as wildlife crossings for European badgers and other endangered species. The longest tunnel in the United Kingdom is the Northern line at . This will be superseded in 2021 by the Woodsmith Mine Tunnel in North Yorkshire that will transport polyhalite from North Yorkshire to a port on Teesside. Standedge Tunnel at is the longest canal tunnel in the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wildlife Crossing
Wildlife crossings are structures that allow animals to cross human-made barriers safely. Wildlife crossings may include underpass tunnels or wildlife tunnels, viaducts, and overpasses or green bridges (mainly for large or herd-type animals); amphibian tunnels; fish ladders; canopy bridges (especially for monkeys and squirrels); tunnels and culverts (for small mammals such as otters, hedgehogs, and badgers); and green roofs (for butterflies and birds). Wildlife crossings are a practice in habitat conservation, allowing connections or reconnections between habitats, combating habitat fragmentation. They also assist in avoiding collisions between vehicles and animals, which in addition to killing or injuring wildlife may cause injury to humans and property damage. Similar structures can be used for domesticated animals, such as cattle creeps. Roads and habitat fragmentation Habitat fragmentation occurs when human-made barriers such as roads, railroads, canals, electric ...

Bedford
Bedford is a market town in Bedfordshire, England. At the 2011 Census, the population of the Bedford built-up area (including Biddenham and Kempston) was 106,940, making it the second-largest settlement in Bedfordshire, behind Luton, whilst the Borough of Bedford had a population of 157,479. Bedford is also the historic county town of Bedfordshire. Bedford was founded at a ford on the River Great Ouse and is thought to have been the burial place of King Offa of Mercia, who is remembered for building Offa's Dyke on the Welsh border. Bedford Castle was built by Henry I of England, Henry I, although it was destroyed in 1224. Bedford was granted borough status in 1165 and has been represented in Parliament since 1265. It is known for its large Italians in the United Kingdom, population of Italian descent. History The name of the town is believed to derive from the name of a Saxon chief called Beda, and a Ford (crossing), ford crossing the River Great Ouse. Bedford was a marke ...

Old Warden Tunnel
Old Warden Tunnel is an abandoned railway tunnel near the village of Old Warden in Bedfordshire. History The tunnel was built as part of the Midland Railway connecting Bedford and Hitchin, and from there to London between 1853 and 1857. Contrary to popular belief the line lost its passenger services before the cuts of Dr. Beeching, they were withdrawn on 1 January 1962 along with goods services between Hitchin and Shefford. Goods services between Shefford and Bedford succumbed to the Beeching Axe on 28 December 1964. Built of blue engineering bricks, the tunnel is ovoid in shape and runs at a very slight gradient to allow drainage; however, it is perfectly straight. The tunnel has no blast relief ducts, due to its lack of curves and relatively short length, allowing good air passage. Regular niches were cut into the wall to allow maintenance on the permanent way during running hours. Finally, both portals were capped with stone and it covers a total length of . This was also ...

Linslade Tunnel
Linslade Tunnel is a railway tunnel in Bedfordshire, England, on the West Coast Main Line about north of Leighton Buzzard railway station and built under Linslade Woods. Consisting of three individual bores, the tunnel is somewhat unusual as there is a slight bend in its alignment. The first bore was constructed during the 1830s, the engineering of which having been performed by the pioneering railway builder George Stephenson. The only of the three bores to accommodate double track, it was first opened to traffic during 1837. During 1857, the eastern bore was opened to serve a branch line from Leighton Buzzard to Dunstable; this has since been closed. In 1876, the western bore was completed, being noticeably narrower than its predecessors. During the 1960s, Linslade Tunnel was outfitted with overhead electrification as part of a wider scheme to introduce electric traction on the West Coast Main Line. In the 1970s, the tunnel portals on either side of the tunnel were recognise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ampthill Tunnel
Ampthill tunnel is a railway tunnel at Ampthill on the Midland Main Line, being positioned between Bedford and Flitwick. It consists of two separate bores, each one accommodating double-track throughout. The first Ampthill Tunnel was built during the 1860s; growing demand on the line led to the original double-track configuration being inadequate for further growth. Thus, during the 1890s, a second Ampthill Tunnel was constructed directly alongside, facilitating the Midland Railway's expansion plans of running a quadruple-track arrangement between Kettering and London wherever practical to do so. Both bores have remained active through to the present day. During mid 2012, Ampthill Tunnel was subject to a series of high speed evaluation runs, including a record maximum speed for the route of ; in the following year, the line speeds were increased to 125 mph along much of the Midland Main Line. History The Ampthill Tunnel was constructed during the early 1860s on behalf of the Mid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standedge Tunnels
The Standedge Tunnels () are four parallel tunnels through the Pennine hills at the Standedge crossing between Marsden in Kirklees, West Yorkshire and Diggle in Oldham, Greater Manchester in northern England. Three are railway tunnels (containing the Huddersfield line) and the other is a canal tunnel. Before boundary changes in 1974, both ends of the tunnels were in the West Riding of Yorkshire. The canal tunnel on the Huddersfield Narrow Canal was authorised by an Act of Parliament on 4 April 1794. Construction of a tunnel began months later. Within two years, cost-saving measures pushed back its completion date and progress was slowed by water levels much greater than had been expected. It proved difficult to secure skilled help, some tenders went unanswered and Benjamin Outram withdrew from the venture. In 1807, Thomas Telford drew up a new plan for its completion. In 1811, the tunnel opened. It is the longest and oldest of the four Standedge tunnels and is the longest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teesside
Teesside () is a built-up area around the River Tees in the north of England, split between County Durham and North Yorkshire. The name was initially used as a county borough in the North Riding of Yorkshire. Historically a hub for heavy manufacturing, the number of people employed in this type of work declined from the 1960s onwards, with steel-making and chemical manufacturing (particularly through Imperial Chemical Industries) replaced to some extent by new science businesses and service sector roles. History 1968–1974: County borough Before the county of Cleveland was created, the area (including Stockton-on-Tees) existed as a part of the North Riding of Yorkshire, due to most land being south of the Tees. Teesside was created due to Stockton-on-Tees being linked heavily with Thornaby (which had amalgamated with South Stockton/Mandale to form the Borough of Thornaby), Middlesbrough and Redcar by industry. Compared to the modern Teesside conurbation, the area was sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyhalite
Polyhalite is an evaporite mineral, a hydrated sulfate of potassium, calcium and magnesium with formula: . Polyhalite crystallizes in the triclinic system, although crystals are very rare. The normal habit is massive to fibrous. It is typically colorless, white to gray, although it may be brick red due to iron oxide inclusions. It has a Mohs hardness of 3.5 and a specific gravity of 2.8. It occurs in sedimentary marine evaporites and is a major potassium ore mineral in the Carlsbad deposits of New Mexico. It is also present as a 2–3% contaminant of Himalayan salt. Polyhalite was first described in 1818 for specimens from its type locality in Salzburg, Austria. The name comes from the German ''Polyhalit'', which comes from the Ancient Greek words (''polys'') and ' (''hals''), which mean "many" and "salt", and the German ending ''-it'' (which comes from the Latin ending -ites, which originally also came from Greek), which is used like the English ending ''-ite'' to form the nam ...

North Yorkshire
North Yorkshire is the largest ceremonial counties of England, ceremonial county (lieutenancy area) in England, covering an area of . Around 40% of the county is covered by National parks of the United Kingdom, national parks, including most of the Yorkshire Dales and the North York Moors. It is one of four counties in England to hold the name Yorkshire; the three other counties are the East Riding of Yorkshire, South Yorkshire and West Yorkshire. North Yorkshire may also refer to a non-metropolitan county, which covers most of the ceremonial county's area () and population (a mid-2016 estimate by the Office for National Statistics, ONS of 602,300), and is administered by North Yorkshire County Council. The non-metropolitan county does not include four areas of the ceremonial county: the City of York, Middlesbrough, Redcar and Cleveland and the southern part of the Borough of Stockton-on-Tees, which are all administered by Unitary authorities of England, unitary authorities. ...

Woodsmith Mine
Woodsmith Mine is a deep potash and polyhalite mine located near to the hamlet of Sneatonthorpe, Whitby in North Yorkshire, England. The venture was started by York Potash Ltd, which became a subsidiary of Sirius Minerals plc whose primary focus is the development of the polyhalite project. The project will mine the world's largest deposit of polyhalite – a naturally occurring mineral. Because the project would require mining to be undertaken in the North York Moors National Park, many objections were raised to the mine and the proposed conveyor that would be installed to transport the raw material offsite to a plant on Teesside away. The mine is expected to have a life of 100 years and has been labelled the biggest mining project in Britain for decades; its twin shafts will be the deepest commercial mineshafts in Britain. The project is expected to generate over £100 billion for the UK economy over a period of 50 years. Once it is functioning it will be the deepest min ...
