Orwell Bridge
The Orwell Bridge is a concrete box girder bridge just south of Ipswich in Suffolk, England. Opened to road traffic in 1982, the bridge carries the A14 road (formerly the A45) over the River Orwell. History Design The main span is 190 metres which, at the time of its construction, was the longest pre-stressed concrete span in use in the UK. The two spans adjacent to the main span are 106m, known as anchor spans. Most of the other spans are 59m. The total length is 1,287 metres from Wherstead to the site of the former Ipswich Airport. The width is 24 metres with an air draft of 43 metres; the bridge had to be at least 41 metres high. The approach roads were designed by CH Dobbie & Partners of Cardiff, later bought by Babtie, Shaw and Morton then Jacobs in 2004. The bridge is constructed of a pair of continuous concrete box girders with expansion joints that allow for expansion and contraction. The girders are hollow, allowing for easier inspection, as well as providing access f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A14 Road (England)
The A14 is a major trunk road in England, running from Catthorpe Interchange, a major intersection at the southern end of the M6 and junction 19 of the M1 in Leicestershire to the Port of Felixstowe, Suffolk. The road forms part of the unsigned Euroroutes E24 and E30. It is the busiest shipping lane in East Anglia carrying anything from cars to large amounts of cargo between the UK and Mainland Europe. Route Beginning at the Catthorpe Interchange, the A14 runs through Kettering, Northamptonshire towards Huntingdon where it now runs parallel to the A1 past Brampton, Cambridgeshire and now bypasses Huntingdon completely due to the A14 Cambridge to Huntingdon Scheme from 2017 until 2022. It continues past Bar Hill towards Cambridge to meet the end of the M11 and the A428 at the Girton Interchange. The A14 continues easterly over northern Cambridge towards Newmarket where it briefly joins with the A11 to form the Newmarket Bypass between J36 and J38. The A11 splits off again t ...

Air Draft (nautical)
Air draft (or air draught) is the distance from the surface of the water to the highest point on a Marine vessel, vessel. This is similar to the "Draft (hull), deep draft" of a vessel which is measured from the surface of the water to the deepest part of the hull below the surface, but air draft is expressed as a height, not a depth. Clearance below The vessel's "Engineering tolerance#Clearance (civil engineering), clearance" is the distance in excess of the air draft which allows a vessel to pass safely under a bridge or obstacle such as Electric power transmission, power lines, etc. A bridge's "clearance below" is most often noted on charts as measured from the surface of the water to the under side of the bridge at the chart datum Mean High Water (MHW), a less restrictive clearance than Mean Higher High Water (MHHW). In 2014, the United States Coast Guard reported that 1.2% of the collisions it investigated in the recent past were due to vessels attempting to pass underne ...

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 ...

Road-traffic Safety
Road traffic safety refers to the methods and measures used to prevent road users from being killed or seriously injured. Typical road users include pedestrians, cyclists, Driving, motorists, vehicle passengers, horse riders, and passengers of on-road public transport (mainly buses and trams). Best practices in modern road safety strategy: As sustainable solutions for classes of road safety have not been identified, particularly low-traffic rural and remote roads, a hierarchy of control should be applied, similar to classifications used to improve occupational safety and health. At the highest level is sustainable prevention of serious injury and death crashes, with sustainable requiring all key result areas to be considered. At the second level is real-time risk reduction, which involves providing users at severe risk with a specific warning to enable them to take mitigating action. The third level is about reducing the crash risk which involves applying the road-design st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terrain
Terrain or relief (also topographical relief) involves the vertical and horizontal dimensions of land surface. The term bathymetry is used to describe underwater relief, while hypsometry studies terrain relative to sea level. The Latin word (the root of ''terrain'') means "earth." In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns. Importance The understanding of terrain is critical for many reasons: * The terrain of a region largely determines its suitability for human settlement: flatter alluvial plains tend to have better farming soils than steeper, rockier uplands. * In terms of environmental quality, agriculture, hydrology and other interdisciplinary sciences; understanding the terrain of an area assists the understanding of watershed boundaries, dra ...

Port Of Ipswich
The Port of Ipswich can be dated to c.625. The name Ipswich was originally Gippeswyc, referring to the River Gyppes with a suffix derived from the Scandinavian term vik, which had evolved from meaning bay or inlet to mean landing-place, following the proliferation of merchants requiring places to unload their goods and conduct trade. Since 1997 the port has been run by Associated British Ports. History Early Middle Ages, 7th century to 1066 The Port of Ipswich emerged in the Early Middle Ages. A wharf was in operation in Ipswich on a bend in the River Orwell in the 8th century, and was probably established during the 7th century under the protection of the Wuffingas, the ruling house of the Kingdom of East Anglia. Steven Plunkett has suggested that the founding of Gipeswic was associated with the reign of Rædwald (died c.624) and that it reflected his personal importance during the period of his supremacy. The importance of this wharf, and the town which grew up around it, has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Looking West - Geograph
Looking is the act of intentionally focusing visual perception on someone or something, for the purpose of obtaining information, and possibly to convey interest or another sentiment. A large number of troponyms exist to describe variations of looking at things, with prominent examples including the verbs "stare, gaze, gape, gawp, gawk, goggle, glare, glimpse, glance, peek, peep, peer, squint, leer, gloat, and ogle".Anne Poch Higueras and Isabel Verdaguer Clavera, "The rise of new meanings: A historical journey through English ways of ''looking at''", in Javier E.

Alton Water
Alton Water (or Alton Reservoir) is a manmade reservoir located on the Shotley peninsula. It is the largest in Suffolk, with a perimeter of over . Construction Due to a shortage of water in the Ipswich area in the 1960s, a list of twenty potential sites for reservoirs was made, with Alton being the chosen site. The land was mainly farmland, but was also home to a mill and Alton Hall. The mill was dismantled and reconstructed at the Museum of East Anglian Life in Stowmarket. Construction and the filling with water took 13 years to complete. Alton Reservoir was opened in 1987 and is fed from the River Gipping and bore holes on the north side of the River Orwell. The pumping station and treatment works below the dam is capable of treating up to of water a day. Between 85% and 95% of the water goes to Ipswich and Felixstowe via the Wherstead reservoir and the Orwell Bridge with the remainder fed to the villages of the Shotley Peninsula and south Suffolk.

Thermal Expansion
Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, molecules begin to vibrate and move more, usually creating more distance between themselves. Substances which contract with increasing temperature are unusual, and only occur within limited temperature ranges (see examples below). The relative expansion (also called strain) divided by the change in temperature is called the material's coefficient of linear thermal expansion and generally varies with temperature. As energy in particles increases, they start moving faster and faster weakening the intermolecular forces between them, therefore expanding the substance. Overview Predicting expansion If an equation of state is available, it can be used to predict the values of the thermal expan ...

Expansion Joint
An expansion joint, or movement joint, is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials, and vibration, or to allow movement due to ground settlement or seismic activity. They are commonly found between sections of buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures. Building faces, concrete slabs, and pipelines expand and contract due to warming and cooling from seasonal variation, or due to other heat sources. Before expansion joint gaps were built into these structures, they would crack under the stress induced. Bridge expansion joints Bridge expansion joints are designed to allow for continuous traffic between structures while accommodating movement, shrinkage, and temperature variations on reinforced and prestressed concrete, composite, and steel structures. They stop the bridge from bending out of place in extreme conditions, and also allow eno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Charles Ingli ...
