Avonmouth Bridge
The Avonmouth Bridge is a road bridge that carries the M5 motorway over the River Avon into Somerset near Bristol, England. The main span is long, and the bridge is long, with an air draught above mean high water level of . It also has a separate footpath and cycleway which connects the B4054 near Avonmouth station with the Royal Portbury Dock and the village of Pill. Construction The bridge was built with three lanes each way, with full hard shoulders. In 1995–2000, it was widened to four lanes each way, with the result that the hard shoulders are no longer of full width. The bridge was built to allow tall ships underneath. This gave the bridge steep gradients that cause heavy vehicles to slow down, resulting in congestion during rush hour and the summer tourist season: traffic can back up both on the bridge and on the approaches. The construction contract was let to Fairfield-Mabey and commenced in 1969; Fairfield-Mabey placed a sub-contract with Tarmac Civil Eng ...

Avonmouth
Avonmouth is a port and outer suburb of Bristol, England, facing two rivers: the reinforced north bank of the final stage of the Avon which rises at sources in Wiltshire, Gloucestershire and Somerset; and the eastern shore of the Severn Estuary. Strategically the area has been and remains an important part of the region's maritime economy particularly for larger vessels for the unloading and exporting of heavier goods as well as in industry including warehousing, light industry, electrical power and sanitation. The area contains a junction of and is connected to the south by the M5 motorway and other roads, railway tracks and paths to the north, south-east and east. The council ward of Avonmouth and Lawrence Weston is as drawn a simplified name as it includes Shirehampton and the western end of Lawrence Weston. Geography Avonmouth is approximately rectangular, its length favouring the Severn shore and sits on the same bank as the city centre from which it lies west-north- ...

Royal Portbury Dock
The Royal Portbury Dock is part of the Port of Bristol, in England. It is situated near the village of Portbury on the southern side of the mouth of the River Avon, Bristol, Avon, where the river joins the Severn estuary — the Avonmouth Docks are on the opposite side of the Avon, within Avonmouth. The deepwater dock was constructed between 1972 and 1977, and is now a major port for the import of motor vehicles into the United Kingdom, UK. The M5 motorway runs nearby, and the huge car storage compounds around the dock are visible from the Avonmouth Bridge. A waste industrial area west of the port is being developed as the Portbury Ashlands Nature Reserve. The Royal Portbury Dock has the largest entrance lock into any UK port, accommodating vessels up to beam, length and draft. Operator The dock is now operated by The Bristol Port Company, which also operates Avonmouth Docks, and has done since 1991 when it purchased a 150-year lease from Bristol City Council. Between ...

Motorway Bridges In England
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway and expressway. Other similar terms include ''wikt:throughway, throughway'' and ''parkway''. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic. In countries following the Vienna Convention on Road Signs and Signals, Vienna convention, the motorway qualification implies that walking and parking are forbidden. A fully controlled-access highway provides an unhindered flow of traffic, with no traffic signals, Intersection (road), intersections or frontage, property access. They are free of any at-grade intersection, at-grade crossings with other roads, railways, or pedestrian paths, which are instead carried by overpasses and underpasses. Entrances and exits to the highway are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges In Bristol
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asphalt
Asphalt, also known as bitumen (, ), is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term asphaltum was also used. Full text at Internet Archive (archive.org) The word is derived from the Ancient Greek ἄσφαλτος ''ásphaltos''. The largest natural deposit of asphalt in the world, estimated to contain 10 million tons, is the Pitch Lake located in La Brea in southwest Trinidad (Antilles island located on the northeastern coast of Venezuela), within the Siparia Regional Corporation. The primary use (70%) of asphalt is in Road surface, road construction, where it is used as the glue or binder mixed with construction aggregate, aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. In material sciences an ...

Tarmac Limited
Tarmac is a British building materials company headquartered in Solihull, England. The company was formed as Lafarge Tarmac in March 2013, by the merger of Anglo American's Tarmac UK and Lafarge's operations in the United Kingdom. In July 2014, Anglo American agreed to sell its stake to Lafarge, to assist Lafarge in its merger with Holcim and allay competition concerns. Prior to 1999, Tarmac Plc was an aggregates to construction company dating from 1903. It was demerged in July 1999, with the Construction and Professional services arms forming Carillion plc. The aggregates and building materials side of the business retained the Tarmac name and was bought by Anglo American shortly afterwards. In February 2015, Lafarge announced that the business would be sold to CRH plc, once Anglo American had sold its stake. Anglo American completed the sale in July 2015, and the acquisition by CRH completed the following month. Following the purchase, Lafarge Tarmac was rebranded as Tarma ...

Mabey Group
The Mabey Group is a British-based group of engineering companies, which specialises in steel fabrication, plant hire and construction products. It was initially established by Guy Mabey as a building supplies business in 1923, and expanded into engineering work, particularly bridging, under the leadership of his son, Bevil Mabey, after World War II. In the early 21st century, it was implicated in bribery scandals over corrupt payments to win contracts in countries including Iraq, Jamaica and Ghana. It sold its bridge business in May 2019 to US-based Acrow Bridge. History Founded by Guy Mabey in 1923, his son Bevil Mabey expanded the company quickly after World War II by buying up spare Bailey bridges from the British Army. Mabey then developed a steel modular bridge package for use as highway structures. His design was lighter, with fewer components, had twice the loading capability, and could be built to longer spans. and with a much longer life. These were extensively deplo ...

Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' of inc ...

Shoulder (road)
A shoulder, hard shoulder (British) or breakdown lane, is an emergency stopping lane by the verge of a road or motorway, on the right side in countries which drive on the right, and on the left side in countries which drive on the left. Many wider (U.S.) freeways, or expressways elsewhere have shoulders on both sides of each directional carriageway — in the median, as well as at the outer edges of the road, for additional safety. Shoulders are not intended for use by through traffic, although there are exceptions. Purpose Shoulders have multiple uses, including: * Emergency vehicles such as ambulances, fire trucks and police cars may use the shoulder to bypass traffic congestion. * In the event of an emergency or breakdown, a motorist can pull into the shoulder to get out of the flow of traffic and obtain a greater degree of safety. * Active traffic management, used on busy multi-lane roads, may allow 'hard shoulder running' by general traffic at reduced speeds during periods ...
