Holt Bridge
Holt Fleet Bridge, also known as Holt Bridge, is a cast-iron arch bridge over the River Severn, at Holt in Worcestershire, England. It has a span of ; it was designed by Thomas Telford and opened in 1828. It is Grade II listed, and is similar to Telford's Galton Bridge, which is a Grade I listed structure that spans his BCN New Main Line canal at Smethwick. The bridge was built with five cast-iron ribs, with X-braced spandrels, as were several of Telford's bridges. It was strengthened in 1928. when the upper and lower parts of each rib and some of the diagonal struts above them were encased in concrete. The road deck was rebuilt in reinforced concrete and widened at the same time. Semicircular arches at each end, built in red sandstone, allow for the passage of riverbank foot-traffic and floodwater.

Smethwick
Smethwick () is an industrial town in Sandwell, West Midlands, England. It lies west of Birmingham city centre. Historically it was in Staffordshire. In 2019, the ward of Smethwick had an estimated population of 15,246, while the wider built-up area subdivision has a population of 53,653. History It was suggested that the name Smethwick meant "smiths' place of work", but a more recent interpretation has suggested the name means "the settlement on the smooth land". Smethwick was recorded in the Domesday Book as ''Smedeuuich'', the ''d'' in this spelling being the Anglo-Saxon letter eth. Until the end of the 18th century it was an outlying hamlet of the south Staffordshire village of Harborne. Harborne became part of the county borough of Birmingham and thus transferred from Staffordshire to Warwickshire in 1891, leaving Smethwick in the County of Staffordshire. The world's oldest working engine, the Smethwick Engine, made by Boulton & Watt, originally stood near ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges Completed In 1828
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Crossings Of The River Severn
This is a list of crossings of the River Severn in Great Britain (including bridges, tunnels, ferries and fords), in order from source to mouth. The Severn has historically been a very important and busy river, and has been bridged throughout history. The bridges that stand today are often of great historical and/or engineering interest. For example, the world's first iron bridge, The Iron Bridge, built from cast iron, crosses the River Severn at Ironbridge Gorge. The Iron Bridge is one of three bridges on the River Severn that are listed as grade I structures, including Bewdley Bridge and the Severn Bridge, which was opened in 1966. In total, 31 bridges that cross the River Severn are listed, either grade I, II* or II. Four bridges are scheduled monuments, including The Iron Bridge, which are nationally important archaeological bridges. Many reaches of the Severn are prone to severe flooding, prompting the design of some unique bridges to cope with this. There were histori ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low ultimate tensile strength, tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars (rebar) and is usually embedded passively in the concrete before the concrete sets. However, Prestressed_concrete#Post-tensioned_concrete, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist Tension (physics), tensile Stress (mechanics), stresses in particular regions of the concrete that might cause unacceptable frac ...

Spandrel
A spandrel is a roughly triangular space, usually found in pairs, between the top of an arch and a rectangular frame; between the tops of two adjacent arches or one of the four spaces between a circle within a square. They are frequently filled with decorative elements. Meaning There are four or five accepted and cognate meanings of the term ''spandrel'' in architectural and art history, mostly relating to the space between a curved figure and a rectangular boundary – such as the space between the curve of an arch and a rectilinear bounding moulding, or the wallspace bounded by adjacent arches in an arcade and the stringcourse or moulding above them, or the space between the central medallion of a carpet and its rectangular corners, or the space between the circular face of a clock and the corners of the square revealed by its hood. Also included is the space under a flight of stairs, if it is not occupied by another flight of stairs. In a building with more than one floor, ...

BCN Main Line
The BCN Main Line, or Birmingham Canal Navigations Main Line is the evolving route of the Birmingham Canal between Birmingham and Wolverhampton in England. The name ''Main Line'' was used to distinguish the main Birmingham to Wolverhampton route from the many other canals and branches built or acquired by the Birmingham Canal Navigations company. BCN Old Main Line On 24 January 1767 a number of prominent Birmingham businessmen, including Matthew Boulton and others from the Lunar Society, held a public meeting in the White Swan, High Street, Birmingham''Smethwick and the BCN'', Malcolm D. Freeman, 2003, Sandwell MBC and Smethwick Heritage Centre Trust to consider the possibility of building a canal from Birmingham to the Staffordshire and Worcestershire Canal near Wolverhampton, taking in the coalfields of the Black Country. They commissioned the canal engineer James Brindley to propose a route. Brindley came back with a largely level but meandering route via Smethwick, O ...

Cast Iron
Cast iron is a class of iron– carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications a ...

Galton Bridge
The Galton Bridge is a cast-iron bridge in Smethwick, near Birmingham, in central England. Opened in 1829 as a road bridge, the structure has been pedestrianised since the 1970s. It was built by Thomas Telford to carry a road across the new main line of the Birmingham Canal, which was built in a deep cutting. The bridge is above the canal, making it reputedly the highest single-span arch bridge in the world when it was built, wide, and long. The Galton Bridge is in cast iron, forged at the nearby Horseley Ironworks, with masonry abutments. The design includes decorative lamp-posts and X-shaped bracing in the spandrels. In the 1840s, a railway bridge was built from one of the abutments, with a parapet in keeping with the original. The Galton Bridge carried traffic for over 140 years until it was bypassed by a new road, named Telford Way, in the 1970s, and now only carries pedestrians and cyclists. The scheme involved burying the canal in a tunnel, which was named Galton Tunne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
