Megarritys Bridge
Megarritys Bridge is a heritage-listed bridge across the Megarritys Creek, located at Warragamba Dam in the outer south-western Sydney suburb of Warragamba in the Wollondilly Shire local government area of New South Wales, Australia. It was built by Metropolitan Water, Sewerage and Drainage Board. The bridge is also known as Megarritys Bridge. The property is owned by Water NSW, an agency of the Government of New South Wales. It was added to the New South Wales State Heritage Register on 18 November 1999. History Megarritys Creek Bridge is a concrete arch bridge spanning Megarritys Creek. The construction of the bridge provided a vital link across the Creek for the operation of the Warragamba Emergency Scheme. While it was designed eventually to carry the No 1 outlet main from Warragamba Dam, for the Emergency Scheme it carried the main from the weir to Prospect Reservoir. Description The construction incorporated an arch formwork design using tubular steel scaffold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warragamba, New South Wales
Warragamba is a town in New South Wales, Australia, in Wollondilly Shire. Located on the eastern edge of the Blue Mountains, Warragamba is one and a half hour's drive west of Sydney. The name Warragamba comes from the aboriginal words ''Warra'' and ''Gamba'' meaning 'water running over rocks'. History In 1804, George William Evans became the first white man to discover the Warragamba River, penetrating upstream to the present site of Warragamba Dam. However, for Indigenous peoples, the river and the valley were an integral part of daily life, and remain today a significant place of cultural heritage. Originally constructed as a workers' settlement during the construction of Warragamba Dam, Sydney's primary water source, in the 1940s the modern town of Warragamba remains on the same site adjacent the dam. The town was built from scratch, including homes, shops, schools and other facilities. On completion of the dam being built many workers bought their homes from the Wat ...

Arch Bridge
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today. History Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks, the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction. A list of Roman bridges compiled by the engineer Colin O'Connor featur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arch Bridges In Australia
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...

Bridges In New South Wales
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] |

Historic Bridges Of New South Wales
This list documents historical bridges located in New South Wales, Australia. Road, rail and pedestrian bridges are listed. Generally bridges built before WWII (1939) have been included in this list. Historical context Bridge construction in New South Wales starts with the needs of the first settlers and continues through to the present day with advanced bridge design. The infant colony had limited expertise and limited materials. As time passed, techniques and materials were developed that allowed greater spans to be crossed and therefore expansion of the colony into otherwise inaccessible areas. The Office of Public Works and Services, New South Wales, NSW Public Works Department was under pressure from a cash strapped government to produce as much road and bridge work for as little cost as possible. The cheapest bridge was the Truss bridge, timber truss which could be built with local timber. All bridges are unique in the sense that the bridges were built using various techno ...

Government Agency
A government or state agency, sometimes an appointed commission, is a permanent or semi-permanent organization in the machinery of government that is responsible for the oversight and administration of specific functions, such as an administration. There is a notable variety of agency types. Although usage differs, a government agency is normally distinct both from a department or ministry, and other types of public body established by government. The functions of an agency are normally executive in character since different types of organizations (''such as commissions'') are most often constituted in an advisory role—this distinction is often blurred in practice however, it is not allowed. A government agency may be established by either a national government or a state government within a federal system. Agencies can be established by legislation or by executive powers. The autonomy, independence, and accountability of government agencies also vary widely. History Early exa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
