Tourle Street Bridge
The Tourle Street Bridge is a pair of road bridges that carry Tourle Street across the Hunter River from Mayfield West to Kooragang in the Hunter Region of New South Wales, Australia. The original steel truss bridge opened on 20 February 1965. On 6 May 2009 a two-lane replacement concrete bridge Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time.

In June 2018, a nearly identical parallel bridge opened on the site of the 1965 bridge with the 2009 built bridge becoming one way heading north.

Hunter River (New South Wales)
The Hunter River (Wonnarua: ''Coquun'') is a major river in New South Wales, Australia. The Hunter River rises in the Liverpool Range and flows generally south and then east, reaching the Tasman Sea at Newcastle, the second largest city in New South Wales and a major harbour port. Its lower reaches form an open and trained mature wave dominated barrier estuary. Course and features The Hunter River rises on the western slopes of Mount Royal Range, part of the Liverpool Range, within Barrington Tops National Park, east of Murrurundi, and flows generally northwest and then southwest before being impounded by Lake Glenbawn; then flowing southwest and then east southeast before reaching its mouth of the Tasman Sea, in Newcastle between Nobbys Head and Stockton. The river is joined by ten tributaries upstream of Lake Glenbawn; and a further thirty-one tributaries downstream of the reservoir. The main tributaries are the Pages, Goulburn, Williams and the Paterson rivers and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete Bridge
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bridges Completed In 2009
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] |
Roads & Maritime Services
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which i ...

Main Roads (periodical)
The Department of Main Roads (DMR) was an agency of the New South Wales Government, responsible for planning, constructing and maintaining major road infrastructure. The DMR directly managed highways and major roads and provided funding to local councils for regional and local roads. The agency was merged with other agencies to form the Roads & Traffic Authority in 1989. History The Ministry of Transport was established in December 1932 by way of the ''Transport (Division of Functions) Act of 1932'', following the dismissal of the Lang Government and the subsequent state election. The ministry consisted of three departments, including the Department of Main Roads and the Department of Road Transport & Tramways. The departments were established as the incoming Stevens Government and its Minister for Transport Michael Bruxner sought to reorganise the management of the road network in NSW. The new department essentially resumed the functions that had been held by the NSW Main Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kooragang
Kooragang () is the northernmost and largest suburb of the city of Newcastle, in the Hunter Region of New South Wales, Australia. Dominated by Kooragang Island, the eastern part of the suburb is primarily industrial, while the western part of the suburb consists of nature reserves. Covering an area of , at the , there were no people living in the suburb. Geography Kooragang extends from in the southeast, to the eastern bridge at Although known as the "Hexham bridge", there are actually two bridges crossing the Hunter River.

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
