Mooney Mooney Bridge
The Mooney Mooney Bridge, officially the Mooney Mooney Creek Bridge, and popularly known as The NSW Big Dipper Bridge, is a twin cantilever bridge that carries the Pacific Motorway (M1) across Mooney Mooney Creek, located near in the Brisbane Water National Park on the Central Coast of New South Wales, Australia. The concrete box girder bridge was opened on 14 December 1986 by the Prime Minister of Australia, Bob Hawke, and is owned and maintained by Transport for NSW, an agency of the Government of New South Wales. The Pacific Motorway is the main road link between Sydney, the Central Coast and the Hunter Region. The only other road that links all three regions is the Pacific Highway (B83) which from to follows a scenic winding route. History The Pacific Highway (now known as B83) served as the only highway route between Sydney and the Central Coast and the Hunter Region. The original 1930 two-lane steel truss bridge carried the Old Pacific Highway across Mooney Mooney ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Government Agency
A government agency or state agency, sometimes an appointed commission, is a permanent or semi-permanent organization in the machinery of government (bureaucracy) that is responsible for the oversight and administration of specific functions, such as an Administration (government), administration. There is a notable variety of agency types. Although usage differs, a government agency is normally distinct both from a department or Ministry (government department), 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.

Girder
A girder () is a Beam (structure), beam used in construction. It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing ''flanges'' separated by a stabilizing ''web'', but may also have a box girder, box shape, Z shape, or other forms. Girders are commonly used to build bridges. A girt is a vertically aligned girder placed to resist shear loads. Small steel girders are Rolling (metalworking), rolled into shape. Larger girders (1 m/3 feet deep or more) are made as plate girders, welded or bolted together from separate pieces of steel plate. The Warren truss, Warren type girder replaces the solid web with an open latticework truss between the flanges. This arrangement combines strength with economy of materials, minimizing weight and thereby reducing loads and expense. Patented in 1848 by its designers James Warren (engineer), James Warren and Willoughby Theobald Monzani, its st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parapet
A parapet is a barrier that is an upward extension of a wall at the edge of a roof, terrace, balcony, walkway or other structure. The word comes ultimately from the Italian ''parapetto'' (''parare'' 'to cover/defend' and ''petto'' 'chest/breast'). Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires. Parapet types Parapets may be plain, embattled, perforated or panelled, which are not mutually exclusive terms. *Plain parapets are upward extensions of the wall, sometimes with a coping at the top and corbel below. *Embattled parapets may be panelled, but are pierced, if not ...

Aesthetics
Aesthetics (also spelled esthetics) is the branch of philosophy concerned with the nature of beauty and taste (sociology), taste, which in a broad sense incorporates the philosophy of art.Slater, B. H.Aesthetics ''Internet Encyclopedia of Philosophy,'' , accessed on 15 September 2024. Aesthetics examines values about, and Critical thinking, critical judgments of, artistic taste and preference. It thus studies how Artist, artists imagine, create, and perform works of art, as well as how people use, enjoy, and criticize art. Aesthetics considers why people consider certain things beautiful and not others, as well as how objects of beauty and art can affect our moods and our beliefs. Aesthetics tries to find answers to what exactly is art and what makes good art. It considers what happens in our minds when we view Visual arts, visual art, listen to music, read poetry, enjoy delicious food, and engage in large artistic projects like creating and experiencing plays, fashion shows ...

Toll Road
A toll road, also known as a turnpike or tollway, is a public or private road for which a fee (or ''Toll (fee), toll'') is assessed for passage. It is a form of road pricing typically implemented to help recoup the costs of road construction and Road maintenance, maintenance. Toll roads have existed in some form since Classical antiquity, antiquity, with tolls levied on passing travelers on foot, wagon, or horseback; a practice that continued with the automobile, and many modern tollways charge fees for motor vehicles exclusively. The amount of the toll usually varies by vehicle type, weight, or number of axles, with freight trucks often charged higher rates than cars. Tolls are often collected at toll plazas, toll booths, toll houses, toll stations, toll bars, toll barriers, or toll gates. Some toll collection points are automatic, and the user deposits money in a machine which opens the gate once the correct toll has been paid. To cut costs and minimise time delay, many tolls ...

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. There are several types of truss bridges, including some with simple designs that were among the first bridges designed in the 19th and early 20th centuries. A truss bridge is economical to construct primarily 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 the strength to mainta ...

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highway
A highway is any public or private road or other public way on land. It includes not just major roads, but also other public roads and rights of way. In the United States, it is also used as an equivalent term to controlled-access highway, or a translation for ''motorway'', ''Autobahn'', ''autostrada'', ''autoroutes of France, autoroute'', etc. According to Merriam-Webster, the use of the term predates the 12th century. According to Online Etymology Dictionary, Etymonline, "high" is in the sense of "main". In North American English, North American and Australian English, major roads such as controlled-access highways or arterial (road), arterial roads are often state highways (Canada: provincial highways). Other roads may be designated "county highways" in the US and Ontario. These classifications refer to the level of government (state, provincial, county) that maintains the roadway. In British English, "highway" is primarily a legal term. Everyday use normally implies roads, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
