Light Horse Interchange
The Light Horse Interchange is a motorway interchange located in Eastern Creek, Sydney, Australia at the junction of the M4 and M7 motorways. The interchange is the largest in the southern hemisphere and was opened to traffic in December 2005. The interchange was named in honour of the Australian Light Horse Brigades of World War I, who trained at the Wallgrove Army camp that was located near the site of the interchange prior to deploying overseas. Design and construction In response to a population boom in Sydney's western suburbs, the Government of New South Wales' Sydney Orbital Roads Strategy identified the need for a limited access north-south link. The Westlink M7 project would connect the three existing east-west motorways: the M5 South Western Motorway, the M4 Western Motorway and the M2 Hills Motorway catering for up to 60,000 vehicles per day and providing faster routes to the Sydney central business district. Following a request for tender in 2001, a joint ventur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interchange (road)
In the field of road transport, an interchange (American English) or a grade-separated junction (British English) is a road junction that uses grade separations to allow for the movement of traffic between two or more roadways or highways, using a system of interconnecting roadways to permit traffic on at least one of the routes to pass through the junction without interruption from crossing traffic streams. It differs from a standard intersection, where roads cross at grade. Interchanges are almost always used when at least one road is a controlled-access highway (freeway or motorway) or a limited-access divided highway (expressway), though they are sometimes used at junctions between surface streets. Terminology ''Note:'' The descriptions of interchanges apply to countries where vehicles drive on the right side of the road. For left-side driving, the layout of junctions is mirrored. Both North American (NA) and British (UK) terminology is included. ; Freeway juncti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sydney
Sydney ( ) is the capital city of the state of New South Wales, and the most populous city in both Australia and Oceania.

Stack Interchange
A directional interchange, colloquially known as a stack interchange, is a type of grade-separated junction between two controlled-access highways that allows for free-flowing movement to and from all directions of traffic. These interchanges eliminate the problems of weaving, have the highest vehicle capacity, and vehicles travel shorter distances when compared to different types of interchanges. The first directional interchange built in the world was the Four Level Interchange which opened to Los Angeles traffic in 1949. Definition A directional interchange is a grade separated junction between two roads where all turns that require crossing over or under the opposite road's lanes of travel in order to complete the turn utilize ramps that make a direct or semi-direct connection. The difference between direct and semi-direct connections is how much the motorist deviates from the intended direction of travel while on the ramp; direct ramps are shorter and can handle higher t ...

Flanders Poppy
''Papaver rhoeas'', with common names including common poppy, corn poppy, corn rose, field poppy, Flanders poppy, and red poppy, is an annual herbaceous species of flowering plant in the poppy family Papaveraceae. It is a temperate native with a very wide distribution area, from Africa to temperate and tropical Asia and Europe. It is regarded as an agricultural weed (hence the common names including "corn" and "field"). As the plant thrives in areas of disturbed soil, it was often abundant in agricultural fields before the advent of herbicides. Flushes of poppies may still appear in fields where herbicides are not used, as well as those in fallow. The corn poppy and its cultivars such as the Shirley poppy are widely grown in gardens, and are frequently found in packets of seed labelled "wildflower mixes". Since World War I, it has been used in the Commonwealth as a symbol of remembrance for fallen soldiers. Description ''Papaver rhoeas'' is a variable, erect annual, formi ...

Median Strip
The median strip, central reservation, roadway median, or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways, dual carriageways, freeways, and motorways. The term also applies to divided roadways other than highways, including some major streets in urban or suburban areas. The reserved area may simply be paved, but commonly it is adapted to other functions; for example, it may accommodate decorative landscaping, trees, a median barrier, or railway, rapid transit, light rail, or streetcar lines. Regional terminology There is no international English standard for the term. Median, median strip, and median divider island are common in North American and Antipodean English. Variants in North American English include regional terms such as neutral ground in New Orleans usage. In British English the central reservation or central median the preferred usage; it also occurs widely in formal documents in som ...

Returned & Services League Of Australia
The Returned and Services League of Australia (RSL) is a support organisation for people who have served or are serving in the Australian Defence Force. Mission The RSL's mission is to ensure that programs are in place for the well-being, care, compensation and commemoration of serving and ex-service Defence Force members and their dependants; and promote Government and community awareness of the need for a secure, stable and progressive Australia. However, even as late as the 1970s it was described as an "inherently conservative" organisation. History The League evolved out of concern for the welfare of returned servicemen from the First World War. In 1916, a conference at which representatives from Queensland, South Australia, Tasmania and Victoria were present recommended the formation of The Returned Sailors and Soldiers Imperial League of Australia (RSSILA). New South Wales was admitted to the League the following year and Western Australia in 1918. In 1927, the Austral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pre-cast Concrete
Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and maneuvered into place; examples include precast beams, and wall panels for tilt up construction. In contrast, cast-in-place concrete is poured into site-specific forms and cured on site. Recently lightweight expanded polystyrene foam is being used as the cores of precast wall panels, saving weight and increasing thermal insulation. Precast stone is distinguished from precast concrete by the finer aggregate used in the mixture, so the result approaches the natural product. Overview Precast concrete is employed in both interior and exterior applications, from highway, bridge, and hi-rise projects to tilt-up building construction. By producing precast concrete in a controlled environment (typically referred to as a precast plant), the precast concrete is afforded the opportunity to properl ...

Sydney Central Business District
The Sydney central business district (CBD) is the historical and main Central business district, commercial centre of Sydney. The CBD is Sydney's city centre, or Sydney City, and the two terms are used interchangeably. Colloquially, the CBD or city centre is often referred to simply as "Town" or "the City". The Sydney city centre extends southwards for about from Sydney Cove, the point of first European settlement in which the Regions of Sydney, Sydney region was initially established. Due to its pivotal role in Australia's early history, it is one of the oldest established areas in the country. Geographically, its north–south axis runs from Circular Quay in the north to Central railway station, Sydney, Central railway station in the south. Its east–west axis runs from a chain of parkland that includes Hyde Park, Sydney, Hyde Park, The Domain, Sydney, The Domain, Royal Botanic Gardens, Sydney, Royal Botanic Gardens and Farm Cove, New South Wales, Farm Cove on Port Jackson, S ...

Quarantine
A quarantine is a restriction on the movement of people, animals and goods which is intended to prevent the spread of disease or pests. It is often used in connection to disease and illness, preventing the movement of those who may have been exposed to a communicable disease, yet do not have a confirmed medical diagnosis. It is distinct from medical isolation, in which those confirmed to be infected with a communicable disease are isolated from the healthy population. Quarantine considerations are often one aspect of border control. The concept of quarantine has been known since biblical times, and is known to have been practised through history in various places. Notable quarantines in modern history include the village of Eyam in 1665 during the bubonic plague outbreak in England; East Samoa during the 1918 flu pandemic; the Diphtheria outbreak during the 1925 serum run to Nome, the 1972 Yugoslav smallpox outbreak, the SARS pandemic, the Ebola pandemic and extensive ...

Cantilever
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In the southe ...
