Commonwealth Avenue Bridge
The Commonwealth Avenue Bridge are two parallel pre-stressed concrete box girder road bridges that carry Commonwealth Avenue across Lake Burley Griffin, and connect and in Canberra, in the Australian Capital Territory, Australia. History The current bridge is the fourth crossing over the Molonglo River. The first Commonwealth Avenue Bridge, completed 1916, was damaged in the 1922 flood. The second, using three Leychester-type trusses, was completed in 1924 and damaged in floods a year later. The third bridge, completed in 1927, was a modification of the 1924 bridge, by raising the bridge by and adding a fourth truss. At that time, Molonglo River was not dammed to form Lake Burley Griffin. Building on the plan developed by Walter Burley Griffin, in 1957 William Holford proposed to the Australian Government that the Molonglo be dammed near Yarralumla and that Canberra's 'two halves' should be joined via a lake. Construction of the Commonwealth Avenue Bridge began in March ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Burley Griffin
Lake Burley Griffin is an artificial lake in the centre of Canberra, the capital of Australia. It was completed in 1963 after the Molonglo River, which ran between the city centre and Parliamentary Triangle, was dammed. It is named after Walter Burley Griffin, the American architect who won the competition to design the city of Canberra. Griffin designed the lake with many geometric motifs, so that the axes of his design lined up with natural geographical landmarks in the area. However, government authorities changed his original plans, and no substantial work was completed before he left Australia in 1920. Griffin's proposal was further delayed by the Great Depression and World War II, and it was not until the 1950s that planning resumed. After political disputes and consideration of other proposed variations, excavation work began in 1960 with the energetic backing of Australian Prime Minister Robert Menzies. After the completion of the bridges and dams, the dams were locked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walter Burley Griffin
Walter Burley Griffin (November 24, 1876February 11, 1937) was an American architect and landscape architect. He is known for designing Canberra, Australia's capital city and the New South Wales towns of Griffith, New South Wales, Griffith and Leeton, New South Wales, Leeton. He has been credited with the development of the L-shaped floor plan, the carport and an innovative use of reinforced concrete. Influenced by the Chicago-based Prairie School, Griffin developed a unique modern architecture, modern style. He worked in partnership with his wife Marion Mahony Griffin. In 28 years they designed over 350 buildings, landscape and urban-design projects as well as designing construction materials, interiors, furniture and other household items. Early life Griffin was born in 1876 in Maywood, Illinois, a suburb of Chicago. He was the eldest of the four children of George Walter Griffin, an insurance agent, and Estelle Burley Griffin. His family moved to Oak Park, Illinois, Oak Pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bridges Completed In 1963
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] |
Road Bridges In The Australian Capital Territory
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 ...

Cloverleaf Interchange
A cloverleaf interchange is a two-level interchange in which all turns are handled by slip roads. To go left (in right-hand traffic; reverse directions in left-driving regions), vehicles first continue as one road passes over or under the other, then exit right onto a one-way three-fourths loop ramp (270°) and merge onto the intersecting road. The objective of a cloverleaf is to allow two highways to cross without the need for any traffic to be stopped by traffic lights. The limiting factor in the capacity of a cloverleaf interchange is traffic weaving. Overview Cloverleaf interchanges, viewed from overhead or on maps, resemble the leaves of a four-leaf clover or less often a 3-leaf clover. In the United States, cloverleaf interchanges existed long before the Interstate system. They were originally created for busier interchanges that the original diamond interchange system could not handle. Their chief advantage was that they were free-flowing and did not require t ...

Span (engineering)
Span is the distance between two intermediate supports for a structure, e.g. a beam or a bridge. A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of antennas or for aerial tramways. The span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and deflection. The maximum bending moment M_ and deflection \delta_in the pictured beam is found using: :M_ = \frac :\delta_ = \frac = \frac where :q = Uniformly distributed load :L = Length of the beam between two supports (span) :E = Modulus of elasticity :I = Area moment of inertia Note that the maximum bending moment and deflection occur midway between the two supports. From this it follows that if the span is doubled, the maximum moment (and with it the stress) will quadruple, and deflection will increase by a factor of sixteen. For long-distance rope spa ...

Yarralumla, Australian Capital Territory
Yarralumla () is a large inner south suburb of Canberra, the capital city of Australia. Located approximately south-west of the city, Yarralumla extends along the south-west bank of Lake Burley Griffin from Scrivener Dam to Commonwealth Avenue. In 1828, Henry Donnison, a Sydney merchant, was granted a lease on the western side of Stirling Ridge. Donnison's land was named ''Yarralumla'' in a survey of the area conducted in 1834, apparently after the indigenous people's term for the area. It was also spelt ''Yarrolumla'' in other documents. In 1881, the estate was bought by Frederick Campbell, grandson of Robert Campbell who had built a house at nearby Duntroon. Frederick completed the construction of a large, gabled, brick house on his property in 1891 that now serves as the site of Government House, the official residence of the Governor-General of Australia. Campbell's house replaced an elegant, Georgian-style homestead, the main portions of which were erected from local s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
