Birkenhead Bridge
The Birkenhead Bridge is a bascule bridge in Adelaide, Australia that crosses the Port River. In February 1938, the Government of South Australia awarded a contract to Adelaide Construction to build a bridge across the Port River from Birkenhead to Port Adelaide, with Perry Engineering contracted to supply the steelwork. The bridge was opened on 14 December 1940 by Governor Malcolm Barclay-Harvey. It was one of only four bascule bridges in the world adapted for use by trolleybuses. In 2014, two of the four road lanes were converted into pedestrian and bike paths. In 2020, the timber road deck has been replaced with fibre reinforced polymer and the timber footpath with aluminium. The bridge is listed on the South Australian Heritage Register The South Australian Heritage Register, also known as the SA Heritage Register, is a statutory register of historic places in South Australia. It extends legal protection regarding demolition and development under the ''Heritage Places Ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port River
The Port River (officially known as the Port Adelaide River) is part of a tidal estuary located north of the Adelaide city centre in the Australian state of South Australia. It has been used as a shipping channel since the beginning of European settlement of South Australia in 1836, when Colonel Light selected the site to use as a port. Before colonisation, the Port River region and the estuary area were known as Yerta Bulti (or Yertabulti) by the Kaurna people, and used extensively as a source of food and plant materials to fashion artefacts used in daily life. The Port River dolphins are a popular tourist attraction. Geography The Port River is the western branch of the largest tidal estuary on the eastern side of Gulf St Vincent. The whole estuarine area, sometimes called the Port River estuary, includes Barker Inlet, Torrens Island, Garden Island, and to a greater or lesser extent touches the suburbs of St Kilda, Bolivar, Dry Creek, Port Adelaide, New Port, and (up ...

Governor Of South Australia
The governor of South Australia is the representative in South Australia of the Monarch of Australia, currently King Charles III. The governor performs the same constitutional and ceremonial functions at the state level as does the governor-general of Australia at the national level. In accordance with the conventions of the Westminster system of parliamentary government, the governor nearly always acts solely on the advice of the head of the elected government, the Premier of South Australia. Nevertheless, the governor retains the reserve powers of the Crown, and has the right to dismiss the Premier. As from June 2014, the Queen, upon the recommendation of the Premier, accorded all current, future and living former governors the title 'The Honourable' for life. The first six governors oversaw the colony from proclamation in 1836, until self-government and an elected Parliament of South Australia was granted in the year prior to the inaugural 1857 election. The first Australian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Adelaide
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges Completed In 1940
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.

Bascule Bridges
A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed. The name comes from the French term for balance scale, which employs the same principle. Bascule bridges are the most common type of movable span because they open quickly and require relatively little energy to operate, while providing the possibility for unlimited vertical clearance for marine traffic. History Bascule bridges have been in use since ancient times, but until the adoption of steam power in the 1850s, very long, heavy spans could not be moved quickly enough for practical application. Types There are three types of bascule bridge and the counterweights to the span may be located above or below the bridge deck. The fixed-trunnion (sometimes a "Chicago" bascule) rotates around a large axle that raises the sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fibre-reinforced Plastic
Fibre-reinforced plastic (FRP; also called fibre-reinforced polymer, or in American English ''fiber'') is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass (in fibreglass), carbon (in carbon-fibre-reinforced polymer), aramid, or basalt. Rarely, other fibres such as paper, wood, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries. They are commonly found in ballistic armour and cylinders for self-contained breathing apparatuses. Process definition A polymer is generally manufactured by step-growth polymerization or addition polymerization. When combined with various agents to enhance or in any way alter the material properties of polymers, the result is referred to as a plastic. Composite plastics refers to those types of plastic ...

ABC Radio Adelaide
ABC Radio Adelaide (call sign: 5AN) is the ABC Local Radio station for Adelaide. It is broadcast at 891 kHz on the AM band. It is also available on Digital TV in Adelaide. History 5AN started transmitting on 15 October 1937 with equipment located in the central telephone exchange, and a radio mast located in Post Office Place. The station transmitter moved to Brooklyn Park, already the site of 5CL's transmitter, on 4 May 1944. The radio mast was moved from the east side of the building to the south side in 1952 to make way for a road to the projected new airport. The proximity of the transmitter site to the airport was inconvenient for both operations, so a new transmitter site was built in open fields at Pimpala, at the corner of Sherriffs and Hillier Roads, Reynella, and was opened on 20 September 1961 by the Postmaster-General C W Davidson. New transmitters for 5AN and 5CL, rated at 50 kW, manufactured by STC, had been installed in the building by the Postma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Among Ourselves
The Municipal Tramways Trust (MTT) was established by the Government of South Australia in December 1906 to purchase all of the horse-drawn tramways in Adelaide, Australia. The Trust subsequently also ran petrol and diesel buses and electric trolleybuses. It ceased to exist on 8 December 1975, when its functions were transferred to the State Transport Authority, which also operated Adelaide's suburban train services. History The MTT was created in December 1906 as a tax exempt body with eight board members, mostly appointed by local councils and a small number of state government appointees. Board members were appointed for terms of six years with a provision that half the members should retire every three years.Inaugural MTT board members in 1907 were: * AB Moncrieff, Government appointee, chairman and engineer-in-chief; succeeded in 1922 by Edward Bakewell *Thomas Gill, Government appointee *J.R.

Trolleybus
A trolleybus (also known as trolley bus, trolley coach, trackless trolley, trackless tramin the 1910s and 1920sJoyce, J.; King, J. S.; and Newman, A. G. (1986). ''British Trolleybus Systems'', pp. 9, 12. London: Ian Allan Publishing. .or trolleyDunbar, Charles S. (1967). ''Buses, Trolleys & Trams''. Paul Hamlyn Ltd. (UK). Republished 2004 with or 9780753709702.) is an electric bus that draws power from dual overhead wires (generally suspended from roadside posts) using spring-loaded trolley poles. Two wires, and two trolley poles, are required to complete the electrical circuit. This differs from a tram or streetcar, which normally uses the track as the return path, needing only one wire and one pole (or pantograph). They are also distinct from other kinds of electric buses, which usually rely on batteries. Power is most commonly supplied as 600-volt direct current, but there are exceptions. Currently, around 300 trolleybus systems are in operation, in cities and towns in 4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
