Tom Uglys Bridge
Tom Uglys Bridge are two road bridges, completed in 1929 and 1987, that carry the Princes Highway across the Georges River in southern Sydney, in the state of New South Wales, Australia. The bridges link the St George area at Blakehurst to the Sutherland Shire at Sylvania. Tom Uglys Bridge is one of six major road crossings of Georges River. The 1929 Pratt truss bridge is listed on the New South Wales State Heritage Register and carries three lanes of northbound vehicular traffic on the Princes Highway. The 1987 concrete box girder bridge was built to the east of the older bridge and carries the three southbound lanes of the highway. Both bridges have shared bicycle and pedestrian pathways. Tom Uglys Point ferries Tenders were called to construct a punt for Tom Ugly's Point in 1864. A hand-operated punt service from Tom Ugly's Point to Horse Rock Point commenced. The ferry service was improved and expanded over the years. In 1882 a steam-driven ferry, guided by steel cabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Concrete
Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic, which means that ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Box Girder
A box girder or tubular girder (or box beam) is a girder that forms an enclosed tube with multiple walls, as opposed to an i-beam, - or H-beam. Originally constructed of wrought iron joined by riveting, they are now made of rolled steel, rolled or welded steel, aluminium extrusions or prestressed concrete. Compared to an i-beam, -beam, the advantage of a box girder is that it better resists Torsion (mechanics), torsion. Having multiple vertical Web (other)#Engineering, webs, it can also carry more load than an of equal height (although it will use more material than a taller -beam of equivalent capacity). The distinction in naming between a box girder and a tubular girder is imprecise. Generally the term ''box'' girder is used, especially if it is rectangular in section. Where the girder carries its "content" ''inside'' the "box", such as the Britannia Bridge, it is termed a ''tubular'' girder. ''Tubular'' girder is also used if the girder is round or oval in cross-sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Road Bridge
A bridge is a structure built to Span (engineering), span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path 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, 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 in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of ...

Cable Ferry
A cable ferry (including the types chain ferry, swing ferry, floating bridge, or punt) is a ferry that is guided (and in many cases propelled) across a river or large body of water by cables connected to both shores. Early cable ferries often used either rope or steel chains, with the latter resulting in the alternative name of chain ferry. Both of these were largely replaced by wire cable by the late 19th century. Types Cable ferries can be typified by their size and construction, their usage (passenger, animal, vehicle) and requirements (length of crossing, amount of other shipping), their cables (wire rope, chain, or both), and their propulsion (water current, engine, manual). The choice of cable depends partially on the requirements of the crossing but also on the historical context. For example, the numerous cable ferries across Australian and Canadian rivers seem to use wire rope exclusively, whereas the older crossings across busy tidal rivers in England all use chain. ...
