Barra Strait Bridge
The Barra Strait Bridge is a Canadian road bridge crossing the Barra Strait of Bras d'Or Lake, carrying Nova Scotia Route 223 between Iona, Victoria County, on the West side, and Grand Narrows, Cape Breton County (Cape Breton Regional Municipality) on the east side. The bridge incorporates a double leaf bascule section at its eastern end to permit the continued passage of marine traffic through the strait. History Ferry service A ferry service operated across the Barra Strait, between Grand Narrows and Iona, starting in 1847, and continued for the next 146 years. In the late 1880s the Intercolonial Railway of Canada bridged the strait with the Grand Narrows Bridge (also known as the Barra Strait Railway Bridge), which is still the longest railway bridge in the province, crossing between Uniacke Point to the west and Kelly Point to the east. The Nova Scotia Department of Highways took over the Barra Strait motor vehicles ferry service in 1927 and continued the service be ...

Grand Narrows Bridge
The Grand Narrows Bridge is a Canadian railway bridge crossing between Victoria County, Nova Scotia, and Cape Breton County. At , it is the longest railroad bridge in the province. The bridge incorporates a swing span at its eastern end to permit the continued passage of marine traffic through the strait. It is an arch truss design, consisting of seven riveted steel trusses, each long, set on cut stone piers. The Grand Narrows Bridge crosses the Barra Strait of Bras d'Or Lake, carrying the Sydney Subdivision of the Cape Breton and Central Nova Scotia Railway (CBNS) between Iona, Victoria County, on the West side, and Grand Narrows, Cape Breton County (Cape Breton Regional Municipality) on the east side. In 1993, a double leaf bascule bridge, the Barra Strait Bridge, carrying Route 223, was constructed just to the northeast of the Grand Narrows Bridge. The Government of Nova Scotia had operated a small ferry service for motor vehicles across the strait, starting in 1847 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferry
A ferry is a ship, watercraft or amphibious vehicle used to carry passengers, and sometimes vehicles and cargo, across a body of water. A passenger ferry with many stops, such as in Venice, Italy, is sometimes called a water bus or water taxi. Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels. Ship connections of much larger distances (such as over long distances in water bodies like the Mediterranean Sea) may also be called ferry services, and many carry vehicles. History In ancient times The profession of the ferryman is embodied in Greek mythology in Charon, the boatman who transported souls across the River Styx to the Underworld. Speculation that a pair of oxen propelled a ship having a water wheel can be found in 4th century Roman literature "''Anonymus De Rebus Bellicis''". Though impractical, there is no reason why it could not work ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prestressed Concrete
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" ( compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. Post-tensioned concreted is "structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads." This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire strands or threaded bars that are most commonly made from high-tensile steels, carbon fiber or aramid fiber. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concrete when subject to any subsequent compression forces and of ductile high-strength steel when sub ...

Abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end which provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus of a column in classical architecture may also serve as an abutment to an arch. The word derives from the verb "abut", meaning to "touch by means of a mutual border". Use in engineering An abutment may be us ...

Pier (architecture)
A pier, in architecture, is an upright support for a structure or superstructure such as an arch or bridge. Sections of structural walls between openings (bays) can function as piers. External or free-standing walls may have piers at the ends or on corners. Description The simplest cross section of the pier is square, or rectangular, but other shapes are also common. In medieval architecture, massive circular supports called drum piers, cruciform (cross-shaped) piers, and compound piers are common architectural elements. Columns are a similar upright support, but stand on a round base. In buildings with a sequence of bays between piers, each opening (window or door) between two piers is considered a single bay. Bridge piers Single-span bridges have abutments at each end that support the weight of the bridge and serve as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support the ends of spans betwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars ( rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Girder Bridge
A girder bridge is a bridge that uses girders as the means of supporting its deck. The two most common types of modern steel girder bridges are plate and box. The term "girder" is often used interchangeably with "beam" in reference to bridge design. However, some authors define beam bridges slightly differently from girder bridges. A girder may be made of concrete or steel. Many shorter bridges, especially in rural areas where they may be exposed to water overtopping and corrosion, utilize concrete box girder. The term "girder" is typically used to refer to a steel beam. In a beam or girder bridge, the beams themselves are the primary support for the deck, and are responsible for transferring the load down to the foundation. Material type, shape, and weight all affect how much weight a beam can hold. Due to the properties of the second moment of area, the height of a girder is the most significant factor to affect its load capacity. Longer spans, more traffic, or wider spacing o ...

Lavalin
Lavalin was a Canadian civil engineering and construction firm based in Montreal, Quebec. After a major expansion program in the 1980s that led to financial difficulties, in 1991 Lavalin merged with its long-time competitor, Surveyer, Nenniger & Chenevert Consulting Engineers (SNC), to become today's SNC-Lavalin, forming one of the ten largest engineering firms in the world. History Lavalin was formed in 1936, through the partnership of Jean-Paul Lalonde and Romeo Valois of Montreal. The company was relatively small until Bernard Lamarre joined Lavalin in 1952, after marrying Louise Lalonde, Jean-Paul's daughter.Grant, 331. Now known as ''Lalonde, Valois, Lamarre, Valois et Associés'', the group was reorganised as Lavalin, Inc. Lamarre became head in 1962, and started a major international expansion. By 1970 the company was a major contractor. During the decade, in a partnership with Bechtel of the United States, the company managed the James Bay Project.Funding Universe As Lavali ...
