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] |
Cape Breton And Central Nova Scotia Railway
The Cape Breton and Central Nova Scotia Railway is a short line railway that operated in the Canadian province of Nova Scotia. CBNS operated () of main line and associated spurs between Truro in the central part of the province to Point Tupper on Cape Breton Island. The rail lines operated by CBNS were previously owned by the Canadian National Railway. CBNS began operations in 1994 after the rail lines was purchased in October 1993 by the holding company RailTex. The purchase and operation of this route made CBNS one of the first short line railways to operate a route previously owned by a Canadian Class I railroad. On February 4, 2000, RailTex and all of its assets, including CBNS, were sold to the holding company RailAmerica. On December 12, 2012, RailAmerica and all of its assets, including CBNS, were sold to the holding company Genesee & Wyoming. Route The CBNS main line crosses varied scenery in central and eastern Nova Scotia including mixed farmland, river val ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bascule Bridge
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Governor General Of Canada
The governor general of Canada (french: gouverneure générale du Canada) is the federal viceregal representative of the . The is head of state of Canada and the 14 other Commonwealth realms, but resides in oldest and most populous realm, the United Kingdom. The , on the advice of Canadian prime minister, appoints a governor general to carry on the Government of Canada in the 's name, performing most of constitutional and ceremonial duties. The commission is for an indefinite period—known as serving ''at Majesty's pleasure''—though five years is the usual length of time. Since 1959, it has also been traditional to alternate between francophone and anglophone officeholders—although many recent governors general have been bilingual. The office began in the 17th century, when the French crown appointed governors of the colony of Canada. Following the British conquest of the colony, the British monarch appointed governors of the Province of Quebec (later the Canadas) ...

Cofferdam
A cofferdam is an enclosure built within a body of water to allow the enclosed area to be pumped out. This pumping creates a dry working environment so that the work can be carried out safely. Cofferdams are commonly used for construction or repair of permanent dams, oil platforms, bridge piers, etc., built within water. These cofferdams are usually welded steel structures, with components consisting of Larssen sheet piling, sheet piles, Wale (ship part), wales, and cross timber framing, braces. Such structures are usually dismantled after the construction work is completed. The origin of the word comes from ''coffer'' (originally from Latin ''cophinus'' meaning "basket") and ''dam'' from Proto-Germanic, Proto-German ''*dammaz'' meaning "barrier across a stream of water to obstruct its flow and raise its level"). Uses For dam construction, two cofferdams are usually built, one upstream and one downstream of the proposed dam, after an alternative diversion tunnel or channel ...

Bedrock
In geology, bedrock is solid Rock (geology), rock that lies under loose material (regolith) within the crust (geology), crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysics, geophysical methods is an important task in most civil engineering projects. Superficial deposition (geology), deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave ...

Overburden
In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore. Overburden is removed during surface mining, but is typically not contaminated with toxic components. Overburden may also be used to restore an exhausted mining site during reclamation. Interburden is material that lies between two areas of economic interest, such as the material separating coal seams within strata.Peng, Syd S. (1986) ''Coal Mine Ground Control'' (2nd edition), Wiley, New York, page 303, Analogous uses Overburden is also used for all soil and ancillary material above the bedrock horizon in a given area. By analogy, overburden is also used to describe the soil and other material that lies ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravity, gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the #Phase and amplitude, phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see ''#Timing, Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal cycle, diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Gillespie Reid
Sir Robert Gillespie Reid (12 October 1842 – 3 June 1908) was a Scottish railway contractor most famous for building large railway bridges in Canada and the United States. Founder of Reid Newfoundland Company, from 1889 until his death, he built, owned, and operated the Newfoundland Railway. Early career As a young man, Reid spent a few years in Australia mining gold. In 1871, Reid settled in North America, where he began his career as a contractor. He built one section of the Canadian Pacific Railway, and was responsible for the erection of the international bridge over the Niagara River, the international railway bridge over the Rio Grande and the Lachine bridge over the St. Lawrence.

In 1893, he signed a contract with the government of Newfoundland, and as president of the Reid Newfoundland Company he built the railway from Whitbourne to Port aux Basques. The contract specified he work the line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Hawkesbury, Nova Scotia
Port Hawkesbury (Scottish Gaelic: ''Baile a' Chlamhain'') is a municipality in southern Cape Breton Island, Nova Scotia, Canada. While within the historical county of Inverness, it is not part of the Municipality of Inverness County. History The end of glaciation began 13,500 years ago /sup> and ended with the region becoming largely ice free 11,000 years ago. The earliest evidence of Palaeo-Indian settlement in the region follows rapidly after deglaciation. /sup> Several thousand years ago, the territory of the province became known a part of the territory of the Mi'kmaq nation of Mi'kma'ki. Mi'kma'ki includes what is now the Maritimes, parts of Maine, Newfoundland and the Gaspé Peninsula. The town of Port Hawkesbury is in the traditional Mi'kmaw district of Unama'ki. In 1605, French colonists established the first permanent European settlement in the future Canada (and the first north of Florida) at Port Royal, founding what would become known as Acadia. /sup> Wh ...

Point Tupper, Nova Scotia
Point Tupper is a rural community in Richmond County, Nova Scotia, on the Strait of Canso, in western Cape Breton Island. History Extensive land grants in the area were acquired in 1863 by Henry Nicholas Paint, of Belle Vue, Canso, member of Parliament for Richmond (Nova Scotia electoral district), who started to promote a township on the site, a project which he continued doggedly until his death in 1921. According to Paint, the site was named by Sir James Kempt after Ferdinand Brock Tupper, the Guernsey historian. Transportation boom and decline In the 1880s, Point Tupper became the eastern terminal for a railcar ferry service operated from the port of Mulgrave, directly opposite on the western shore of the Strait of Canso. The Intercolonial Railway line continued east from Point Tupper to Sydney, making Point Tupper an extremely important port for the economy of Cape Breton Island. In 1955, the Canso Causeway opened, closing the railcar ferry service and resulting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intercolonial Railway
The Intercolonial Railway of Canada , also referred to as the Intercolonial Railway (ICR), was a historic Canadian railway that operated from 1872 to 1918, when it became part of Canadian National Railways. As the railway was also completely owned and controlled by the Government of Canada, the Intercolonial was also one of Canada's first Crown corporations. Origins The idea of a railway connecting Britain's North American colonies arose as soon as the railway age began in the 1830s. In the decades following the War of 1812 and ever-mindful of the issue of security, the colonies of Upper and Lower Canada (later the Province of Canada after 1840) wished to improve land-based transportation with the Atlantic coast colonies of Nova Scotia and New Brunswick, and to a lesser extent Prince Edward Island and Newfoundland. A railway connection from the Province of Canada to the British colonies on the coast would serve a vital military purpose during the winter months when the waters o ...
