Provencher Bridge (Winnipeg)
The Provencher Bridge (french: Pont Provencher) is a set of paired bridges—a four-lane vehicular bridge and a suspended pedestrian bridge (called Esplanade Riel)—across the Red River in Winnipeg, Manitoba. The bridge links downtown Winnipeg with St. Boniface, a Winnipeg community across the Red River. It derived its name from the connecting Boulevard Provencher (Provencher Boulevard). The vehicular bridge serves Route 57 and is a main connector from downtown Winnipeg to most of the eastern communities in Winnipeg. The speed limit on the bridge is 50 km/h (31 mph). Bridge history There have been a total of three bridges (aka Red River Bridges), as well as a ferry, linking Winnipeg from the then-eastern end of Broadway with St. Boniface from the western end of Provencher Boulevard. The current-day Provencher Bridge succeeds the ferry and the previous two bridges. Ferry The first way of crossing the Red River was by the Notre Dame Street (Pioneer Avenue) fer ...

Esplanade Riel
Esplanade Riel is a pedestrian bridge located in Winnipeg, Manitoba. It was named in honour of Louis Riel. It is a side-spar cable-stayed bridge which spans the Red River connecting downtown Winnipeg with St. Boniface; it is paired with a vehicular bridge, the Provencher Bridge. The bridge includes an architectural composite tower that is prestressed with a cantilevered and stayed semi-circular plaza area at the base of the tower. The plaza provides space for commercial activities and as well as a restaurant. The Esplanade Riel is the only bridge with a restaurant in North America. Its first restaurant was a Salisbury House. Salisbury House is a chain restaurant local to Winnipeg. The next tenant was Chez Sophie sur le pont (on the bridge), which opened in the summer of 2013 and closed in February 2015. The Esplanade Riel has become a landmark and is used in many promotional materials. Opened to foot traffic in 2003 and having a grand opening in the summer of 2004, the Espla ...

Joint-stock Company
A joint-stock company is a business entity in which shares of the company's stock can be bought and sold by shareholders. Each shareholder owns company stock in proportion, evidenced by their shares (certificates of ownership). Shareholders are able to transfer their shares to others without any effects to the continued existence of the company. In modern-day corporate law, the existence of a joint-stock company is often synonymous with incorporation (possession of legal personality separate from shareholders) and limited liability (shareholders are liable for the company's debts only to the value of the money they have invested in the company). Therefore, joint-stock companies are commonly known as corporations or limited companies. Some jurisdictions still provide the possibility of registering joint-stock companies without limited liability. In the United Kingdom and in other countries that have adopted its model of company law, they are known as unlimited companies. In ...

Dominion Bridge Company
Dominion Bridge Company Limited was a Canadian steel bridge constructor originally based in Lachine, Quebec. From the core business of steel bridge component fabrication, the company diversified into related areas such as the fabrication of holding tanks for pulp mills and skyscraper framing. Other Canadian plants were located in Amherst, NS, Toronto, ON, Winnipeg, MB, Regina, SK, Saskatoon, SK, Calgary, AB, Edmonton, AB, Richmond, BC and Burnaby, BC. In the 1960s and 1970s, Dominion Bridge expanded internationally and renamed itself AMCA International (AMCA name effective June 1, 1981). This name was later changed to United Dominion Industries. To keep name recognition alive, the company continued to call its Canadian division 'Dominion Bridge'. Between 1979-1988, the company's Lachine plant operated under the auspices of a subsidiary called Dominion Bridge-Sulzer Inc., which was co-owned by AMCA International and Sulzer Inc.

Strauss Bascule Bridge Company
Joseph Baermann Strauss (January 9, 1870 – May 16, 1938) was an American structural engineer who revolutionized the design of bascule bridges. He was the chief engineer of the Golden Gate Bridge, a suspension bridge. Life, beginnings and death He was born in Cincinnati, Ohio, to an artistic family of German-Jewish ancestry. His mother was a pianist, and his father, Raphael Strauss, was a writer and painter. He graduated from the University of Cincinnati in 1892 with a degree in civil engineering. He served as both class poet and president, and was a brother of the Sigma Alpha Epsilon fraternity. Strauss had many hobbies. One of these included poetry. After completion of the Golden Gate Bridge he returned to his passion of poetry and wrote his most recognizable poem "The Mighty Task is Done". He also wrote "The Redwoods", and his "Sequoia" can still be purchased by tourists visiting the California redwoods. He died in Los Angeles, California, just one year after the Golden Ga ...

Double Leaf 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 sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viaduct
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Icebreaker
A river icebreaker is an icebreaker specially designed to operate in shallow waters such as rivers and estuaries An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environmen ..., and often able to pass through canals and under bridges. As published by the American Society of Civil Engineers almost a century ago, "On some rivers, particularly where melting first takes place on the upper river, as on the Oder and Weichsel in Germany, the formation of ice jams is a frequent cause of floods." River icebreakers can operate in any navigable waterway to prevent such ice jams. Various river icebreakers, from smaller vessels to the nuclear-powered shallow draft icebreakers ''Taymyr''-class ''Vaygach'' and ''Taymyr'', [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toll Bridge
A toll bridge is a bridge where a monetary charge (or '' toll'') is required to pass over. Generally the private or public owner, builder and maintainer of the bridge uses the toll to recoup their investment, in much the same way as a toll road. History The practice of collecting tolls on bridges harks back to the days of ferry crossings where people paid a fee to be ferried across stretches of water. As boats became impractical to carry large loads, ferry operators looked for new sources of revenue. Having built a bridge, they hoped to recoup their investment by charging tolls for people, animals, vehicles, and goods to cross it. The original London Bridge across the river Thames opened as a toll bridge, but an accumulation of funds by the charitable trust that operated the bridge ( Bridge House Estates) saw that the charges were dropped. Using interest on its capital assets, the trust now owns and runs all seven central London bridges at no cost to taxpayers or users. ...

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. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct 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 strength to maintain its own shape, and th ...

Swing Span
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or ...
