Rosedale Valley Bridge
The Rosedale Valley Bridge (also called the Rosedale Ravine Bridge) is a covered arch bridge in the northeast of Downtown Toronto, Ontario. Built in 1966 by architect John B. Parkin (now part of Delcan Corporation), the concrete bridge carries Line 2 trains of the subway across the Rosedale Ravine. The eastern end of the Rosedale Valley Bridge is situated at the west end of Castle Frank station. The bridge itself runs on the north side of and almost parallel to the Rosedale section of the Prince Edward Viaduct. The viaduct opened in 1918 and had a lower deck over its entire length designed for rail transport. When the first phase of the Bloor subway line opened, its tracks used the lower deck of the main phase across the Don River Valley to the east as originally intended. However, since the approach curves leading to the Rosedale section would be too sharp for the trains, the dedicated Rosedale Valley Bridge was built to carry them, and the lower deck of the original viaduct ...

Line 2 Bloor–Danforth
Line 2 Bloor–Danforth is a subway line in the Toronto subway system, operated by the Toronto Transit Commission (TTC). It has 31 stations and is in length. It opened on February 26, 1966, and extensions at both ends were completed in 1968 and again in 1980. The line runs primarily a few metres north of Bloor Street from its western terminus at Kipling Avenue with a direct connection to the Kipling GO Station to the Prince Edward Viaduct east of Castle Frank Road, after which the street continues as Danforth Avenue and the line continues running a few metres north of Danforth Avenue until just east of Main Street, where it bends northeasterly and runs above-grade until just east of Warden station, where it continues underground to its eastern terminus, slightly east of Kennedy Road on Eglinton Avenue, which has a direct connection to the Kennedy GO Station. The subway line is closed nightly for maintenance, during which Blue Night Network bus routes provide service along th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Don River (Ontario)
The Don River is a watercourse in southern Ontario that empties into Lake Ontario, at Toronto Harbour. Its mouth was just east of the street grid of the town of York, Upper Canada, the municipality that evolved into Toronto, Ontario. The Don is one of the major watercourses draining Toronto (along with the Humber, and Rouge Rivers) that have headwaters in the Oak Ridges Moraine. The Don is formed from two rivers, the East and West Branches, that meet about north of Lake Ontario while flowing southward into the lake. The area below the confluence is known as the "lower Don", and the areas above as the "upper Don". The Don is also joined at the confluence by a third major branch, Taylor-Massey Creek. The Toronto and Region Conservation Authority (TRCA) is responsible for managing the river and its surrounding watershed. Toponymy In 1788, Alexander Aitkin, an English surveyor who worked in southern Ontario, referred to the Don River as ''Ne cheng qua kekonk''. Elizabeth Simcoe, wif ...

Concrete Bridges In Canada
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges In Toronto
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. Etymology The ''Oxford English Dictionary'' traces the origin of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leaside Bridge
The Leaside Bridge, formerly the East York Leaside Viaduct, and officially commemorated as the Confederation Bridge, spans the Don River in the City of Toronto, Ontario. The Truss bridge carrying Millwood Road was built to connect the then Town of Leaside, including Thorncliffe Park, to the then Township of East York, and was completed on October 29, 1927. The construction time of only 10 months was record breaking at the time. History During the 1920s, as the new communities surrounding Toronto grew rapidly, several bridges were constructed to overcome the barrier of the Don Valley. Among these were the Vale of Avoca ( St. Clair Avenue east of Yonge Street) and the East York – Leaside Viaduct. The town of Leaside, built by Canadian Northern Railway in the late teens and early 1920s, sought to attract investors and homebuyers. A connection over the Don Valley to the town of Todmorden Mills and on to Toronto would provide this. Sod was turned in mid-December and active co ...

Beam Bridge
Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. No moments are transferred throughout the support, hence their structural type is known as '' simply supported''. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid across a stream. Bridges designed for modern infrastructure will usually be constructed of steel or reinforced concrete, or a combination of both. The concrete elements may be reinforced, prestressed or post-tensioned. Such modern bridges include girder, plate girder, and box girder bridges, all types of beam bridges. Types of construction could include having many beams side by side with a deck across the top of them, to a main beam either side supporting a deck between them. The main beams could be I-beams, trusses, or box girders. They could be half-through, or braced across the top to create a through bridge. Because no moments ...

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 ...

Glen Road Bridge
A glen is a valley, typically one that is long and bounded by gently sloped concave sides, unlike a ravine, which is deep and bounded by steep slopes. Whittow defines it as a "Scottish term for a deep valley in the Highlands" that is "narrower than a strath".. The word is Goidelic in origin: ''gleann'' in Irish and Scottish Gaelic, ''glion'' in Manx. The designation "glen" also occurs often in place names. Etymology The word is Goidelic in origin: ''gleann'' in Irish and Scottish Gaelic, ''glion'' in Manx. In Manx, ''glan'' is also to be found meaning glen. It is cognate with Welsh ''glyn''. Examples in Northern England, such as Glenridding, Westmorland, or Glendue, near Haltwhistle, Northumberland, are thought to derive from the aforementioned Cumbric cognate, or another Brythonic equivalent. This likely underlies some examples in Southern Scotland. As the name of a river, it is thought to derive from the Irish word ''glan'' meaning clean, or the Welsh word ''gleindid' ...
