Rouge River Bridge
Rouge River Bridge is a series of spans carrying traffic on Highway 401 (Ontario) over the Rouge River (Ontario). It is technically not a single bridge, but rather several spans of highway overpasses over the Rouge River. Parts of the original bridges (built 1941-1942) during the initial construction of Highway 401 remain next to the spans added after the 1970s. The inner or express spans were built in 1971 and the outer or collector spans were completed in 1994 as part of the widening of the highway between Pickering and Scarborough. Both spans are Girder bridges. The spans carry 12 lanes of traffic in total, and run parallel to a section of Kingston Road that spans across the Rouge River on the north side. This is one of the least busy sections of the Highway 401 in Toronto carrying around 230,000 vehicles on average per weekday.

Rouge River (Toronto)
The Rouge River is a river in Markham, Pickering, Richmond Hill and Toronto in the Greater Toronto Area of Ontario, Canada. The river flows from the Oak Ridges Moraine to Lake Ontario at the eastern border of Toronto, and is the location of Rouge Park, the only national park in Canada within a municipality. At its southern end, the Rouge River is the boundary between Toronto and southwestern Pickering in the Regional Municipality of Durham. History The Rouge River is part of the Carolinian life zone that is found in Southern Ontario. After the eradication of both the Petun and the Wyandot (Huron), Senecas from New York attempted to establish/expand their fur trade activities by establishing a village named ''Gandechiagaiagon'' (recorded variously as "Gandatsekiagon", "Ganatsekwyagon", "Gandatchekiagon", or "Katabokokonk"), meaning "sand-cut" at the mouth of Rouge River. According to a 1796 list by English surveyor Augustus Jones, the Mississauga name for the river was ''Gic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highway 401 (Ontario)
King's Highway 401, commonly referred to as Highway 401 and also known by its official name as the Macdonald–Cartier Freeway or colloquially referred to as the four-oh-one, is a controlled-access 400-series highway in the Canadian province of Ontario. It stretches from Windsor in the west to the Ontario–Quebec border in the east. The part of Highway 401 that passes through Toronto is North America's busiest highway, and one of the widest. Together with Quebec Autoroute 20, it forms the road transportation backbone of the Quebec City–Windsor Corridor, along which over half of Canada's population resides. It is also a ''Core Route'' in the National Highway System of Canada. The route is maintained by the Ministry of Transportation of Ontario (MTO) and patrolled by the Ontario Provincial Police. The speed limit is throughout its length, with the only exceptions the posted limit westbound in Windsor and in most construction zones, along with a speed limit between ...

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] |

Hogg's Hollow Bridge
Hoggs Hollow Bridge, originally known as the Yonge Boulevard Viaduct, is a set of four separate highway bridges that span the West Branch of the Don River Valley in Toronto, Ontario, Canada, and carries 14 lanes of Highway 401. The four structures are the busiest multi-span bridge crossing in North America, surpassing the Brooklyn Bridge. Description The Hoggs Hollow Bridge has a 14-lane cross section: 6 collector lanes, 8 express lanes. The road surface and bridge decks require constant maintenance due to the wear and tear from high traffic volumes. Since 2001, an Ontario tall-wall concrete barrier has replaced the steel guide–rail in the median separating eastbound and westbound traffic. The late 1960s conventional truss lights have been replaced by high-mast lighting. Starting from 2002, the westbound collector lanes on the outer north bridge have also undergone rehabilitation (replacing road surface, guard rails and/or concrete barriers). The westbound collector traf ... [...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 ...

Toronto
Toronto ( ; or ) is the capital city of the Canadian province of Ontario. With a recorded population of 2,794,356 in 2021, it is the most populous city in Canada and the fourth most populous city in North America. The city is the anchor of the Golden Horseshoe, an urban agglomeration of 9,765,188 people (as of 2021) surrounding the western end of Lake Ontario, while the Greater Toronto Area proper had a 2021 population of 6,712,341. Toronto is an international centre of business, finance, arts, sports and culture, and is recognized as one of the most multicultural and cosmopolitan cities in the world. Indigenous peoples have travelled through and inhabited the Toronto area, located on a broad sloping plateau interspersed with rivers, deep ravines, and urban forest, for more than 10,000 years. After the broadly disputed Toronto Purchase, when the Mississauga surrendered the area to the British Crown, the British established the town of York in 1793 and later designat ...

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 ...

Ontario Ministry Of Transportation
The Ministry of Transportation (MTO) is the provincial ministry of the Government of Ontario that is responsible for transport infrastructure and related law in Ontario. The ministry traces its roots back over a century to the 1890s, when the province began training Provincial Road Building Instructors. In 1916, the Department of Public Highways of Ontario (DPHO) was formed and tasked with establishing a network of provincial highways. The first was designated in 1918, and by the summer of 1925, sixteen highways were numbered. In the mid-1920s, a new Department of Northern Development (DND) was created to manage infrastructure improvements in northern Ontario; it merged with the Department of Highways of Ontario (DHO) on April 1, 1937. In 1971, the Department of Highways took on responsibility for Communications and in 1972 was reorganized as the Ministry of Transportation and Communications (MTC), which then became the Ministry of Transportation in 1987.
