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 The late 1960s conventional truss lights have been replaced by high-mast lighting.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] |
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 ...

Cul-de-sac
A dead end, also known as a cul-de-sac (, from French for 'bag-bottom'), no through road or no exit road, is a street with only one inlet or outlet. The term "dead end" is understood in all varieties of English, but the official terminology and traffic signs include many different alternatives. Some of these are used only regionally. In the United States and other countries, ''cul-de-sac'' is often not an exact synonym for ''dead end'' and refers to dead ends with a circular end, allowing for easy turning at the end of the road. In Australia and Canada, they are usually referred to as a ''court'' when they have a bulbous end. Dead ends are added to road layouts in urban planning to limit through-traffic in residential areas. While some dead ends provide no possible passage except in and out of their road entry, others allow cyclists, pedestrians or other non-automotive traffic to pass through connecting easements or paths, an example of filtered permeability.

Bridges Completed In 1960
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 wo ... [...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 ...

Sheppard Avenue Bridge
Sheppard Avenue Bridge is an under deck Truss bridge that spans the Don River on Sheppard Avenue West, just east of Bathurst Street in Toronto, Ontario, Canada. Built in 1954, the bridge has a scenic view of the West Don River and Earl Bales Park. The current bridge replaced an old concrete bridge that was damaged during Hurricane Hazel and required cars to descend down the valley. The upper deck carries four lanes of traffic. There is a water main in the steel sub-structure. In April 2006, a small section of the road collapsed due to a break in the 50-year-old water main carried below. The bridge was out of commission for three weeks. The bridge is the last major bridge to span the West Don River before it is diverted under most roads north of Sheppard with metal or concrete culverts. Several smaller concrete bridges traverse over the East Don River (with one larger bridge on Eglinton Avenue near the Don Valley Parkway) northwards towards the city limits at Steeles Avenue ...

List Of Bridges In Canada
This is a list of bridges and viaducts in Canada, including those for pedestrians and vehicular traffic. Historical and architectural interest bridges There are only a few covered bridges left in Canada compared to all those that were built in the past. In the Quebec province, if we already counted 1200 in the last century, today there are only 88 remaining. In New Brunswick, 58 covered bridges have been identified. Major road and railway bridges The Canada's longest bridge is the Confederation Bridge in the Gulf of St. Lawrence with a total of between abutments, it's also the world's longest bridge over ice-covered water. More than 5,000 local workers helped with the project, which cost about $1 billion. The Quebec Bridge has been the longest cantilever bridge span in the world since 1917, measuring between its two piles. It helds the record of all-categories longest span in the world until the opening of the Ambassador Bridge, it's the last bridge that broke such a rec ...

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.

Ministry Of Transportation Of Ontario
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.

York Mills Road
York Mills Road is an east-west route in Toronto, Ontario, Canada named for the historic village of York Mills that was located on the hill immediately north of today's intersection of York Mills Road and Yonge Street. The village of York Mills is distinguished from the 1920s subdivision to the south known as Hoggs Hollow. "York" refers to York Township and "Mills" refers to the gristmills and sawmills that once operated (1804–1926) in the valley through which the Don River runs. York Mills runs east of Yonge Street and ends at Victoria Park Avenue. Near Victoria Park, most of the traffic follows Parkwoods Village Drive in connection to Ellesmere Road. To the west, York Mills Road becomes Wilson Avenue. These roads form a parallel alternative to the nearby Highway 401. Based on early surveys of Toronto and York County, York Mills Road would have been the Fifth Concession. In the 1970s, when the Toronto Transit Commission extended the Line 1 Yonge subway line north from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
