Louis-Hippolyte Lafontaine Bridge–Tunnel
The Louis-Hippolyte Lafontaine Bridge–Tunnel () is a highway bridge–tunnel running over and beneath the Saint Lawrence River. It connects the Montreal borough of Mercier–Hochelaga-Maisonneuve with the south shore of the river at Longueuil, Quebec. Named after Lower Canada political reformer Louis-Hippolyte Lafontaine, the Lafontaine Tunnel is an immersed tube structure, measuring long. It carries the Autoroute 25 expressway and passes beneath the main shipping channel in the Saint Lawrence River, immediately downstream from the Saint Lawrence Seaway. It surfaces on Île Charron ( Îles de Boucherville at Exit 1 of Autoroute 25), then continues by bridge to Longueuil. The bridge-tunnel sees about 120,000 daily crossings, of which 13% are trucks. Construction began in 1963, and opening day was March 11, 1967. History In 1960, the construction of the Trans-Canada Highway (TCH) through Quebec from the Ontario border to Rivière-du-Loup was announced. In Montreal, to avo ...

Trans-Canada Highway
The Trans-Canada Highway (Canadian French, French: ; abbreviated as the TCH or T-Can) is a transcontinental federal–provincial highway system that travels through all ten provinces of Canada, from the Pacific Ocean on the west coast to the Atlantic Ocean on the east coast. The main route spans across the country, one of the longest routes of its type in the world. The highway system is recognizable by its distinctive white-on-green maple leaf route shield, route markers, although there are small variations in the markers in some provinces. While by definition the Trans-Canada Highway is a highway ''system'' that has several parallel routes throughout most of the country, the term "Trans-Canada Highway" often refers to the main route that consists of Highway 1 (British Columbia, Alberta, Saskatchewan, and Manitoba), Highways 11 & 17/417 (Ontario), Autoroutes 40, 25, 20, 85 & 185 (Quebec), Highway 2 (New Brunswick), Highways 104 and 105 (Nova Scotia), and ...

List Of Bridges In Montreal
Like most major cities, Montreal needs easy highway access from its suburbs and surrounding areas. However, because Montreal was built on Island of Montreal, an island surrounded by three rivers, it can be entered by land only on a bridge or through a tunnel. Although the city was founded in 1642, it was not until 1847 that the first fixed link to the outside was established when a wooden bridge was built across Rivière des Prairies to Île Jésus, on the site of what is now Ahuntsic Bridge. Another bridge was built immediately afterward, a few kilometers west, which became Lachapelle Bridge, and another in 1849, Pont des Saints-Anges, to the east. The latter bridge collapsed in the 1880s and was never rebuilt. With the advent of the railroad, Montreal got a fixed link to the mainland; in 1854 railroad bridges were built in Sainte-Anne-de-Bellevue, across both channels of the Ottawa River, linking Montreal Island to Ontario and the Vaudreuil-Soulanges peninsula through Perrot Isla ...

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. In Quebec, despite over 1,200 existing in the last century, today there are only 88 remaining. In New Brunswick, 58 covered bridges have been identified. Major road and railway bridges 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 held 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 record before suspension bridges hold the award by far. It was de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prestressed Concrete
Prestressed concrete is a form of concrete used in construction. It is substantially prestressed (Compression (physics), compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. Post-tensioned concreted is "structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads." It was patented by Eugène Freyssinet in 1928. This compression is produced by the Tension (physics), tensioning of high-strength ''tendons'' located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire Wire rope, strands or threaded bars that are most commonly made from high-tensile steels, carbon fiber or aramid fiber. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concre ...

Dry Dock
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History China The use of dry docks in China goes at least as far back as the 10th century A.D. In 1088, Song dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Europe Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous '' Tessarakonteres'' rowing ship. However a more recent survey by Goodchild and Forbes does not substantiate its existence. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. Renaiss ...

Expo 67
The 1967 International and Universal Exposition, commonly known as Expo 67, was a general exhibition from April 28 to October 29, 1967. It was a category one world's fair held in Montreal, Quebec, Canada. It is considered to be one of the most successful World's Fairs of the 20th century with the most attendees to that date and 62 nations participating. It also set the single-day attendance record for a world's fair, with 569,500 visitors on its third day. Expo 67 was Canada's main celebration during its Canadian Centennial, centennial year. The fair had been intended to be held in Moscow, to help the Soviet Union celebrate the Russian Revolution of 1917, Russian Revolution's 50th anniversary; however, for various reasons, the Soviets decided to cancel, and Canada was awarded it in late 1962. The project was not well supported in Canada at first. It took the determination of Montreal's mayor, Jean Drapeau, and a new team of managers to guide it past political, physical and temp ...

Longue-Pointe
Longue-Pointe () was a Montreal List of neighbourhoods in Montreal, neighbourhood now located in the borough of Mercier-Hochelaga-Maisonneuve. The neighborhood was permanently divided by the construction of the Louis-Hippolyte Lafontaine Bridge-Tunnel, Louis-Hippolyte Lafontaine Tunnel. Most of its territory is now part of the Mercier-Ouest while some of the area that fell east of the highway is now within Mercier-Est.

Stream Bed
A streambed or stream bed is the bottom of a stream or river and is confined within a Stream channel, channel or the Bank (geography), banks of the waterway. Usually, the bed does not contain terrestrial (land) vegetation and instead supports different types of aquatic vegetation (aquatic plant), depending on the type of streambed material and water velocity. Streambeds are what would be left once a stream is no longer in existence. The beds are usually well preserved even if they get buried because the banks and canyons made by the stream are typically hard, although soft sand and debris often fill the bed. Dry, buried streambeds can actually be underground water pockets. During times of rain, sandy streambeds can soak up and retain water, even during dry seasons, keeping the water table close enough to the surface to be obtainable by local people. The nature of any streambed is always a function of the flow dynamics and the local geologic materials. The climate of an area wil ...
