The Victoria Bridge ((フランス語:Pont Victoria)), previously known as Victoria Jubilee Bridge, is a bridge over the St. Lawrence River, linking Montreal, Quebec, to the south shore city of Saint-Lambert. Opened in 1859, originally as a tubular bridge designed by Robert Stephenson, the bridge was the first to span the St. Lawrence River, and as such is an important historic bridge in Canada. It remains in use to this day, carrying both road and rail traffic, with rails in the middle and roadways (part of Route 112) on both sides. It is actively used by the Canadian National Railway on its Halifax to Montreal main line. It is a major contributor to Montreal's role as a continental hub in the North American rail system. Its designation for the Canadian National Railway (CNR commonly known as CN) is Mile 71.40 Subdivision St-Hyacinthe. Originally named the Great Victoria Bridge in honour of Queen Victoria, it was officially rededicated as the Victoria Jubilee Bridge following renovations in 1897 (A.D. MDCCCXCVII). It was returned to the name Victoria Bridge (フランス語:Pont Victoria) in 1978.〔("Victoria, Pont." ) Commission de toponymie du Québec. Accessed 5 July 2011.〕 The bridge is approximately long, and includes 24 ice-breaking piers. ==History== Prior to the construction of the Victoria Bridge, it was difficult and at times impossible to cross the St. Lawrence River during the long winter season, as freeze up and thawing in the fall and spring made for treacherous conditions. Crossings took place by boat during the summer, and by walking or riding a sleigh or cart over the frozen river in winter, along routes cleared of snow to facilitate passage. A site for the bridge was selected by the eminent Canadian engineer Thomas Keefer. Erected between 1854 and 1859, Victoria Bridge was officially inaugurated by Albert Edward, the Prince of Wales on August 25, 1860. The first freight train however had already passed over the bridge on December 12, 1859, and the first passenger train had crossed the bridge five days later on December 17. Queen Victoria had been invited to attend the opening of the bridge, but she declined the invitation and instead sent her eldest son, the Prince of Wales and heir to her throne. When completed, it was the longest bridge in the world. During its peak construction years six steamboats, 72 barges, 3,040 men (of which there were several children between the ages of 8 and 12), 144 horses, and four locomotive engines were required to erect it at a cost of $6,600,000. The construction of the bridge was tied directly with that of the Grand Trunk Railway, a system headquartered in Britain which had been formed in 1852 with the support of the colonial government of the United Province of Canada to connect the Great Lakes with an ice-free port on the Atlantic Ocean (at Portland, Maine). The chief engineer was James Hodges. The original deck was a long structural metal tube (a tubular bridge) made of prefabricated wrought iron sections made in England and shipped transatlantic. The structure was designed by Robert Stephenson(son of George Stephenson and the builder of the famed ''Rocket'' locomotive), and Alexander McKenzie Ross. The contractors were the English partnership of Peto, Brassey and Betts, who completed the bridge shortly after Stephenson's death in 1859. In 1897–1898, the metal tube from 1860 was replaced by metal trusses, common at the time. To minimize traffic disruptions, the trusses were assembled around the tube, which permitted the tube to continue service to train traffic. The tube was then demolished. The stone piers from 1860, slightly altered in 1897, still testify to the excellent original engineering. Between October 30, 1909 and October 13, 1956, the Montreal and Southern Counties Railway ran interurban streetcars on the Northern shoulder of the bridge. The line connected Granby and Montreal, with a later branch serving Longueuil. The St. Lambert Diversion around the St. Lambert Locks was added in 1958 as part of the St. Lawrence Seaway project. This secondary bridge over the canal, south of the main bridge, also carries both road and rail, and is used when a ship is passing under the original alignment. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Victoria Bridge (Montreal)」の詳細全文を読む スポンサード リンク
