The Champlain Bridge ((フランス語:Pont Champlain)) is a steel truss cantilever bridge with approach viaducts constructed of prestressed concrete beams supporting a prestressed concrete deck paved with asphalt. The bridge crosses the Saint Lawrence River and Saint Lawrence Seaway, connecting the Montreal boroughs of Verdun and Le Sud-Ouest to Brossard on the South Shore. The bridge, with approaches, is approximately long. When the project began, it was designated as the "Nuns' Island Bridge" because it crosses over Nuns' Island. In 1958, it was officially named the Champlain Bridge in honour of the explorer Samuel de Champlain, who founded Quebec City in 1608. Together with the Jacques Cartier Bridge, it is administered by the Jacques Cartier and Champlain Bridges Incorporated (JCCBI), a Canadian Crown Corporation which reports to Infrastructure Canada. With nearly 160,000 daily crossings, the Champlain Bridge is the busiest single-span bridge in Canada (Hogg's Hollow Bridge is the busiest overall). ==Specifications== The Champlain Bridge project was undertaken in 1955 and construction proceeded between 1957 and 1962. The bridge carries six lanes of vehicle traffic; three in each direction. During rush hour one lane of those heading off the island in the morning, and onto the island in the evening, is used as a reserved bus lane for buses to be able to head in the opposite direction. The bridge was opened to traffic in stages as the approaches were completed between June, 1962 and September, 1964. It was subsequently connected to the Bonaventure Expressway, which is part of the north approach to the bridge. The expressway was opened to traffic on April 21, 1967. Approximately 49 million vehicles cross the Champlain Bridge every year, and 196 million people making it one of the busiest bridges in the world. *Total length of crossing complex: *Total bridge length including approaches: * *Length: abutment to abutment: * *Link of viaduct to Section 1: * *Center main cantilevered span: * *Wellington Street approach: *Bonaventure Expressway: Just upstream from the bridge is an ice boom, the Champlain Bridge Ice Control Structure. 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「Champlain Bridge, Montreal」の詳細全文を読む スポンサード リンク
