The Burrard Bridge (sometimes referred to as the Burrard Street Bridge) is a five-lane, Art Deco style, steel truss bridge constructed in 1930-1932 in Vancouver, British Columbia, Canada.〔 〕〔 〕 The high, five part bridge on four piers spans False Creek, connecting downtown Vancouver with Kitsilano via connections to Burrard Street on both ends. It is one of three bridges crossing False Creek. The other two bridges are the Granville Bridge, three blocks or to the southeast, and the Cambie Street Bridge, about 11 blocks or to the east. In addition to the vehicle deck, the Burrard Bridge has sidewalks on both sides, wide, the northern one (with a view of English Bay and West Vancouver) for pedestrians and the southern one (with a view of False Creek) now dedicated to cyclists. The architect of the Burrard Bridge was George Lister Thornton Sharp, the engineer John R. Grant. The bridge's two close approach spans are Warren trusses placed below deck level, while its central span is a Pratt truss placed above deck level to allow greater clearance height for ships passing underneath. The central truss is hidden when crossing the bridge in either direction by vertical extensions of the bridge's masonry piers into imposing concrete towers, connected by overhead galleries, which are embellished with architectural and sculptural details that create a torch-like entrance of pylons. Busts of Captain George Vancouver and Sir Harry Burrard-Neale in ship prows jut from the bridge’s superstructure (a V under Vancouver’s bust, a B under Burrard’s). Unifying the long approaches and the distinctive central span are heavy concrete railings, originally topped with decorative street lamps. These pierced handrails were designed as a kind of visual shutter (stroboscopic effect), so that at a speed of 50 km/h motorists would see through them with an uninterrupted view of the harbour. The effect works at speeds from about 40 to 64 km/h.〔 ==History== The Burrard Bridge, opened July 1, 1932, was built to provide a high-level crossing from Vancouver to the southwestern neighbourhoods in Kitsilano, by connecting Burrard Street to Cedar Street. After completion, Burrard was extended through to the base of downtown and Cedar Street disappeared. At the opening ceremony, entertainment was provided by two bands, the Kitsilano Boy's Band and the Fireman's Band. An RCAF seaplane flew under the bridge and later a sugar replica of the bridge was unveiled at the civic reception in the Hotel Vancouver. G.L. Thornton Sharp, of Sharp and Thompson, was the architect responsible for the distinctive towers on the bridge and its middle galleries. "Both central piers," Sharp told a reporter, "were designed and connected with an overhead gallery across the road. This helped to mask the network of steel in the truss from the two approaches, and has been treated as an entrance gateway to the city." Along their other axis, the full height of the piers above the water also serve to frame a sea entrance gateway, notably for pleasure craft: "by sea and land we prosper". The piers have provision for a rapid transit vertical lift span beneath the highway deck, never installed. 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「Burrard Bridge」の詳細全文を読む スポンサード リンク
