Niagara River
The Rainbow Bridge at Niagara Falls is an arch bridge made of steel, which crosses the gorge of the Niagara River. It connects the cities of Niagara Falls, New York, on the east and Niagara Falls, Ontario, west of the border between the United States and Canada.
History
The Rainbow Bridge was built near the earlier Honeymoon Bridge ( Upper Steel Arch Bridge ), whose collapse was caused on 27 January 1938 by an ice barrier in the river. A joint Canadian and U.S. Commission had already deliberated over a new building when the collapse made the matter urgent. King George VI. and Queen Elizabeth dedicated the building site during their visit to the Niagara Falls on the occasion of the visit trip to Canada in 1939; A memorial stone was erected to mark the occasion. Construction began in May 1940, the official opening of the bridge took place on 1 November 1941.
Location
The Canadian portion of the bridge by the Ontario Ministry of Transportation has been designated as part of Highway 420, although it is separated from the rest of the highway by a regional road. On the U.S. side the road is known across the river by the New York State Department of Transportation as the New York State Reference Route 955A, but is not signposted as such. The New York State Routes 104 and 384 and the northern section of the Robert Moses State Parkway terminating at the last intersection before the bridge and none of these highways leads up to the bridge. U.S. Highway 62 terminates two blocks north on State Route 104
The complex on the Canadian side of the Rainbow Tower is one in which a carillon is, which is several times a day to hear.
The bridge is not approved for heavy goods vehicles, trucks have to drive across the Peace Bridge or the Lewiston- Queenston Bridge.
Description
Rainbow Bridge crosses the gorge of the Niagara River on the Canadian side and the leading along the high banks of River Road and the Robert Moses Parkway on the American side. There are extensive plazas are located at the two ends of the bridge for border clearance. It has two lanes in each direction and on the south side of the Niagara Falls facing a 3.3 m wide walkway. The Rainbow Bridge is a clamped steel arch bridge with aufgeständerter roadway. The entire bridge structure including the bridge spans over the two roads is 442 m (1450 ft ) long. The arch bridge is framed by reinforced concrete bridge spans with arches on tall pillars that connect the bridge deck with the high banks. This is followed on both sides of a plate girder bridge over the road to. The arch consists of two steel box girders with a height of 3.65 m at a lateral distance of 17 m, which are stiffened by triangle organizations against each other. The span of the arch of the bridge is 289.5 m (950 ft). The large concrete blocks that make up the fighters for the arches are 15 meters from the shore at a height of 15 m above the river also water, so they can not be reached by larger ice jams. The upper edge of the bridge deck is 61.5 m m above the river.
The design of the bridge comes from the engineering firm Waddell & Hardesty, that 21 years later under his name Hardesty & Hanover created the plans for the Lewiston- Queenston Bridge. Although the Lewiston- Queenston Bridge is not a direct copy of the Rainbow Bridge bridge, but has similar dimensions and looks almost exactly.
