Congratulations to the winners of the Trivia Game!
Daniel
Collete, Katherine Richardson, Diane
Leroux, Fiasal Dosani and Steve Bilyea
were the first five people to submit
the correct response for the trivia
game in the last issue. The photo corresponds
to The Quebec Bridge (Pont de Québec
in French). Thank you to all the other
participants who submitted their guess.
The Quebec Bridge crosses the lower
Saint Lawrence River to the west of Quebec City, and Lévis, Quebec.
It is a riveted steel truss structure and is 987 metres (3,239 feet)
long, 29 metres (94 ft) wide, and 104 metres (340 ft) high. Each
cantilever span is 580 feet long. The Quebec Bridge accommodates
1 rail line, 3 lanes of automotive traffic and 2 pedestrian walkways.
It is the longest cantilever bridge span in the world.
History
The first bridge South Anchor Arm
and a portion of the Center Span failed catastrophically August
29, 1907, due to design changes during construction, which significantly
increased the weight of the structure. In September 1916, the pre-fabricated
Center Span fell, while being raised into position. The second Quebec
Bridge was completed in September 1917, at a total cost of $25 Million
Dollars.
The Quebec Bridge was declared
a historic monument in 1987, by
the Canadian & American Society
of Civil Engineers and a National
Historic Site on January 24, 1996
by the Department of Canadian Heritage. It is owned by the Canadian
National Railway since 1993.
