Let’s compare our bridge with another
The Millau viaduct in France, in addition to being the tallest bridge in the world (with its tallest mast reaching 343 metres), is arguably also one of the world’s most elegant and beautiful structures. I think the world records it holds for its construction might serve as an apt comparison for Victoria’s famous bridge.
Crossing the Tarn river and its entire gorge, Millau’s “engineering marvel” viaduct has seven central piers, from which is suspended the road deck, via tensioned cables.
Users pay about eight euros to drive the 2,460-metre-long bridge, which took three years to construct, at a cost of about $578 million.
Our own bridge will be, according to the City of Victoria’s official site, the “largest single-leaf bascule bridge in Canada — and one of the largest in the world — creating a new iconic structure and destination within Victoria’s Inner Harbour.” About 1/60th the span of the Millau, our 41-metrelong bridge is, by the most recent calculations, set to cost $105 million.
By the time the new Johnson Street Bridge replacement opens in 2018, it will have taken about two years longer than the three years it took to complete the world’s tallest bridge. While the viaduct cost about $235,000 per metre, our short bascule span will cost about 10 times that, at a little over $2.56 million per metre.
I wonder whether additional records we aim to set are for construction duration or world’s greatest boondoggle. Lori Waters Victoria
