It’s time for the Liberal government to explain what might happen next. The Port Mann bridge and highway project cost $3.3 billion but we’ve seen that provided no protection from ice falls. What assurance do we have that other known problems of cable stayed bridges were not similarly ignored?
From the archives of the New York Times:
A FUROR has erupted in the world of bridge engineering over the long-term reliability of an innovative design that has come to dominate the modern generation of great bridges, all but replacing the traditional suspension bridge.
Two experts have conducted an international survey of these new bridges, known as cable-stayed bridges, and they say that their inspections revealed widespread corrosion -premature and potentially dangerous – in the cables that hold up the roadways.
”There’s a cancer in these bridges,” one of the experts, Stewart C. Watson, said in an interview. Last Friday, he told a group of experts on bridge safety in New York, ”After looking at 100 of these bridges, we’re scared to death.”
In Germany, where the the cable-stay design was invented, bridges that were meant to last for many decades have had to be shut down so that corroded cables could be replaced. ”We were just shocked to see new bridges, 4 to 10 years old, with tremendous corrosive degradation of the primary cables,” Mr. Watson said…
It is worth noting that in days of not-net-zero, TIC Grant Main eked out a 20% raise in fiscal 2012, about $3,800 monthly. He didn’t make out as well as Kenneth Tan who earned $171,800 in 2011 and $376,224 in 2012. Garry Dawson, VP technical services, suffering under current austerity, had only a 20% raise between 2010 and 2012.
