Vancouver Off-Topic / Current EventsThe off-topic forum for Vancouver, funnies, non-auto centered discussions, WORK SAFE. While the rules are more relaxed here, there are still rules. Please refer to sticky thread in this forum.
I'm not a bridge engineer, and I'm assuming you're not either, so it would be presumptuous to refer to the bridge design as flawed. It doesn't take an engineering degree to recognize the decision to extend the cables above the deck was made after cost-benefit analysis, and the design may offer much improved safety during an earthquake or some other incident this audience simply does not have the education to be aware of.
The Leonard P. Zakim Bunker Hill Memorial Bridge in Boston.
Boston is prone to severe snow and ice storms, but the only stories on snow and ice falling from cables causing damage are related to a 2005 storm. That should support the explanation of this incident being caused by an extremely unlikely series of events, not considered worthwhile by the government or public to pre-plan for the possibility of occurring. The deck of this bridge also appears to be very wide, and since the new Port Mann is the widest cable stay bridge in the world, it stands to reason that the layout of cables may be required with an increase in size on that axis.
I agree, it's too early to say whether or not it's an actual design flaw or rare occurrence.
A background in engineering would provide a solid foundation in analyzing the historical weather data between that Boston bridge and this Port mann one. Some variables I can imagine are:
angles of the cables
coating
heat traced - is the Boston bridge heat traced or have some sort of preventative measure for this already?
environmental factors - humidity, how often does the temperature hover between -2/+2? If Boston's winters are colder than Vancouvers, then maybe these two bridges aren't comparable. Perhaps ice melts slower in Boston than Vancouver due to slower temperature changes. Rapid temp changes could attribute to falling ice
people just aren't calling the DoT enough to complain the DOT asks for people to call them when there's problems so they can post a warning on signs near the bridge
Could any possibility of this type of situation ever occurring been eschewed by a design that more thoroughly accounts for very rare circumstances? Yes, but seriously overbuilding would simply provoke outrage from the public for wasteful spending and exorbitant tolls.
And of course, we all know what would happen then: some bored reporter or hacktivist would be poking through the bridge contract and see that there was a massive amount allocated for heated cables or whatever sort of ice mitigation strategy... the cost would be made public... and there would be such a hue and cry because, of course, IT NEVER SNOWS IN VANCOUVER! IF THEY HADN'T SPENT ALL THAT EXTRA MONEY ON THOSE HEATED CABLES, THE TOLLS COULD HAVE BEEN 10 CENTS CHEAPER! WHAT A BUNCH OF IDIOTS!

It's not a logical oversight or an engineering problem. It's a well-established fact that LRT systems are susceptible to snow and ice, but ideal solutions break the bank, and transit projects don't have unlimited funding, so the engineers settle on a system that is great 350 days of the year, and less than ideal the other 15 days. It's no different than roads or airports, people who travel by means of those corridors experience the same delays due to snow and ice.
Yep... we saw the same thing a few years ago when we got all those dumps of snow, and the cities (Vancouver in particular) were being berated for not having enough snow-clearing equipment to keep up with it all. "Of course it snows in Vancouver, how could they not know this and not have three times as many snowplows?!" And of course, when the city managers try to explain that it's just not cost effective to keep that many trucks sitting idle for four or five years just so they're there when the sixth-year blizzard comes, well, they're just talking out their asses, aren't they?
And naturally, if they DID have the extra capacity to deal with the odd MASSIVE snowfall, you'd see news reports every winter in between about the Snowplow Graveyard, where all these trucks (aka your tax dollars) sit idle, year after year - a classic example of bureaucratic overspending.
Fucking armchair quarterbacks.

Extreme weather? It was just a little snow...not even a whole lot. What happens when it snows again next week? Or next month? Or next year? Yes, we'll keep blaming it on the weather.
Sounds like bureaucratic bullshit to me.
What happens? Probably nothing.
Extreme weather? Maybe a poor choice of words. Extremely rare combination of factors. Yes, we'll get snow again... but not the exact conditions that would lead to it sticking, then forming ice, then breaking off and dropping straight down, rather than sliding down the cables.

I finally found the limits of my stock height 01 QX4 in 4x4 mode with Nokian snow flake rated all-weather tires.
There was over a ft of snow plus the snow being pushed up from the plows. I sorta got my truck stuck trying to park in my usual spot. After 10 minutes of rocking the truck I was able to get her unstuck.
Woohoo.

How many drivers use the bridge each day? 3 reported incidents in 9 years? Sounds like they're trying to make a mountain out of a mole hill.
It would absolutely suck if you happened to be one of those 3 drivers caught by ice. But, your odds of getting seriously injured by a drunk dirver or some stoned guy in a Range Rover are much higher. In fact, every time you get in your car, you are putting your life at risk. Posted via RS Mobile
heard on global that the mayor has a few dedicated trucks to clear bike lanes instead of major roads
On that topic

More bike lanes were cleared than major routes: councillor
George Affleck questions priorities
VANCOUVER (NEWS1130) – While many major routes were impassable for drivers during yesterday’s snow storm, Vancouver bike lanes seemed to be bare and clear.
One city councillor admits he is frustrated by what was considered a priority during the madness. George Affleck is now calling for a report to be completed in January to pinpoint what happened.
“I saw a lot of craziness on Broadway yesterday with buses… and I saw a snow plow go by on Ontario [Street] to clear a bike lane,” he tells us, saying that’s totally unacceptable.
“When I see the kind of weather we had yesterday and I see buses skidding with many commuters and many people on it… and I see snow plows going down bike lanes, yeah it concerns me.”
Affleck also points out that many businesses did not keep their sidewalks clear, thinking the rain would wash away the ice, which it didn’t; many people slipped their way up and down hills, at times with the help of total strangers.
“I didn’t see Broadway cleared until about 5 p.m. yesterday,” he says.

like i said it happens far more often to the point that people i know avoid it during winter storms
obviously the damage it causes may not be severe or else i imagine the DOT would get far more reports; but they're not the police/insurance either, how many people do you know contact translink directly when they get in an accident?
however as said we'll have to see how often this happens for us since our weather is drastically different
Transporation Investment Corporation is waving the toll for anyone who drove the Port Mann between 10am and 6pm yesterday, and it will pay the deductable for the damaged vehicles
my friend drove his Lexus into a small ditch yesterday because of the snow haha
I see more 4x4s in ditches than I do any other type of car. Overconfidence. People who are really afraid to drive in the snow stay home. People who are cautious get stuck or slowly get to where they're going.
I remember back in the good ol' BCDSM days there were a couple of guys who went up to Cypress with chains and tow cables to pull out the stuck 4x4s.

), he actually seems pretty well rounded:
good thing it was there when I bought the car and its a cheap lip anyway
