Gosh, and this being the first ever cable-stayed bridge there was no knowledge that there might be a problem like this. 
Every other cable-stayed bridge in a temperate climate has suffered with this to some extent, yet the government have managed to remain ignorant of it until last winter, then managed to do f

And every other cable-stayed bridge has the same solution in similar conditions - shut the bridge until the danger has passed.Every other cable-stayed bridge in a temperate climate has suffered with this to some extent, yet the government have managed to remain ignorant of it until last winter, then managed to do f

We've had such an array of 5* talent in the position of Transport Secretary in the last few years, how can such a thing have happened? And with it shut again this morning people are experiencing the joys of 3 hours to do Fife to Edinburgh. Add to that flooding on the road from the M90 to Kincardine and it's just a total clusterfk.
I'll be correct in assuming that the square root of fk all has been done to address the icing issue since last winter then? It's not as if cold weather at this time of year is an uncommon event.
Awaiting 'burger to pop up and tell me I must be wrong as he just managed Dunfermline to Queen Street in 15 minutes...
and jeez indeed.

It might not flow as fast, but at least folks could get across. I know it would be a capacity reduction as it's only got 2 lanes...oh, wait

It's shut. Roadworks starting yesterday - http://trafficscotland.org/currentincidents/detail...It might not flow as fast, but at least folks could get across. I know it would be a capacity reduction as it's only got 2 lanes...oh, wait
It looks like I got lucky this morning, finished my Nightshift in Livingston at 3.30am and got back over the bridge at about 4. Glad I didn't have to stay on as the extra 50 miles or whatever really wouldn't have been appealing!
On the plus side, the upward facing lights on the bridge made it look pretty impressive with the sideways snow

.the best i can find,
They detected a phenomenon known as “ice accretion” in which it accumulates on the crossing like a crust in very specific weather conditions.
But rather than build up over a long period, the sheets of ice falls soon afterwards, sometimes in large enough pieces to smash vehicle windscreens, as happened on the bridge last year.
So the sensors when trigger - close the bridge.

I read that article earlier too. It’d obviously disappointing the QC was closed for four hours yesterday, but that seems a sensible reason. They detected a phenomenon known as “ice accretion” in which it accumulates on the crossing like a crust in very specific weather conditions.

Or maybe it's just The Herald trying to put an anti-SNP slant on things, what are the odds?

I thought last year when it shut it was "unusual" or "very specific" weather conditions? Is it going to shut each time there is snow in a slightly different way to the very specific snow it was designed to deal with?! One wonders how the Nordic country's transport systems work if their bridges shut when it snows.

Looks like today is another very specific day 
If the bloody thing is going to close this often they need to be opening the FRB to all traffic. Ridiculous.emicen said:

So what was problematic about today's weather which was out of it's design envelope? If it's going to shut 50% of the time it snows in Scotland then it's going to spend most of winter closed. Unbelievable that this is considered acceptable, either by SNP's, the local council, or the company who designed it. More incompetence from Holyrood.
Why can they not put heating elements on the parts which are problematic? It only has to be kept at 5 degrees or so to prevent the ice settling, one would have thought. Works for other structures and installations.

That can be done but it would appear they've decided it would be too expensive. It would have been a lot cheaper to do before installing the cables.Why can they not put heating elements on the parts which are problematic?
