    "well paddy, like we've feared all along, i do wonder when they'll elect to traffic manage the approach to both bridges based on 'current congestion conditions'"

    Wouldn't this involve huge amounts of infrastructure changes to enable in any sensible way? There's not the capacity on the slip roads to the old bridge and I think diversions could only work on an "all or nothing" basis.

    "The disruption is expected to cause delays of up to four minutes during the morning and evening peaks."

    The poor things. How WILL they cope?

    aye jonty, on sober reflection that sounds about right

    So, I went over the QC and back on the FRB last night.

    It was late so no traffic but did make me wonder if the ability to run traffic over the FRB is going to be a permanent feature of if they will be digging up the tarmac & crash barriers so you can only access via the bus lanes.

    Anyone able to point me to final layout?

    @hankchief, not sure where the final layout might be Nor if it will be the final layout. I would put money on it being left open to cars though.except when fpvery windy when cars will have to use the new bridge :-)

    Are there examples from elsewhere apart from the Forth? I think cars go over both Kincardine bridges but might be wrong but would be good to be aware of double bridge scenarios side by side where one of the bridges is car free? Cars seem to be able to get everywhere.

    The Forth Road Bridge remains closed this morning due to high winds with the Queensferry Crossing open in both directions.

    The decision has been taken due to the weather forecast in the coming days.

    With high winds expected it would result in peak time restrictions on the diversion route over the Forth Road Bridge.

    It was thought that the Forth Road Bridge diversion would be in place this morning, but it has been unable to open due to winds.

    But it’s not particularly windy.

    agreed @chdot - i crossed it this morning !

    i suspect some other reason ;-)

    I guess it's the forecast high winds which have caused this. They don't want the egg on their face of having to ban southbound traffic on the FRB while there are holes in the tarmac on the QC. They therefore can't dig up the tarmac while there is a wind warning in place for the coming days. If they aren't digging up the tarmac there is no other reason to keep traffic off the QC so they have reopened it.

    It seems to make sense when you think of it like that.

    the bbc page quotes Yousaf as saying

    "Since the initial study in 2007 the objective of this project has been to provide a replacement for the Forth Road Bridge.

    "As such the Queensferry Crossing does not increase capacity over the Forth and we still expect congestion at peak times.

    so who designs and builds a massivley expensive bridge starting 10 years ago without any additional capacity at that time , as well as now 10 years later.
    wouldnt the logical thing to have been add a few more extra million quid and make it a 3 laner to INCREASE capacity? its not like you can just build bridges willy nilly.
    incredulous!

    Not really - because then you have wasted X tens of millions to move a bottleneck around. It would have plenty of capacity if the number of people crossing the Forth was anywhere close to the number of seats crossing it.

    People who think that increasing the capacity would result in bigger congestion problems somewhere else?

    They've changed from a bike lane about 2m wide to a bike lane over 3m wide for most of the good bit. That's an astonishing amount of extra capacity. I suspect far more than a full lane of typically occupied cars.

    Too bad the media wouldn't take a press release stating actual numbers seriously.

    TRANSPORT bosses are ready to take extra measures to improve traffic flow on the approaches to the Queensferry Crossing if the increased 70mph speed limit fails to sort out congestion.

    Arf! Yeah, magic line painting is the answer to everything, it seems.

    “They recognise the Queensferry junction just before the bridge is causing tailbacks at the A904. They want to see what happens with the speed limit at 70mph, which might ease the pressure on that roundabout. But if it continues, they are willing to consider a box junction, where the road is marked with a yellow grid which motorists can enter only if the exit is clear.”

    Aye, if only we can add a bit more capacity we can solve it.

    Will they ever learn?

    Faster speeds = lower road capacity?
    Can't understand why they would want to 'encourage' 70mph as I think people's attention will still be distracted with new bridge crossing. / road layouts. Any increase in accidents would remove any advantage - if there are any.

    I know they will think it's good PR of course but if they then have to reduce it then expect a backlash from pro-car media.
    Public transport hasn't really benefitted and that is really the key to improving flow amongst those that 'need to drive'.

    I thought the real solution was going to be metering, where only a limited number of cars could enter via the slip road every minute, thus reducing the bottleneck effect at the start of the bridge. It might also have the effect of disincentivising 'queue jumping' by taking the inside lane up to the Queensferry roundabout and then going straight back onto the bridge.

    Top bantz there Alex - next you will be telling us that cars can't park on yellow lines.

    Mrs Garto giving spirited defence of drivers tonight, along lines of most obey the rules. We had just been undertaken by man driving Mercedes estate in the bus lane at The Gyle at the exact time this is verboten. Once over the bypass roundabout we were then undertaken again by young lad driving in the bus lane, there were no further bus lane from the park and ride at Heriot watt onwards to Balerno for any more undertakers.

    Yesterday's experience of driving over the new bridge from Fife (tailback from junction
    2) suggested that the problem is entirely caused by p*sspoor driving.

    Essentially, you're in nose-to-tail crawl up to the start of the bridge, then as you rise up to the apex of the bridge everyone accelerates away to 60mph. So it's caused by poor filtering from the junctions, especially the Ferrytoll one, followed by those new joiners crossing the lanes of traffic to get to the outside lane, thereby slowing both lanes.

    It really is time that Transport Scotland responded to the bridge-congestion complaints by saying "The design is fine, it's drivers' fault. If people learnt how to drive considerately and cooperatively, they would all get home 10 minutes sooner."

    That's how it always was on the old bridge too - fast from the peak of the bridge. How much of it is bad driving and how much is simply an inevitable consequence of lots of cars merging onto a road which is full already?

    Meanwhile our Local MSP is trying to get the old slip road from Echline onto the city bound A90 opened because, y'know cars...

    "The B924 through Dalmeny to join the A90 this morning. This is the impact of both the closure of the A90 slip at SQ due to #QueensferryCrossing road layout and the absence of the Burnshot Flyover. This is unsustainable, @TransportScot, @HumzaYousaf- please re-open the A90 slip"

    I may have taken him to task...
