    Judging by the progress on the pictures I think it's fair to say this should open by the end of 2017 if not sooner. Although it's quite a big scheme 56km is a lot of motorway.

    Don't think it's piling, it's stucking the bog water out, the stoned bog area will then be left to settle for 12months before anymore fill

    You may be right, I heard that the bog must be let settle for a period before anymore work

    Ya, its called sur-charging, its common enough on soft ground, prevents the road/final surface from settling when the traffic goes on it. If its very soft they might still pile a section of it.

    Does anyone else think that the projected finish date is a bit generous? 3 years in total.

    Galway - Ballinasloe took 2 years. Same distance plus a crossing of the suck and toll booths etc to get done - and the surface is the finest in the country IMO.

    Well just up thread there is a discussion about making good bog ground, that takes a long time, so with that in mind I'm guessing the timescale is reasonable.

    When they built the Limerick Neenagh section of the M7 they went through two section of bog which they were warned by locals to stay out of. A few months before it was meant to open an entire section of the nearly complete motorway broke off, I kid you not http://www.irishtimes.com/news/part-of-motorway-which-sank-into-bog-to-open-in-october-1.644674

    Took them a very long time and a lot of expense to fix it in the end.

    There is a great thread here on boards about it and a lot of great pictures. They ended up digging up a few KM of the motorway and sinking huge piles and then laying a concrete cap before they could rebuild the motorway on top

    Do not underestimate bogs!

    Do not underestimate bogs!

    I worked on that job so let me explain what actually happened. When the initial site investigation was being carried out the company carrying out the survey found the depth of solid material to be approx 9 to 11 metres deep. they came to a section of bog which was very soft at Drominboy so they decided to come at it from the other side. Again the depth came in around the 9 to 11 metres to hit solid material until it got too soft to continue. They assumed it was the same all the way through to where they stopped previously coming from the other direction. Assumption being the mother of all fcuk ups, the bog ended up being bowl shaped with depths of over 20 metres being recorded when piling.The piles that they made on site were to slim/slender and when the piles were driven in the soft area they basically buckled under the weight of the new road and so start to sink. So a massive concrete slab was poured over the whole area to spread the load of the road hence the photos on the other thread.
    When they were making the haul road, 18 Volvo A40 dumptrucks hauled rock solid for a day and made 20 metre long of a road, all the bog was pushed up either side knocking over trees and making a wall of bog both sides!!
    Bogs indeed cannot be trusted!

    Thers no pile driving, what they are doing is vertical drainage to varying debths 9.5 metres currently, when this is complete two layers of rock will be placed and then it will be allowed to settle for some months, movement will be monitored and based on this the next stage will progress.

    Only if the condition after the surcharging is bad enough they them MIGHT pile, usually the settlement is enough to squeeze out the water and consolidate the ground underneath making it suitable for pavement construction.

    I may be missing something but it's not clear to me why speed restrictions are necessary on the M6 at present. Construction work so far is outside the M6 boundary fences (I think). Obviously, as construction of the interchange progresses, work will move inside the boundary - speed (and maybe lane) restrictions will be needed then.

    Can anyone shed any light on why the speed restrictions are in place now?

    Is there site access/egress from the motorway now? If so a speed restriction would be needed.

    Its safer to rubberneck at 60 km p h than at motorway speeds.

    They can't just slap up speed restrictions whenever they like: they have to go through a formal process.

    So to keep it simple for themselves, they always just slap a restriction on the entire stretch for the whole duration.

    At one stage they were redoing the Athlone bypass in short stretches, first one side, then the other, but they hit the entire bypass both ways with one speed restriction order, because it is simpler for them than doing 16 different ones which would apply to each stretch in turn.

    Absolutely. How am I meant to balance my phone on top of the steering wheel whilst gripping my coffee between my legs to take photos if I am doing 160Km/h. 60 Km/h is much more camera friendly.

    And talking of which:-

    Rathmorissey junction starting to take a bit of shape now with supports appearing on the eastbound carriageway. Also on Westbound I see a lot of scaffolding went up on one of the support sections.

    Am I right in saying this will be the first 3 Tier junction in the country ?

    M50/N3 has at least three tiers, and more if you count the canal/railway layer that passes through it.

    Its like a large roundabout going around the mainline carriageway, that why there are 3 sets of bridge abutments.

    Two for the roundabout, the middle bridge is the M17/18 mainline going over the top.

    Will the N63 between the current N17 and the new M17 be detrunked to an R road? Or will the current N17 from the N17/N63 junction to Galway be redesignated the N63?

    The most visible progress can be seen at Rathmorrisey on the M6, where the upright structures for new bridges over the existing motorway have been installed.

    The bridge beams for all three bridges will be placed over ten nights beginning on the 23rd of November.

    The project team says there will be some disruption to traffic on the M6 during this period, and diversions will be put in place.
