N22 - Macroom to Ballyvourney (Macroom Bypass) [under construction]



  • Moderators, Entertainment Moderators, Science, Health & Environment Moderators Posts: 13,229 Mod ✭✭✭✭ marno21

    Confirmed in de paper yesterday also that the Council are in discussions with the contractors about an early opening later this year.

    is the plan to open the bypass as far the Millstreet road, or further west (Carrigphuca)?

  • Registered Users Posts: 4,964 ✭✭✭ Chris_5339762

    No-one is sure yet. Opening to the Millstreet road would free up the centre of Macroom but it would be messy getting back to the current N22. Opening to Carrigphuca is tricky as there is no junction there. I still feel that is more likely though - some form of temporary terminus I'm sure would be possible there, and would get Macroom done and dusted anyway.

    Purely speculation on my part but the fact that they’re in discussions with the contractor would suggest to me they’re looking at Carrigaphooca. Opening as far as Millstreet Road would be a simple job as soon as the contractor have handed over that section

    "My guess is that it’ll open with one lane each way, with two rows of cones down the middle to reserve a through-way for construction traffic."

    We don't do this that much (at all?) in the South, but up North, they do it regularly - it was done around Castledawson on the A6 during the recent construction, and further along the A6, it is currently being done on the Dungiven->Derry section.

    I was thinking that - at about 5:58 you can see the barriers across the new road - I reckon they could do a wide sweeping hairpin onto the temporary construction ramp and down onto the old road at a T junction of sorts. It's do-able I think, but I wouldn't be an expert on it. The gradient is no worse than what they have temporarily on the M8 at Dunkettle.

    Going to Millstreet Road.... thats fine too as long as people realise it would be for the benefit of Macroom itself, and not to save time for drivers. The route back to the N22 plus the new road would be about the same off peak as ploughing through Macroom itself.

    It’s worse than it looks. The drone camera is compressing the difference in heights. If you’ve driven near there it’s a pretty steep incline from the re-routed old road up to the new mainline. They’re not doing temporary tie-ins at Dunkettle because they think it’s good, but because have no choice. Also, that’s a 60 km/h limit, with traffic lights and enough traffic movements in place to keep the real speed close to that. On this scheme there is an alternative to a temporary tie-in, and that temporary tie-in wouldn’t be on a controlled junction, but in a remote area with a high chance of people driving far above the posted speed.

    If they did do a tie-in, I fully expect it would result in some fool driving their car through a barrier late one winter evening, and then the cost of the inevitable court-case against the council and the contractors will delay the project, and guarantee there will never be another partial opening of anything, ever.

  • Registered Users Posts: 4,964 ✭✭✭ Chris_5339762 I almost did on the Banbridge bypass! They were doing roadworks late one night, and it was a very poorly signposted diversion where you did a hairpin turn and went up the onramp, if that makes sense. Absolutely terrifying.

    I hope they do go to Carrigphooca and just work out a way somehow!

    The N30/N25 New Ross Bypass is another fairly new road that has no hard shoulder for most of its length. Only the slightly busier section on either side of the bridge at the western end of the route is HQDC - the remainder is 2+2. I’ve travelled it many times and it is a perfectly safe design for the relatively low traffic volume.

    Any updates on progress ?

  • Registered Users Posts: 131 ✭✭ Ambush Rebel 2010

    Roundabout at Coolcower is 90% complete and I would expect it to be fully functioning shortly.

    As for the Macroom section of the bypass, It looks like surface is almost ready with tidy ups to do.

    Works on the dividing barrier has started but early stages as well as lining yet to commence.

    Has it been confirmed what will happen on the western end? Will traffic be brought back onto the existing route via Millstreet cross or will a temporary solution be put in at Carrigaphooca?

    Thats still the golden question. No information on where a temporary tie in will be.

    Any mutterings coming out about a partial finish or indeed a date for a full finish (well open to traffic - tidy up works)

  • Registered Users Posts: 19 kegblag

    I heard several weeks ago the rumoured target was October bank holiday weekend for a partial opening. If I'm the only person who's heard that rumour I'd not take too much notice of it though.

  • Moderators, Entertainment Moderators, Science, Health & Environment Moderators Posts: 13,229 Mod ✭✭✭✭ marno21

    You aren’t - that rumour has been going around a while now. Any further works complete along Coolcower-Gurteenroe?

  • Registered Users Posts: 546 ✭✭✭ KrisW1001

    Full finish is still down as late next year - I’d guess October/November 2023. That date may slip due to the partial opening of the eastern end.

    I had a look at this on open street map and would work ok.

    Local traffic the town side of the potential tie in at Carrigaphuca could get to Macroom via the old road and anyone to the Kerry side of the tie in could get to Macroom on the new road via the Millstreet interchange.

    There'd be an odd house or potential routing that might have a longer way for the duration of the tie in being in operation but it wouldnt be drastically longer, and not enough of an inconvience to put off relieving 1000s of residents and motorists from the pain of a congested Macroom.

  • Registered Users Posts: 546 ✭✭✭ KrisW1001

    You haven’t considered local traffic that is not going to Macroom at all, and will continue to use the current N22. For these users, the new roundabout and link roads must remain open as they are now, and it is this that makes a tie-in so dangerous here:

    Local traffic from west of Macroom (the blue line) is in direct conflict with Killarney-origin traffic (green line) wishing to join the new road. The distance between the crossover point and the roundabout is barely 150 metres, and traffic that has just turned left off that roundabout will be naturally be accelerating, as will the right-turners joining the new road.

    If you were designing a layout to encourage high-speed frontal collisions, this would be a good starting point. And to save less than two and a half minutes of travelling time bypassing a free-moving road at a lower speed limit with one at a higher limit?

    And as for relieving Macroom, opening from Coolcower to the Millstreet Road will do this already. The western edge of Macroom town does not suffer from traffic congestion except as a result of eastbound traffic backing up.

  • Registered Users Posts: 4,304 ✭✭✭ serfboard

    Would a temporary roundabout not solve this problem? If there is to be a partial opening, anything other than Carrigaphooca is sub-optimal, IMO.

  • Registered Users Posts: 546 ✭✭✭ KrisW1001

    There isn’t room for a temporary roundabout on the new link road, and one could not be built on the dual carriagway. Maps are flat, and that’s fooling a lot of people, but the terrain here is not: at their closest point, there’s a considerable difference in height between the new and old roads (around 3 metres, I think), and that makes any tie-in more dangerous and expensive.

    I don’t get why the partial opening as far as Millstreet Road is now seen as a poor option - it means that for the first time in decades, Macroom town centre will not be choked by traffic. To me, that is a major win.

    All other problems on either side of Macroom are due to that congestion within the town centre. If I’ve been stuck in traffic before the Auld Triangle (west of the Millstreet Rd), that traffic jam has lasted all the way through Macroom to Coolcower. Once you fix the centre, there’s really no need for a longer-distance opening, because traffic will be running freely on the old N22 between Millstreet Rd and Carrigaphuca.

    And 18 months from now, the whole thing will open, and whether or not a a tie-in was built won’t matter - it seems like a lot of effort, cost and risk to go to for such a small benefit for such a short length of time.

    Michael Creed is saying on his latest Facebook post that the bypass between Coolcour and Carrigapooka will open before the end of the year so that confirms that it wont be just as far as the Millstreet junction.
