    Will this be HQDC? Any idea when works will commence?

    Mention of a motorway order on http://www.n28cork-ringaskiddy.com/ seems to imply it will be M.

    The Bloomfield interchange already being free flow is a great start for this project. Hopefully it will be M and it will one day tie into a motorway upgraded N40.

    It's time to put motorway restrictions on the N40. Absolutely no reason as it is not to.

    Expect the N22 to be upgraded too once the Ovens to Macroom section is complete.

    Hopefully over the next few years a road reclassification plan is drawn up and someone sensible is put in charge. The N40 should have motorway regulations regardless of the lack of hard shoulders on the Douglas flyover. The Estuary bridge on the M1 has no hard shoulders ever since it was widened to D3M. There are no longer any at grade junctions to contend with either.

    A lot of upgrading to be done means some roads should be downgraded too (eg. N83, N84, N87) but that's for another thread.

    Didn't realise they were planning an M route here, will be Irelands shortest motorway by quite some measure.

    http://www.cisireland.com/project?id=831831&title=m28-cork-to-ringaskiddy-motorway-scheme

    Also specifically mentions "M28 Cork to Ringaskiddy Motorway Scheme" on that page.


  • Registered Users, Registered Users 2 Posts: 4,561 ✭✭✭AugustusMinimus


    Could well be a stipulation of the EU funding.

    With this scheme and the Dunkettle Interchange being done, the whole N40 should be designated.

    In my mind, local access and at grade junctions are the only thing that hold back motorway designations. Lack of a hard shoulder in small patches should not.


  • Registered Users, Registered Users 2 Posts: 5,541 ✭✭✭Leonard Hofstadter


    I assume the motorway would only be to Carrigaline? Have we any idea how much of this actual route is going to progress, will they just go to Carrigaline or will they go all the way down to Ringaskiddy? To my mind they really need to do the whole thing, they really ought to after Cork losing out with the M20.

    AFAIK, it is going all the way to Ringaskiddy as it is specific port funding from EU that is paying for this new road.

    Pretty sure it's mway to Carrigaline then 2+2 beyond.


  • Registered Users, Registered Users 2 Posts: 5,541 ✭✭✭Leonard Hofstadter


    Thanks. I'd say that will have enough capacity. Clearly a single carriageway would not be appropriate beyond Carrigaline, but HDQC/motorway is probably a bit overkill. I just hope when the tenders etc they will do the entire thing not just to Carrigaline as was suggested by sponge bob on Skyscrapercity.

    Doing it to the Shannonpark roundabout would just move the present N28 issues bulk up beyond the roundabout and have a jam through Shanbally and back onto the M28 every morning.

    The entire length of the N28 at present is 11km, and also is getting subsidised by the EU. If doing a 11km scheme is such a major struggle then we may as well give up on trying for the 80km M20


  • Registered Users, Registered Users 2 Posts: 5,541 ✭✭✭Leonard Hofstadter


    True, Shannonpark to the N40 interchange really isn't that far at all (not that you'd notice most of the time due to the chronic traffic congestion this road suffers from, mind). It's just when Sponge Bob mentioned about them getting EU funding no matter how much of it was being done is what has got me worried. Of course even going that far is better than nothing, but really it should of course be a proper job and bypass Shanbally etc.

    From what I've heard the original plan was motorway/dual-carriageway all the way, but since they had to change the route of the last stretch from Shanbally into Ringaskiddy because of environmental concerns about the original route closer to Loughbeg, that the last bit connected to the port will be HQ single-carriageway due to space restrictions. IMO this shouldn't be too much of a problem. Working in Ringaskiddy, I very rarely have problems with the last bit, it's once you pass the pharma plants etc. that the traffic builds.
    The new final route hasn't been decided yet though so that could all change.

  • Registered Users, Registered Users 2 Posts: 4,561 ✭✭✭AugustusMinimus


    Absolutely fantastic news. This is something I predicted / wanted all along. I've raised this issue with a number of local councillors. Not sure if it was me saying it to them or the plan all along but I feel a bit proud today that the junction is being altered just as I asked for.

    http://www.boards.ie/vbulletin/showthread.php?p=93992614

    This new road in conjunction with the bridge over the Moneygurney river (shown in red below) will create an alternative route south of the South Ring Road. The likes of Moneygurney and Donnybrook will now have very easy access to the M28 compared to now where the situation is a nightmare.

    Glad to see they have gone for this solution. A little drawing I concocted.

    And here is the official new junction.

    I'm curious about the tie-in with the Bloomfield junction at the northern end. I highlighted the bit I'm on about in this image :
    366308.png

    Are they proposing to build an additional fly-over over the Rochestown Road? It looks like they are, and that it would be to the west of the existing on-ramp here.


  • Registered Users, Registered Users 2 Posts: 3,985 ✭✭✭mikeym


    Its a good idea to close the slipway from Maryboro Hill onto the N28.

    Although the locals mightnt be happy.

    It causes a bottleneck.

    Yes it looks like it will be a dedicated two lane slip road for M28 northbound to N40 westbound. The northbound merge from the Rochestown road up to the interchange looks like it will only allow a N40 westbound movement? Graphics in the leaflet are very poor, they should also publish drawings showing the layout from Carr's hill to Bloomfield, its hard to get an overall picture from the snapshots of the junctions they have provided.

    The Rochestown slip North bound will still be the same. It will just merge with the new carriageway going westbound. All movements will still be catered for.

    An interesting solution which I wasn't expecting.

    Douglas flyover is going to be chaos. I really hope they are working on plans to widen it to 3 lanes in each direction.


  • Registered Users, Registered Users 2 Posts: 4,561 ✭✭✭AugustusMinimus


    Actually, after viewing on google maps, the additional carriageway will have to result in the CPO of upwards of 40 houses from various Douglas housing estates. The picture below doesn't even take in most of them. Very interested to see if this will go ahead.

    This additional carriageway will definitely result in the closure of the Maryborough on slip.

    This is going to cause a lot of disruption.

    I thought the original plan was to bypass Carrs Hill, Shanbally and Ringaskiddy.

    I don't think it will be as drastic as knocking 40 houses. There's room enough to build a retaining wall against the bottom of those gardens and squeeze the extra two lanes in. It'll be tight, but it is doable.


  • Registered Users, Registered Users 2 Posts: 5,541 ✭✭✭Leonard Hofstadter


    Interesting set of proposals. I can see why they want to remove access to the N28 from just beyond Broadale, will be a bit of a pain for anyone living there but it has to be done really. If this goes ahead I can see it providing some relief to traffic infested Douglas as fewer journeys should require going through there (theoretically at least).

    Anyone got any idea when this will all kick off? I'm assuming not for another 2-3 years as a bare minimum anyway. If it's an EU requirement for it to be motorway as part of the TEN-T funding does this mean the motorway will in fact go all the way down to Ringaskiddy?

    Does anyone know, is the existing bridge on Maryborough Hill over the N28 going to be wide enough for the M28 under it or will it have to be demolished and rebuilt?

    I reckon you could fit two lanes each way without any hard shoulder but probably not motorway standard. Maybe there's some way they could adapt it?

    The split is where you exit to head to Carrigaline or merge towards the city coming from Carrigaline

    A lot of residents getting very angry about the potential closure of Maryborough slip.

    I don't think they fully understand what's happening though and how potentially there may not be any space even for the slip.

    But there's another junction indicated almost at Carrigaline, pretty much where the existing Roundabout is.


  • Registered Users, Registered Users 2 Posts: 315 ✭✭moyners

    My reading of it is the roundabout is staying with the motorway passing over on a flyover. The flyover is what's marked i think.


  • Registered Users, Registered Users 2 Posts: 8,779 ✭✭✭Carawaystick


    I wonder is it an access only junction towards Cork from Carrigaline, with exit to Carrigaline at the northern exit?


    Anyway, the entire rational for this having to be a motorway seems odd, when the last section before the port has a footpath drawn in on its cross section.

    (posted by Augustusminimus earlier in the thread)

    There was a closer view in the original plan (i don't think this section has changed apart from going through the quarry instead of around)

    The very last section won't be motorway but will pretty much enter the port complex from the western side. I think it will be fine as most of the non-port traffic will have filtered off by that point. They wouldn't have the space to fully dual it at the final section but it really is a very short segment of the whole thing.

    Maryborough Hill residents not happy with proposed slip closure.

    http://www.eveningecho.ie/cork-news/closing-slip-roads-would-be-lunacy/1171517/
    REMOVING slip roads off planned M28 road to Ringaskiddy could add up to an hour on the daily commute of residents in theMaryborough and Mount Oval areas, a meeting was told last night.

    More than 100 people packed the Garryduff Sports Centre to discuss plans for the proposed motorway, which will close off important sliproads from Maryborough and Mount Oval.

    Residents and politicians said they felt the Port of Cork was put before the public in the planning of the new road.

    I don't think they realise that a 400m drive up the road to Maryborough Ridge will get them onto the M28. That and the fact that unlike now, they will also be able to come off the M28 at this junction too.

    The claim that the change would add an hour each way onto a Marborough resident's daily commute is one of the most ridiculous things I've ever read. Due to various issues with junction design at Bloomfield and issues with weaving, using Carr's Hill under the new setup will most likely be quicker than using the Maryborough slip now which has traffic constantly backed up in the mornings.

    Ridiculous doesn't even begin to describe it. Can't see why anyone in the area would object to any of the plans as the benefits the M28 brings far outweighs the cons of closing that slip

    Like when the N21 Adare-Abbeyfeale scheme was proposed and vehemently objected to as apparently the entire economy of West Limerick is based upon the sale of soft drinks, coffee, petrol and sandwiches to passers by, yet the same locals don't see the benefits of being able to actually move around their towns/villages in the evenings.

    Yeah, as the failure to build the road affects everyone trying to get from Kerry to Limerick/Dublin I wonder would a call to boycott all those shops and petrol stations along the section knock some sense into the local business community? :D

    Slogan could be "You are taking half an hour longer to get home because 20 shops owners want to force you to stop".

    Though I'm sure a PR person could make it snappier....

    Google is calculating it as 12.7km https://www.google.ie/maps/dir/51.8313429,-8.3090851/51.8798852,-8.4205863/@51.8693861,-8.4210105,12z/data=!4m2!4m1!3e0

    However, comparing a ring road with more than a million people within 5km with a port access route with a few ships per day at the end of it is hardly meaningful. A big part of the N28 is to provide a commuter route.


  • Registered Users, Registered Users 2 Posts: 4,561 ✭✭✭AugustusMinimus


    There are only 8 junctions on the route.

    The 2nd and 3rd dots refer to junctions which are being closed. You've also counted 2 dots where there is only one junction.

    In addition, the last 2 dots are junctions where the road will Ni longer be motorway.

    You wrote "11 junctions in 13km? Hmm, yes, strategic motorway."

    AKA, how can a strategic motorway have so many junctions in a short distance.

    My counter-point was that the M50 is definitely a strategic motorway, yet has many junctions in a relatively short distance also.

    If you want to change your argument to "nowhere outside of intercity needs to be motorway status" fine, but that's not the point you made.

    I'm not sure how my Google maps managed to map it wrongly for me, my apologies on that one. Perhaps it did something to avoid traffic (15.00 on a Friday).
