    I get the impression than a lot of people have no knowledge of Little Islands western entrance.

    Is that the one at the tunnel mouth?

    I have heard that some traffic is now carrying on to the Fota/Cobh Junction slip road, returning from the East to access Little Island in the mornings "because it's faster than queuing the normal way or using the magic lane".
    The magic lane, of course, being the western entrance to Little Island.

    Basically, people find it's difficult to use the Western Entrance to Little Island because the volume of traffic clogs up the interchange. Traffic trying to cross lanes is impeded, rendering this entrance to Little Island less usable.

    They should probably do a third entrance involving a new bridge but only accessible from the old road through Glounthaune.

    A slip entrance at the very east of Little Island when travelling west would be quite easy to do too.

    South ring eastbound towards the tunnel from 5pm onwards has become atrocious the last 2 weeks.
    Traffic backing up to Douglas.

    This interchange badly needs to be fixed.

    Have seen it back up as far as the on ramp at Kinsale Road sometimes. Douglas flyover narrowing to 2 lanes doesn't help either. This and M28 are crucial for Cork and are needed now.

    This was posted in the flyover thread 5 years ago.

    I've emailed the NRA asking them to provide some more information. While it's brilliant that this seems to be going ahead, it's just possible that the problems at the approach to the Jack Lynch Tunnel will worsen at peak times. In my email I've also asked them when they intend to make known their plans for Dunkettle.

    That poster was on the ball, i have to laugh at that thread now that others actually thought there would not be worst traffic problems east bound.

    I still cannot understand how people didn't believe this would happen.

    My error was that I expected it would purely flood back from the tunnel. Turns out that the opening of the flyover has shown up the Douglas flyover as being a seriously weak point in the SRR that will eventually have to be sorted.

    If the tunnel and the N28 gets done, you'll have traffic backed up in both directions going over the flyover.

    When they changed the lights at Mahon slip heading east to an orange filter it had a huge effect on the South Ring at peak times.

    I noticed a new warning sign has been installed to the middle of the N40 Eastbound approx 100 meters before the Rochestown/ Carrigaline/ Ringaskiddy exit. Its one of those traffic queuing warning signs, a sign we will be waiting longer for this Dunkettle project.

    This and the N28 scheme will completely overwhelm the N40 at the Douglas flyover. Will certainly require an expensive widening to 3 lanes in each direction.

    This. The decision to build the South Ring so cheaply is slowly coming back to haunt as 1. There is so many elements of the road that needed upgrading, and 2. Every time some element is upgraded another gets jammed. After the M28 and Dunkettle are sorted there will be a lot more pressure on both the Douglas flyover and the JLT, meaning that the North Ring will surely be back on the agenda.

    I think the tunnel itself will be sufficient for quite some time. The problem at the Douglas flyover is merging issues.

    At a guess, the Douglas flyover is the most heavily trafficked piece of road in the state outside of Dublin. It takes more traffic than anywhere else in the N40 yet it is still only 2 lanes where a lot of the rest of it is 3 lanes.

    Once those 2 new schemes open, the pressure on the Douglas flyover will be intolerable. Expect short term solutions at rush hour such as ramp metering etc.

    IMO, when the M20 eventually comes back on the schedule, you'll see NRR East being bundled with it. NRR West won't be built for years as it requires a lot of tunnels / viaducts.

    But this will always (within reason of course - 15 lane highway would probably be able to host all cars in the county) be the case.

    Once you upgrade one piece of infrastructure, a bottleneck in another one reveals. And the more capacity the road network has, the more keen to travel by car people become, almost immediately consuming that capacity...

    With due respect, grogi, these bottlenecks aren't being "revealed" per se, they're known about know and were predicted in the 90's, but the decision was made not to spend upfront, as such a large infrastructural spend was seen as hard to justify.

    Similar to the metro north, they kind of fudged it, because the politics was unpalatable.

    AugustusMinimus, what do you mean by Douglas flyover and NRR East/West? I presume Douglas flyover is the section passing the village itself (across from the shopping centre) and I presume by NRR East/West you mean from East and from West?

    Douglas flyover is the part between the Douglas west exit and the Bloomfield interchange. Both carriageway are well over capacity at peak times with traffic backing up in both directions. Going west, the Dunkettle and N28 schemes will make things intolerable.

    The completion of the Sarsfield and Bandon flyovers revealed the lack of capacity travelling eastbound with traffic backing up from the Douglas flyover badly at peak times.

    The weird thing is that queues travelling east to Dunkettle have reduced since the flyovers have opened as the queues have transferred back to Douglas.

    NRR is the North Ring Road schemes which are divided into 2 schemes.

    West: N22 to N20
    East: N20 to N8

    East will be built first with west being the last bit to be built. Expect easy to be bundled with M20 south (Blarney to Mallow)

    There's an N40 NRR thread somewhere. Think I put up some images of a proposed viaduct / bridge over the Lee near Ballincollig.

    The road will link in with the current N22 going from the Poulavone viaduct to current J1 on the N40. This section will be upgraded with both roundabouts grade separated.

    Finally, junction 1 on the N40 will be upgraded. An additional bridge will be built with the current dumbbell being converted to a signalised grade separated roundabout.

    A junction with the M20 will be a free flow partially unfilled cloverleaf. The junction diagram should also be in that thread.

    At rush hour a lot of people go via Mitchelstown and R513 to Limerick. With Dunkettle upgraded I can see this volume increasing

    The Douglas flyover is ready overwhelmed.
    It backs up to Mahon slip road every morning heading west.

    If your predictions come to light, increase flow from Dunkettle would make this section heavy, restricting the benefit of any bloomfield interchange upgrade and creating a merge mess that takes a few km to iron itself out.

    I can see Carrigaline -> Bloomfield traffic being tempted to rat-run through Douglas West via the route you've highlighted on the N28 thread, putting them on the auxillary lane for the Kinsale Road roundabout, or merging onto the N40 to continue West. Were you proposing to close the douglas west on-ramp as well as the exit?

    This could fill the N40 west up quickly, though n40 east from bloomfield should be improved somewhat by the dunkettle improvement.

    I was still living in Dublin when they opened the 3rd lane from Donabate to the Airport on the M1. Within weeks the M50 S shenanigans have moved from J6 (Blanchardstown) onwards, back to J5 (Finglas) and often J4 (Ballymun). Moving the whole time, but it one big concertina.

    Removing at-grade junctions has an overall positive benefit on throughput, but upgrading the capacity of intake roads will create a bulky glut of peak traffic. If you're in a concertina, nobody wins.

    I think dunkettle will help eastbound traffic, obviously, but it's going to expose capacity issues along the weakest and busiest stretch.

    I'm with you. At an absolute minimum, a westbound auxilliary lane from N28 to N27 is required.

    Was only thinking of closing the Douglas West off slip. This would be permissible as there's a Douglas East off slip as well. Would be ructions if Douglas West on slip was closed I'd say.

    We're looking at the following I think.

    - Dunkettle and then N28 opens
    - Douglas flyover beyond breaking point
    - Plan put in place for additional lane westbound. This will actually be the more difficult lane to do due to have to build above an existing road. Adding an additional lane eastbound would just require a CPO.
    - Once, done the Kinsale Roundabout will find itself clogged worse than ever. Expect remedial works will have to be done there to improve flow. Not sure what they could do there though to improve the situation. Not sure there's enough space to do much.

    Horror show. The cross merging will be a mess overall, from N28 to N27.

    Carrigaline - Ballygarvan - Fivemilebridge - Ballinhassig relief road anyone? :D

    (Could start with an M28 to Airport spur)

    I've actually been informed that Cork Co Co do indeed have intentions of a new road from somewhere around Carr's Hill to the airport. Badly needed I'd say.

    Is this part of what you're mentioning, AugustusMinimus? Or a separate idea?

    Different project. This is a planned outer ring road to go from the top of Carr's Hill (M28) to somewhere near the airport roundabout.

    Would take a lot of pressure off the Kinsale Roundabout and airport hill.

    This road from Carrs Hill to the N27/R600 roundabout should be built and westbound traffic should be diverted via M28/new road to take some pressure off the Douglas flyover westbound.

    Funny how Cork is developing an outer ring of sorts before Dublin

    I agree with ye lads, a proper link road between the Airport and Carr's Hill/Carrigaline is definitely going to be badly needed once the M28 and Dunkettle Interchange are done. The N40 can be extremely busy as it stands without having M28 traffic being dumped upon it. Also, the flow westbound will be greater once Dunkettle goes free flow during rush hour times, so anything that avoids traffic having to use the N40/N27 during rush hour has got to be welcomed and done as a matter of priority.

    There was a crash on the Douglas flyover this morning and because there was no hard shoulder to move it to, the flow of traffic stopped and traffic backed up as far as the JLT.

    Will this be on the agenda next?

    Sorry, what I meant is that I don't think anyone is going to disagree with you.

    That section of road is already unsuitable for the current traffic volume at peak times so obviously in the future when you have additional traffic from the Dublin road, the Waterford road and the city all hitting it without being delayed at the tunnel it's only going to get worse.

    Anyone have a guess at the build time for this one.

    Unlike with Sarsfield and Band in flyover, the ground here is less marshy and prone to subsidence. However, traffic management during the build is going to be an absolute pain I'd imagine.

    Wouldn't like to be the engineering devising traffic management layouts.

    At present, TII is assessing how best to progress national projects included in the transport element of the Capital Plan, including the N8/N25 Dunkettle Interchange and the N28 Cork-Ringaskiddy scheme.

    AugustusMinimus was right. Traffic approaching the Douglas flyover eastbound in the evenings is now almost as bad as the queue into the Jack Lynch tunnel, and I presume when Dunkettle is sorted the freeflowing traffic westbound will cause a similar issue westbound.

    The next under-built part of the SRR that will be a hot topic when this scheme is done. The amount of money spent on retrospective upgrades to the N40 is simply obscene.

    Ah yeah, but the money spent on the N40 has been to bring up the N40 to the standard of the pre-upgrade M50. The M50 pre upgrade, had grade seperated signalised roundabouts like the N40 does now yet the N40 has had however much spent on it. (Ignoring the new 3 lane sections here)

    Strange one that, is it the physiological thing of going into 2 lanes from 4 or is it caused by those people that shoot up the East Douglas exit and sneak back into the inside lane?

    Neither. You have significant amounts of traffic coming from SRR, the Link and Airport Hill. There is simply more traffic than the current arrangement can handle taking into account merging from the Kinsale Roundabout as well.

    It will be worse IMO going the other way in the mornings when both the M28 and Dunkettle Interchange opens. Loads more traffic and the M28 merging with the SRR just before the Douglas Flyover. I also find the morning rush hour to be worse and more concentrated than evening which will make this one worse.

    I asked a Cork Co Co engineer about this. No plan to do anything with the flyover due to difficult build conditions with the stream having to be dealt with.

    The North Ring Rd would be my next move, along with the M20 construction. Would take any traffic using the SRR as an actual Cork BP, along with possibly N27/N28/N71 traffic from 6 to 12 O Clock clockwise rather than anti-clockwise.

    After the current Cork projects (Mallow relief road, Dunkettle, M28 and Macroom) are done, the M20 has got to be the priority for Cork. Cork cannot wait in the dark ages with no motorway to the third biggest city forever. It would also greatly improve access to Galway, too. Once the M20 is done, Cork will have a proper road not only to Dublin, but all the way up to Tuam as well. That will be massively beneficial to Cork, and will help Cork/Limerick/Galway become a useful counterbalance to Dublin, a kind of 'Western Powerhouse' if you will (similar to the 'Northern Powerhouse' in England, which is actually slowly, but surely, starting to take place with the massive investment in upgrading the rail network between all the main Northern cities and further devolution away from Westminster).
