How would they get to the roundabout? Are you suggesting the slip road that goes from the west (Cork) to the north (Dublin) be two-way? That would be a barrel of fun - not.

How would traffic get from the M8 to Little Island?

Give me a few mins to draft a map.

Iv come across a problem. What to do with the Glounthaune traffic. You probably couldnt send it to Dunkettle without having a bridge that runs parallel to the N8 between Sarsfield and Dunkettle. Here it is anyway (excluding glaunthaune Traffic)



How much traffic uses that offslip to Glaunthaune?

Hogzy,
There's a large industrial estate serviced by that slip road including all of Iarnród Eireann's freight depot. Also, a significant amount of the Glanmire and Glounthaune population use it. But realistically the freight depot is the biggest user of this. The image you drew even shows a little of it.

Yeah but there is another exit they could use further up the N25 (the second exit for Little Island). They can just use that exit. Its not as if thousands and thousand of cars need it anyway. IMO getting rid of the Glounthaune Slip is justified to ensure a free flow M8 to Cork City Center route.

Glaunthaune traffic can be rerouted to the Little Island exit on the N25 (which can be widened if needs be). The N25 is already 3 lanes as far as that junction anyway so it could cope with the extra traffic.

I don't disagree that the slip could be gotten rid of if the Little Island junction was improved. However, the Little Island junction has not got a lot of extra room on either side and backs up considerably at peak times as it is, on the "old" road and within Little Island.

In terms of comparison with the other roads concerned, it certainly is the least significant, but I think you really need to see the numbers before you can say the Little Island junction could survive the extra traffic. IMO it wouldn't.

But look, my point over all others, the proposed dumbell interchange east of the dunkettle interchange is inadequate for intercity traffic.

Hi folks,

There's now a brochure (PDF File - 1618KB) by Jacobs on the preferred option.

Great to see this progressing but doubt funding will be in place to pay for the CPOs.

Do you really think it would be that dear? We just need money for the land.
I agree though, Varadkar's the Minister for Not Building Transport so he seems determined to do as little as possible.

I would prefer that version of the scheme NOT to progress.

If this option was to be built, I'm guessing they would signpost the route to the city centre on the M8 via the N25 South Ring and N28 South Link instead of the old way via Tivoli.

It could be argued that they are future-proofing and I can see their point with the new North Ring Road to take traffic away from the interchange and the Port being moved to Ringaskiddy there would be little need for the majority of traffic to have to take the old N8 road. The problem with this is that while it would save money, it will cause problems in the short term and let's be honest the way the country is now we might not get the North Ring rd and new Port until a decade after this is built

IE's freight depot, North Esk, has been disconnected from the line for a couple of years now, it's closed, so I wouldn't worry about traffic going there.

I think munchkin and others have made excellent points about the M8 - Cork City traffic clashing with traffic into Little Island. I mean, obviously there's been a lot of work put into the plans by experienced people, and we don't know what the current and predicted traffic volumes on those routes are, but from observation and from experience I can't believe that the (aptly named?) dumb bell junction will be anything but an impediment to traffic and probably downright dangerous.

Does anyone know of an official petition against the current design? When is it supposed to be going for planning approval?

I think the design has to be modified to make traffic into Little Island and from the M8 to Cork City free flow. What I think we need is bollards! Lots and lots of bollards. I've gotten the crayolas out again, but this modification is fairly counter-intuitive so bear with me....

[edit] I've thought about it and think I can make it simpler - new drawings in new post. [/edit]

The problem with Dunkettle is the Little Island junction. So lets close it, move it and split it. That allows you to FULLY Grade Separate Dunkettle and improve capacity at Little Island. Glounthaune gets a hybrid style half junction. Put these midway between Cobh and the current Little Island junction. Avoids a lot of weaving.
