N8/N25/N40 - Dunkettle Interchange [open to traffic]

Also Little Island south roundabout to N25E. Embankments for that require closure of the current N25W to Tunnel exit to the roundabout.

I’m genuinely stunned at the progress on link F. Could be opened within a few weeks. Surfacing on the link is now going full steam ahead.

Could well coincide with tunnel to city link opening at same time.

Should do as there wouldn't be any traffic crossing that point. Assume they'll(the lights) move to the Link F section where it joins.

Steady progress.

Id say a lot of the works will be done in the next 6 months, especially when the good weather hits.

How will traffic eventually come from M8 towards city, if the roundabout is going to be closed off? I can't make it out on the plans.

Ah ok, so going the opposite direction initially! Cool, thanks for that.

I wonder would many people just get off at M8 at Glanmire and drive through instead? I suppose it's not that much of an inconvenience though....

Aslo, I drove to Dublin on Saturday and took the new slip after you come off the Dunkettle roundabout (Glanmire) and the length of road to feed onto the M8 is very short!

I think the opposite. I don’t see any major issues. If anything, the more free flowing nature of the junction will lead to tailbacks from the Dunkettle Roundabout now that it has traffic lights.

I think you’re talking about two different places..

I reckon "movement" is a particularly apt word when going from M8S to the city centre because it's akin to a messy bowel movement. People may well say that most M8S traffic goes to places other than the city centre but I think many people are going to find it weird that when travelling to the city centre they have to negotiate two roundabouts, one of which has a pedestrian light at one of its exits. I can hear the conversation now... "Yeah the drive down was grand but I think we took a wrong turn somewhere because we ended up leaving the main road."

Yeah 4 roundabouts in 900m, sharing with pedestrians and cyclists on the main Cork to Little Island route, road which simultaneously shared with the main Dublin to Cork road just seemed a little bit optimistic to me.

We'll see in time!

Yeah, I acknowledged that the traffic volumes are higher on the other movements. But I think it’s fair to say that the route via Tivoli, Silversprings, and on along the quay would be perceived by most non-road nerds as the main road into “Cork” from Dublin. So for that movement to be convoluted will feel like a mistake to many (or that they have made a mistake driving).

Regarding your point about the N40 North Ring further reducing demand, that may be true. But I would counter by saying that the Gateway Bridge from the Skew Bridge to Centre Park Road will serve to increase traffic going west from the new interchange.

Do you mean "has more traffic than M8 to City"?

Many are rat-running at present! Many cars avoid Dunkettle daily. You see them coming through Watergrasshill in the morning, and also coming off the M8 at Sallybrook/Killylough junction. People from Fermoy/Watergrasshill/Mitchelstown directions avoid Dunkettle by rat running through Glanmire.

Strongly agree with this. I think that new bridge idea is crazy. A new high-density urban area with the primary city access road through the heart of it? Almost unbelievable.

As I say above, I believe those traffic counts were artificially low due to large volumes of current rat-running. The M8 is supposed to bypass Glanmire, but it's now feeding traffic directly into and through Glanmire. That feels like a terrible mistake, to me, and the Dunkettle "loop" design will exacerbate the issue. An N40 North is needed to resolve the issue of anyone from Dublin wanting to access the Northside, and also for anyone wanting to bypass the city to/from the N/M20. Unfortunately it will likely be a long way off

New video has a great view of the progress made on the City to Tunnel loop.
