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

Two questions. How many cars use the N40 as a through road (e.g. M8 Michelstown to N22 Macroom via N40). Likewise, how many cars on the N40 start and end their journey using the N40, without going further west than Ballincollig or further east than the tunnel?

I do seriously question how many cars will be taken off the N40 South once the N40 North is done. The only real benefit would be W-NE (i.e. N22-M8) and E-NW (i.e. N25-M20). If you’re going from Ovens to Little Island, it’s still easier to go on the N40 South, and you’ll need to use the N40 regardless to get to the N27, N28 or N71.

As I keep saying, so long as the N40 South goes through the southside of the city with multiple exits, as opposed to around the city like the N40 North will, the N40 South will always primarily be a distributor and not a bypass. An Outer South Ring (N25 Little Island - N28 Ringaskiddy - N27 Airport - N71 Viaduct - N22 Ballincollig) is badly needed. Outside of the N25-N28 bit, it should all be relatively simple terrain and greenfield. Avoids the tunnel, connects all industrial areas, has connections to all national roads, and most importantly, would not be attractive as a distributor road. Through zoning and limiting junctions, a protected corridor could be built along the route to prevent another N40 South situation

Another benefit of the Outer Ring is the removal of the need to widen J9 Bloomfield through J7 South Douglas Road, which I can’t see being possible without serious egg breaking

N40 North is definitely needed, M20 being constructed or otherwise. My issue is more that I don’t think it will take enough cars off the N40 South to make much of a difference to usage levels

But that’s just me guessing, I could be wrong and the modelling could say otherwise

I think you're right.
I believe if we improve the N40 South to any further degree then the additional capacity will just be used up by commuters. I believe for the N40 South the only option now is removing commuters: better options are needed (faster, cheaper, more convenient, more comfortable). But extricating people from cars will extremely difficult.

I'd be in favour of N/M40 North and maybe some kind of backwards multi-point tolling (short distance users high cost, true long distance commuters no cost). Try and cut the Douglas-area usage by all means possible while providing capacity elsewhere basically.

North ring road is needed. However, the main solution to this issue is a comprehensive Cork metropolitan area wide public transport solution. The DKI and N40 bottlenecks are caused by commuters that could and should be using public transport, if it existed. While the CACR will have some impact, an extended rail based rapid transit system is needed. I don't see this happening, as the local political will and general public world view will not support it.

The LUAS proposal and bus connects, even if implemented, will be inadequate; as there is far too much pandering to the motor lobby, NIMBYs, and other vested interests. Cork is no longer a small city, yet it retains a small city worldview when it comes to transportation, and this is perhaps the biggest obstacle to solving these types of issues.

Not sure if this is the correct place for this but it does directly impact on the Dunkettle junction as it seems to include a proposed upgrade to the existing Dunkettle roundabout. Mods, feel free to put this somewhere else if necessary.

Has anyone else heard about this? Nothing on the POCs main website I noticed.
