    No you are not.

    Out of Cork, the N20, N22, N25, N28 and N71 are all above the threshold for dualling.

    Any updates on plans and design?

    Yes you are missing something.

    M9 is a more important route, nationally, as it connects Waterford to Dublin via Kilkenny, Carlow and onward to M7, the major approach road to Dublin. N25 is less important, as it connects Waterford with Cork (okay, Rosslare harbour with Cork!), a much smaller population centre, and only Dungarvan and Youghal in between.

    Traffic volume on M9 might be lower, but the type of traffic is very different. M9’s is more evenly spread throughout the day - also note that the “% HGV” is twice that of N25. That section of N25, on the other hand, has extreme peaks in morning and evening, but is very quiet at other times (I know, because I regularly use this road, and I make sure to avoid those peak times).

    The plan for this part of N25 is a 2+2 dual carriageway, but the very high traffic on this road is not a sign of population growth that must be accommodated so much as a dysfunctional housing market that has forced people who work or study in Cork to live very far away from the city (that annual figure will drop a little as the year progresses and the months without students are included in the total). The only thing driving traffic growth on this road is a lack of housing closer to Cork

    Every road is important for the people who use it. So I’m not following how one road can be more important than another even though fewer people use it. You say it’s more important “nationally” but I’m not clear what that word actually means in this context because a nation is ultimately just a collection of people. And if the N25 is important to (i.e. used by) more individuals than the M9, that surely makes it collectively a more important road.

    That’s not how it works, and you know it. If it was, there would be no wide roads outside of Dublin, Meath, Louth, Wicklow and Kildare, because that’s where “more individuals” live.

    The “National” in National Road means that it is important to the transport needs of people all across the country. There’s no special context here: “National” as in “National Concert Hall”, “National Development Plan”, “National Gallery”, “National Archives” - for the use of all people in the country (seriously, when you’re trying to redefine the meaning of words, you need a stronger argument). N25 is a national road, but it connects smaller centres than N9, so is of less importance nationally. That’s the beginning and end of it.

    That section of N25 has long needed an upgrade to bypass Castlemartyr, which has become an unhealthy place to live due to constant traffic, but it is primarirly a commuter corridor from the Mogeely-Castlemartyr-Garryvoe outer commuter belt to Cork City: 30% of traffic here is gone after Castlemartryr. The road is going to be upgraded, but if you’re holding out hope for a motorway, don’t. This will be a 2+2.

    This should have been started a long time ago, but Cork County Council decided to champion a widening and extra residential access on the current N25 from Midleton to Glounthaune (that went against their own environmental and land use rules, but sure whatever…) rather than addressing this road. It’s good that this project is finally getting attention, but it should have been started 5 years ago.

    You threw out the word nationally as a sort of trump card to magically override the empirical reality that the data are showing. If you’re going to claim that something is nationally more important there needs to be evidence to support that. I don’t see the evidence.

    25-30 years ago, civil servants living in Dublin made a determination as to which of the N roads were more important than others. Funds duly flowed and we now have a gloriously centralised motorway network - completely over-spec’d in many places - and mostly crap roads elsewhere. So I can’t help but wonder if the determination of those Dublin-based civil servants might have been a little blinkered, and that the daily traffic flows are what really defines importance.

    On a more technical point, you say the N25 is less important because it connects smaller population centres and you assert that this is, “the beginning and end of it.” Not even close. One of the most basic and yet useful formulae in road planning is the gravity model. This relates the required capacity for a road between two population centres to:

    (Pop. A * Pop. B) / Dist. Squared

    In other words, the distance between two centres has a much greater influence than the population of either centre. Cork, Carrigtwohill, Midleton, Castlemartyr, Killeagh, and Youghal are very close together. You can’t just say “smaller centres” and drop the mic.

    Why is N9 a motorway and N25 not?

    = How many people live on both ends of these roads?

    = How many people live in the catchment of these roads?

    = How much of the traffic is heavy freight versus passenger cars.

    That last one is important.

    I really don’t have dog in this fight. In fact, I use N25 far, far more than I ever use M9. You are the one who came up with a bogus argument based on single-point traffic figures. We all know M9 south is over provisioned, but the Northern end is not, and it is continuity with this, plus the relatively high HGV share using this route that tipped to balance for it to be a motorway all the way. The middle of N25 gets pretty quiet too, you know.

    It is a national network, not a local one, and N25 is only heavily trafficked in the part that serves as a local route into and out of Cork city. Cork County Council has a long history of funnelling Cork City’s local traffic onto National roads in order to shift these roads out of its own budget: they even lobbied for the Cobh road to be upgraded to a National route!

    Any danger we might talk about the actual N25, rather than complaining that someone else got something you think they didn’t deserve?

    I really don’t understand the relevance of the number of people living at either end of the M9 or in the catchment area. Even if it was 25 million it wouldn’t matter if none of them ever drove on the road. You equate the importance of a road with the theoretical potential for traffic (all those people in Dublin) where I equate it with actual traffic. But hey, I acknowledge the freight issue. That’s a relevant data point.

    Catchment is the primary metric that is considered when building any transport corridor. And you're still looking at things solely from the point of view of private motorists... they are not the most important users of the road network in terms of the operation of the country... almost every single thing you buy in this country has been delivered by road.

    Waterford is a city and a port. Its connection to the major population centres on this island is important. Until 2009 that connection was N9, a road that makes the current N20 look like a freeway. That road and its alignment was so inadequate that a completely new route was needed. That route was built as what is now a motorway so that it would not need to be revisited for a very long time (there was a bit of string pulling to get it moved up the schedule, but "high quality dual carriageway" was always the most likely plan.. HQDC roads were all then redesignated as motorways).

    By contrast, N25 in East Cork has always been a "good" road, with the exception of needing to go through Castlemartyr and, to a lesser extent, Killeagh. That reduced the need for a complete replacement. A bypass of Castlemartyr would dramatically reduce journey times, but it keeps getting postponed... the County Council has never pushed for it, so TII isn't going to prioritise it off its own bat.

    Given that the traffic has eased considerably since mid-June, a better fix for the current traffic would be affordable student accommodation. Accommodation in general is the biggest driver of Corks outer traffic problems: the jobs are all around the city, but people are having to go as far away as Youghal just to be able to afford a roof over their heads.

    Tender for Consultants to take scheme through TII PMGs Phases 1 to 4 has come out via a Framework

    Excellent. Once money is being handed over, there’s more chance of a scheme continuing.

    Is there any clue about the scope of the project at this point?
