Tootenhill (4A? - west of Rathcoole)
Future Leinster Orbital (10A? - west of Naas)

Since the stretch was renumbered only a few years ago, this really is ridic.

It already has an A suffixed "junction" at Citywest (3A).

Not heard of a future junction at Tootenhill but there is going to be one for the Sallins bypass/Osberstown at some point also, 9A I'd assume.

You're right - I only just noticed that the pair of LILOs west of the main Citywest junction (J3) is labelled 3A and indeed appears on signs.
I forgot about Osberstown. I presume this is dead until the property market stages a comeback.

In fairness the numbers on the junctions between Naas and the M50 are fairly random because the original plan was for a new M7 to run from Naas to a new junction on the M50 (Junction 8) and not along the Naas Road. I would imagine that had that plan been carried out we would have properly numbered interesctions (1 to 8) along the way although I've never seen any plans for that proposed route. Are there any out there?

Once the plan was dropped following the widening of the Naas Road they just numbered certain junctions to fit. It does seem odd that they left out a possible number for NX but as they were short numbers already they probably just decided to go with what the obvious properly designed interesections.

I reckon the 3A designation was added purely to distinguish between the junction for the Citywest Hotel as opposed to the junction for the Citywest Business Campus. It was definitely a later addition.

Even at that there are some small junctions on this route that don't have any designations. Inbound there's a junction for Baldonnel just before the Citywest junction that isn't numbered. And there's a minor road join just before Newlands Cross that doesn't have one. I think there's another one further out but I'm not sure about it. Outbound there's the one you mention at Tootenhill.

With regard to future proofing that's kind of hard to predict. Yes I know the Leinster Orbital was talked about but had any form of real planning for it taken place. As far as I remember it was still a proposal even at the height of the boom. I can't see it being built now for at least another 20 years.

Its kind of hard to leave gaps because you think there might be a junction at some time in the future. And if time does overtake your plan then is putting in an "A" junction number such a big deal.

Osberstown Junction is built and open according to Googlemaps

[invinciblePRSTV]

So anyway, back to the N40......

...of which we as yet have no news.

I submitted a change request to Teleatlas, but they're usually useless.

N25 being changed to N40 confirmed here.

From N22 at Ovens/EMC interchange to a point east of Carrigtwohill the tunnel.

I cannot imagine the N25 from the tunnel to east of Carrigtwohill will become the N40. Perhaps there will be signs on this road giving advance warning of the N40 coming up.

Very interesting.
So we will have primary route numbers changing as we drive along the same primary route, the only other occasions I recall seeing this happening is crossing international boundaries.
Is Cork finally being granted its own Republic status

After re-reading it, I think you're right.

Would it not be a better priority to spend what limited cash there is on fixing (re-fixing the recent crap attempt) the surface disintegration of the westbound carriageway of this section than putting the money in the pocket of Mr Rennick for a project which will do nothing for the driving experience along the said stretch of roadway.

[Amtmann]

I wonder what the rationale for the change is.

I think this rules out the N40 becoming a motorway in the medium term.

[munchkin_utd]

we definitely had our eye off the ball on this one
Here IS the definition of what the N40 is

N40
Cork Ring Road
Between its junction with N22 at Curraheen in the county of Cork and its junction with N25 at Dunkettle in the county of Cork via Ballinaspig More, Ardarostig and South Ring Road in the county of Cork: South Ring Road in the city of Cork: South Ring Road and Monfieldstown in the county of Cork.

S.I. No. 53/2012 — Roads Act 1993 (Classification of National Roads) Order 2012.
"Notice of the making of this Statutory Instrument was published in “Iris Oifigiúil” of 28th February, 2012."
http://www.irishstatutebook.ie/2012/en/si/0053.html

So in total it'll only be 15km long

I would assume that the n25 will now go on to cork city via tivoli eliminating the n8.

It would make more sence for the n40 to go all the way to the model farm road roundabout via the current new bit of n22 dual carriageway. If/when the northern ring road is done the n40 would be a complete ring.
