Motorway Junction Maps/Schematics

darkman2

New and proposed junctions as well as existing ones on some motorways can be found here. The NRA put these on the website.

Good stuff. Looking at the Jct. 1 layout on the M8 (M7/M8) reminds me just how Dublin-centric Ireland still is.

Why doesn't that junction allow for all movements? The M7/M9 junction and the M4/M6 junction should be the same.

These are absolutely excellent.

Did the NRA always have these up or were they only added recently?

Just noticed they've got time lapse videos of some projects on the same page.

I wonder what kind of pics, vids etc the NRA and contractors took during (pre-)construction?

I would say - only added recently. I tend to keep a close eye on their site and never noticed them before either

M8 junction 8 is wrong.

M7 J25 seems to be missing an off-ramp heading East. In general, though, a very handy reference. They also answer the burning question of where R448 becomes R418 at M9 J2

Hmmm, I find the maps rather child like tbh. Crappy photoshop sort of effort. Motorway strip maps should be like those in the AA members handbook used to be. They do the job, but not in an aesthetically pleasing way.

So after spending god knows how many billions constructing an inter-urban motorway network we are left/will be left with:

1. A Dublin - Waterford motorway that ends in a roundabout with a crappy little link road over to the N25 and more roundabouts.......

2. A Dublin - Galway motorway that ends in a roundabout (until the outer bypass is built in about 10 years time)......

3. A Dublin - Cork motorway that ends in a signalised mess of a junction at Dunkettle.....(with the chaos of Newlands Cross to last for at least another few years at the other end)

4. A key interchange between the M6 and M17/18 at Rathmorrisey which isn't even full free flow. (How come the interchange on the Limerick Ring Road at Rosbrien got what looks like a proper freeflow?)

Yeah, freeflow facilitated by them cutting off city-bound access onto the local road network except from N7 eastbound. There's going to be rather serious trouble over this when the general public (and even some current local politicians and businesses) catch on to this!

Also at design time, the downturn and Dell closing would not have been anticipated, and probably extension of M20 to Cork was factored in.

What's going on with the M9 at Kilkenny? two N10 roads one at J8 and J9 (S)

There's already some rumbles about it.

People will go crazy when the road finally opens and they'll have to go the long way round (Dock Rd or Ballysimon, or get off at Dooradoyle) when coming from Cork/Kerry side. It was a big oversight.

It's the same as the current set up albeit on a smaller acale in the future.
Presently the N10 departs from the N9 at Paulstown and goes onto KK to form part of the main ring road and then on south towrds Waterford to again mee the N9 once again at Ballyhale. The N10 in future will be just a short feeder N route to the M9 in reality.

It wasn't an oversight. The access would have been provided but for interference at the planning stage years ago.

Can someone explain how Junction 8 on the M9 works? You're traveling eastbound along the N10 which seems to lead inescapably to the M9. There's no roundabout or junction of any description. What does non motorway traffic do? Make a U-turn??!!

Or will this road be signed M10?

KevR

The junction layout maps look really good.

There's a mistake on the M50 J4 (Ballymun) map though. There are arrows pointing onto the M50 clockwise (but in an anti-clockwise direction! :eek:) from the R108 Northbound!

Danno

I see the N77 will continue from Durrow onto Portlaoise also.

Interference by whom?

To the best of my recollection, local councillors lobbied against this on the grounds of it bringing too much traffic into a residential area.

I would say that it probably is not a bad thing.
The N20 northbound alone has a traffic count heading into limerick of 1400 vehicles per hour.
That has to be at the limit of what that road into the city centre can handle.

The restriced junction prevents N7 traffic from competing/ hindering the N20 traffic getting to town.
If you had a merge of N7 traffic both east and west, along with the N20 traffic it would be a nightmare, AND you could well end up with traffic on the N7 queing/ sitting in a jam trying to get off at that exit rather than the one either side of it.

For once maybe Ireland is planing ahead to avoid problems in advance!!

Sure 'twill do... :rolleyes:

...for now at least. The Quarry Roundabout is a good big one and I'm sure it will be well able to handle current traffic volumes once the M9 opens. However, give it a few years and you betcha it will need traffic lights. Then it will turn into this:

So yeah, it's grand for current needs, but with a little forethought and a little extra cost, it could have been future proofed.
