..those cloverleaf junctions are no longer the in thing - they're only suitable for low traffic volumes switching between motorways. IMO, it should be a directional-t (3 level freeflow) with some provision for access to Limerick's Inner Ring Road. After all, it's the junction between the Atlantic Western Corridor (AWC) and the M7 Major Interurban (MIU).

oh yes I forgot the alantic corridor, they use them in the states surely they would work here.

which one if any would work, also note the similar m7/8 interchange halfway down the page, this one would give access from m7 to m8 or both

Regarding Rossbrien, my long-term solution would be to super-impose a semi-directional t over the existing complex. This would provide fast connectors between the N/M7 and M20 highways. I would then scrap the M20 North to M7 East loop and N7 East to M20 South connector and divert the M20 slip (beneath the M7 flyover) towards the city. There might also be room for a new M7 West to City connector.

What you would end up with is a hybrid of a trumpet junction (level 1) off the N/M7 highway (level 2) towards the City, with a semi-directional t (levels 3 + 4 overhead) facilitating the movements between the N/M7 and M20 towards Cork/Tralee (N/M21). Now, that would be something to see from the air!

We can never seem to build proper interchanges in Ireland.

Conspiracy...

...well FF and the Builders have long been suspected of being in bed together - oh, and isn't amazing that Seamus Brennan was moved from the Dept of Transport to his surprise (don't think it was anything to do with terminal illness then) - after all, he was not exactly the Builders' friend - he wanted value for money when it came to road projects!

In any case, wouldn't underpowered interchanges be something for the boys to do in the near future! :mad:

Cloverleafs + Irish drivers = Unmitigated disaster. I'd rather they built a second Dunkettle than do a cloverleaf.

I've been on cloverleafs in the US. Cloverleafs = bad idea, full stop.

don't know if anyone else has noticed but according to this nra link (nov 2009) , the n7 tunnel will be n18 not n7 from the rossbrien interchange! makes sense me thinks.:)

Yes it does, The M7 terminates at the Rossbrien since the M20 and N18 naturally feeds onto the M7 it makes sense.


The only thing that is awful is the Rssbrien. The interchange should have double sized loops and motorway near speed flyovers.

They will have to fix this junction anyway AGAIN. The on slips and lane gains are pity full to start with. The Dooradoyle interchange will not be able to cope with all the city bound traffic diverted at this junction. The M20 should be 3 lanes each way from The Dooradoyle exist to the Rossbrien now.

Does anyone know how long the clonmacken road is going to be out of comission from the Clonmacken roundabout. A bit of a pain for Knocklyon, Cluain Dara residents having to go down by Ivans in the morning.

No idea,its incredibly annoying tho living in Cluain Dara at the moment.

sorry if this has been answered already, but anyone know why they are installing toll booths instead of freeflow??

A free flowing toll system like the m50 is very expensive to install and cant be justified for a less busy project such as the tunnel and the other PPP projects. There will be a tag lane i assume so there should only be a slow down, not a stop.

signs are up on the SRR beside the Crescent Shopping Centre (R526 overbridge). Haven't seen the front of the signs, just the rear from the bridge. One should be able to see the eastern signs from the shopping centre - presumably green all the way on that sign unless there's been some last-minute change.

One can also see the cantilever sign for the offslip to M20 in the distance to the east. It's a blue sign with a white patch for the city centre (presumably the start of the off-slip with lanes for both destinations is M20 despite the city centre slip breaking off almost immediately after coming off the SRR).

they were out doing them the other day

In the Limerick Leader this week, the toll was confirmed to be €1.80

Interestingly, no opening date is fixed and it seems that the training day for the emergency services has not yet occurred...

Also from the article, you wont be seeing cyclists etc. using the tunnel (which was a question that cropped up before).

According to the draft bye laws pedestrians, cyclists, sulkies and tractors will not be allowed to use the tunnel and height and width restrictions will apply to trucks and commercial vehicles.

Clonmacken Roundabout is back open to traffic from the clonmacken road.

I doubt pedestrians and cyclists would be interested in sharing the tunnel with all that traffic anyway, for safety and comfort reasons.

the actual text of the bye laws is here:
http://www.nra.ie/PublicPrivatePartnership/TollingDocumentation/file,17052,en.pdf

heres who cannot use the road

8 RIGHT TO USE TOLL ROAD AND PROHIBITED USERS

8.1 On paying the Appropriate Toll to a Toll Collector or by means of a Toll
Collecting Machine including without limitation by means of ETC, the driver of
a Vehicle referred to in Regulation 2 shall be entitled to use the Toll Road.

8.2 Pedestrians, pedal cyclists, animal drawn vehicles and agricultural vehicles with a speed less than 50kph and motorcycles of less than 50cc engine size are
prohibited from using the Toll Road.

and like other new schemes regular users (somehow) can pay in advance and get a few cent saving.

15 DISCOUNT FOR MULTI-JOURNEY PREPAYMENT

15.1 A discount of at least 10 per cent of the prevailing toll charge shall apply in
respect of pre-payment for 20 journeys or multiples of 20 journeys.

This is Limerick FFS . Nobody enforces traffic regulations against knackers and their horses and traps. Of course they will go into the tunnel any time they feel like it and of course nothing will be done about it.

If you see one coming up behind you in the tunnel then drive very slowly and produce LOTS of Carbon Monoxide as you do

Cloverleafs are dangerous everywhere and are pretty much obsolete as an interchange design. Of course in some countries they still have loads of old ones built several decades ago.

A combo of two cloverleaf loops and two direct ramps (a la 4-level stack) would have been best for Rossbrien.

They'll follow the law like everyone else. If they go into the tunnel, overtake them and stop your car to block them if necessary.

You would probably get a hammer through your back window.

Does anyone know when the emergency services simulation emergency is going ahead?

activity on the main line at the crescent shopping centre going west, looks like the final layer going down
