Highlights are:-
- 8,500 m in length
- type-2 dual carriageway
- 100 kmph speed limit
- 17 structures
- 18/24 month project
- roundabout on N21 (god knows why!!!)
- grade seperation on M20

At the very west of the scheme where the roads goes back north for a section, I believe they may tie in the N21 Adara-Abbeyfeale scheme into this dogleg. Under such a scenario, the route takes seems less meandering

mysterious · 15-03-2010 2:48pm

Why Is'nt it type 1 dual? It has traffic higher than all the current inter urbans.:rolleyes:

What the **** is up with the NRA? Can we have the names of the actual people in the design office. I'm fed up with this carry on at this stage. I'm dead serious. The NRA needs an overhaul.

That's fine. but in the meantime, while we're waiting for the abbeyfeale-adare upgrade, we'll have a roundabout west of adare on the current n21. doesn't this seem crazy?

then again, given that the M20 needs to be built before the adare bypass (or maybe all 1 project (with priority to m20)) - it all seems far off in the future...

No it does not, and will not. It does not compare to the M7 or the M4 or the M1 ( all near Dublin) does it??

To precisely which section of which interurban road are you seeking to compare the N21 around Adare in terms of their current and some putative traffic volumes ???

I think to be fair, type-2 dual carriageway is sufficient.
I'm beginning to wonder though, will it actually be quicker to go through Adare village itself ?

Chris_5339762 · 15-03-2010 9:10pm

I doubt it, what with 120kmh on the M20 section and 100kmh on the N21 section. Versus 80kmh on the old route and 50kmh through Adare itself.

Yes.

And Type 1 is the best solution for a long term cause. It has DC levels traffic and in opening it will rise to about 25000 at least. So many cars avoid Adare at peak times. The bypass wont actually do much good considering its really windy and having a low speed limit like the existing national primary route.

People don't stick to the 80kmh speed limit on existing national primary routes.:rolleyes:

Adare road is more direct and shorter. When its bypassed it won't be bottlenecked. You have two roundabouts on the bypass so its not exactly going to be quick.

The M8 in most parts only gathers 17,000 AADT. The AADT passing through Adare is in the region of 24K, Type 2 dual carriageway has a capacity of 20K. The M9 has about 16K towards Waterford.

The NRA always go for the cheap option on 2+2's look at the Castleisland bypass 3 roundabouts. Compact grade seperaration will be low on these type of projects although there is one on the Dromod to Rooskey scheme on the N4.

Yes its been static for years because its a bottleneck.

Kldare peaked 22,000 a day. It dwindled to 17,000 pre bypass, because traffic avoided the town by diverting to Suncroft, Rathagan, Athy etc.

When the bypass opens traffic will jump. During summer it does peak about 24,000 a day. The mainstreet of Adare already has that number all year around.

Adare in summer is a destination in itself. The AADT West of Adare ...ie the Bypassed traffic is 12500. 12500 is complete overkill for a Type 1.

The total estimated AADT level on the scheme in 2015 is
approximately 10,500 and the remaining volume entering the town from the east is 8,200.

The model indicated that the proportion of traffic on the N21 from the Limerick direction that is passing through Adare is approximately 60%, while approximately 40% is destined for Adare itself.

The Bypass does not deal with "Adare Itself" only with those who want to get the hell out of the place

I would be surprised if end to end ( Tralee Limerick) traffic is any more than one third of the 10500 who will use the bypass on average.

You make sure ring the NRA there and give out like you said you would Mysterious

There isn't a realistic alternative route around Adare.
My point in all this is that we can't go bulldozing a motorway to every corner of the country, just for the sake of it.

Sponge Bob · 15-03-2010 11:20pm

Unlike Claregalway vis a vis Galway it is true that many people visit Adare itself and many of those come from the Limerick side and leave that way afterwards.

The Type 2 bypass is well capable of dealing with the traffic that simply has no business IN Adare and wants to get around it. The same applies to every other town to the west including Castleisland.

I take tech2s point about the NRA messing with a good road design by overendowing it with roundabouts and taking insufficient grade separation opportunities as they arise.

I would also commend those looking at a Type 2 from Adare to Tralee to look at the A11 and A12 roads from London to east anglia which roads carry 50k 60k 70k AADT on what are basically Type 2 roads with no proper hard shoulder really. They are more like Type 2 with a bit of hard shoulder than a type 1 and they come with roundabouts at grade albeit big ones. But they take lots of traffic.

They are all on streetview since last week, have a look.

Oh ffs, get real, the Type 1 and 2 is not going to make any extra impact on ripping up the countryside. If we are going to base your silly assumption on a motorway ripping up the country side, Why should we let a Type 2 DC rip up the countryside.

Why did the inter urbans that has less traffic than this section get a motorway?

West of Adare is much higher. It doesn't drop down 3,4K after Adare. Adare is a village. I don't agree with your bias and inaccurate facts on these road matters at all.

West oF NCW would be about 12,500 approx

I'm getting Claregalways AADT mixed up with Adares!

On the alternative route there is none but only narrow local roads. Some drivers take this route around 5-6 in the evening when traffic is backed up to the WS2 part on the Limerick side. I know that some people take the N20 to Croom and then go to Newcastle West via Ballingarry during the summer months to avoid the bottleneck in Adare. This would not be a significant amount however.

Claregalway is similar. There is a narrow road in Cregboy but the main alternative is the N84.

Mysterious. The 12500 cars west of Adare of whom 10500 will use the bypass is a fact so do not accuse me of bias or inacurracy and then bold those words like you just did.

I don't trust figures from EIS schemes, because they are always lower than the actual figure. Its why they build roads with lower spec quality. Its precisely why they have a roundabout on both sides.

Traffic will drop 3,000 a day just past Adare?. Adare is a village on a national primary route not a huge population centre. Common sense as usual will prevail over nonsense bias and selective non facts. The figures are bull****.

10,500 cars a day wont cause 3 mile tailbacks in Adare. Borris in Ossary has 13,000 cars a day and doesn't suffer from any tailbacks.

I don't really care. Its not that figure. And It seems your not very familar with the area or bottlenecks.

Enfiled and Kildare had traffic static or even decreasing for about 2/3 years prior to their bypasses. When these towns were bypass traffic grew by over 50%

Kildare has over 33,000 a day. Pre bypass 22,000
Enfield. has over 24,000 (9,000 avoiding toll) pre bypass just 23,000

A large amount of traffic avoids Adare at peak times. In summer it swells to 20,000 a day. The NRA figures varies around 16,000 a day. It peaked to 17,700. Since traffic crawls through Adare traffic has not increased and like many counters near bottlenecks decrease. Adare has traffic levels higher than all the inter urbans yet they get grade separate interchanges and a full blown motorway.

I would be happy with this just a HQDC to North oF Newcastlewest, after that type 2. I think its the best solution for the long term.

Those that are estimated as wanting to get AROUND ...not INTO.... Adare are 10500 per day of the present 12500 per day who enter the village from the west.

You are nearly making a reasonable argument for extending the EXISTING dual carriageway R Road (as it will be) right up to to the eastern fringe of the Village there Mysterious

I'm sorry but I'm allergic to this kind of back and forth silly non sensical replies. My point is this. The Adare N21 doesn't drop 2.500 at either side of the village. Its a village. The N21 of 16,500 a day may dwindle down to about 15,500 or a figure more realistic. Anyway all road opening attract more traffic so your figures are just woefully twisted to negate the argument of the real facts.

The fact is, no inter urban in this country deserves motorway status. Bar the Portlaoise to Dublin, Mullingar to Dublin, Galway to Claregalway. Limerick to Adare, Cork to Rathduff. Dublin to Dundalk.

It's near Limerick, Adare, Newcastlwest are growing towns. Its the main route to the SW and it connects to Kilarney, Listowel, Tralee, Dingle and other towns.

The Adare section would be better as Type 1 leaving the rest as Type 2 considering traffic will rise drastically on this route as its bypassing a major bottleneck. It should have the road standard as the Adare northern bypass section. Funny how you don't seem to mention that.

I understand that you may not be familar with this area, but you don't call the shots or actually give the actual facts here. So lets keep it real. You have probably never even passed through the village.

Its not. It's blatant. Look at the Adare Northern bypass scheme which was a standard DC if not (HQDC) with no roundabouts.

The 10.500 figure is a low based count to make this route upgrade pityful and not based on actual figures for actual needs.

I know most people in Ireland don't see the logic of future proofing roads. But I don't design roads based on EIS non facts figures. i base road projects on a 20 year life span at least. With this project it would be more logical to just build a proper standard DC and none of the Type 2 crap.

From the EIS!

It should be noted that in the intervening period since
the initial route corridor assessment the boundaries of the Lower River Shannon Candidate Special Area of Conservation (cSAC:002165) were extended in January 2007 to the River Maigue bridge in Adare. As a result the route for Option 1 now crossed a designated Candidate Special Area of Conservation.

I made my point clear in my last post, maybe you should go back over it instead of taking it out context.

The Adare bypass can demand a standard DC. West of Adare gets 2+2.

If you think it doesn't why didn't you ever campaign agsinst other roads getting motorway status that have less traffic than this section of road. I'm not really bothered about the blue road status. I'm just basing my stance that common sense should prevail and a proper DC should be built that has grade seperated free flowing junctions.

I mean in the next 20 years its very sensible to allow this section Type 1. Why are you so against proper future proofing? I didn't want the NRA to make the Nenagh bypass a S2 but what happens a few years later a total rebuild and millions in taxpayer money wasted.

AS usual you resort to childish responses.

Stick to the facts the ego patronizing trips don't suit you. Your the one that came up with traffic dropping drastically from east to west of Adare. Traffic drops to about to about 13,000 a day a NCW And west of Abbeyfeale its 12,000. It doesn't drop to 10.500 west of Adare. Your wrong. and your just twisting figures around for some sort of agenda that I'm not really interested in or bothered with

The fact is the traffic at Adare is 16000 a day an when the bypass opens it will drastically rise as Adare is now a town not to avoid any onger with held ups. When the Tunnel and M7 and Gort motorways are finished it will also attract more traffic onto this road.

NCW is a town on the N21 Which is one of the fastest growing towns in Ireland and is west o Adare. I don't why traffic would drop drastically at Adare like you posed..

Reading your posts is like trying to be serious but you just can't. The less I would say to you the better. Barna isn't even the topic here. Its Adare.

Interesting how you never stopped any other road in this country getting motorways, but yet here you are ranting and raving about who and where things should be put and done. Adare has higher traffic than all the current interurbans that have been built.

I made my point that Type 1 is sufficient to continue as it did in the previous bypass plans to allow future proofing since the opening year 2012 or whatever date will need type 1 anyway. Now its getting silly with alll these hairy references and assertions of this and that in this thread to make this look whatever way you want it to look.

Do you know that roads are built in other countries to be future proofed. Of all roads been built in this country I don't see why they cant build a proper dual carriegway.

Vast majority of traffic east of Adare go through Adare. Do you know everyone that drives that road?

I don't need to know everyone.

Are you seriously suggesting that more than the AADT through the Village uses an alternative route to get to the West side of Adare.

On the alternative route there is none but only narrow local roads. Some drivers take this route around 5-6 in the evening when traffic is backed up to the WS2 part on the Limerick side. I know that some people take the N20 to Croom and then go to Newcastle West via Ballingarry during the summer months to avoid the bottleneck in Adare. This would not be a significant amount however.

1 more time mysterious- the quickest realistic way to the west side of Adare, is through Adare Village and the vast majority of traffic uses this route.

A very small proportion take the alternative routes as tech2 has suggested.

I'm basing this on facts and my experience commuting through the Village

If it any <cough>help</cough> here is some further data from 2007. Facts are always nice and of course the experts around here may have some commentary to add , particularly on the bits I bolded.

It strikes me that much of this bolded traffic is eminently explicable to an informed commentator in the context of school runs / secondary school runs and the location of supervalu shops.

So basing on traffic growth over two years Rathkeale would be from 13,,700 to about 15,000.

Thats not Adare that Rathkeale, Which west of Croagh again... So the 10,500 figure again is not accurate.

Bear in mind Type 1 motorway handles something in the region of 38,000. Type 1 wide lane motorway is 55,000. it seems really short sighted to stick with type 2 even at Rathkeale, never mind the higher volums at Adare,. The fact that Adare is so close to Limerick it makes sense to have it type 1. Especially given the fact that You have both national primary traffic and commuter traffic generated. Lets not forget the growth of towns such as Ballingary, NCW, Tralee, Kilarney etc from 2007 till now. NCW grew about 55% in the last census.
That would have enormous impact on the future traffic volums counts.

After Rathkeale it seems perfectly acceptable and reasonable to keep it 2+2. I am bewildered why your so against the idea of future proofing a short busier section of road that realistically does demand a motorway more than pretty much most sections of motorway's opened in this country in the last 10 years..

Really strange Sponge Bob. Adare has traffic volumes of 16000. Over a 20 year period would be well over 32.000 if it were based on bypass figures with growth of the towns along the N21 and with the Limerick hinterland growing beyond Adare. Type 1 is needed at least to east of Rathkeale. Infact The Adare bypass should be given motorway status to its end at the M20 with the N21 joining as a fork to the M20. Leaving a another off slip to proceed onto a dumbell interchange to where the current planned junction of the Adare junction is planned.

Bear in mind existing traffic volumes is not the year 2007. We are now in 2010.

Could you send me the link for the 2007 figures. I would look like to look at them.

Thanks.
