Dublin Eastern Bypass feasibility report

20-03-2009 12:34amThis should rile this place up nicely. An entertaining thread awaits.Eastern Bypass Feasibility Study Report
The Authority was charged by the Government with the task of carrying out a Feasibility Study in respect of a possible Eastern Bypass of Dublin.
The attached document, issued in 2007, provides an examination of the feasibility of the project from a policy, economic, engineering and environmental perspective. It concludes that the scheme is technical feasible, strategically beneficial and economically viable, with the economic benefits of the project conservatively estimated at twice the cost.
The report does, however, identify that this is an expensive scheme and the significance of this scale of investment in the current economic climate is fully recognised. As a consequence, the NRA recommended to Government that it would be premature at this stage to make a decision to proceed to construction.
The NRA did recommend that development planning in Dublin does need to integrate the potential possibility of this scheme fully into that planning process. Significant proposals are emerging in the North Port area, the Poolbeg/Ringsend area and the Sandyford area, all of which need to have integrated transport and land use planning at the heart of their consideration. Not to integrate transport and land use planning fully in such processes risks repeating many of the planning errors of previous decades.
While the NRA fully supports the view that public transport needs to be the primary transport mode for these development areas with diminished reliance upon car transport, it is nevertheless the case that a significant element of road provision will always be required for both public and private transport, and that the Eastern Bypass proposal appears to offer the appropriate means, and perhaps the only means, to service that need in these developing areas.
The NRA proposed that the scheme should be further developed to the stage that all necessary investigative work (ground investigations, ecological assessments, archaeological assessments) have been completed and a final detailed proposal developed, inclusive of full public consultation on the proposals.
Out of that work, which would take about three years, would emerge a completed design of a fully functioning route addressing all of the substantial engineering and ecological challenges. At that stage a fully informed decision could be made on whether or not to proceed with the scheme.
Irrespective of the decision ultimately made, the key benefit of this approach is that an accurate and exact provision for the scheme could be integrated into the planning work of all agencies along the route. This would ensure that the scheme would remain protected and would be ready and available for implementation at any stage in the future, if required. In addition, it would prevent that new constraints from emerging that would render the project unavailable, or significantly increase its costs, in the future..
Ancillary to the above key benefit is that fact that moving the project forward to the next stage now will ensure that the delivery timeline for the project would be reduced by three years if a decision is made to proceed with the construction of the scheme at a future point.
Finally, it should be noted that the costs quoted in the report are based on price and cost levels in 2007. Since then land and construction costs have reduced and while this does not undermine any of the report’s analysis and conclusions, it does mean that the costs of the scheme are likely to be significantly lower and the benefit to cost ratio is likely to be further enhanced.

These are really just ideas at the moment - the NRA seem to say in this report that although it shouldnt go ahead right now, it shouldnt go on the back-burner right now.0

Interesting read, thanks. I don't know if I agree with the logic regarding not having a full interchange at the N11. Their logic been to prevent people using the motorway to drive from Belfied to Bray. Of course one way to reduce such traffic would be to have a Toll on this section of the road.
Anyways this is all a bit of a pipedream on the part of the NRA given the current financial climate.0 -
How many more times do we have to fight the Eastern Bypass? It has been voted down numerous times and it should now be consigned to the dustbin once and for all. :mad:0

It is a vital piece of infastructure. You do realise that this would not only ease congestion in Dun loaighaaire, Sandyford, Ringsend, Stillorgan. It would ease congestion on the M50 and westlink and complete the full ring aorund the city.
So if the Westlink closes, you have the eastern section still open and viable to move the traffic around the city. This city is still fairly inadequate in getting motor traffic moving. Cus if the M50 shuts down, so does the city.
I'm a fan of public transport. But even in public transport cities such as Paris and London they have circulating motorways and tunnelss around the city to move motor traffic effieciently.0 -

because as mysterious said it is an important piece of infrastructure that needs to be built. And hopefully after the three years it will take to do the studies they mentioned public finances will be in better shape and they can move ahead with this project.0 -

London - M25, M1. two road tunnels under the Thames. A inner ring,
Paris, - has three orbiftals, the inner ring is mostly tunnells. the third one is actually underconstruction. Paris has many motorways criss crossing vital transport and population points.
Have you ever travelled:rolleyes:
Seriously think before you denote something as fact.0 -

If it's tunnelled it wont need to have a viaduct.
Have you actually read the feasibiltiy report, do you know that there are many route options, and that the sea viaduct is the least likely option. It will be more than likely tunnelled under Sandymount. The idea of building a viaduct out at sea is just stupid.
Tokyo is right on the sea? what is your point. That not have motorways because we are beside the sea. What kind of nonsense is this?0 -
Dublin is not remotely in the same league as London or Paris (Tokyo is even a league apart from them).
The plan is, in short, a crazy piece of nonsense from the 70s or so (probably pre-oil crisis).
Maybe we can worry about this after building the Metro, Interconnector, extending more Luas lines and having sufficient public transport to allow the introduction of a congestion charge in Dublin city centre and further pedestrianisation/bus only routes.0 -

Madrid,
Amsterdam
Brussels
Copenhagen Copenhage has a simalar population yet has two orbitals two city motorway and a tunnel going south to cross over to Sweeden
Stockolm, a city of Islands has a very well connected motorway system.
Even eastern cities such as Burcheresti, have amazing motorways running through them
Seriously Zoney you shoulc check European cities on google earth, it would put our city to shame literally. We need public transport. But we need a motorway system to that in intergrated. We dependd so much on the M50 t0 get around the city. If there is a crash, it clogs up and clogs up all motor traffic throughout the city. Because we don't have a proper intergrated road system. Since Dublin is like most European cities with narrow streets, we do need a proper motorway network to get cars moving aaround the city or through the city without clogging up the marrow streets.0 -

They pay rather a lot of tax in Denmark! Not it would seem, an option here in Ireland, however much it would mean that overall we'd pay less than paying privately individually for things in dribs and drabs to make up for a lack of basic services and infrastructure (not to mention the inequitible nature of that - only those who can afford to do so can make such a "top up").0 -

Have to agree with Zoney on this one. Not that I am particularly excited about the Interconnector but the Eastern Bypass is an environmental nightmare and belongs to the pre-oil shortage dustbin of the 1970s. Peak Oil hasn't gone away you know! Once China and India get back into full swing and oil prices start heading north again road projects like the Eastern Bypass will be seen to be the White Elephants that they are but will Ireland have dived into their construction by then?0

Sydney and thats off the top of my head. What the **** has sea got to do with the idea of planning a proper motorway infrastructure. If sea is an inhibitor for building an orbital, then I don't know what road should ever be built on coastal cities.
Your points are really coming accross as inane to me and don't make much sense. London isn't far from sea either. about 25miles. Your point is?0 -
The real point is that this project should never be built, even if it only cost a cent, because it's hugely destructive to Dublin, will never make a meaningful contribution to reducing congestion, will be hugely harmful to trying to develop a decent public transport network, and if Dublin did need more capacity on its bypass routes it would be considerably cheaper and easier just to widen the M50 again.
Can someone explain to me why this project needs to built?0 -

Eastern Bypass needs to be knocked on the head, stat.
1950s style motorway through quiet areas, bringing huge amounts of traffic to new parts of the city with insufficient distributor road networks to take them. Billions we can't afford - any billions we do have, should be spent on a metro we so, so badly need.
Maybe when absolutely everything else is finished we can revisit, but I wouldn't support this going ahead until 2025 at least.0 -
Has anyone who has conflicting reviews with the report actually read any of it or are they just going with their own preconceptions regardless?0

I agree with everything you said but then you said thisThe real point is that this project should never be built
Your defenition of a "real point" is? if you give a point, please back it up, your post is looking a bit frail in that regard
And when you said this, you've clearly shown you don't understand how transportation works.and if Dublin did need more capacity on its bypass routes it would be considerably cheaper and easier just to widen the M50 again.
It would actually be more expensive and time consuming to widen the M50 again. Dublin does need a full orbital. Widening this road, will still not make much difference to the east side of the city and make much benifet to the M50 other than having more running lanes.
I'm a a fan of Public transport. But Dublin has an inaduquate road transport system. The city is built for car type transport I'm afraid, even though we have narrow streets. The density and sprawl is the type of city where cars are going to be used more often than other types of transport.
Dublin cannot depend on one motorway to carry all motorway traffic and to say it will, is just stupid and retarded.
Do you realise, that all the bridges will have to be knocked if the M50 was widened and you do realise the current chaos it will bring again, good god I think you should leave this topic alone, if you don't please research a bit more on this topic and read the feasbility report
Don't be going saying there is no real point because. Back up with credible and proof.0 -

If it's going to be done, do it in a straight line bored tunnel from Sandyford to the port. Cut and cover where possible, if nessecary close the N11 half at a time and build the tunnel - it'll be worth 2/3 years' disruption. It's the most direct route and avoids an arcing route whose ordinary purpose s to anticipate expansion - but in this case that will never happen without reclaiming a massive load of land.0

Of course it would be cheaper to widen the M50 again - just think about it for 5 minutes - the cost of new bridges and a bit of tarmac, vs. building either an enormous bridge or a very expensive tunnel. The current M50 widening costs 1billion, including 30 years of maintenance and financing the PPP. It will cost 4 billion for the tunnel. Do the sums.
And Dublin does not need any more motorways. The local road network could not handle the traffic, and new motorways would have a hugely detrimental effect on commuting patterns and local congestion. Dublin does not need a ring motorway, and the widened M50 is adequate for the job. It does not need more motorways just because you say so.0 -

No. If there's one thing I don't want to think about, its another M50 upgrade.0 -

Okay it cost, 1 billion to do the current road project. right. I did the maths
Adding one lane, resurfacing 4 lanes. And modifying road interchanges.
New layout would ACTUALLY mean
Adding one extra lane, resurfacing 5 lanes. So that would have cost overruns alone. Knocking all bridges on it's entire length including the new ones. Would cost at least a few hundred million, since you have to replace every single on of them, over moving traffic. Count the bridges from the M1 to Sandyford. At least 25 bridges. Right? Then you have to have greater traffic managment too which is going to cost phenomenal money, since you have to knock bridges. The New Redcow interchange will have to be modified since the old and new bridges are the same width and do not allow for widening. So the new slips will have to go. This is going to cost more money.
It involves widening the Westlink bridge, this mean adding more decks and concrete to create a new bridge over this section, this is also going to cost money that is not under this current upgrade. Removing the loops on the Redow and N4 interchanges as the loops will not fit under bridges once you have 5 lanes each way
You can forget about widening under the Blanchertown interchange. The roundabout has to be knocked, it cannot fit anymore lanes since it's an arch bridge. Cost of knocking, replacing and building a new interchange here would cost at least 130million alone.
So count the amount of bridges you have to knock and manage 4 lanes of traffic while adding another each way while widening it.
Seriously I do know what I'm talking about. The M50 can't be widened and the cost will be at least 3 billion,
you have extra land take.
Modifications of every upgraded interchange
Tarmacing 5 lanes each way
New signage and old signage has to go, since it's won't fit
All old and new bridges currently have to be knocked
Redcow, Blanchertowns, Palmerstown interchanges al have to go more serious modifications
Greater traffic manegment
New Westlink Bridge
More Bridges to build
Environmental impact would be astronomical
The existing Railway and Nangor road underbridges has to be widened too This is serious work.
These are all extra cost to a 1billion price figure. You do the maths now.0 -

You don't know what your talking about, some of your points are coming across as a little retarded, why because there is no base to what your saying or holds any relevance at all. Sorry to say.
You said this:rolleyes:and new motorways would have a hugely detrimental effect on commuting patterns and local congestion
That is the most idotic thing ever seen on this forum and I'm one of the locals on this forum. It really is. Instead of making inane sweeping notions.
Can you please back this up. This doesn't make any sense.Dublin does not need a ring motorway
Every city has to have a motorway system, even the biggest public transport cities in the world has to have them.
There are two types A through way system or a ring way system.
Examples of a throughway system.
Glasgow
Belfast
Examples of a ringway system
Manchester
Birmingham.
A role model for Dublin, would be liverpool since its on the coast. It has a full ring but looks like a c ring since its bordered by the sea, but it has a tunnell leading onto Birkenhead and then goes onto feeding other motorways etc on the other side of the mersey river(whatever the river is called.
You really don't know this topic at all, I'm afraid and to be quite blunt you really have no clue whatsover, here is proof.And Dublin does not need any more motorways. The local road network could not handle the traffic
You said Dublin doesnt need more motorways, yet you said the local road network could not handle the traffic. So if the M50 closes tomorrow would the local traffic support it?
That is again one of the most illogical thing\s I've ever read ever on this forum. It doesn't even make any sense.It does not need more motorways just because you say so
I gave reasons, facts, evidence and valid points in my arguement. You didn't state any points to your claim. I don't think we should build motorways for the sake of it. Most people who know me on this forum knows that. Your not very familar on this topic so you don't know that either. I'm all for public transport, but there is a need to have motor traffic facilitated with an efficient road system to ease cross city traffic and ease the burden on the M50 also. The NRA clearly states that once the M50 is completed it will reach capacity. The surrounding roads were used as rat runs for thousands of commuters avoiding the M50 because it was so congestted. The Eastern ring would give Dublin it's other lung and circulate traffic aorund the city rather than clogging up the western section. The M50 cannot cope as the only motorway and only major road to carry all motor traffic in this city. It would be insane to think like that in any capacity or stretch of imagination.
If your against something that is necessary you need to back up your argument, you havent done so whatsoever, infact you made claims and accusations that make no sense or relevance at al really.0 -

Ok, lets look at the numbers then. The current M50 widening is actually adding 2 lanes - the old setup was 2 lanes plus hard shoulder, the new setup will be 3 lanes plus auxiliary lane, plus hard shoulder. To get an idea of how much it will cost to add another lane, forget the 1 billion PPP cost of the existing widening. That 1billion covers the widening plus 30 years of maintenance, and all the large junction upgrades and will include 2 further resurfacings of the road in years to come. The capital cost of widening is much less.
A very similar project across the water, where all bridges had to be knocked is the M1 widening project from London to Luton, widening from 3 lanes to 4. 10 miles of widening cost £300million http://www.cbrd.co.uk/futures/scheme.php?id=138. Construction and land costs are similar there to here, so the costs should be about the same. Since the whole M50 is about 30 miles, the cost would be £900 million to do a similar job on the M50. This is about €1 billion.
But that's not really relevant. I drive on the M50 regularly at rush hour, and the parts where widening is finished move freely now. The bottlenecks are at Blanch and Ballymount where the road narrows. Once these are removed, the M50 will be perfectly sufficient for Dublins motorway needs for the time being.
But the question I'm asking is - what journeys does this provide that aren't currently catered for? The only two I can see is going South to North via the port tunnel, which is catered for by the M50, or going from South to the city centre. A city centre we have spent 15 years trying to remove commuter traffic from. What is the compelling reason for this motorway? Whose lives will it improve? What strategic journeys will it allow?
Because I can tell you what it will make worse - the people living next to it will be forced to deal with the traffic and community severance a large motorway brings. Dublin commuters will have to wait longer for good public transport, as funds are pumped into a road network that will always be inadequate for the demand. Or those of us that have to pay for this white elephant, which could easily buy, and take your pick:
-A high capacity metro system for Dublin
-The interconnector, plus electrification of commuter lines in Dublin, plus 4 tracking of the northern line, plus improvements to the Cork and Belfast lines to give travel times of <2hours and <1.5hours respectively, and proper suburban rail networks in Limerick and Galway with dual track to Limerick junction and Athenry.
-Every other important road project in the state: the Cork Limerick motorway, the Limerick Galway motorway including Galway bypass, sorting out Newlands cross, and the Cork south ring road roundbouts, and building a bypass around New Ross, Enniscorthy, Adare, and improving the N24, N4, N17 and N25.
Can you really say that this is a priority compared to the above projects?0
