Afaik initially it will be only to segregate the businesses and garage from mainline traffic.
Im still unsure though how they have the space without needing additional land. Even at present if a large truck is exiting it needs to swing into the lanes of traffic to make the turn.

I wonder were there any conditions of the planning for the new cherrywood development to allow for upgrade of the remaining m50 to 3 lanes.

I agree, I can't see how they're going to squeeze it in either. I've been looking for some detailed drawings online but can't find anything.

I wonder how much of the N11 they will be able to redeclare as motorway when this is done. I reckon probably only J11 (Kilpeddar) to J14 (Coyne's Cross). North of that you have to make way too many compromises on alignment and slip lane length.

What 2 lane M50 section do you mean?

Its a hard one to know, could be issues with the bus stops in Kilpedder and at Coynes cross too.

Regarding the 2 lane m50, i presume they are talking about the section from Loughlinstown to Sandyford.

I reckon they move the bus stops and bus route onto the old road. More convenient for residents.
I thought the M50 from Bray-Sandyford was getting widened along with the Bray bypass widening. That was the plan at one stage anyway. Maybe not anymore. That section isn't used anywhere near as much as the rest of the M50 except at rush hour.

prunudo

Problem is there is no old road or alternate route southbound for the 133 to go. If they make it motorway and close the stops its only encouraging more people to use private car and abandon the bus service.
In an ideal world it be great to have it motorway but there also needs to be thought given to public transport solutions.

No, Phase 1 is just an upgrade at Kilmacanogue. The rest is in Phase 2 which will be more costly. Phase 2-4 are being appraised for potential inclusion in the National Development Plan.

Yes. At the M50/M11 merge you basically have 4 lanes merging together as the 2 lane M11 merges with the 2 lane M50. This is more of an issue and the primary issue up for solution at the minute.

The work being proposed is a result of the M11/N11 Needs Study which is effectively a policy document now. The M50 was outside the scope of this document.

Who has been appointed Marno do do Phase 1?

marno21 wrote: »

Upgrade of the N11/M11 is being implemented as per the N11/M11 Corridor Needs Study published in 2017:

1. Construction of one way parallel access roads north of J8 Kilmacanogue. No land acquistion required and sorts out issue of direct access in the short term
2. Widening the M11 between J4 and J6 using land in median, and upgrading J6 with increased roundabout capacity and realigned slip roads.
3. Upgrade of the N11 from J6 to J8 to 3 lanes in either direction, service roads between J6 and J7, inclusive of the closure of J6a, a major upgrade of J7 and several link roads for increased network resilience.
4. Upgrade of the N11 between J8 and J14 including dealing with direct accesses where possible.

Phase 1 has been approved for implementation as a safety scheme in the short term. Phases 2-4 are being appraised as a large scheme for potential inclusion in the National Development Plan 2018-2027.

Was a tender issued at all? Can't find one after looking there.

Kildare RDO were to appoint consultants for the initial stages before Christmas but I haven't heard anything since.

What is RDO? How come it would be Kildare and not Wicklow?

I saw a drawing showing the exit from the petrol station being to the left of the shop building onto a new (CPO'ed) lane to here

Roads Design Office I would imagine ....

L1011

Only a subset of counties have an RDO. Kildare have designed schemes well outside county boundaries before and seem to specialise in motorways - the county has no single carriageway national primaries left which does give some justification there.

marno21

Kildare RDO (Roads Design Office - for national road designs) are also in charge of the big ticket N81 scheme so seem to be taking care of Wicklow's upgrades.

it makes sense to send traffic back to the N11 via the J8 roundabout, but there's a lot of buildings, gardens etc in between.

Very true, as it is, if the traffic is heavy I'd often go up to roundabout and join the far side of bridge.

so similar to the Lucan N4 exit

A significant factor in contributing to traffic jams on this route near the Bray North exit is the 'shock wave' affect of the sudden speed drop from 120kph to 60kph just after Bray South.

There is so much wrong with that.

a) its not true. What causes most of the problems is the capacity south of Bray north, the disimprovement of the alignment and the weaving section.
b) It reduces from 100kph to 60kph just after Bray South.

Alun

It'll be interesting to see the detailed drawings when they're made public. Personally I can't see how they're going to squeeze an extra lane plus potentially a cycle track as well into the space available.

decky1

has anyone taken time to let those guy+girls that were up in the trees know about this, they may have to get back there on the double. there may be trees involved in this.

I'm assuming that the new lane will be built east of the existing petrol stations and businesses, would this be correct?

I don't think so, my understanding is that it will be similar set up to out bound on the n4 near Lucan.

There were plans at one stage for a road running parallel to n11 joining the woodies roundabout to the copeswood aviary roundabout but it met opposition from locals.

Also a problem is the merging, people on the M11 cake it when others force merge, break hard, next car has to, and so on, ultimately sometimes bringing traffic to a standstill further up the M50

Any update on this?

Consultants to be appointed for Phases 1-4 (feasibility, option selection, design and statutory process) with tender for that to be released shortly

At the end of phase 4, does that mean a route design would be released publicly, or that only happens later after detailed route selection/design? Is there a rough timeline for these phases?:)

Chris_5339762

I've heard rumours that this scheme will go all the way to Coynes Cross, ie: completely close the N11 gap. Is that true?
