Executive Summary

Transport Infrastructure Ireland in partnership with Cork County Council and Cork City Council proposes to

deliver the upgrade of the Dunkettle Interchange to a free flowing interchange. Following the publication of

statutory documents in July 2012, An Bord Pleanála approved the scheme on 23 April 2013, but included in the

approval a condition to remove the proposed path from the Dunkettle Roundabout to Dunkettle Road due to

“concerns regarding this proposed cycle route from the perspectives of potential for conflicts/accidents and

inefficiencies in traffic flow”.

This Part 8 Planning Report proposes an alternative pedestrian and cycle facility to provide the east-west

connectivity for pedestrians and cyclists through the Dunkettle Interchange.

The proposed developed comprises approximately 900m of Shared Use Cycle and Pedestrian Facilities

extending from Dunkettle Roundabout in the townland of Lota, Co Cork to terminate at cul-de-sac on Dunkettle

Road in the townland of Dunkettle. The existing cul-de-sac will be reconfigured as a shared surface street and

will bring pedestrians and cyclists to Dunkettle Road.

The proposed Shared Use Cycle and Pedestrian facility is predominantly off-road but follows the alignment of

the interchange link from N8 eastbound to M8 northbound. The initial section which crosses the Glashaboy

River is adjacent to the N8, but is physically segregated both horizontally through a 1.5m separation strip and

vertically through a kerbed upstand. The width of the proposed facility is 4m with the exception of the initial

section crossing the Glashaboy River which is constrained to 1.75m to fit within the existing structure.

Written submissions or observations with respect to the proposed development may be made in writing to the

Cork National Roads Office.

1. Introduction

1.1 Background

Transport Infrastructure Ireland in partnership with Cork County Council and Cork City Council proposes to

deliver the upgrade of the Dunkettle Interchange to a free flowing interchange, i.e. an interchange whereby

traffic movements aren’t conflicted by opposing traffic movements either by yielding or stopping at traffic signals,

as is the case with the existing interchange.

The scheme specific need relates to the current operational deficiencies associated with the existing

interchange. Although the existing interchange is of major importance in the context of the national road

network, it is currently operating above capacity in peak traffic conditions resulting in significant congestion, with

queues developing on many of the approaches. These queues result in increased journey times through the

interchange resulting in increased cost to businesses which is impacting on the economic competitiveness of

the region.

The scheme objectives are driven by the need to improve the current operational deficiencies associated with

the existing interchange. In addition to the core objectives associated with addressing the existing operational

issues, the scheme objectives also includes the minimisation of environmental impacts and consideration of

sustainable transport modes including pedestrian and cyclist facilities.

The proposed upgrade included the provision of pedestrian and cyclist facilities connecting Glounthaune to

Glanmire in an east to west and vice versa, direction and connecting Little Island and Glounthaune in a north to

south and vice versa direction. The proposed upgrade therefore caters for all movements in all directions

through the junction.

Following the publication of statutory documents in July 2012, An Bord Pleanála (ABP) conditionally approved

the scheme on 23 April 2013.

The ABP conditions included:

“3. The proposed cycle path from the Dunkettle Roundabout extending along link T1 shall be omitted

in its entirety.

Reason: The Board has concerns regarding this proposed cycle route from the perspectives of

potential for conflicts/accidents and inefficiencies in traffic flow. The Board considered that there may

be preferable cycle routes available to cater for those travelling from Dunkettle Roundabout to Little

Island such as across the tunnel to the East following a route which avoids the busiest junctions and

roads and which might be pursued by the National Roads Authority.”

The proposed cycle path to be omitted as part of the planning approval, commences at the Dunkettle

Roundabout and ran adjacent to the N8, on the northern side of the existing carriageway. The facility continued

along the proposed slip road to Glounthaune, before pedestrians and cyclists have to cross the M8 merge slip

(to avoid the diverge associated with the same link) onto the southern side of the slip road to Glounthaune,

where the facility continue towards Glounthaune. This part of the facility runs as far as the proposed roundabout

with Dunkettle Road and allowed pedestrians or cyclists to either gain access to Dunkettle Road, or alternatively

to the existing Burys Bridge Roundabout, where pedestrians or cyclists can travel east towards Carrigtwohill

and Midleton or go south towards Little Island.

This Part 8 Planning Report proposes an alternative pedestrian and cycle facility to provide the east-west

connectivity for non-motorised users through the Dunkettle Interchange.

1.2 Part 8 Planning Requirements

In accordance with the requirements of the Planning and Development Regulations, 2001 (as amended), this

report details the proposed development together with the accompanying drawings which together describe the

nature of the proposed development.

1.3 Proposed Development

The proposed developed comprises approximately 900m of Shared Use Cycle and Pedestrian Facilities

extending from Dunkettle Roundabout in the townland of Lota, Co Cork to terminate at cul-de-sac on Dunkettle

Road in the townland of Dunkettle. In addition, the existing cul-de-sac on Dunkettle Road shall be reconfigured

as a Shared Surface Street.

The location and extent of the proposed development is shown on Drawing 32107200/CYC/P8/001 and

Drawing 32107200/CYC/P8/002 respectively accompanying this report.

The proposed Shared Use Cycle and Pedestrian facility s shown on Drawing 32107200/CYC/P8/003 and is

predominantly off-road but follows the alignment of the diverge interchange link from N8 eastbound to M8

northbound. The initial section which crosses the Glashaboy River is adjacent to the N8, but is physically

segregated both horizontally through a 1.5m separation strip and vertically through a kerbed upstand.

The proposed development can be constructed within the boundary of the land acquired for the Dunkettle

Interchange Upgrade Scheme, the existing road bed of the cul-de-sac and no additional land is required.

3. Planning and Policy Context

3.1 Dunkettle Upgrade Scheme

The planning and policy context for the Dunkettle Interchange Upgrade scheme against national, regional and

local policy was established in the EIS published in 2012.

The proposed development was consistent and compatible with the following national, regional and local policy

documents at the time of publication:

National Spatial Strategy for Ireland, 2002 – 2020;

Infrastructure and Capital Investment 2012-16: Medium Term Exchequer Framework;

Smarter Travel, 2009;

Cork Area Strategic Plan 2001 (and update of 2008);

Cork County Development Plan, 2009;

Blarney Local Area Plan, 2011;

Cork City Development Plan, 2009 – 2015; and

South West Regional Authority Regional Planning Guidelines 2010 – 2022.

3.2 Proposed Development Planning and Policy Context

The planning and policy context for the proposed development is set by Dunkettle Interchange Upgrade

Scheme. However, the sections below provide additional context for the proposed shared use pedestrian and

cycling facility with respect to various plans and policies including:

The EuroVelo International Cycle Network;

The Government’s Smarter Travel initiative;

The National Cycle Policy Framework;

The Regional Planning Guidelines;

The Development Plans of the respective affected Local Authorities; and

Cork Cycle Network Plan

3.2.1 The EuroVelo International Cycle Network

The European Cyclists’ Federation is coordinating the development of a network of high-quality cycling routes

that connects Europe and can be used by both long-distance cycle tourists, as well as by local people making

daily journeys. The EuroVelo network currently comprises of 15 routes and it is envisaged that the network will

be substantially complete by 2020.

EuroVelo Route EV1 (Atlantic Coast Route) extends from Norway to Portugal along the west coast of Europe in

Ireland, this route extends from Larne, County Antrim in the northeast, around the northern, western and

southern coasts, via Kerry, Cork and Waterford and ending in Rosslare, County Wexford in the southeast.

The Cork Cycle Network Plan (Refer to Section 3.2.5) has included for connections from the east with an inter-

urban route via Midleton and Carrigtwohill to respond to the strategic intent of the Eurovelo route network.


32107200/P8/CYC/001 6

3.2.2 Smarter Travel: A Sustainable Transport Future 2009 – 2020

Smarter Travel: A Sustainable Transport Future is defined as the transport policy for Ireland for the period 2009-

2020. The policy recognises the vital importance of continued investment in transport to ensure an efficient

economy and continued social development, but it also sets out the necessary steps to ensure that people

choose more sustainable transport modes such as walking, cycling and public transport.

The policy aims to achieve sustainable transport through a suite of actions that will have complementary

impacts in terms of travel demand and emissions. This includes actions aimed at ensuring that alternatives to

the car are more widely available including investment in cycling and walking.

3.2.3 National Cycle Policy Framework

The National Cycle Policy Framework (NCPF) 2009-2020 operates under the overarching Smarter Travel policy

but focuses specifically on cycling. The mission of the NCPF is to create a strong cycling culture in Ireland with

a vision that all cities, towns, villages and rural areas will be bicycle friendly and an aim that 10% of all trips will

be by bike by 2020.

The framework sets out that all planning should consider the needs of cyclists which should be articulated in all

National, Regional, Local and sub-local plans. Cycling friendly urban planning principles will cover the need to

keep distances between origin and destination short, through making developments permeable (i.e. easy for

pedestrians and cyclists to pass through without making long detours) and well connected. Transportation

infrastructural designs need to be cycling friendly meaning that routes taken by cyclists are safe, direct,

coherent, attractive and comfortable

The framework proposed a hierarchy of measures including the following measures for cycle route development

and states the focus needs to be on:

reducing volumes of through-traffic, especially HGVs, in city and town centres and especially in the

vicinity of schools and colleges;

calming traffic / enforcing low traffic speeds in urban areas; and

making junctions safe for cyclists and removing the cyclist-unfriendly multi-lane one-way street

systems

3.2.4 Cork County Development plan 2013-2019

The Cork County Development plan 2013-2019 sets out an overall strategy for the proper planning and

sustainable development of Cork County over a 6 year period. The Development Plan vision and main aims for

the County is underpinned by the core principles of sustainability, social inclusion, quality of design and climate

change adaptation.

A key aim of the plan includes:

a) Enhanced quality of life for all, based on high quality residential, working and recreational

environments and sustainable transportation patterns;

The plan sets out a number of policies and objectives related to transport and in particular walking and cycling:

TO 7-1:Walking/Cycling and Greenways: Promote the development of walking and cycling routes

throughout the County as an activity for both international visitors and local tourists in a manner that is

compatible with nature conservation and other environmental policies.

TM 1-1: Transport Strategy:

- a) Provide a choice of transport modes for all citizens and visitors. Foster sustainable economic

and population growth by maintaining and developing an efficient and integrated transport system

for the County and, at the same time, encourage balanced investment in less polluting and more

energy efficient modes of public and private transport.


32107200/P8/CYC/001 7

TM 2-1: Walking

- a) Encourage and facilitate a safe walking route network and a culture of walking where possible

and practical.

TM 2-2: Cycling

- a) Encourage and facilitate a safe walking and cycling route network and a culture of walking and

particularly cycling in the county, as a viable alternative travel choice. Local Area Plans will set

out Active Travel Strategies (cycling and walking) for individual towns and their hinterlands.

- d) Promote the development of an integrated and coherent local and countywide cycle network to

form part of the wider National Cycle Network. Routes will be promoted which generally seek to

avoid or minimise impacts on the environment and on EU designated sites.

TM 3-1: National Road Network: Seek the support of the National Roads Authority in the

implementation of the following major projects:

Projects Critical to the Delivery of Planned Development:

N28 (Cork – Ringaskiddy).

M8 (Dunkettle Interchange Upgrade).

Cork Northern Ring Road (N22/N20/M8)

Key NSS Projects

M 20 (Blarney – Mallow – Limerick).

N 25 (Carrigtwohill – Midleton – Youghal).

The plan recognises that a number of strategies, studies and other projects have already been developed or are

underway in the County which seek to put cycling to the forefront including in the County Metropolitan Area the

County, a cycle strategy that identifies both strategic and future local cycle links both within and from the

Metropolitan Towns.

3.2.5 Cork Cycle Network Plan

Cork City Council and Cork County Council prepared a Cycling Network Plan for the Cork City Metropolitan

Area and surrounding towns. The objective of the plan is to provide a clear plan for the future development of

the cycling network within the Metropolitan Area to encourage greater use of cycling for trips to work, school,

recreation and leisure.

The network has been categorised into different categories including:

Urban Cycle Network

- Primary: Main cycle arteries that cross the urban area and carry most cycle traffic

- Secondary: Link between principal cycle routes and zones

- Feeder: Cycle routes within local zones and/or connections from zones to the network levels

above (primary and secondary)

Inter-Urban Cycle Network: Links the towns and city across rural areas and includes elements of the

National Cycle Network

Green Network: Cycle routes developed predominantly for tourist, recreational and leisure purposes

but may also carry elements of the utility cycle route network above

The Plan sets proposals for the cycle network with Cork City and the metropolitan towns and includes corridors

to connect the Metropolitan Towns to Cork City and also to connect the suburban areas to Cork City Centre.


32107200/P8/CYC/001 8

This includes key inter-urban routes (IU-1) which comprises:

Segregated cycle path from Midleton to Dunkettle Roundabout via Carrigtwohill, Little Island and the

Dunkettle Interchange where it can collect trips from Glanmire.

The proposed development is located in the Glanmire, Glounthaune and Little Island metropolitan network. The

plan highlights that lack of facilitates in the area and in particular Little Island which has no dedicated cycling

facilities going to or from the Island and is accessed via the Dunkettle interchange, the N25 junction slip roads

or via an overbridge which connects it with the Old Dublin Road north of the N25.

The following networks are proposed in the vicinity of the proposed development and the Dunkettle Interchange

Upgrade Scheme.

Interurban

- IU-1: Parallel to Midleton Rail Corridor and Old N25 (Midleton to Dunkettle Roundabout/Lower

Glanmire Road)

Primary

- CCN-U26: Lower Glanmire Road (Dunkettle Roundabout to Pemrose Quay)

- GL-U1: Glanmire Road (Dunkettle Roundabout to Lower Glanmire)

- GL-U3 Dunkettle Road (East Cliff Road to N25)

- LI-U2 R623 Eastgate Entrance to St. Lappans Church/Island Cross

- LI-U6 To R623 (Future Link to Dunkettle Interchange)

Potential Primary

- LI-U10: Little Island to Lower Glanmire Road (From Dunkettle Interchange Link to Dunkettle

Roundabout via waterfront)

Secondary

- LI-U9: Factory Hill (Dunkettle Road to Old N25)

The proposed development is consistent with part of the route of the proposed IU-1 Parallel to Midleton Rail

Corridor and Old N25 Inter-urban corridor for the section between Dunkettle Roundabout and Dunkettle Road.

The plan proposes that the infrastructure should be fully segregated cycle track (physically segregated from

motorised traffic) running parallel to the rail line from Midleton to the west of Carrigtwohill village where it is

proposed to provide a two way segregated cycle track within the corridor of the old N25. The plan proposes that

this route can form part of the Eurovelo Network between Waterford and Kerry, connecting to the west through

the proposed network in the City Centre.

The proposed development, as part of the proposed IU-1 directly links with the proposed networks CCN-U26,

GL-U1, and GL-U3. In addition, the other north-south cycling facilities provided as part of the Dunkettle

Interchange form network LI-U6 and link to LI-U9, LI-U2, LI-U10 and connect back to IU-1.

The proposed development in the context of the Dunkettle Interchange Upgrade Scheme and the Cork Cycle

Network Plan is shown on Drawing 32107200/CYC/P8/002.

km/h should be implemented.


32107200/P8/CYC/001 10

4.4 Route Description

The proposed development is shown on Drawing 32107200/CYC/P8/003 accompanying this report.

The proposed facility commences at the Dunkettle Roundabout. The roundabout will be signalised as part of

the Dunkettle Upgrade Scheme and includes crossings for pedestrians and cyclists but does not form part of

this Part 8 Planning submission.

The facility heads eastbound to cross the Glashaboy River. A new kerb line will be constructed across the

structure to create a raised verge on which the segregated facility will run. The 1.75m wide shared facility will

be separated from the carriageway horizontally by a 1.5m wide separation strip and vertically by the kerb. A

0.25m horizontal clearance will be provided between the facility and the parapet which will be replaced with a

new 1.4m high parapet.

Figure 4.1 : Cross-Section across Glashaboy River Bridge

Having crossed the river, the facility will widen to its full 4m width with a 1.5m separation zone maintained to the

carriageway. The cycleway crosses a private residential access before diverging from the N8 carriageway

approximately 200m from the start of the facility. The cross-section of the facility comprises a 4m shared cycle

track with 0.5m grass verges on each side. The facility is physically separated from the carriageway by a large

horizontal distance and vertically by a difference in elevation between the road and the shared facility. In

addition, a boundary fence is provided at the back of the shared facility verge.

Figure 4.2 : Cross-Section of facility remote from the road


32107200/P8/CYC/001 11

The route of facility continues eastwards following the line of the road boundary from approximately 400m

before heading north following the line of road boundary of the M8. The shared facility is segregated from the

M8 motorway through a horizontal separation zone in addition to a 2.4m high security fence positioned at the

back of the verge of the shared facility. To minimise vegetation loss at the northern end of the facility the width

of the shared surface will reduce to 3m at the 800m mark and continue to the end of the new facility where it ties

in with the cul-de-sac. The overall length of the new facility is 913m.

The proposed off road cycletrack terminates at a cul-de-sac on Dunkettle Road where it will continue as a

shared surface street. The shared surface will be retrofitted over the length of the cul-de-sac where it ties in with

future primary network GL-U6 as highlighted in the Cork Cycle Network Plan 2015.

The Propose Shared Street will be finished with a contrasting surfacing to indicate that the carriageway is an

extension of the pedestrian domain. The shared street shall have a maximum carriageway width of 4.8m which

will be demarcated with flush kerbs fully embedded within the surface of the street. The remaining width

between the existing walls shall act as refuge zones allowing pedestrians to step on and off the carriageway to

let cars pass.

4.5 Gradient

The elevation of the route rises from 4 mOD east of the Glashaboy River to approximately 22 mOD at the tie-in

at the Dunkettle Road cul-de-sac at an average gradient of 2.2%. The gradient follows the natural topography

and increases towards the tie-in to the Dunkettle Road cul-de-sac with a section of 4.4% gradient for

approximately 165m to the tie-in with the shared surface street.

4.6 Pavement

Construction of the shared facility shall consist of bound flexible pavement with the exception of the length of

the Glashaboy River Structure which shall be concrete. The shared surface street shall be in accordance with

the Design Manual for Urban Roads and Streets. The exact specification and design of the pavement shall be

determined in the detailed design.

4.7 Vehicular Access

The route crosses a single private residential access. The crossing facility shall; be a bend out crossing in

accordance with TII Publications DN-GEO-03060 Geometric Design of Junctions.

The bend out junction treatment includes a straight approach for cyclists to ensure that cyclists are provided

with full visibility on entry to the junction treatment. The horizontal radii of 10 metres on the cycle facility shall be

introduced to encourage lower cycle speeds on approach to the junction. A colour contrast treatment shall be

provided along the cycle route warning cyclists of the upcoming conflict with motorised traffic.

4.8 Drainage

The cycle facility shall be constructed with a crossfall generally between 1.0% and 3.0%, with a maximum of

5.0% permitted over short sections. Surface water runoff from the cycletrack will be collected by direct runoff

into combined surface water and ground water filter drains.

4.9 Public Lighting

The new section will be fully lit.


32107200/P8/CYC/001 12

4.10 Signage and Road Markings

At the start and end of a cycle facility and where the cycle facility connects with a public road, Sign RUS 058

(Traffic Signs Manual) for facilities shared between pedestrians and cyclists will be erected.

Figure 4.3 : RUS 058 Sign

In addition, road markings will be provided on Dunkettle Road in advance of the junction with the shared surface

street to warn of the presence of cyclists.

4.11 Boundary Fencing

Permanent road side boundary fencing will be erected as part of the Dunkettle Interchange Upgrade Scheme at

the extent of the land purchased for the scheme. In addition, boundary fencing will be erected at the back of the

right hand verge of the cycle facility in the off-road section between chainage 200m and chainage 900m. The

fencing shall be timber post and tensioned mesh with the exception of the section adjacent to the M8 motorway

between chainage 670m and 900m which shall be 2.4m high palisade fencing for security purposes.

An AA Screening for the Dunkettle Interchange Upgrade Scheme was undertaken by Scott Cawley on behalf of

Jacobs in 2011 and concluded that an Appropriate Assessment (AA) would be required for the scheme. The

Appropriate Assessment was undertaken and a Natura Impact Statement (NIS) published in 2012. As a result of

the appropriate design of the Dunkettle Upgrade and proposed mitigation measures, the NIS concluded that the

proposed development will have not result in impacts on the integrity of any European Sites.

The NIS can be downloaded from the Dunkettle Interchange Upgrade Scheme website:


5.2 Environmental Impact Statement

The Environmental Impact Statement for the Dunkettle Scheme was published in 2012 including a schedule of

environmental commitments. The purpose of these environmental commitments is to mitigate or ameliorate

potentially significant adverse impacts that have been identified in the EIS.

This is included Specific Landscape Measures (SLM01) to the boundary of Dunkettle House comprising the

retention and protection of the existing vegetation to Dunkettle House boundary to maximum extent feasible.

Upon completion of new earthworks and road alignment plant low canopy woodland with high percentage of

evergreen species (EW1) to embankments. This mitigation will also be implemented for the construction of the

shared facility.
