The study area associated with the proposed N5 Turlough to Bohola and Swinford to Mount Falcon Road Project commences on the existing N5 in the townland of Capparanny and terminates on the existing N5 in the townland of Clooneen, east of Bohola.   The study area also extends northwards to Mount Falcon and eastwards to Swinford and in doing so captures the existing N5, N26 & N58 road corridors and such areas as Turlough, Ballyvary, Bohola, Straide, Foxford, Callow and Swinford.

The proposed project will consider the upgrade of the existing N5 from Turlough to Bohola.   In conjunction with this it will consider the most appropriate road corridor link (N26/N58) from the existing and/or proposed N5 to Mount Falcon.   The proposed project will also consider the upgrade of the existing N26 from Foxford to Swinford.


The development of this road project has been identified in the following documents;

  • The National Spatial Strategy
  • The National Development Plan 2007 – 2013
  • Mayo County Development Plan 2008 – 2014
  • Plans and programmes of the National Roads Authority.

The need for the scheme will be set out in detail in the Design Report and the EIS.

The project is promoted by Mayo County Council (Mayo NRDO) and is in partnership with the National Roads Authority.   Mayo NRDO has appointed Roughan O’Donovan-AECOM as the consultant engineers for the project.   This project has been funded by the Irish Government under the Department of Transport, Tourism and Sport

The planning and design for N5 Turlough to Bohola Road Project Road commenced in 2012. In March 2014 the extents of the Study Area were increased to include consideration of the upgrade of the N26 from Swinford to Mount Falcon. The project is now called the N5 / N26 / N58 Turlough to Bohola and Swinford to Mount Falcon Road Project.  In 2010 the NRA published the 2010 NRA Project Management Guidelines which outlines the framework for the phased approach to the development, management and delivery of national road schemes.   The project’s development will follow this structure which divides the evolution and progression of a project into 7 phases as illustrated below;

The purpose of Phase 1 is to identify the need for a scheme and to establish a Project Management Structure including the appointment of Service Providers, where necessary.   Phase 1 can also include feasibility studies that may be carried out investigating whether a scheme is warranted/necessary.

The purpose of Phase 2 is to identify a suitable Study Area for the examination of alternative routes, to identify key constraints within that Study Area, to develop feasible route options and to carry out a systematic assessment of these options leading to the selection of a Preferred Route Corridor which will form the basis for the detailed design to follow.


The preferred route for the N5 / N26 / N58 Castlebar East to Bohola and Swinford to Mount Falcon Road Project was adopted by Mayo County Council on the 13th July 2015.

The purpose of Phase 3 is to develop the design of a scheme, following the selection of a Preferred Route Corridor, to a stage where sufficient levels of detail exist to establish land-take requirements and to progress the scheme through the statutory processes. The design may be completed to sufficient detail to identify junction types, locations, accommodation works etc. and to assist in the scoping of the environmental assessments required to develop proposals to go forward to the statutory process in Phase 4.


The purpose of Phase 4 is to prepare the relevant environmental assessments/reports/statements necessary to confirm that the proposed scheme is in accordance with planning and environmental legislative and procedural requirements.   In tandem with this, the mapping necessary for land acquisition is prepared in accordance with the statutory processes.


The purpose of Phase 5 is to prepare any Advance Works Contracts and to prepare the tender documentation, assessment of tenders and award of the Main Construction Contract.

The purpose of Phase 6 is to administer the Main Construction Contract and manage the entire Scheme during the Construction and Implementation Phase.

The purpose of Phase 7 is to complete all outstanding contractual and residual issues relating to the Scheme leading to the closeout of the entire project and on the review of the Scheme to ascertain the key lessons to be learned for future Schemes.
