The Public Consultation on ‘Constraints’ concluded 17 February 2021 and the Virtual Consultation Room is no longer available. All the information that was presented at the consultation is available here.


Tipperary County Council, in partnership with Limerick City and County Council, Transport Infrastructure Ireland (TII) and the Department of Transport are developing the N24 Cahir to Limerick Junction Project. Tipperary County Council, as lead authority, has appointed Arup as Technical Advisors to progress the Planning and Design for the Project through Phases 1 to 4 of the TII Project Management Guidelines (PMG) as outlined below:

  • Phase 1 (Concept and Feasibility)
  • Phase 2 (Option Selection)
  • Phase 3 (Design and Environmental Evaluation)
  • Phase 4 (Statutory Processes)

The project is currently at Phase 2 Option Selection. The interactive webmap can be viewed here.

Project Background

The N24 national primary route, is a strategic corridor from Limerick to Waterford, traversing through County Tipperary and is approximately 116km in length. It is recognised as being of particular importance in enhancing accessibility to towns it passes through, namely Tipperary Town, Cahir, Carrick-on-Suir and Clonmel, and their rural hinterland.

The section of the existing N24 under consideration in this Project, the N24 Cahir to Limerick Junction Project, is between the M8 motorway, north of Cahir in Co. Tipperary and an appropriate tie-in point in County Limerick and traverses Tipperary Town and the villages of Bansha, Limerick Junction, Monard and Oola.

Existing Conditions

Initial studies for this project have identified that the existing road has restricted capacity due to its limited width, partially sub‐standard alignment and its passage through four villages and Tipperary Town. When considered in association with the very high level of junctions and private accesses on the existing route, this contributes to limited overtaking opportunities and unstable traffic flow regimes along the existing route. The existing route currently experiences bottlenecks and significant traffic delays through Tipperary Town. It is considered that the existing road is economically inefficient and detracts from the development and growth of the region.

Key Objectives

The key objectives of this project are to improve safety, journey reliability and the strategic function of this section of the N24 corridor. In achieving these objectives, the project will in turn:

  • Encourage local, regional, national and international development by:
    • Improving journey time and journey time reliability
    • Provide opportunities for the economic development of Tipperary Town and other communities along the corridor
    • Improve connectivity between the cities of Waterford and Limerick
  • Reduce social exclusion by enhancing accessibility to services from designated rural zones within the study area thus reducing disadvantage in these areas.
  • Support health benefits derived from potential active modes by enabling opportunities for creating a safer environment for walking and cycling within the project extents.
  • Reduce the potential for collisions through provision of a safer travel option for all users.

What’s Happening Now

The project is currently at Phase 2 Option Selection. The purpose of this phase is to examine feasible alternative options to address the transport problems identified during Phase 1 and to determine a Preferred Option for the project. Whilst the need for a project is influenced by Government Policy and all current planning policy, it is also necessary to define the existing problems using quantifiable performance indicators i.e. evidence-based analysis of the transport issues.   All forms of transport and/or other non-road options will be examined as possible alternatives during this phase of the project.

The first non-statutory public consultation on ‘Constraints’ took place between 27 January 2021 to 17 February 2021 and is now complete. The purpose of this consultation was to inform the public of the study area for the project, the key constraints identified to date and the programme for advancement of the project. Public consultation forms an important part of advancing the design process towards the development of transport options and allows the involvement of the public in identifying key constraints. The development of transportation solutions, which could include multiple route corridors is currently underway. It is expected to have potential options identified in late Q2 2021.
