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 alternatives and options to address the transport problems identified during Phase 1 and to carry out a systematic assessment of these with a view to selecting a preferred transport solution which will form the basis for the detailed design. To date, the study area has been identified  and the key constraints were displayed as part of Public Consultation No. 1. A link to the consultation material is available here.

Following the conclusion of Public Consultation No. 1 on constraints, the design team identified feasible Alternatives (i.e. active travel, improved public transport and demand management measures) and Option Corridors (i.e. road based options). These feasible Alternatives and Options Corridors were displayed as part of Public Consultation No. 2. A link to the consultation material is available here.

The purpose of this non-statutory consultation was to inform the public and stakeholders of the results of the comprehensive constraints study and the various transport solutions under consideration and the programme for advancement of the project. Public consultation forms an important part of advancing the design process towards the selection of a preferred transport solution and allows the involvement of the public in this process.

The next step in the Option Selection process will be the assessment of feedback and submissions received by the Project Team and undertaking the Stage 2 assessment of the Option Selection process using a multicriteria analysis under the headings of Safety, Economy, Environment, Accessibility and Social Inclusion, Integration and Physical Activity. This is to determine the best performing Alternative or Option or combination of Alternative(s) and/or Options to be taken forward as the Preferred Transport Solution. It is envisaged that a public display of the Preferred Solution will take place in Q2 2022.
