N4 Mullingar to Longford (Roosky)

N4 Mullingar to Longford (Roosky) Road Improvement Scheme

PHASE 3 - PUBLIC INFORMATION EVENT

Westmeath County Council in conjunction with Longford County Council, supported by Transport Infrastructure Ireland (TII), invite all stakeholders, landowners, members of the public and interested parties to participate in a Public Information Event for the N4 Mullingar to Longford (Roosky) project.

This 52km section of the N4 is a single carriageway road that passes through or close to several settlements, including Ballinalack, Rathowen, Edgeworthstown, Longford and Newtown Forbes. This section accounts for approximately 25% of the entire N4/M4 corridor and is the largest unimproved section of this route.

The road services upwards of 23,500 vehicles per day and features more than 500 junctions and direct accesses. This section of the N4 continues to see high collision statistics, with over 215 personal injury collisions reported between 2008 and 2024. Of these collisions, 20 resulted in fatalities and 41 resulted in serious injuries. The project aims to address the road safety issues along the corridor, allowing for safer and more reliable journeys for all road users, including vulnerable users and users of road-based public transport.

The Project Team are working to improve safety and connectivity between Mullingar, Longford and onwards to Roosky. By resolving the network deficiencies along this section of the N4, the project will enhance the overall accessibility in the region and to the West/North-West.

The project will aim to reduce traffic levels within the settlements along the route and allow for reallocation of road space through the provision of dedicated walking, wheeling and cycling routes. The project will also act as an enabler for strengthening tourism through improved connectivity between Ireland’s Ancient East, Hidden Heartlands, and the Wild Atlantic Way.

The sustainability strategy for the project will support sustainable mobility options and the Climate Action Plan targets for carbon dioxide (CO₂) reductions through embedding best practice carbon management throughout the project lifecycle.

Following the selection and publication of the Preferred Option in Phase 2, the project has progressed into Phase 3 – Design and Environmental Evaluation. Since late 2025, the Project Team have been engaging with landowners to facilitate the extensive engineering and environmental surveys required to support and inform the design process. This has included extensive ground investigation, topographical surveys and various environmental surveys. The Project Team would like to thank the landowners for their ongoing engagement facilitating access.

As survey information has become available, the design has continued to evolve and has now reached a stage where further engagement has and will continue to take place. Over the past number of weeks, the Project Team have commenced holding individual meetings with directly impacted landowners across the project, to discuss progression to date and gather any feedback that may assist in refining the design further. It is envisaged that this will continue over the coming months.

The N4 transportation corridor between Mullingar and Roosky, County Longford forms part of the key Dublin to Sligo National Primary route (part of Trans-European Network for Transport). This scheme forms part of Project Ireland 2040 and is included in the National Development Plan 2021 – 2030.

A series of in-person Public Information Events will take place in Mullingar, Edgeworthstown and Longford between Monday 28th September 2026 and Wednesday 30th September 2026 to present the current design development to the public: 

Monday 28th September 2026 - 2pm to 8pm
