Phase 3 aims to advance the design of the Preferred Option to a level of detail that defines land requirements, addresses potential impacts, and prepares the project for statutory processes.
Sligo County Council has awarded a Topographic and Hydrographic Survey Contract to Apex Surveys. These surveys will complete the remaining sections of the route (which were omitted due to the 2024 Ministerial Condition on funding), specifically from Ireland West Airport Knock to Charlestown, and from north of Tobercurry to Collooney. Surveys are expected to commence in early January 2026. Letters have issued to all registered owners of lands or property within the survey area informing them of the survey.
To support the delivery of Phases 3 (Design and Environmental Evaluation) and Phase 4 (Statutory Consent), Sligo County Council intends to engage a multi-disciplinary consultancy firm. The contract award is anticipated in 2026, subject to TII approval and funding.
We are committed to keeping landowners informed throughout this stage of the project. Members of the project team will engage directly with affected and potentially affected landowners as information becomes available, ensuring that queries are addressed promptly and that all stakeholders have a clear understanding of how the project may interact with their property.
We appreciate the community’s continued cooperation and patience as we work together to deliver this vital infrastructure, which will enhance connectivity and support economic growth across the northwest.
