Dublin MetroLink is Ireland’s first infrastructure mega-programme and the largest transport investment in the nation’s history. The 18.8km metro line, featuring sixteen stations, will transform mobility across the Greater Dublin Area. With Dublin ranked as the world’s second most congested city according to Inrix, the need for a high‑capacity and sustainable transport solution is clear. MetroLink delivers exactly that: faster, greener and greater capacity, aligned with Project Ireland 2040 and the Climate Action Plan 2024.
Mace Consult brings extensive expertise in programme management, stakeholder engagement, sustainability and supply chain strategy. We are supporting Transport Infrastructure Ireland (TII) to develop carbon management and reduction processes aligned with PAS 2080, embedding low‑carbon thinking throughout the programme. Our wider work includes strategic planning, market engagement and social value initiatives that ensure long‑lasting community benefits.
MetroLink’s impact will be transformative. The scheme is expected to create 8,000+ jobs during construction, boost economic growth, and significantly improve connectivity for 175,000 residents, with direct links to 250,000 jobs across the region. It will deliver seamless intermodal connections, including a new direct route to Dublin Airport, while reducing congestion and carbon emissions.
Delivering a project of this magnitude brings complex environmental and stakeholder challenges. Through structured planning, inclusive collaboration and innovative thinking, we are helping deliver a once‑in‑a‑generation transport solution that will serve communities for decades to come.
