Ireland’s landmark MetroLink programme has cleared a major hurdle after Cabinet approved the transition to the detailed tender stage, paving the way for market bids to be sought and delivery partners selected for the scheme’s construction and operation.
The decision marks one of the most significant milestones in the project's development to date and signals the Government’s intention to move rapidly towards construction. Early enabling works are expected to begin from early next year, with major tunnelling operations and station construction following thereafter.
When delivered, MetroLink will become the largest infrastructure project undertaken in Ireland since the construction of the Ardnacrusha hydroelectric power station in the 1920s. The fully electric, driverless and predominantly underground railway will be the first system of its kind on the island of Ireland and is set to transform public transport connectivity across Dublin and the wider region.
The 19km metro line will link Estuary and Swords in north Dublin with Charlemont in the city centre, serving key destinations including Dublin Airport, Dublin City University, Ballymun, Glasnevin and major healthcare facilities including the Mater and Rotunda hospitals.
The project is also designed to integrate seamlessly with Ireland’s wider transport network, providing connections with DART, heavy rail, Luas, regional bus services and the M1 motorway.
Taoiseach Micheál Martin welcomed the Government’s decision, stating:
“Today’s approval reflects the Government’s commitment to investing in new infrastructure.”
“MetroLink will help make our capital city a better, more sustainable place in which to live, travel, socialise and work. I am delighted that the Government has moved MetroLink into the detailed procurement phase for multi-billion-euro construction and operation contracts, and we will continue to support it into construction.”
Tánaiste Simon Harris highlighted the wider social and economic benefits of the scheme:
“Today’s decision is an important milestone in the delivery of a major public transport project that will connect our capital city to national transport networks and strengthen our economy as well as our competitiveness as a country.
"By providing a fast, frequent, and reliable public transport service, MetroLink will improve access to education and health facilities, to jobs, and to sports clubs, parks, and playgrounds. Projects like this are central to building the country our growing population now requires by helping to connect communities and unlock new housing."
Minister for Transport Darragh O’Brien described MetroLink as a transformative investment with significant housing and environmental benefits.
“I welcome today’s important step forward for MetroLink, a vital transport project that will help reduce traffic congestion, improve access to Dublin Airport and unlock much-needed new housing development at scale.
“MetroLink will support the delivery of approximately 77,000 new homes along its route and, through its integration with other public transport services, up to 200,000 new homes across the Greater Dublin Area.
“This is a game-changer for Dublin and the wider region as we work to deliver more homes for a growing population. MetroLink will not only transform connectivity and access but also strengthen our economic competitiveness, support sustainable growth and unlock the development potential of communities across the Greater Dublin Area.
“MetroLink also supports decarbonisation by providing a reliable, low-carbon alternative to private car travel, helping to reduce road traffic, transport-related emissions and overall carbon footprints across the region.”
The Cabinet decision follows a joint review by the Department of Transport and the National Transport Authority of the project’s Detailed Business Case under Approval Gate 2 of Ireland’s Infrastructure Guidelines.
Current estimates place the overall project cost between €14.44 billion and €17.49 billion, including inflation and contingency allowances but excluding VAT. The central estimate stands at €15.75 billion. Government assessments indicate that the long-term economic and societal benefits of the scheme outweigh the anticipated costs, with benefits including reduced congestion, faster journey times, improved accessibility and enhanced regional connectivity.
However, more precise construction costs will not be confirmed until detailed market bids are received during the next procurement phase.
Minister of State at the Department of Transport Seán Canney emphasised the project's strategic importance across the broader transport network:
“This approval is a positive decision for our whole transport portfolio. Interchanges at Glasnevin and Tara Street, along with the Park and Ride at Estuary, will make MetroLink and its range of destinations easily accessible to passengers transferring from heavy rail services or cars. The decision is also a strong indication to the market that this Government is serious about transforming our plans into reality, which will have a positive impact on the rest of our ambitious portfolio of transport projects.”
