If Dublin's first underground rail line goes ahead in its current form it will transform local amenities into a construction site of an unprecedented scale.
That's the warning from a sports club in Glasnevin, which could lose access to some of its facilities while Metrolink is being built.
The 26 kilometre line between Swords and Sandyford is expected to take six years to complete.
Chairman of Na Fianna GAA club, Cormac O'Donnchu, is in favour of the project - just not in its current form.
"It will transform a space which has been lovingly nurtured by generations of volunteers as a remarkable culture and community centre, into a construction site of an unprecedented scale".
He warned that "a generation of children will be deprived of the chance to engage in healthy activity in their local community during their most formative years.
Cormac O'Donnchu was speaking at a meeting of The Transport Committee, which met with a number of stakeholders this afternoon to discuss the impact the construction of Metrolink could have on local amenities.
If it goes ahead in its current form, Metrolink will run for 26 kilometers between Swords and Sandyford - with construction expected to take six years to complete.
A number of schools and sports clubs have raised concerns that the works mean they will lose access to some of their facilities, and also be affected by noise, pollution and extra traffic.
Marcella Nic Niallaigh, Principal of Scoil Mobhí, told the Committee that there will be "major health concerns, due to the likelihood of dust, diesel emissions, noise and vibrations".
She explained that construction "will make effective education impossible".
