Dublin Airport has secured a 2.4m wide new runway, the first new runway in the country since the introduction of the 2.8m wide runway at its current height.
Airport Minister Michael Creedon said the new runway would be operational in 2020 and will be a “significant asset for the city”.
He said the airport will become the largest new airport in Ireland and is one of a number of airports across the country to have received this type of upgrade.
“It is significant that Dublin Airport is on track to become one of the most globally connected airports in the world,” he said.
“Our new runway will provide a much wider and more integrated hub and terminal than ever before.”
He said there was “more than one billion passengers in Dublin” and said there were plans to invest in new passenger and baggage facilities and “build a new terminal in the centre of the city to replace the ageing Terminal 4”.
The airport’s new runway has been the subject of a lengthy, contentious debate among residents and local residents, with many of the objections coming from the Dáil’s own elected representatives.
Mr Creedon’s decision to expand the airport’s runway comes just days after the Dílí Mac Ó Catháin government announced it was extending its airport runway for the second time, after two other expansions.
The second extension will see a new 6m wide airport runway at the airport, with a 3m wide extension of the runway already under construction.
The new runway is expected to open by the end of 2020.
The Dublin Airport Authority said it had secured a new runway of 2.9m wide.
A second runway at Dublin Airport was previously awarded to US based Boeing Co and was scheduled to open in 2017.
The agency said a new, smaller runway was being planned at the Dublin Airport but had not yet been awarded.
Dublin Airport is Ireland’s busiest airport and has about 11 million passengers a year.
Mr Creagh said it was a great achievement for the Irish Government that it was the first airport to receive this type, adding that it represented “a major step forward” in the development of the airport.
“This is a significant investment that will bring benefits to the city of Dublin and the wider community,” he added.
Airports in the US and the UK also received 2.6m and 2.7m wide extensions of their runway respectively in 2016.
