The project is expected to create 150 construction jobs as the runway receives its first full overhaul in 27 years.
The gateway claims that the revamp, which includes a complete resurfacing and the installation of new ground lighting systems, is essential to ensure that its main runway can continue to operate safely.
Runway 10/28, which opened in 1989, typically handles 95% of all flights at Dublin Airport and is a critical element of Ireland’s infrastructure.
The work is required to ensure that the main runway continues to meet the strict regulations governing the operation and specification of runways at major airports.
Construction work will take place overnight between 11pm and 5am for the next 18 months, and can only happen overnight as it requires the full closure of Dublin Airport’s main runway.
“This is an essential investment in the future of Dublin Airport and in the future of the Irish economy,” says Dublin Airport's managing director, Vincent Harrison.
“Our main runway has been the workhorse of Dublin Airport since 1989 and has allowed the airport to grow from five million passengers per year to a record 25 million passengers last year.
“More than four million aircraft have taken off or landed on our main runway during the past 27 years and it’s now in need of a substantial overhaul.”
While the night-time construction works are ongoing, flights will use Dublin Airport’s secondary runway, which is also known as the crosswind runway.
Runway 16/34 has been the airport’s secondary runway since 1989 and typically handles about 5% of total traffic at the airport.
The work, which is weather dependent, is due to take place every weeknight for the next 18 months.
It will involve a full resurfacing of Runway 10/28, which is 2,637m long, with three new layers of asphalt. The project also includes replacing the ground lighting system for the runway with new LED lights, which will reduce energy consumption by about 66%.
Last year Dublin Airport had almost 198,000 landings and take-offs, with 95% of aircraft using the airport’s main runway.
