I received the following from the Dublin Airport Authority –
Runway Maintenance Notice
Dublin Airport’s main runway is to close at night for a period of two weeks for essential maintenance.
The work is due to begin on Monday September 23 and will continue each night between 11.30pm and 4.30am until Sunday morning, October 6. No work will take place on Sunday nights.
This work forms part of the upkeep and maintenance of the runway system at Dublin Airport and is critical for the safe operation of the airport. For operational reasons, this essential maintenance, which is weather dependent, can only be carried out at night.
During this maintenance work, aircraft using Dublin Airport will land and take off on the north/east south/west runway known as R16/34 or the crosswind runway.
Dublin Airport regrets any inconvenience that may be caused by these essential runway works.
