The Department of Transport has been advised by Donegal County Council that works will begin on the construction of a breakwater outside the entrance of Greencastle Harbour on Lough Foyle in Co Donegal.

These works will begin on Monday 12 June and are anticipated to continue until December 2023, subject to weather and operational constraints.

The works include, but are not limited to, the following main construction elements:

  • Construction of a 150m extension to the existing breakwater
  • Construction of temporary works to include access roads, storage, temporary quay and weigh bridge at Queensport in Greencastle
  • Removal of existing Aids to Navigation (AtoN) and installation of new temporary AtoN’s
  • Importation of circa 350,000 tonnes of rock core and rock armour by land and also by sea from Foyle Port
  • Placement of circa 350,000 tonnes of rock core and rock armour using split hopper barges, jack-up barge platform and tugs

The works are being carried out by marine civil engineering contractors working from a temporary quay at the Queensport in Greencastle and the Greencastle pontoon using work vessels, jack up barges, heavy civil engineering plant and equipment. Divers may also be employed from time to time on site.

For safety reasons, mariners are advised to proceed slowly and with caution within the area south-west of the entrance to Greencastle Harbour and to give the works area a wide berth. Wave wash from vessels should be avoided.

A map and plan of the planned works as well as contact details can be found in Marine Notice No 38 of 2023, attached below.
