A $300 million transatlantic cable is being brought ashore at Killala in Co Mayo this evening.
The cable will provide a super fast internet connection and is expected to be a major economic boost for the west.
The fibre optic cable is owned and operated by Irish company Aqua Comms and will run directly from Ross Strand in Killala to Long Island, New York.
It has the capacity to handle up to one third of the world's telephone calls and can cover the entire internet traffic of Europe and the US.
The system will enable 53.8 millisecond transfer speeds across the Atlantic when it goes live in early 2016.
The new digital infrastructure is expected to create a significant number of jobs and business opportunities in the western region.
Taoiseach Enda Kenny is attending the landing of the cable.
