Atlantic Corridor


The Atlantic corridor or Atlantic motorway is a road project in Ireland. The scheme announced in 2005 was intended to link Waterford in the South-East to Letterkenny/Derry in the North-West via motorway or dual carriageway by 2015, however due to the Great Recession major sections of the roadway were delayed or cancelled.
The Atlantic Corridor, when combined with the inter-urban motorways linking Dublin and the other cities, will effectively ring the island of Ireland, while at the same time connecting the primary population and economic centres.

National primary roads

The constituent routes are:
As of 2018, over 100km of the route is completed motorway or dual carriageway. The next construction planned is the M20 from Cork to Limerick, which has been allocated €850 million in government funds under the National Development Plan 2018-2027 capital scheme. The M20 will link with the planned Cork northern ring road, also forming part of the Atlantic Corridor route, connecting the planned Cork to Limerick motorway with the partially completed Cork-Waterford N25 dual carriageway.
