Atlantic Corridor

The scheme, announced in 2005, was intended to link Waterford in the South-East to Letterkenny in the North-West via motorway or dual carriageway by 2015.

[3] However, in part due to the post-2008 Irish economic downturn, 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, is intended to ring the island of Ireland and to connect primary population centres.

[citation needed] The constituent national primary routes, included in the 2007 plan, included: As of 2018, over 100 km (62 mi) of the route was completed motorway or dual carriageway.

The M20, which was "progressed through planning and design phases" as of 2010,[4] is proposed to 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.
