High Quality Content by WIKIPEDIA articles! The N8 road is a national primary road in Ireland, connecting Cork with Dublin via the M7. The road is motorway standard from junction 19 on the M7 to the Dunkettle interchange outside Cork city. From here the route continues into Cork city and terminates at the N22 at Patrick Street. The M8 motorway was completed in May 2010, replacing the single carriageway sections of the old N8 and bypassing towns on the main Cork to Dublin road. It is now possible to travel from Cork to Dublin on the M/N8 in about 2 hours 30 minutes. The route commences just south of Portlaoise, and reaches Cork via the midlands and the Golden Vale of Ireland, through Counties Laois, Kilkenny, Tipperary, Limerick and Cork. The N8 is further classified by the United Nations as the entirety of the (partially signed) European route E 201.
