National Primary Roads

N4

The national primary route N4, Dublin to Sligo is a strategic corridor from Dublin to the northwest and border counties and is approximately 198km in total length. The route passes through Dublin, Kildare, Meath, Westmeath, Longford, Leitrim, Roscommon and Sligo. It is recognised as being particularly important in enhancing accessibility to some of the most peripheral areas in the northwest and west of the River Shannon.

N16

The N16 road is a national primary road in Ireland. It begins in County Sligo in the northwest of Ireland, and ends at Blacklion, County Cavan, at the border with Northern Ireland, where it becomes the A4 road. This road is currently in the process of consultation under the "N16 Munakill Realignment Scheme". There is more information on our dedicated page below.

Starting in the town of Lifford, Co. Donegal this road enters county Leitrim at the County boundary with Donegal, directly west of Bundoran and bypassing Tullaghan which is the only village along the N15 in our county, leaving the county boundary at Bunduff bridge, bordering with county Sligo.
