Category:N Roads in the Republic of Ireland

National (N) roads are the major roads in the Republic of Ireland, that are funded by the National Roads Authority. They are split into two classes - National Primary (N1 - N50) and National Secondary (N51 - N99). Not all numbers are currently used.

National roads are signed in green, and generally are the only roads to have a speed limit higher than 80km/h.

The scheme was first announced in 1977, where the N1-N25 and N51-N83 were allocated. Since then, the list of National Roads has changed, primarily due to the introduction of Motorways. Due to the legislative system in Ireland, motorways are legally National Primary Roads, and always replace the corresponding N road number on signs. For example, the M6 (Republic of Ireland) largely supersedes the N6, except for where the road is not to motorway standard.
