Ireland, both north and south of the border, has an extensive network of roads. Historically, Northern Ireland has had better quality roads, though the difference is less marked nowadays. It is true to say that many rural roads, even in Northern Ireland, remain an 'exciting' ride. For an unforgettable example, drive from Charleville to Macroom in County Cork; all the stereotypical components are present, from road 'surface' and potholes, to junctions and vicious bends (often combined for added thrills). With the advent of European Union funding, most National routes in the Republic continue to be upgraded. In the years from 1990s to the following decade the Republic went from having one motorway in the country, to expanding the motorways to most major routes. This was part of a National Development Plan. Road construction in Northern Ireland has proceeded at a slower pace in recent years, although a number of important bypasses and upgrades to dual carriageway have recently been completed or are about to begin.

Signposts in Northern Ireland denote distances in miles, while all signposts placed in the Republic since the 1970s use kilometres (a remnant of old signposts in the Republic still using miles will also be replaced with signs using kilometre distances before the end of 2005). Currently miles per hour speed limits are used north of the border. Those in the Republic use kilometres per hour.

Roads in the Republic of Ireland

The Republic's motorway network is focussed on Dublin, and is being extended to other major cities as part of the National Development Plan. Dublin has also been the focus of other major projects, such as the East-Link and West-Link bridges, as well as the Dublin port tunnel. Other cities and towns have however had bypass projects, some of which are still underway or in planning as of 2004. The Jack Lynch Tunnel under the River Lee (Ireland) in Cork was another major project outside Dublin, and a fourth crossing at Limerick of the River Shannon is in planning.

Motorways

In the Republic of Ireland, the most important roads are a small number of motorways, indicated by the prefix "M" followed by one or two digits. The motorway network is focused on Dublin. In all the intercity instances below, the Motorway is only part of the full route, the original route number is listed after. City names in brackets are the destinations served and signposted, but not directly connected to that route. In the Republic of Ireland, motorways inherit the route number of the "N" route they have replaced. In most cases, the bypassed section of road is reclassified as a regional route. New routes, such as the M50, are an exception. The M50 was chosen as a recognisable unique number. All motorways are simply classifications used on a national (N) route - so even the M50 was legislated as the "N50" route (despite having no non-motorway sections).

M1 Dublin - (Belfast) N1 road
M4 Dublin - Sligo/(Galway) N4 road
M7 Dublin - Limerick/(Cork)/(Waterford) N7 road
M9 (Dublin) - Waterford N9 road
M11 Dublin - Wexford N11 road
M50 Dublin ring road

National Primary Routes

This category of road has the prefix "N" followed by one or two digits. The most important routes are numbered N1-N11 ( radiate anti-clockwise from Dublin), with those in the range N12-N33 being cross-country roads. National Secondary Routes (see next section) are numbered under the same scheme with higher numbers. On road signage, destinations served but not on the route in question are listed in brackets, with the connecting route also listed.

Northern Ireland route sections (which are classified separately according to NI schemes) are in some cases included in a theoretical complete cross-border route – for example the N3 route, which re-enters the Republic. These are listed here in brackets for completeness (and are present on southern road signage).

This list ignores the sections of route reclassified as motorway (see previous section).

N1 Dublin - Dundalk - (A1 to Belfast)

N32 (Spur off M50 to Malahide Road)
N33 (Spur off M1 to Ardee)
(N50) Dublin ring-road. Only exists as the M50, but route set out in legislation as a primary (N) route. [1] (http://www.irishstatutebook.ie/ZZSI209Y1994.html)

Other Routes

National Secondary Routes are also indicated with a "N" prefix, though the number is higher. Examples are:

N69 Limerick - Tralee (Coast road via Foynes)
N71 Cork - Killarney via West Cork
N72 Killorglin - Killarney - Waterford
N81 Dublin - Tullow
N85 Ennis - Ennistimon

Regional routes are indicated with an "R" prefix and a three-digit number, ranging from R1xx in the north-east to R7xx in the south-east of the country. One of the more important regional roads is the R113 (Belgard) road, which forms a dual carrigeway between the N7 and N81 roads. Most regional roads are however regular highways, and a few are rather narrow.

Other roads are not generally referred to by number, but are registered with a four-digit "L" number, taking the form Lxxxx. Some old road signs will still carry the previous classifications, "T" for trunk road, or "L" for link road.

Roads in Northern Ireland

The main roads in the north, which connect well with those in the south, are classified "M"/"A"/"B" as in Great Britain, though their numbering is separate from the British system.

Motorways

The most important roads are motorways, designated as in the Republic and Great Britain by the letter "M". The motorway network is focused on Belfast.

M1 Belfast - Dungannon
M2 Belfast - Antrim, plus unconnected Ballymena bypass further to the north
M3 The Lagan Bridge in Belfast

M12 A short spur from the M1 to the centre of Portadown
