Early history

The first routes in Ireland were prehistoric trackways, some of which were later developed into roads suited for wheeled vehicles

A wheel is a device that allows heavy objects to be moved easily through rotating on an axle through its center, facilitating movement or transportation while supporting a load, or performing labor in machines. Common examples found in transport applications. A wheel, together with an axle,...

. Many of Ireland's minor roads “may well have had their origin in pre-existing paths and trackways aligned in direct response to the physical environment.” Traces of these evolved roads which developed over very long periods, frequently from tracks of the prehistoric period, are still evident. The routes of such roads usually followed the natural landscape, following the tops of ridges and crossing rivers and streams at fording points
Ford (crossing)
A ford is a shallow place with good footing where a river or stream may be crossed by wading or in a vehicle. A ford is mostly a natural phenomenon, in contrast to a low water crossing, which is an artificial bridge that allows crossing a river or stream when water is low.The names of many towns...

Similar wooden trackways and roads are known from all over Ireland from the Late Bronze Age. One example from Ballyalbanagh, Co. Antrim was seven feet (2 metres) wide and made from oak beams and planks: "its width suggests provision for cart or wagon transport."

Unlike Roman roads, these routes were not clearly physically defined:

It is important to remember that unlike, for example, Roman roads, these medieval routes were not essentially physical entities—thin strips of land with physical boundaries; rather they were rights of way, sometimes with legal and traditional status. Routes tended to follow the line of least resistance, twisting and turning to avoid poorly drained areas and land that was easily overlooked. Where there was a hill to climb or a difficult area to pass through, multiple tracks would develop, the traveller taking the easiest route. Routes may also have varied seasonally as changing weather affected the condition of the pathway.

(L. Doran: Medieval Communications Routes, 69).

Early medieval road terminology

Early medieval law-tracts set out five types of road:

the 'highway', slige, on which two carpait/carpenta [chariots] could pass without one having to give way to the other, the 'local road', rout [or ród], on which at least one carpat/carpentum and two riders can pass side by side as a regional main road, the 'connecting road', lámraite, a minor road connecting two major roads, the 'side road', tógraite, leading to a forest or a river, which private persons could rent, for which they then could extract tolls from people driving cattle on them , and finally the 'cow road', bóthar, which still had to be as wide as two cows, one standing parallel and one normal to the road.
(F. Kelly, Early Irish Farming. Early Irish Law Series vol. IV, Dublin 1997, 390 f.)

Conair and cai were general terms, given in Cormac's Glossary, for any type of road and "thirty-seven ancient roads [were] mentioned with the general name bealach", meaning 'pass

Late medieval roads

Roads were not the most important transport routes in later medieval Ireland: most long-distance travel between towns was undertaken by sea or via inland waterways. Road conditions were difficult, often dangerous, and long-distance travel by road was generally slow and uncomfortable. Giraldus Cambrensis

 gives an indication of the slowness of travel in 12th century Ireland, which he also describes as a "truly a desert land [i.e. sparsely populated], without roads, but well watered."

...Ireland extends from the Brandane mountains to the island of Columba, called Thorach, the length of eight good Irish days' journey, which is forty miles to the day; and from Dublin to St. Patrick's hills and the sea of Connaught it is four such days' journey in breadth.


Travel by sea was faster than by land and it was easier to transport goods in bulk by ship than by road; one estimate reckons that a ship could travel sixty to ninety miles (96 km to 145 km) per day whereas an overland traveller might cover a distance of only twenty-five miles (40 km).

Most tracks were not suitable for wheeled vehicles and pack animals were used to transport goods. Some attempts to improve routes were made in the Tudor

 passed the Highways Act which required local parishes to maintain roads within their boundaries serving market towns. The Act did not regulate the construction of new roads or bridges although it did encourage improvements to existing roads and the construction of new ones, especially roads linking market towns in the Ulster Plantation area. The organisation of road maintenance on a parochial basis is partly responsible for the large numbers of minor roads found throughout Ireland. In 1634, a new Act allowed for the levying of a tax "to ensure the repair, maintenance or reconstruction of bridges, fords or causeways." This formed the basis of the presentment system which was the main system for organising the construction and repair of roads and bridges in Ireland from 1634 to 1898.

The difficulties encountered by travellers on 17th century Irish roads are amply illustrated by extracts from contemporary accounts of journeys.

 in 1602 recounts that ...before we had ridden three miles we lost our way and were compelled to go on foot, leading our horses through bogs and marshes... The journey took two days. A few years later an account of the journey of a Scotsman through Ireland in 1619 and 1620 reflects the great difficulties which he encountered: Travelling in winter his horse constantly sank to its girths on the boggy roads, and his saddles and saddlebags were destroyed. Often he had to cross streams by swimming his horse, a dangerous procedure for, as he tells us, in five months he has foundered six horses.

From such accounts it may be deduced that in general whatever roads and tracks did exist at this time were quite unfit for use by any form of wheeled vehicle.

18th century

By the 18th century, Ireland had a well-developed network of roads, the principal ones being marked on Herman Moll

's New Map of Ireland (1714) which showed, amongst other features, "Passes, Bridges &c. with the Principal Roads, and the common Reputed Miles" between towns.

In 1765, new legislation gave county Grand Juries the power to "...present such sum or sums of money, as they shall think fit, upon any barony or baronies in such county for the repairing [of] old roads or making new roads through such barony or baronies...". The presentment system of funding roads lasted until 1898 and it was successful in providing Ireland with a system of public roads which English travellers such as Arthur Young commented favourably on:

...for a country so very far behind us as Ireland to have got suddenly so much the start of us in the article of roads is a spectacle that cannot fail to strike the English traveller exceedingly.


New roads had to be at least 30 feet (9.14 metres) wide between fences and drains, with a 14 feet (4.27 metres) wide gravelled surface. In 1777, maintenance contracts, allowing for regular maintenance, were established. Taylor and Skinner's Maps of the Roads of Ireland was first published in 1778 , with a second, revised edition in 1783. It provided detailed strip maps of the principal roads along with other topographical details.

From 1729, a network of turnpike roads

Turnpike trusts in the United Kingdom were bodies set up by individual Acts of Parliament, with powers to collect road tolls for maintaining the principal highways in Britain from the 17th but especially during the 18th and 19th centuries...

 (charging tolls) was built: "a turnpike was a primitive form of turnstile - a gate across the road, opened on payment of a toll. The average length of a turnpike road was 30 miles". Routes to and from Dublin were developed initially and the network spread throughout the country. Turnpikes operated between 1729 and 1858 when the extensive railway network made them increasingly unpopular. Turnpike roads were not as widely used in Ireland as they were in England

 because of the availability of toll-free alternatives, the roads built under the presentment system. Lack of traffic on some routes led to reduced toll income and maintenance was neglected. However, in the first quarter of the 19th century, mail-coach contracts increased income and the quality of turnpike roads improved. Turnpike roads were also used by horse-drawn carriage services, including the Bianconi coaches, established as a form of public transport

19th century

Although Ireland's road network was well developed by 1800, there were still many remote areas, especially in the western regions, that were not well served by roads. In 1822, government grants were made available for road building projects and roads were built to and in western counties. Newly-built roads spurred major changes in some areas:

Railways became the dominant form of land transport from the mid-19th century. This situation persisted until the first half of the 20th century when motorised road transport (cars, buses and trucks) gradually began to take over from railways as the most important form of land transport.

The 20th century saw a renewed emphasis on roads as the primary method of facilitating land transport. The increase in motor vehicle traffic on roads meant that urgent improvements were required to make roads suitable for all vehicles in the automobile

Road improvements: 1920s to 1950s

In 1922, the Irish Free State took over a network of public roads which required major improvements. Most road surfaces were made up of undressed and unrolled water-bound macadam

s. Main roads and county roads were funded by the county less the urban districts and urban roads were funded by the urban districts.

The 1925 Act also granted powers to order the removal or alteration of buildings, trees and hedges causing obstruction or danger, introduced a licensing system for the erection of petrol pumps and introduced powers to set speed limits and to regulate signposts.

Grants were made to local councils from the Road Fund for the improvement of roads and, later, their maintenance. By the 1930s, “the surfaces of the main roads had all been improved and attention could then be given to widening and improving alignment.” Main roads now had tarmac

 due to the scarcity of tar and bitumen. After the war, roads that had deteriorated due to lack of maintenance during the war were restored and other improvements were made: “the effect of all these measures was a marked improvement in both main and county roads.”

Trunk Roads and Link Roads

Various systems of road classification have operated in Ireland since 1925: the Local Government Act, 1925 divided roads into main roads, county roads and urban roads, giving the Minister for the Environment the power to decide which roads were main roads.

 are currently classified as motorways, National Primary routes, National secondary routes, Regional roads and Local roads. The introduction of this classification system began in 1977.

Prior to this, Ireland had a different road classification and numbering system. Roads fell into three categories: T (Trunk Roads), L (Link Roads) and unclassified roads. The origins of this system lie in pre-independence legislation: the preliminary section of Statutory Instrument S.I. No. 55/1926 — Road Signs and Traffic Signals Regulations, 1926 states that the Ministry of Transport Act, 1919 gave the Minister for Local Government and Public Health the power to assign a "route letter and number" to a road, while Section 6.4 of Part I of the Regulations specified the positioning of the "route letter and the number of the road" on directional signs. A reference in the Statutory Instrument to the "classification of roads as a 'Trunk' or 'Link' Road" indicates that a system of route classification and numbering was envisaged in the 1920s. However, at present, there is no information about when the Trunk and Link road-numbering system was actually introduced on signposts. Even though legal authority for the erection of directional signposts was given to local councils, the Automobile Association of Ireland

, Cork and Dublin.

Evidence that the Trunk Road and Link Road classification and numbering system had been well established by the 1950s is found in Statutory Instrument S.I. No. 284/1956 — Traffic Signs Regulations, 1956 which contains examples of several directional signs. The first and second examples show the T8 as the route to Wexford

 road-maps of Ireland from the 1950s show the Trunk and Link road network. Despite its long-standing use, the original Trunk and Link road system was never legislated for and the routes of Trunk Roads and Link Roads were never formally designated by law.

Current system

This current system of road classification, numbering and network management has its origins in the late 1960s. A 1969 study into road construction and management recommended a reclassification of the road system into national roads (primary and secondary), regional roads (primary and secondary) and county roads. This system, without the division of regional roads into primary and secondary categories, was later adopted.

On 23 July 1969 the Minister for Local Government, Kevin Boland

, announced that a national road network would be formed. In 1974, the Local Government (Roads and Motorways) Act came into effect. It allowed for designation of roads as motorways or national roads. National roads were first designated by Statutory Instrument S.I. No. 164/1977 on 1 June 1977. Twenty-five National Primary routes (N1-N25) and thirty-three National Secondary routes (N51-N83) were initially designated.

The changeover to the new system was gradual: a route planning map of Ireland from the late 1970s (or early 1980s), divided into a northern section and a southern section, shows a mixture of Trunk Road, Link Road and National route numbers. Many of the remaining classified roads became Regional roads (formally authorised under the Roads Act 1993, route-numbers having been present on road signs on a non-statutory basis for some years previously) and their routes were designated under a Statutory Instrument
Statutory Instrument

 ('SI') in 1994. The latest SI designating the routes of Regional roads was published in 2006: the Roads Act 1993 (Classification of Regional Roads) Order 2006. Other roads formerly classified as Trunk or Link roads eventually became Local roads under the 1993 Act which states that "a public road, other than a national road or a regional road, shall be a local road".

The 1993 Act gave local authorities the duty to "assign a number or other identifying mark to each local road in respect of which it has responsibility". Local Road numbers have been used for administrative purposes since the Act came into effect, but Local Road numbers did not generally appear on directional signposts until the late 2000s. Most road-maps do not show Local Road numbers, although some are marked on OpenStreetMap

Two major driving forces behind the establishment and growth of OSM have been restrictions on use or availability of map information across much of the world and the advent of inexpensive portable GPS devices.The...

Older signs showing the former Trunk and Link road designations are still to be seen in some locations. The L (for Link Road) prefix on these signs is not connected to the network of Local roads currently in place.

Road improvements: 1980s and 1990s

In 1979, in the wake of new EU laws and with the availability of EU funding, a strategic plan for the development of the national road network was published, entitled "Road Development Plan for the 1980s". The plan's main aims were:

  • the provision of an adequate strategic inter-urban road system connecting the principal towns, seaports and airports
  • the adoption of a minimum two-lane standard for the national route network with higher standards for particular sections
  • the provision of bypasses of a number of towns on the national routes
  • a programme of new river crossings, ring roads and relief routes in the cities and other major urban centres



The National Development Plan (1989–1993) set out a programme of road improvements costed at €1,257 million (1989 prices): it "included thirty-four major improvement projects involving the provision of dual carriageway or motorway on 290 kilometres of national primary routes"; another 290 kilometers were to be upgraded to wide single carriageway

 standard (7.3 metre carriageway plus two 3 metre hard shoulders). A further €3,316 million (1994 prices) was spent on national primary routes between 1994 and 1999. Four key strategic corridors were identified for major improvements. These programmes meant that by the end of 1993, 35% of the national road network was "adequate or improved", 53% (with improvements to another 11% of the network underway) by the end of 1999.

Some changes were made to the national road network in the 1980s and 1990s. In 1980, two national secondary roads (N84

As of 31 December 2007, there was a total of 5,427.58 km of national roads: 2,743.606 km of national primary routes (including motorways) and 2,683.974 km of national secondary routes. The total length of the national road network varies annually for different reasons:

  • The opening of a new section of road that is classified as a national road thereby replacing the old route
  • Re-alignments to existing National Roads
  • Changes to the classification of roads.
  • Analysis and updating of data contained in the Roads Database

As of 2009, all motorways in Ireland are part of, or form, national primary roads. There has been a considerable amount of motorway (and dual carriageway) construction in recent years: at the end of 2003 there were 176.33 km of motorway in the Republic and 244.79 km of dual carriageway forming part of national roads. By the end of 2004 there were 191.71 km of motorway and 285.49 km of dual carriageway. This was extended, by the end of 2005, to 246.62 km of motorway and 308.4 km of dual carriageway (including 2+1 road

In 2008, another 125 km of newly constructed motorway were completed and some sections of dual carriageway on national routes were re-designated as motorways. There are 431 km of motorway and dual carriageway currently under construction with many more schemes at various planning stages; 145 km of newly constructed motorway and dual carriageway is due for completion in 2009, with another 286 km due for completion in 2010.

In July 2008, S.I. No. 279 of 2008 was signed: it redesignated a number of roads, either already open, under construction or proposed, as motorways.

Total 1052 km National motorway network.


If all these motorways are opened, Ireland will have a ratio of 1 km of motorway to every 4,277.56 people (assuming a population of 4.5 million) by 2015. This compares to a current ratio of 1 km of motorway to every 6,017.32 people in Belgium. Although welcomed by many people, the construction of new motorways in Ireland has not been without controversy or opposition. In particular, the construction of the M3 motorway through the archaeologically significant Tara-Skryne valley (or Gabhra) near Tara has led to protests and calls for protection of its landscape from many, including Pat Wallace, Director of the National Museum of Ireland

Roads in Northern Ireland

After the partition of Ireland into two states in the 1920s, the road system in Northern Ireland developed very differently to the road system in the Irish Free State (later the Republic of Ireland). A modified version of the British road numbering system was adopted. Numbered roads were initially divided into two classes, A roads and B roads, with motorways being added to the system from the 1960s. In the early 1920s, local authorities in Northern Ireland were given grants from the Roads Board which they used to build new roads and repair and maintain existing roads. The grants were also used to help reduce unemployment by providing work on the roads. Taxes raised through Motor Licence Duties were also used to fund roads. New roads, such as the Great Western Road between Belfast and Antrim

, continuing south to join the N1 at the border from where it continues mainly as motorway to Dublin. The A1 was gradually converted from single-carriageway to dual-carriageway between 1971 and 2009. The most extensive scheme planned at present is the up-grading of the A5 from Derry to the border at Aughnacoly, Co. Tyrone from single- to dual-carriageway as part of the A5 Western Transport Corridor. Sixty percent of the funding for this scheme has come from the government of the Republic.

In 1964, ambitious plans to build a network of motorways throughout Northern Ireland were announced by Northern Ireland Minister of Home Affairs, William Craig. The plans included the construction of the following motorway schemes:
