Roads in Ireland – Network, Condition and Investment

Roads in Ireland carry the vast majority of passengers and freight across the country. Despite growing investment in public transport and active travel, the road network remains the backbone of how people get to work, school, hospital appointments and everything in between. With over €1.5 billion allocated in 2026 alone – a 13% increase on the previous year – roads continue to command the single largest share of transport spending.

This article examines the structure, condition and funding of Ireland’s road network, from high-speed motorways to the rural lanes that connect the country’s most isolated communities.

🛣️ How the Road Network is Structured

Ireland’s road network is divided into four main categories, each with different standards, speed limits and management arrangements.

National roads form the top tier. The national primary and secondary network extends approximately 5,306 kilometres and is made up of motorways, dual carriageways and single-lane national routes. This network is managed by Transport Infrastructure Ireland (TII) and carries roughly 45% of all road traffic despite making up only about 6% of total road length. Most of Ireland’s freight is distributed along these routes, with over 65 million vehicle journeys monitored annually through TII’s national control centre.

Regional roads connect smaller towns to each other and to the national network. There are over 13,000 kilometres of regional roads, numbered with three-digit “R” prefixes. The majority are single carriageway, though some important urban routes like the R136 Dublin Outer Ring Road and the R710 Waterford Outer Ring Road include dual carriageway sections. Regional roads carry a speed limit of 80 km/h outside built-up areas.

Local roads make up the vast majority of the network – over 83,000 kilometres of roads ranging from wide urban streets to narrow rural lanes known as boreens. Local roads are divided into three sub-categories: local primary (wider than 4 metres), local secondary (narrower than 4 metres) and local tertiary (cul-de-sacs and minor roads). Since February 2025, the general speed limit on local roads has been reduced from 80 km/h to 60 km/h.

All regional and local roads are maintained by the 31 local authorities, funded through a combination of central government grants and their own resources. For a broader overview of how the road network fits into Ireland’s wider transport system, see our guide to transport in Ireland.

💰 Road Funding in 2026

The Government has allocated over €1.5 billion in exchequer funding for national, regional and local roads in 2026. This represents a significant step up from the €713 million spent on regional and local roads alone in 2025, and reflects increased recognition of the need to maintain and improve the existing network alongside building new infrastructure.

The national roads allocation of approximately €800 million breaks down into three main streams: €659 million in capital funding through TII, €104 million for national roads under Public Private Partnerships and roughly €33 million for regular maintenance provided directly to local authorities. This funding covers road safety improvements, pavement and bridge renewal, climate resilience measures and the progression of new national road projects including the Adare Bypass, the N5 Ballaghaderreen to Scramoge and the M28 Cork to Ringaskiddy.

The €718 million allocation for regional and local roads will enable approximately 2,800 kilometres of roads to be maintained and 2,330 kilometres to be improved. Key funding streams within this allocation include €50 million for strategic road improvement projects, €20 million in specific grants for bridgeworks, junction reconfigurations and traffic congestion relief across 99 funded projects, €16.5 million for 294 climate adaptation and resilience projects, €14 million for 280 low-cost road safety measures, and €16.2 million for a new two-year Community Involvement Scheme programme.

The largest allocations go to the counties with the most extensive road networks – Cork received over €94 million, Galway over €63 million, Donegal over €42 million and Tipperary over €42 million. Dublin’s local authorities receive comparatively small allocations because the city’s road network is shorter and its maintenance needs differ from rural counties.

🔧 Road Condition – The Maintenance Challenge

The condition of roads in Ireland varies enormously depending on their classification and location. National primary routes, particularly the motorway network, are generally maintained to a high standard with continuous hard shoulders, crash barriers, superior lighting and regular pavement renewal programmes.

Regional and local roads tell a different story. While increased investment over the past two decades has significantly improved the overall standard – particularly since EU structural funding and Celtic Tiger-era spending brought many routes up to international standards – the sheer scale of the network means that maintenance backlogs persist. Many rural roads suffer from narrow widths, poor drainage, inadequate signposting and surfaces that deteriorate quickly under heavy agricultural traffic and severe weather.

Climate change is compounding the maintenance challenge. Increased rainfall intensity and more frequent storm events are causing accelerated deterioration through flooding, landslips and subsurface damage. Storm Chandra in early 2026 alone is estimated to have caused approximately €50 million in road damage. The €16.5 million allocated to the Climate Change Adaptation and Resilience Programme in 2026 covers 294 individual projects focused on better drainage, flood defences and resilience measures, but these represent only a fraction of what is needed.

Local authorities are advised to hold 10% of their annual road allocations in reserve to deal with severe weather events – an indication of how routine weather damage to the road network has become.

⚠️ Road Safety – A Worsening Picture

Road safety on Irish roads has deteriorated significantly in recent years. A total of 185 people lost their lives on public roads in 2025, up 8% from 171 in 2024 – the highest toll in over a decade. Drivers accounted for 41% of fatalities, pedestrians 22%, motorcyclists 16%, passengers 11% and pedal cyclists 8%. The number of cyclists killed was the highest since 2017, while motorcyclist fatalities reached their highest level since 2007.

Almost three in four road deaths between 2020 and 2024 occurred on rural roads with speed limits of 80 km/h or higher. Counties with large rural road networks – including Mayo, Donegal and Galway – consistently report high fatality rates per head of population.

Ireland’s Road Safety Strategy 2021-2030, guided by the Vision Zero goal of eliminating all road deaths by 2050, aims to halve fatalities and serious injuries by the end of the decade. The strategy is backed by a projected €3.8 billion investment and is built around the Safe System approach, targeting safe roads and roadsides, safe speeds, safe vehicles and safe road use. However, Phase 1 of the strategy (2021-2024) saw fatalities rise rather than fall, and a Speed Limit Review carried out by experts and peer-reviewed by Swedish specialists has faced political pushback at the implementation stage.

The 2026 road funding allocation includes €14 million for 280 low-cost road safety projects targeting vulnerable road users, and the broader Vision Zero strategy continues to inform how roads are designed, maintained and policed.

🚛 Roads and Freight

Road freight dominates goods distribution in Ireland. Approximately 95% of freight carried by road is on national journeys, with the total quantity of goods transported by road exceeding 141 million tonnes in recent years. The national road network, despite comprising just 6% of total road length, carries the bulk of this freight alongside approximately 45% of all road traffic.

Heavy goods vehicles place significant strain on road surfaces, particularly on regional roads that were not designed for current traffic volumes and axle weights. TII monitors traffic flow and vehicle classification across the network, with data from Dublin, Rosslare and Cork ports feeding into monthly dashboards tracking HGV movements. The continued growth of e-commerce and distribution logistics is increasing demand on the road network, particularly around key freight corridors and port access routes.

The M28 Cork to Ringaskiddy project, currently under construction, is specifically designed to improve access between Cork and the deep-water port at Ringaskiddy, reflecting the strategic importance of road infrastructure to Ireland’s freight and trade capacity.

⏱️ Speed Limits and Reform

Speed limits in Ireland are expressed in kilometres per hour, a change introduced on 20 January 2005 when the country moved from imperial to metric speed measurement. The current default limits are 120 km/h on motorways, 100 km/h on national roads, 80 km/h on regional roads and 60 km/h on local roads (reduced from 80 km/h in February 2025). Built-up areas carry a general limit of 50 km/h, with many town centres now moving to 30 km/h under the Road Safety Strategy.

The 2023 Speed Limit Review, conducted by experts from Ireland’s main road engineering agencies and peer-reviewed by Swedish specialists, recommended reducing default speed limits on certain rural roads and introducing a 30 km/h default in urban cores – including housing estates and town centres. The previous government legislated for these changes through the Road Traffic Act 2024.

However, the implementation of reduced urban speed limits has proven politically contentious. The original plan for a national default 30 km/h urban limit was repackaged into an optional system where individual local councils vote on adoption, rather than a mandatory national standard. Critics, including road safety advocates, argue this approach risks turning evidence-based road safety into a localised political debate. Supporters contend that local discretion allows communities to make decisions appropriate to their specific conditions.

The speed limit changes are directly relevant to road safety outcomes. Research consistently shows that reducing speeds from 50 km/h to 30 km/h in urban areas dramatically reduces the severity of collisions. At 30 km/h, pedestrians involved in collisions usually sustain minor injuries; at 50 km/h, the survival rate drops to roughly 50%. With 22% of road fatalities in 2025 being pedestrians and 8% cyclists, the debate over urban speed limits has real consequences for Ireland’s most vulnerable road users.

🔌 Electric Vehicles and the Road Network

The transition to electric vehicles is adding a new dimension to road infrastructure planning. As of 2024, approximately 8% of all vehicles licensed in Ireland were hybrid or electric (including plug-in hybrids), up from 6% in 2023. The Government’s decarbonisation targets depend on accelerating this transition, and the road network must accommodate the charging infrastructure needed to support it.

The 2026-2030 Sectoral Investment Plan includes dedicated funding for expanding the EV charging network alongside road construction and maintenance. New initiatives announced in late 2025 aim to expand the national recharging network and provide enhanced support for businesses adopting electric heavy-duty vehicles. The integration of EV charging into motorway service areas, urban car parks and Park and Ride facilities is becoming a standard consideration in new road projects.

🔮 Looking Ahead – €9.7 Billion for Roads to 2030

The 2026-2030 Sectoral Investment Plan commits €9.7 billion to roads over the five-year period, covering restoration work, new national and regional roads, bypasses and electric vehicle charging infrastructure. Major projects expected to progress include the Donegal TEN-T Project, the N24 Cahir to Limerick Junction, the Slane Bypass and, subject to planning, the long-awaited Galway City Bypass.

For rural communities, roads will continue to be the primary transport connection for the foreseeable future. The commitment of €360 million per year for active travel provides complementary walking and cycling options, but for the majority of rural Ireland, the quality of the local road network remains the single most important factor in transport connectivity.

The challenge for the next decade is balancing the protection and renewal of over 90,000 kilometres of existing roads with the construction of strategic new routes – all while adapting the network to climate change, improving safety and supporting the shift to electric vehicles.
