Northern Ireland spent £466m on roads: why only £136m was structural maintenance
Northern Ireland spent £466 million on roads in 2024–25, but that headline does not mean £466 million was allocated to potholes. Official statistics show a much smaller structural maintenance budget, tens of thousands of surface-defect repairs and a road network stretching almost 26,000 kilometres.
A headline budget is not a pothole-repair fund
Official Department for Infrastructure statistics show £466 million of expenditure on Northern Ireland’s roads in 2024–25, up 1.8% from £458 million the previous year. Structural maintenance accounted for 29.2% of that sum, or £136 million. New construction and improvement accounted for a further £102 million, or 21.8%.
Those categories explain why it would be misleading to say that the government had £466 million available for repairing worn road surfaces. The total encompasses different kinds of road activity, including investment in construction and improvements rather than repairs to existing carriageways.
The figures also relate to a completed financial year: April 2024 to March 2025. They must not be presented as a real-time October 2026 roadworks budget or combined without qualification with grants and projects announced later.
Where the road money was allocated
The £136 million structural maintenance budget included more than £107 million in capital expenditure and approximately £28 million in resource expenditure, according to the official release. The capital-versus-resource split is an accounting distinction; it should not be simplistically translated into “money spent on big roads” versus “money spent on local roads”.
The £102 million for new construction and improvement is a separate category. A bypass, junction improvement or other development can improve journeys and capacity but does not automatically eliminate potholes on unrelated streets. Conversely, maintenance of existing road surfaces is not necessarily as visible as a newly opened road scheme.
Adding the two published categories gives £238 million, but that is not a statement that every remaining pound was spent on one other named activity. Other road expenditure comprises multiple categories recorded in the full official tables, and the headline release does not justify inventing a tidy breakdown of them.
The road network in numbers: 25,970 kilometres
At 1 April 2025 Northern Ireland had 25,970 kilometres of public roads. Unclassified roads made up 61.2% of the network by length, C roads 18.2%, B roads 11.3%, A roads 8.9% and motorways only 0.4%. That distribution explains why an exclusive focus on motorway resurfacing would overlook much of the infrastructure used daily by rural households, businesses and local communities.
Road class is not the same thing as traffic use, expenditure or maintenance need. A short strategic route can carry an enormous amount of traffic, while the long tail of lower-classification roads creates a different maintenance challenge across a wide geography.
A sensible assessment of value for money therefore needs more than a map of where construction announcements were made. It also needs to ask about the condition of the network, how inspection priorities work and which defects received repairs.
More than 91,000 surface defects instructed for repair
DfI recorded 91,715 surface defects instructed for repair following inspections in 2024–25 and 81,483 surface defects repaired. This is evidence of substantial maintenance activity, but subtracting one figure from the other and calling the result “the number of potholes left unfixed” would be wrong.
The official statistics explicitly warn that defects recorded and defects repaired within a financial year are not directly comparable because of differing timing. Some repairs completed during the year may address defects instructed earlier, and some instructions near year-end may be completed later.
Nor does one repair instruction necessarily mean one hole of a standard size. Defects vary in type, severity, area and repair requirement. A localised carriageway problem, for example, is not comparable to the complete resurfacing of an extended section of road.
The release reports that repair instructions fell by 11.6% and completed repairs fell by 13.0% compared with 2023–24. Those movements alone cannot identify whether the overall road surface improved: inspection activity, weather, definitions and work scheduling all influence the counts.
What the road-condition surveys actually say
For A-class roads surveyed using the SCANNER method, 80.0% were categorised in generally good condition, 17.7% in average condition and 2.4% in poor condition requiring further investigation. Because the figures are rounded, the individual percentages need not total exactly 100%.
The Department also reported that 91.9% of the combined motorway and trunk road network had more than five years of residual life in its substructure, based on the Deflectograph assessment. That measure concerns the road base, not whether the surface is smooth or free of potholes.
A road can therefore have a surface defect while its underlying structural life remains comparatively strong. Equally, an attractive-looking surface is not proof that its supporting structure will remain sound indefinitely. These are separate engineering measures and should be described as such.
Why drivers can still encounter poor surfaces
There is an unavoidable geographical challenge in maintaining nearly 26,000 kilometres of road. Thousands of local roads may require inspection, patching, drainage work, edge repairs or more extensive resurfacing. Priorities involve safety, condition, network importance and the budgets available in the relevant period.
Weather, drainage and heavy use can accelerate deterioration, while reactive repairs may address an immediate defect without resolving why an area of road is repeatedly failing. Planned structural maintenance, by contrast, aims to extend service life but normally requires larger coordinated schemes.
This is why a newly announced roads budget should not be treated as an automatic answer to a specific defect outside somebody’s home. The relevant questions are whether the defect has been inspected, which repair standard applies and whether that particular stretch forms part of the programmed works.
What the spending figures do not tell us about councils
The official national total does not give sufficient evidence to rank the 11 council areas by a simple share of the £466 million. Northern Ireland’s road network is maintained by the Department for Infrastructure, and road expenditure does not automatically follow local government district boundaries in the same way as ordinary district-council spending.
The Department publishes supporting tables and local-government-district infographics on road network and condition. Those are useful for understanding measured condition in different areas, but a condition chart is not a complete statement of all funding spent in that district.
A credible council-by-council spending investigation would require a verified dataset attributing expenditure by location and category, a clear treatment of strategic projects crossing boundaries and an explanation of whether any figures represent commitments or actual spend. Those records would need to be checked before a league table could be published.
The most important question for the next statistics release
The central finding is straightforward: Northern Ireland spent £466 million on roads in 2024–25, but only £136 million was classified as structural maintenance. At the same time, the Department recorded tens of thousands of surface defects requiring repair and a network spanning nearly 26,000 kilometres.
Neither the total budget nor the defect count on its own establishes whether road users are getting better value. The evidence has to be read together: money spent by activity, road condition, repair outcomes and the condition of the long network of local roads.
The next annual release should be assessed against those same measures rather than a headline spending figure alone. That is the strongest basis for judging whether Northern Ireland is actually moving towards more resilient roads.
