More than half of the local road network in England and Wales is reported to have less than 15 years’ structural life left as the amount needed to fix the backlog of carriageway repairs increases to a record high of £16.3 billion.

That’s according to the Annual Local Authority Road Maintenance (ALARM) survey report, published on 19 March 2024 by the Asphalt Industry Alliance (AIA).

Now in its 29th year, the ALARM report is widely respected as the most authoritative and comprehensive study into local road maintenance funding and condition.

The report highlights the scale of the challenge facing local authority highway teams who have a statutory responsibility to keep local roads safe, but don’t have the funds to do so.

AIA says poor road conditions impact on people’s everyday lives, from the cost and inconvenience of damage to vehicles, to potentially causing accidents and injury to vulnerable road users such as cyclists – some of which have proven fatal.

Despite local authority highway teams reporting an overall increase in carriageway maintenance budgets, they have been hit by the impact of rising costs due to inflation, meaning they have been able to do less. This has been compounded by the increasing frequency of extreme weather events, which together are accelerating the rate at which the network is deteriorating.

ALARM data shows that only 47% of roads in England and Wales are classed as being in good structural condition, with the remaining 53% – more than 107,000 miles – now having less than 15 years’ structural life remaining. And, surface conditions are also reported to have declined, despite a 40% increase in the number of potholes filled over the last 12 months adding to the existing patchwork of previous repairs.

The findings, which relate to the 2023/24 financial year, show that in England and Wales:

  • Local authorities would have needed an additional £1.22 billion (an average of £7.2 million per authority) just to reach their own target road conditions.
  • It would now cost £16.3 billion to tackle the backlog of carriageway repairs and bring the network up to a standard from which it can be maintained efficiently and cost-effectively going forward.
  • Less than half (47%) of all local roads are reported to be in good structural condition meaning the remaining 107,000 miles (53%) could continue to deteriorate to the point of needing to be rebuilt within the next 15 years without appropriate maintenance measures taking place.
  • £143.5 million has been spent filling in 2 million potholes over the last 12 months.
  • Roads are only resurfaced on average once every 80 years.
