Maintaining roads

Local highways maintenance transparency report 2026/27


How we maintain local roads, pavements, and the wider highway network in Devon County Council

Devon County Council manages the largest local highway network in England, extending to over 13,000 km and serving communities, businesses and visitors across a predominantly rural county.

The network includes:

  • Carriageways: 13,131 km
  • Footways: 2,810 km
  • Cycleways: 1,049 km
  • Bridges and structures: 4,834
  • Street lighting assets: 92,227
  • Traffic signals: 400
  • Drainage gullies: 205,432

The network also includes many other assets that help keep people moving safely and efficiently.

Maintaining a network of this scale presents significant challenges. Much of Devon’s highway network comprises rural roads that provide essential access for residents, businesses and emergency services but are costly to inspect and maintain due to their extent and geographic spread.

Traffic growth, seasonal tourism and increasing demand created by new development place additional pressure on the network. Devon also manages a large number of bridges and structures, many of which require specialist maintenance and investment.

Weather-related impacts, including prolonged heavy rainfall, flooding, coastal conditions and storm events, can accelerate deterioration and increase maintenance needs. These challenges require a risk-based, asset management approach to help ensure investment is targeted where it delivers the greatest benefit to network safety, resilience and long-term value.

The scale, rural nature and geographic diversity of the network create unique maintenance challenges not faced by many authorities. Despite this, Devon continues to prioritise preventative maintenance and asset management-led investment to maximise long-term value.

Councils use road condition surveys to assess the state of their roads. The results are grouped into three categories:

  • Green – the road is in good condition and no further investigation or treatment is required
  • Amber – the road may need maintenance soon
  • Red – the road is in poor condition and should be considered for maintenance

The published official statistics for road condition include more detail about the methodology, timing and coverage of this data.

Additional information on carriageway condition

Devon County Council’s carriageway condition figures are derived primarily from machine-based SCANNER surveys, which use laser and imaging technology to assess defects such as cracking, rutting and surface texture. The Council extends survey coverage beyond statutory requirements to include unclassified roads on a rolling cycle, providing a more comprehensive understanding of network condition across all road classes. SCANNER data provides a consistent and repeatable basis for trend analysis but is supplemented by inspections, safety defect data, customer reports and local engineering knowledge.

Condition trends indicate that the classified network has remained relatively stable through sustained investment and targeted maintenance. However, parts of the unclassified network continue to experience increasing deterioration, reflecting the cumulative impact of historic funding pressures, repeated severe weather events, rural network characteristics and increasing maintenance demands. As unclassified roads represent over half of Devon’s highway network, they remain a key priority for future investment and asset management planning.

What we are doing about potholes and other road defects

What is a pothole?

Devon County Council defines a pothole as “an area of material loss resulting in a vertical edge depression”. In accordance with its published Highway Safety Policy version 6.1 a carriageway pothole is considered a ‘safety defect pothole’ where it is at least 40mm deep on a vertical face and 300mm in any horizontal direction. This is consistent with many local authorities and regularly tested in court.

Response times are determined by a risk assessment undertaken by qualified inspection personnel, considering location, hierarchy, traffic use and likely impact on highway users. Response times are determined as per the authority’s Highway Safety Policy and range from 2 hours, 7 days or 28 days, dependent on the risk score.

Devon’s extensive minor and rural network includes many evolved, historic and structurally fragile roads, which are more vulnerable to water ingress, traffic loading and freeze-thaw cycles that accelerate pothole formation, particularly in the winter months.

What we are doing to tackle potholes

Devon County Council tackles potholes through a combination of preventative maintenance, proactive intervention and risk-based repairs, aligned with national highway maintenance guidance.

During 2025/26, the Council identified and repaired approximately 58,000 potholes that met safety intervention criteria across the highway network. However, the priority is to prevent potholes from forming in the first place wherever possible. This includes investing in preventative carriageway sealing, targeted resilience patching, and coordinated maintenance on heavily used routes where early signs of deterioration are identified. By intervening earlier and using the most appropriate treatment for each location, we can reduce the number of potholes that develop, minimise repeat visits, reduce disruption for road users and communities, and achieve better long-term value from the Council’s maintenance investment.

Where defects are identified, the Council seeks to deliver permanent repairs whenever it is safe and practical to do so. Inspectors and operational teams are trained to select the most appropriate repair method for the condition and cause of the defect, helping to improve durability and reduce repeat visits. However, factors such as traffic management requirements, weather conditions, network safety and available road space can sometimes mean that a temporary repair is required initially before a permanent repair can be completed.

In 2026, the Council expanded its Pothole Repair Trial, enabling contractor teams in selected areas to repair some non-safety potholes while attending identified safety potholes. The trial aims to reduce repeat visits, make better use of resources and improve overall network condition.

The Council also supports local communities through its Road Warden Scheme, providing training and materials to volunteers who repair non-safety potholes on lower category roads, helping communities play an active role in maintaining the local highway network.

How members of public can report potholes and other highway defects

Members of the public can report potholes and other highway defects through a range of channels. The primary reporting tool is the online system available via the DCC corporate website, which allows users to pinpoint locations on an interactive map, upload photographs and provide supporting detail. Reports submitted online are routed through an internal works management system to the relevant team for inspection, investigation and triage. Defects can also be reported via a customer service centre by telephone, email or letter. Public reporting plays a key role in identifying defects between scheduled inspections. Reports can be submitted at Report a problem – Devon County Council.

What happens after a pothole is reported

All reported potholes and highway defects are assessed by a Highway Safety Inspector. Inspection timescales are based on the type and importance of the road, with busier roads inspected more quickly. Defects are assessed against the Council’s Highway Safety Policy to determine whether action is required. Where a safety defect is identified, an appropriate repair response is arranged. Reports that do not meet intervention criteria are recorded and monitored. Information from reported defects, including pothole clusters and recurring issues, is also used to help develop planned maintenance programmes, reducing future disruption and the need for repeated reactive repairs. Customers receive automated updates on the outcome of their report.

Our maintenance plans for this year

Our plans for highways maintenance for 2026-27

In 2026/27, Devon County Council will deliver a balanced programme of highway maintenance, supported by additional Council investment, focused on preserving asset condition, improving resilience and providing value for money.

  • Apply preventative carriageway treatments, including surface dressing and micro asphalt, to approximately 655 km of carriageway to extend asset life and reduce future maintenance costs.
  • Resurface approximately 36 km of carriageway on strategic and locally important routes.
  • Apply preventative footway treatment to approximately 36 km of footway to extend asset life and reduce future maintenance costs.
  • Deliver targeted resilience patching and drainage improvements to strengthen vulnerable parts of the network and improve resilience to severe weather.
  • Deliver risk-based investment across bridges, street lighting, traffic signals, cycleways and public rights of way, helping to maintain a safe, reliable and resilient network.
  • Continue year-round safety inspections, pothole repairs, winter service (gritting), vegetation management, gully cleansing, drainage maintenance, road marking renewal and other cyclical maintenance activities.

Together, these activities support Devon’s long-term asset management approach and help maintain a safe, resilient and serviceable network for residents and businesses.

Full list of planned carriageway and footway works

The dashboard below provides an interactive map and table showing currently planned carriageway and footway maintenance works for 2026/27. This is a live programme and may be updated throughout the year to reflect changing priorities, funding availability, coordination with utility works, road space constraints, weather events and other operational considerations.

The map and table focus on planned carriageway and footway maintenance activities and does not include all highway maintenance works undertaken by the Council. Other activities, such as bridge maintenance, drainage improvements, road restraint barriers, street lighting, traffic signals, public rights of way works and reactive repairs, are not shown. Routine patching works are also excluded, except where preparatory patching forms part of a planned preventative maintenance treatment.

How decisions are made on our maintenance plans

Devon County Council applies a risk-based asset management approach to planned highway maintenance programmes, targeting investment where it delivers the greatest benefit.

For carriageways, priority is given to classified and strategic routes due to their role in supporting traffic movement, economic activity and connectivity. This reflects a network hierarchy approach, recognising that it is not possible to maintain all roads to the same standard within available funding.

Programmes are developed using asset condition data, safety risk (inspection and defect information), and local intelligence. Interventions are timed to achieve best value, with a strong focus on preventative treatments that extend asset life and reduce whole-life cost.

Works are coordinated and combined where possible to maximise efficiency and minimise disruption. A balanced programme protects key routes while maintaining safety, access and serviceability across the wider network. The principles of a risk-based approach are applied across all asset groups, supported by asset-specific data to enable consistent, data-led decision making.
