How we are improving highways maintenance

Page Contents

We are committed to improving the condition of Cambridgeshire’s highways enabling better and safer journeys for those who live, work, or visit our county. 

We recognise that Cambridgeshire's residents care deeply about the condition of the highways network, and we are committed to delivering highway maintenance activities and services to a high standard. 

Over the past two years, we have made the biggest investment in the highways network in over a decade, providing £43 million of additional funding for highways maintenance. 

We have also allocated a further £20m for 2026/27 to help us continue our mission to improve the overall condition of the network year-on-year.

Our priorities

Value for money

The amount of funding we have to spend each year is limited. How and where we spend the highways maintenance budget is important. We have processes to prioritise how we invest the highways maintenance budget in the most efficient and cost-effective way. Ensuring we maximise every pound we spend.

Community focussed

We deliver highway maintenance services on behalf of residents. We are committed to ensuring services are rooted in communities and respond to local needs effectively and efficiently.

Customer experience

How we communicate is an important part of delivering a positive customer experience. Highway maintenance work can cause disruption so we inform communities when work is taking place, via social media, digital maps and roadside signage. We are making progress on improving customer experience to make sure we communicate openly and transparently with everyone who uses Cambridgeshire's highways network.

Continuous improvement

The needs of our communities and demands on the highways network are constantly changing. It is important we keep looking into the future and planning. We are reviewing our existing highway contracts and services and looking ahead to how highway maintenance will be delivered in future.

Innovation and best practice

We are continually working to lead best practice and deliver innovation and efficiency. Find out more below about how we are innovating to decarbonise our maintenance operations and to reduce the impact of a changing climate. We are also one of the first authorities to use data to prioritise how we select capital funded projects.

Last year, we switched to using a cold laid recycled asphalt material instead of traditional hot asphalt material across our active travel network. In total we laid 2,000 tonnes of material.

This enabled us to:

  • Reduce health and safety risks linked to working with hot products.
  • Decrease the noise pollution and vibration linked to our work, by reducing the number of site deliveries.
  • Work more efficiently, by increasing the time we had to lay the material.
  • Significantly reduce the amount of carbon per tonne used when compared to traditional asphalt material.

Doing this resulted in a total carbon saving of 110 tonnes carbon dioxide equivalent and delivered a cost saving of 15%, compared to regular asphalt. This means we can do more repairs with the same amount of funding.

For several years, we have been leading the way in sustainable construction practises when rebuilding Cambridgeshire’s roads.

The process we use involves recycling existing material into the lower layers of the new road. Doing this has significant cost and carbon savings.

We use performance-enhancing grids when doing this to further extend the life of the road and address issues caused by soils underneath the road moving.

Last year we recycled 41,000 tonnes of material, saving 305 tonnes carbon dioxide equivalent.

We have also been using materials supplied at a lower temperature than conventional materials and with an increased percentage of recycled aggregate included.

This is known as a warm mix product.

Using warm mix product across our road resurfacing programmes has both quality and carbon reduction advantages.

From a quality point of view, heating the material to a lower temperature means the road is not as brittle. From a carbon saving perspective, we have saved 340 tonnes carbon dioxide equivalent.

Finally, we have trialled the use of low carbon cements within our road reconstruction projects.

This is a process whereby the existing road is broken down, degraded, and mixed with cement to provide the new road material.

Traditionally, conventional cement has been used when following this process but this comes at a high carbon cost.

We switched to low carbon cement across several of our sites in 2024/25 and this enabled us to save 320 tonnes carbon dioxide equivalent.

Building on the successes above, we have recently secured £1.5 million from the Peterborough and Cambridge Combined Authority (CPCA) to design and deliver a series of soil affected road repair trials.

This gives us the opportunity to find potential solutions and build a case for further investment from central government that is data led.

Tackling this issue is critical in Cambridgeshire since 40% of our road network is classed as soil affected and deteriorates at a much faster rate than traditional roads. It has been estimated that the county’s soil affected roads will require in excess of a further £530m in funding to address this issue. 

As a result, a greater proportion of highways maintenance funding goes on maintaining these routes, and this in turn impacts how much we can spend across the rest of our network.

We are one of the first local authorities to develop an Active Travel Hierarchy to reflect how important well-maintained routes are for those walking, wheeling, and cycling.

Specific active travel hierarchies are not in widespread use by local highways authorities for maintenance activities and Cambridgeshire is an early adopter of their use to support active travel.

Our proposed active travel network will help ensure that the county’s highways are maintained with due regard to the needs of active travel and non-motorised users of the network.

The hierarchy will be used to prioritise capital maintenance schemes by assigning scores to routes that are ranked higher in the hierarchy.

This will build on the adoption of Cambridgeshire's Active Travel Strategy

You can find out more about the active travel hierarchy by viewing the 4 March 2025 Highways and Transport Committee meeting agenda item: Active Travel Hierarchy - adoption of completed Hierarchy (opens as pdf on cambridgeshire.cmis.uk.com).

How we spend our funding is important. We have a limited amount each year and it is vital  to spend this is the most efficient and effective way we can.

To do so, we are one of the first authorities to develop a method of prioritising projects for capital funding. 

This allows us to follow an objective, data-led approach when identifying new projects for capital maintenance.

These projects then form the basis of our capital maintenance and improvement programme,  which goes before our Highways and Transport Committee in March each year.

You can find out more about this innovative approach by viewing the 3 December 2024 Highways and Transport Committee meeting agenda item: Prioritisation of the Highways Capital Programme (opens as pdf on cambridgeshire.cmis.uk.com).

The council's Highway Operational Standards (opens as pdf) sets out how we will manage and maintain the highways.

It brings together the County Council Corporate Business Plan and the Combined Authority’s Local Transport Plan objectives.

We apply the principles of asset management to ensure we meet the requirements of our communities and users and also deliver value for money.

We tailor our approach to meet the needs of Cambridgeshire, whilst also recognising national best practice.

By doing so, we take into account issues such as sustainability and growth pressures.

Our operational standards:

  • Define affordable highway service standards and how these will be operationalised by our teams.
  • Publish our investment and maintenance strategies, linked to lifecycle planning for key highway asset groups.
  • Improve the way in which our highway is managed and maintained, making use of innovation and digitisation wherever possible.
  • Enable us to ensure value for money through efficient and effective highway service provision by following a data led approach to highway maintenance where appropriate.

The standards are informed by the national Code of Practice (CoP) 'Well Managed Highway Infrastructure' (opens as pdf on ciht.org.uk).

The code contains fewer prescriptive standards than the previous version and promotes a more risk-based approach. Our standards reflect the authority’s implementation of the key elements of this code.

We are currently reviewing our Highways Operational Standards. This review will be completed later this year and changes implemented soon after. This is part of our commitment to continuous improvement and learning.

Transparent reporting of highways maintenance

The Department for Transport (DfT) requires us to publish a yearly report that details our highway maintenance activities and investment plans across key areas.

This report details:

  • How much funding has been allocated for highway maintenance activities
  • The condition of our local roads
  • Our plans and strategies
  • Our approach to climate change, resilience, and adaptation
  • How we manage road works

A copy of this report, providing a detailed breakdown of the headline figures for 2025/26 can be found below.

Key highlights

  • Over the last five years, we have repaired an average of 55,400 individual potholes every year.
  • Since 2023/24 the amount of capital funding we spend on highway maintenance has increased by £35m, from £24m to £59m.
  • Often for reasons outside our control, such as changing climate and rising demand, the overall condition of our road network has deteriorated over the last five years. This is why we are investing more of the council's reserve funds in highways maintenance and lobbying central government for further funding. The soil affected roads in Cambridgeshire put unique financial pressures on our overall highways maintenance budget.
  • We are committed to managing roadworks as efficiently and effectively as possible, to reduce disruption to highway users. We do so through the use of digital tools and working collaboratively to plan and coordinate. 
  • It is our priority to ensure that our communities and visitors to the county are well informed about what is happening on our network, and when, so they can plan their journeys.
