Opinion: Cornwall Has Quietly Built a Highways Model the Rest of Britain Should Be Studying

Britain's local roads are approaching a tipping point.

Every year, the same headlines appear. Potholes are getting worse. Budgets are getting tighter. Residents are becoming increasingly frustrated. Councils are forced into reactive repairs rather than strategic maintenance, while the cost of bringing the network back to an acceptable standard continues to climb.

The latest Asphalt Industry Alliance (AIA) ALARM survey estimates the backlog of carriageway repairs has now reached almost £17 billion. That figure has become symbolic of a system under enormous strain—one where ageing infrastructure, climate change, inflation and decades of inconsistent investment are colliding.

Against that backdrop, perhaps the biggest question facing local government is no longer simply how much funding is needed, but whether the current delivery model is capable of making the best use of the money available.

One council believes it has found part of the answer.

Cornwall's highways delivery model may not generate the headlines associated with major infrastructure projects or new technology, but it represents something arguably more valuable: a practical example of how public sector infrastructure can be delivered differently.

At the heart of the approach is the Teckal model, under which Cornwall Council retains ownership and strategic control of its highway assets while delivery is undertaken through its wholly owned company, Cormac.

On paper, that may sound like little more than an organisational structure. In reality, it fundamentally changes the relationship between client and contractor.

Rather than relying on traditional outsourced contracts that can encourage short-term thinking and transactional behaviours, the model aligns operational delivery directly with the council's wider objectives. Success is measured not simply by completed works, but by asset performance, public value, environmental outcomes and long-term resilience.

That distinction matters.

Across England, local authorities increasingly find themselves trapped in a cycle of emergency intervention. Budgets are consumed by repairing failures that might have been prevented years earlier. Preventative maintenance becomes the first casualty whenever finances tighten.

The consequences are predictable.

Roads deteriorate more quickly, reconstruction becomes more expensive, disruption increases and public confidence declines.

Cornwall has sought to reverse that cycle.

Instead of concentrating resources solely on roads that have already failed, greater emphasis is placed on preserving assets before they deteriorate beyond economic repair.

This asset management philosophy is hardly revolutionary—it has existed for decades—but relatively few authorities have been able to implement it consistently because funding uncertainty and contractual arrangements often make long-term planning difficult.

The Cornish model appears to demonstrate what becomes possible when delivery, strategy and asset management operate together rather than independently.

The scale of the challenge alone makes the achievement noteworthy.

Cormac manages approximately 7,300 kilometres of roads, thousands of kilometres of footways, cycleways and public rights of way, alongside bridges, drainage assets, coastal infrastructure and road safety systems.

It is one of the largest and most geographically challenging local highway networks in Britain.

Maintaining that network requires more than efficient pothole repairs.

It requires intelligent asset management, rapid operational response and a willingness to embrace innovation.

That innovation extends well beyond maintenance techniques.

Warm-mix asphalt, recycled construction materials, low-carbon binders, drone surveys, digital asset monitoring, solar-powered road safety equipment and biodiversity initiatives have all become part of routine delivery rather than isolated pilot projects.

Crucially, these innovations have not been pursued for publicity.

They have been adopted because they improve efficiency, reduce environmental impact and extend asset life.

This reflects a broader shift taking place across infrastructure.

Increasingly, success is being judged not simply on engineering outputs, but on wider social, environmental and economic outcomes.

Cornwall's highways operation appears to have embraced that philosophy earlier than many.

Its reported £25 million of independently verified social value over two years illustrates how infrastructure investment can generate benefits that extend far beyond the carriageway itself.

Employment, apprenticeships, local supply chains and community resilience have become integral parts of delivery rather than secondary considerations.

Perhaps most importantly, the Teckal structure allows those benefits to remain closely aligned with public priorities.

That is not to suggest the model is universally applicable.

Every authority operates within different financial, political and geographical circumstances.

Urban boroughs face very different challenges from large rural counties.

Some councils have established relationships with private sector contractors that continue to deliver excellent results.

Others simply may not have the scale required to justify a wholly owned delivery organisation.

But that does not diminish the lessons Cornwall offers.

The industry's debate has often been framed as a choice between traditional outsourcing and wholly in-house delivery.

The Teckal model demonstrates there may be another route—one that combines public ownership, commercial discipline and operational flexibility.

In many respects, it represents a hybrid approach that seeks to capture the strengths of both.

At a time when local authorities are under increasing pressure to demonstrate value for money, resilience and environmental responsibility, that balance deserves serious attention.

None of this removes the need for sustained government investment.

The ALARM report makes clear that no delivery model, however efficient, can eliminate decades of underinvestment.

Funding certainty remains essential if authorities are to move decisively away from reactive maintenance towards genuine asset preservation.

But how that funding is deployed is becoming just as important as the amount available.

If councils are to maximise every pound invested, delivery structures themselves need scrutiny.

Cornwall suggests that organisational reform can be just as powerful as engineering innovation.

As ministers continue to explore new approaches to infrastructure investment, procurement reform and local government funding, examples such as this deserve careful examination.

The future of Britain's highways will not be secured by larger maintenance budgets alone.

It will depend on creating delivery models capable of protecting assets over decades rather than electoral cycles, encouraging innovation without sacrificing accountability, and ensuring public investment generates lasting public value.

Cornwall's experience suggests that is possible.

The question now is whether other authorities—and central government—are prepared to learn from it.
