The government’s decision to cut £428 million from the RIS3 roads programme threatens to halt progress on two major schemes: the A38 Derby Junctions and the A46 Newark Bypass. Contractors are urging ministers to avoid scrapping these projects outright and instead keep them ‘warm’ in the pipeline.
What ‘keeping warm’ means for road schemes
‘Keeping warm’ refers to maintaining earlier design, assessment and planning work on a scheme after it has been removed from active funding lists. This keeps the project viable for future funding rounds, reducing the time and expense involved in restarting.
Road schemes in the UK undergo extensive preparation before construction begins. Losing momentum by cancelling schemes can mean losing design work and skilled personnel, which forces planners back to square one when projects resume. This risks delays for drivers and higher costs for the public sector.
The impact of RIS3 cuts on the A38 and A46
The Civil Engineering Contractors Association (CECA) highlights that these cuts are part of wider funding pressure linked to the government’s Defence Investment Plan, alongside a further proposed 2% cut across other capital budgets. CECA accepts the need to prioritise funding but warns that full cancellation wastes the benefits these junction upgrades were intended to deliver.
Both the A38 Derby Junctions and A46 Newark Bypass schemes were developed to ease traffic congestion and support economic growth. Cancelled outright, the schemes will need to rebuild momentum from scratch if revived, increasing costs and prolonging traffic issues.
The roads pipeline and its wider importance
For contractors and local authorities, the roads programme pipeline determines staffing and design resources. Abrupt cuts cause knock-on effects in the supply chain and disrupt long-term planning. CECA stresses that ‘keeping warm’ schemes preserves continuity, allowing for quicker responses as funding conditions evolve.
Traffic levels and junction complexities do not diminish due to budget changes. The A38 and A46 cases demonstrate why removing a scheme from the pipeline is not the same as removing the need for it.
Beyond RIS3: funding and future planning
CECA also calls for a renewed debate on road-user charging and vehicle taxation to unlock private investment for roads infrastructure. This reflects broader uncertainty around long-term funding and strategic planning.
The organisation has asked National Highways to collaborate with contractors to find efficiency savings that avoid damaging delivery. It has further urged protection for the RIS4 pipeline and strategic studies to prevent a repeat of stop-start workloads disrupting the sector.
Similar pressures affect local road budgets, with schemes delayed or deferred as councils manage tighter finances. The challenge remains to avoid losing value in work already completed when projects are postponed.
Why ‘kept warm’ matters more than the cut
Ultimately, the question is about reducing waste. If a scheme cannot advance now, preserving earlier work makes a future restart faster and cheaper. This approach is less visible than delivering new bypasses but crucial for maintaining progress.
Motorists may not hear about development pipelines or ‘warm’ schemes, but they will notice whether schemes like the A38 Derby Junctions and A46 Newark Bypass return with momentum intact or fade away completely.
