£10M A38 Devon upgrade: work phasing and safety design notes for project teams

30 Second Briefing
More than £10M of National Highways works will start next month on the A38 in Devon, targeting a series of upgrades over the coming months on this key dual carriageway between Exeter and Plymouth. Although detailed scope is not yet published, schemes of this scale on the A38 typically include resurfacing high‑skid‑risk sections, renewing safety barriers and drainage, and strengthening structures at junctions and overbridges. Contractors and designers should expect night-time possessions, lane closures and tight work windows to maintain strategic traffic flows.
Technical Brief
- Delivery is phased “over the coming months”, implying multi-season traffic management and weather‑dependent programming.
- Start date is “next month”, requiring immediate mobilisation, RAMS updates and revised CDM documentation.
- Safety risk assessments must address high-speed dual carriageway working, with strict controls on worker–traffic interface.
- Schemes of this type on the A38 often trigger updated road safety audits and post‑opening monitoring.
- For similar UK trunk road renewals, early coordination with blue‑light services and local authorities is now standard practice.
Our Take
In our database of 938 Infrastructure stories, National Highways features heavily in higher-value schemes such as the £317M M25 Junction 10 upgrade, so a mid-scale Devon A38 package signals continuing spend on secondary strategic routes alongside flagship motorway nodes.
The A38 works in Devon sit alongside other recent National Highways interventions on ageing assets, such as the rapid demolition of a 50‑year‑old bridge at M42 Junction 6, suggesting a programme-level push to tackle life‑expired structures before they trigger unplanned closures.
Compared with complex junction reconfigurations like the expanded M3 Junction 9 scheme near Winchester, this Devon package is likely to be more attractive to regional contractors focused on pavement and viaduct refurbishment rather than major geometric redesign.
