30 Second Briefing
Road renewals on England’s 4,500‑mile strategic road network will receive £8.4bn under the Department for Transport’s £27bn third roads investment strategy (RIS3), which allocates £24.9bn to operate, maintain, renew and enhance the network over the next five years. The package includes £1.65bn for publicly funded works on the Lower Thames Crossing and £402m ringfenced for inward investment projects, with schemes now mapped in a new interactive planning tool. Major enhancements starting in RIS3 include dualling remaining A66 Northern Trans‑Pennine sections plus junction upgrades at Penrith and Scotch Corner, A38 Derby junctions, the A46 Newark bypass, the M54–M6 link road and the M60/M62/M66 Simister Island interchange.
Technical Brief
- £8.4bn renewals budget targets the 4,500‑mile strategic road network’s ageing pavement and structures.
- National Highways is mandated to “tackle an ageing network head‑on” with focused renewal programmes.
- Publicly funded Lower Thames Crossing works receive £1.65bn, covering enabling and associated highway interfaces.
- A66 Northern Trans‑Pennine scheme upgrades residual single carriageway sections to dual, plus Penrith/Scotch Corner junction remodelling.
- Traffic relief for the “overused” M62 is a stated objective of the A66 capacity enhancements.
- Additional RIS3 starts include A38 Derby junctions, A46 Newark bypass, M54–M6 link road and Simister Island upgrades.
- Concentrated renewals funding is intended to give contractors and suppliers multi‑year workload visibility for planning plant, labour and materials.
Our Take
The Department for Transport features heavily across recent coverage, from the North Hykeham relief road funding release (Feb 2026) to the NAO’s concerns over Northern Powerhouse Rail, signalling that RIS3’s £27bn over five years will be competing with a crowded pipeline of nationally significant schemes for delivery capacity and political attention.
With local schemes such as the Shrewsbury North West Relief Road facing cancellation on affordability grounds, the ringfenced renewals and enhancement spend under RIS3 is likely to pull design and construction talent towards the strategic network and away from more marginal council-led road projects in the UK regions named in this package.
