    Hethel spine road: design, access and development notes for infrastructure teams

    Hethel spine road: design, access and development notes for infrastructure teams

    First reported on The Construction Index

    30 Second Briefing

    Construction of the £8.4m Hethel spine road has started in South Norfolk, with Jackson Civil Engineering moving from preliminary works into main construction, including a new roundabout giving direct access to an expanded employment zone beside the Lotus Cars factory. The scheme will unlock 20 hectares of development land owned by Hethel Enterprises, allocated in the Greater Norwich Local Development Plan for engineering and technology businesses. Delivered jointly by South Norfolk Council and Norfolk County Council, the road is intended to support growth of the Hethel Engineering Centre and co-located start-ups.

    Technical Brief

    • Land to be unlocked totals 20 hectares, all in single ownership under Hethel Enterprises.
    • Scheme is embedded in the Greater Norwich Local Development Plan, giving planning certainty for subsequent plots.
    • Delivery is structured as a joint client arrangement between South Norfolk Council and Norfolk County Council.
    • For similar enterprise-zone schemes, early spine-road delivery often de-risks later plot-specific access works.

    Our Take

    At £8.4m to unlock 20ha, the implied enabling cost per hectare is relatively low compared with other UK business-park road schemes in our database, which should help South Norfolk Council and Norfolk County Council justify the scheme on value-for-money grounds.

    Because the land is already allocated in the Greater Norwich Local Development Plan, the Hethel spine road effectively converts ‘paper’ employment land into deliverable plots, which tends to shorten lead times for incoming occupiers around the Lotus factory and Hethel Engineering Centre.

    Within our 727 Infrastructure stories, relatively few pieces involve targeted access roads for single anchor manufacturers like Lotus Cars, signalling that this is a more bespoke, cluster-building intervention than typical distributor-road or bypass projects.

    Strabag’s Pfaffensteig Tunnel contract: design and delivery notes for rail engineers

    Strabag and Group company Züblin have secured the design-and-build structural works for the ABS Gäubahn Nord/Pfaffensteig Tunnel in south-west Germany, centred on an 11km twin-bore rail tunnel linking Stuttgart Airport station directly to the Gäubahn line towards Switzerland. About 9.8km will be driven by two TBMs, with conventional tunnelling for the A8 motorway undercrossing and airport connection, plus a 240m cut-and-cover section, retaining structures, railway underpasses and a grade-separated crossing. A 3km surface section will be upgraded and partially realigned for 200km/h operation, delivered under an integrated project delivery model with Ed. Züblin, Wayss & Freytag and Strabag AG sharing tunnelling, structural and earthworks packages.

    National Grid TBM under the Thames: tunnelling design and risk notes for engineers

    A 271.5‑tonne Herrenknecht Mixshield TBM, Caroline, has started driving a 2.2km electricity cable tunnel with a 4m internal diameter beneath the River Thames in Essex for National Grid’s Grain to Tilbury project, delivered by the Ferrovial BEMO joint venture. The drive will pass through variable Thames estuary ground conditions between 35m‑deep launch and reception shafts of 15m and 12m diameter, with tunnelling continuing into 2026 and overall scheme completion targeted for 2029. The new tunnel will replace the 1969 Thames Cable Tunnel and carry new high‑voltage circuits between Grain and Tilbury substations.

    Panama Canal Mixshield undercrossing: design and tunnelling lessons for engineers

    A 13.46m diameter Herrenknecht Mixshield TBM has broken through into the future Balboa station on Panama Metro Line 3 after completing the first-ever TBM undercrossing of the Panama Canal at depths exceeding 60m below sea level. The 5,600kW, 26,616kNm machine, fitted with an accessible cutterhead and more than 4,500 sensors linked via the Herrenknecht.Connected platform, has achieved peak advance of 150 segment rings (about 300m) per month through mixed sandstone, tuff, breccias and basalt. Around 1.5km of the 4.5km twin-track tunnel remains to final breakthrough.
