30 Second Briefing
Winvic has completed five years of civils and infrastructure works at SEGRO Logistics Park Northampton, delivering a 2.6km Roade village bypass with bridge and roundabouts, major upgrades to M1 Junction 15 under complex traffic management, and extensive earthworks for the strategic rail freight interchange. The SRFI includes a 35-acre rail terminal, a 55,000m² intermodal and HGV slab, and a 170m tunnel shielding trains entering and leaving the terminal. Winvic also built a 2.3 million sq ft distribution centre and a 1.2 million sq ft BREEAM Excellent, EPC A, net-zero-in-construction facility, within a park masterplanned for up to 5 million sq ft and around 7,450 jobs.
Technical Brief
- Intermodal/HGV slab totals 55,000m², split into 38,000m² intermodal hardstanding and 17,000m² HGV area.
- Rail terminal occupies 35 acres, giving substantial footprint for sidings, cranage and container handling equipment.
- The 170 m tunnel physically screens trains entering/exiting the SRFI, mitigating visual, noise and safety interface risks.
- Plot 4’s 1.2 million sq ft facility includes a 1.14 million sq ft ground-floor warehouse plus 333,251 sq ft mezzanine.
- BREEAM Excellent and EPC A ratings were achieved while meeting UK Green Building Council Net Zero in Construction criteria.
- Junction 15 upgrades were delivered under complex, phased traffic management to maintain motorway network resilience and capacity.
- Roade bypass works combined bridge and roundabout construction with significant earthworks to re-route village traffic.
Our Take
With SEGRO Logistics Park Northampton ultimately providing around 5 million sq ft of industrial space and a 35‑acre Strategic Rail Freight Interchange, this scheme positions Northampton alongside Daventry International Rail Freight Terminal—where Winvic is also delivering a 1.3 million sq ft M&S hub—as a core Midlands rail‑served logistics cluster.
The combination of the 2.6 km Roade bypass and direct access at Junction 15 of the M1 signals that local highway authorities are increasingly expecting large UK logistics parks to fund or deliver strategic road upgrades as part of planning consent, rather than relying solely on incremental junction improvements.
Across our infrastructure coverage, Winvic’s repeat work on large logistics and mixed‑use schemes (Leeds build‑to‑rent, Digbeth housing, Weyside Urban Village highways, and now SEGRO Logistics Park Northampton) suggests it is consolidating a niche in complex, multi‑phase projects where transport interfaces and sustainability standards such as those promoted by the UK Green Building Council are central to the brief.
