Unlocking construction opportunities around NSIPs

The construction sector continues to benefit from strategic investment in the UK’s Nationally Significant Infrastructure Projects (NSIPs), with a growing body of evidence showing a powerful “halo effect” on surrounding development activity.

As these large-scale schemes take shape, they are not only transforming national transport and connectivity but also catalysing a surge of local and regional construction within a 10-mile radius of each project.

By using Glenigan’s advanced mapping tools, we can easily identify and monitor surrounding projects that have seen activity within the last 60 days, enabling contractors, developers, and suppliers to target high-opportunity areas backed by major public investment.

Mapping opportunities around NSIPs

Glenigan’s tools show a strong correlation between NSIPs and nearby construction activity. Here’s a breakdown of some key schemes and the halo of development forming around them:

Simister Island – M60/M62/M66 Junction Improvements

Glenigan ID: 19342018
Investment: £340M
Surrounding Projects: 698

Located at Junction 18 of the M60, Simister Island is one of the busiest interchanges in the North West, with daily traffic volumes nearing 90,000 vehicles. This scheme focuses on reducing peak-time congestion and journey delays.

The halo impact is substantial: Glenigan’s mapping tool highlights 698 active projects within 10 miles of the junction, revealing a wide array of development driven by enhanced regional connectivity. While the NSIP itself isn’t supporting a single new development directly, its value in enabling growth is reflected in nearby project volume.

A46 Newark Bypass

Glenigan ID: 19342016
Investment: £500M
Surrounding Projects: 76

Funded through the Strategic Road Network 2 initiative, this bypass upgrade aims to improve road reliability and promote regional economic performance. As part of a wider vision to establish a robust trade corridor between the M5 and Humber Ports, the bypass already supports 76 projects with recent updates nearby.

These include mixed-use and commercial developments that will benefit from increased traffic flow and access, particularly important for logistics, distribution, and manufacturing sectors.

M5 Junction 10 Improvements & Golden Valley Development

Glenigan ID: 20170822
Investment: £254M
Surrounding Projects: 149

This scheme will create a new link road and enhance the A4019 Tewkesbury Road to facilitate housing and employment growth in West Cheltenham. A key part of the region’s long-term growth, it also unlocks wider opportunities such as the £2BN Golden Valley Development (Glenigan ID: 19246977), which includes:

• £115M Innovation Centre Phase 1 (Glenigan ID: 24097462)
• £28.8M Innovation Centre Phase 2 (Glenigan ID: 25247010)
• £173.5M Mixed-use Residential and Commercial (Glenigan ID: 23037872)
• £650M Cyber Business Park (Glenigan ID: 17069248)
• £53.6M Residential & Commercial Parcel (Glenigan ID: 24232072)

North West Cheltenham Expansion

Glenigan ID: 16008626
Planned Investment: £1BN

This major development, supported by improved transport links, will deliver up to 4,115 homes, including 35% affordable housing, alongside elderly accommodation, a hotel, retail, business parks, education, and green infrastructure. It’s a clear example of how infrastructure enables long-term, sustainable urban growth.

Conclusion

Glenigan’s mapping tools clearly illustrate the far-reaching impact of Nationally Significant Infrastructure Projects. These investments serve as more than just engineering milestones; they are enablers of local and regional development, unlocking hundreds of surrounding projects and offering a fertile ground for future construction activity.

For stakeholders across the industry, visibility into these halo effects offers a strategic edge, highlighting where to focus effort, investment, and resources to capitalise on emerging opportunities. Request a free demo of Glenigan and our mapping tools to see the opportunity for yourself.
