The HS2 Burton Green Tunnel, a key part of the UK's high-speed rail project, has reached an impressive halfway mark in its construction. This 700-meter-long structure is designed as one of HS2's five ‘green tunnels,’ crafted to harmonize with the surrounding landscape in Warwickshire. Once completed, it will carry high-speed trains beneath the village of Burton Green and feature a green space on top, restoring the Kenilworth Greenway, a beloved local path for walkers, cyclists, and horse riders.
A Sustainable Approach to Tunnel Construction
The Burton Green Tunnel employs a ‘top-down’ construction method. This technique involves constructing the tunnel from ground level, beginning with the walls and roof, followed by excavation beneath. This innovative approach allows for controlled excavation while maintaining stability, crucial given the complex nature of tunneling in densely populated areas. Engineers have also recycled excavated soil to landscape around the tunnel, reducing environmental impact and helping the structure blend into the natural scenery once completed.
Milestones and Community Integration
With the southern portal entrance complete and over 1,300 piles laid using 33,000 cubic meters of concrete, the project is on track to finish by Autumn 2026. HS2 has also provided a temporary path for the Kenilworth Greenway during construction, ensuring continuity for community members who rely on this route. Once fully restored atop the tunnel, the Greenway will further enhance the green and recreational space around Burton Green.
