The construction of the 700m Burton Green Tunnel for the HS2 project has achieved significant progress, reaching the halfway milestone.
- The innovative ‘top down’ construction method is being utilised to build the tunnel, starting with the side walls and roof before excavation.
- Upon completion, the tunnel will support the passage of HS2 trains through Burton Green, while also restoring the Kenilworth Greenway.
- Beyond Burton Green, similar projects are underway at locations including Copthall, Wendover, Chipping Warden, and Greatworth.
- Completion is expected by autumn 2026, heralding a major advancement in the UK’s high-speed rail infrastructure.
The Burton Green Tunnel, part of the expansive HS2 project, has reached a noteworthy halfway point in its construction. This 700-metre tunnel is being developed by the BBV consortium, which is employing an innovative ‘top down’ construction technique. This approach involves constructing the tunnel’s side walls and roof at the surface level before excavating the tunnel itself, a method that advances both speed and safety in the construction process.
Successful completion of the southern portal entrance, along with other integral structural components such as over 1,300 piles, marks this significant progress. Engineers from the Mott MacDonald Systra design joint venture continue to advance this complex project, which utilises over 33,000 cubic metres of concrete. The construction team, comprising 150 skilled individuals, now turns its efforts to the next phase, which focuses on further excavation and installation of structural elements. Completion remains on track for autumn 2026.
An important aspect of the project is its impact and integration with the Kenilworth Greenway, a popular route connecting Balsall Common to Kenilworth. During construction, a temporary route ensures continued accessibility for the local community, and plans are in place to restore the Greenway close to its original path post-construction. This demonstrates a commitment to maintaining ecological connectivity and community access.
Beyond the Burton Green Tunnel, HS2 works in the West Midlands region are progressing, with foundational works commencing for Birmingham Curzon Street Station and a new bridge under the A38 near Lichfield. Collectively, these developments are critical components of the broader UK high-speed rail network, which aims to significantly enhance connectivity across the region.
According to HS2 Ltd senior project manager Doug Barnett, reaching the halfway mark is a testament to the expertise and dedication of the team, from engineers to support staff. “Delivering a complex structure of this scale requires a huge amount of expertise and energy,” he emphasised. Rupert Blake from BBV echoed these sentiments, noting the project’s rewarding nature and its unique ‘green’ features designed to blend seamlessly into the existing landscape.
The halfway completion of the Burton Green Tunnel marks a crucial phase in the HS2 project, reflecting significant advancement in high-speed rail infrastructure.
