• Massive Tunnel Boring Machine (TBM) in Warwickshire becomes first on the HS2 project to complete its full journey underground
• The first bore of the one-mile tunnel under Long Itchington Wood has been dug in seven months

HS2 Ltd is celebrating the very first tunnelling breakthrough on Europe’s largest infrastructure project. A 2,000-tonne TBM named ‘Dorothy’ – after Dorothy Hodgkin, who in 1964 became the first British woman to win the Nobel Prize in Chemistry – has completed its one-mile dig under Long Itchington Wood in Warwickshire.

The giant 125m long TBM, which started its journey at the tunnel’s North Portal in December 2021, broke through the wall of the reception box at the South Portal site on Friday 22 July. Nearly 400 people working for HS2’s main works civils contractor Balfour Beatty VINCI (BBV JV) have delivered this important milestone on the HS2 project. The expert tunnelling team have been working around the clock in shifts for seven months to operate the TBM, which has put 790 concrete rings in place, with each ring made from eight two-metre-long segments. The tunnel preserves the ancient woodland above, which is classified as a Site of Special Scientific Interest (SSSI) and has complex ecosystems that have taken hundreds of years to establish.

HS2 Ltd’s CEO Mark Thurston said: “This is a historic moment for the HS2 project, and I’d like to congratulate everyone involved in delivering it. The 400-strong team, including tunnelling engineers, TBM operators and the construction workers at both portal sites, have pulled out all the stops to achieve this fantastic milestone. This milestone demonstrates the significant momentum behind Britain’s new zero-carbon railway, creating thousands of jobs and apprenticeships, along with hundreds of opportunities for businesses right across the country, helping fuel our economic recovery.”

Celebrating the breakthrough with his team, Balfour Beatty VINCI’s Managing Director, Michael Dyke, said: “This is a momentous moment, not only for Balfour Beatty VINCI, but for everyone involved in delivering HS2. Thanks to the hard work and dedication of our team, Dorothy - our cutting-edge Tunnel Boring Machine - has made history, becoming the first to safely and successfully breakthrough along the route. With Dorothy’s journey now concluded, I am looking forward to celebrating even more milestones throughout the rest of the year and beyond, as we continue to help build Europe’s largest infrastructure project.”

Creating both bores of the tunnel, the machine is removing around 250,000 cubic metres of mudstone and soil, which is being transported to the on-site slurry treatment plant where the material is separated out before being reused on embankments and landscaping along the route.

A 254 metres long conveyor at the north portal site, which takes the excavated material over the Grand Union Canal, removes the equivalent of around 30,000 HGVs from local roads, reducing impacts on the local community and cutting carbon. Over the next four months, the cutterhead and front section of the TBM will be dismantled and transferred back to the north portal, while the bulk of the machine will be brought back through the tunnel. It will be reassembled, ready to launch for the second bore of the tunnel.
