HS📣 HS2 celebrates final Birmingham tunnel breakthrough 📣
Our giant tunnelling machine digging the 3.5-mile-long Bromford tunnel broke through this morning at the west portal in Washwood Heath, east Birmingham.
The machine – named Elizabeth – was launched 19 months ago, near the Warwickshire village of Water Orton.
This latest milestone means our eight tunnel boring machines have now finished excavating the 23 miles of twin-bore tunnel between London’s Old Oak Common and Birmingham Curzon Street.
The focus is now on the internal concrete work, ventilation shafts and cross passages.
