HS2 developments around the Chalfonts villages have made significant progress as of late, with ventilation shafts and passageways being excavated, and tunnelling efforts reaching their halfway point.
The development’s two 2,000 tonne machines, nicknamed ‘Florence’ and ‘Cecilia’, have been digging their way underneath the Chilterns for 18 months, and have now managed to cross the five-mile mark of their tunnel.
Five shafts that will provide ventilation and emergency access to the project have also been excavated, with them being locate in Chalfont St Peter, Chalfont St Giles, Amersham, Little Missenden and Chesham Road.
The first breakthrough for a cross passageway to the Chalfont St Peter has also recently taken place, with workers now able to begin forming the tunnel it will run through.
Martyn Noak, HS2’s head of tunnel engineering, said: “It’s great to be able to celebrate the half-way point of this 10-mile-long tunnel.
“The whole team has put in a fantastic effort over the last year-and-a-half, and I’d like to congratulate the crews of both Florence and Cecilia for passing this important tunnelling milestone and thank them for all their hard work.”
“This tunnel will take HS2 underneath the Chiltern hills, safeguarding the woodlands and wildlife habits above ground as well as significantly reducing disruption to communities during construction and operation.”
