On Tuesday 27th February, HS2’s Tunnel Boring Machine named Florence achieved an historic breakthrough near South Heath, Buckinghamshire. After an almost three-year journey of 10 miles underneath the Chiltern hills, the enormous 2,000-tonne machine finally broke through into the light of day at 11am, to a reception committee of several hundred HS2 workers, the press and other VIPs…. all guarded by two MistCannon Rovers providing dust suppression coverage for the event!
