The M26 motorway needs something a bit better than an auger bore, and so they call in the Tunnel Tigers, who push a bore lined with concrete sleeves that prevent any future subsidence.
The Tunnel Tigers in person, Pat Doogan, John Sweeney and Paul Duffy
Paul travels down the tunnel as the skip is winched to the digging face
Pat & Paul attach the crane brothers to lift the spoil back up to Eugene and Shane waiting on the spoil heap.
Meanwhile...... on the other side of the motorway, two excavators are digging an enormous bellhole
The whole digging head slowly emerges into the sunshine.
Gary "The Crane" drops in the empty skip.
John operates the digging arm, pulling spoil back onto the conveyor and into the skip, which is then winched back out again.
A shout from John, and the digging head breaks through into daylight again
