WE HAVE BREAKTHROUGH: The first of the London tunnels for the Channel Tunnel Rail Link broke through last month when contractor Costain/Skanska/Bachy Soletanche's tunnel boring machine (TBM) broke into a ventilation shaft at Barrington Road in east London. The 7.15m diameter Wirth TBM had completed a 4.7km section of tunnel from Stratford, the first of two tunnels being built between Stratford and Manor Park as part of the project to link the Channel Tunnel to St Pancras station in central London. Its sister tunnel is due to emerge into the same shaft following delays caused by a ground collapse in Stratford in February. The twin-bore tunnels form part of the 19km CTRL Section 2 between St Pancras and Dagenham.
