In mid-June Tunnel Boring Machine Ellie broke through into a cavern 40 m beneath Stepney Green, in the East End of London. The breakthrough marked the structural completion of tunnels for Crossrail’s north east spur, between Whitechapel and Pudding Mill Lane. According to Andrew Wolstenholme, Crossrail Chief Executive, over 80 per cent of the new rail tunnels for Europe’s largest infrastructure project had been completed with the breakthrough at Stepney Green. Roughly one month later another two percentage points were added to this quota, when Crossrail announced at the end of July that the last of 250 000 concrete segments, used to line the tunnels of Europe’s largest infrastructure project had been manufactured.
