On 07.11.2013 Crossrail reached another important milestone as 1,000 t TBM Elizabeth broke into Stepney Green Cavern, one of Europe’s largest mined caverns, in the East End of London. Elizabeth, along with her sister machine Victoria, is completing the longest tunnel drive on the Crossrail project, from Limmo Peninsula near Canning Town to Farringdon, a distance of 8.3 km. Elizabeth will now undergo maintenance inside Stepney Green’s westbound cavern before resuming tunnelling towards Whitechapel, Liverpool Street and Farringdon. Yesterday’s breakthrough is the first of four that will take place at Stepney Green. Victoria is due to breakthrough into the site in the next few weeks.
