Breakthrough for Toulon tunnel

30 April 2011 - New contracts - France

After 44 months of drilling from the west and 27 months from the east, on 3 March 2011 the working faces of the two drives creating the second tube of the Toulon tunnel (south of France) met up at a depth of 35 m.

This 2.8 km-long structure (1.8 km of it tunnelled) running parallel to the first tube, brought into service in 2002 marks the completion of the project to provide an underground crossing beneath Toulon linking up the A50, A57 and A570 motorways.The civil engineering works are being supplied by a consortium comprising Soletanche Bachy and Soletanche Bachy Tunnels, in collaboration with SolData, all subsidiaries of Soletanche Freyssinet (VINCI Construction).
