Tunnel boring machine Amandine gets to work on the Grand Paris Express project
17 June, 2019
The first machine - Ellen - began tunnelling the 3.9 km stretch from the Parc Robespierre shaft in Bagneux to Fort d'Issy-Vanves-Clamart in mid-February.
Having completed the first 112 metres of tunnel, it is currently at a standstill awaiting the lowering and connection of trailer sections. This work is being carried out by VINCI Construction (VINCI Construction Grands Projets as consortium leader, VINCI Construction France, Dodin Campenon Bernard and Botte Fondations) and Spie Batignolles.
