Beneath the central business center of southwest France, ARCADIS is working on an impressive project. In the densely populated city center of Toulouse, the subway network will undergo a 9-mile north-south extension, with 20 station stops.

ARCADIS prepared the detailed design for many of the stations, controlled the tunnel design and provided consulting services for the tunnel boring. ARCADIS applied various tunneling techniques based on the geotechnical conditions. Construction beneath the famous Canal du Midi – a Unesco World Heritage listed site – required an innovative approach. When completed, the new subway line will cross the existing east-west subway line in the heart of the city center, providing access for travel in all directions.
