Groene Hart Tunnel – 2004

Within the framework of extending the Thalys high speed rail line between Rotterdam and Amsterdam, Bouygues Construction constructed the single-tube, two lane, 7 km long Groene Hart tunnel. The digging works required the construction of the largest tunnel borer in the world (nearly 15 m diameter). Located in the protected Dutch “Groene Hart” (“green heart”) zone, the site works had to respect very strict environmental constraints.
