Urban Tunnels

The world's great cities are constantly called upon to create new traffic arteries and links. It's good when you can trust a partner, who's an underground expert with a reputation for bringing flexibility to every design.


It's for good reason that our engineering office can look back on an enormous scope of pioneering works in the field of urban tunnelling. It has always been our strongpoint to be able to transfer our experience with Alpine tunnels to inner city tunnel projects.
