Tunnels under study

The red pages describe future tunnel projects, still in the study phase and early engineering stages of development or even just proposals. This section gives a precise idea of what’s up next. It is often an opportunity for companies to be aware of new projects never or hardly heard of before to approach and advise the owners and developers. As many technical details as possible are given about tunnels and underground structures described. The articles are often illustrated with maps and studded with click-through web links.
