Discover the latest issue of the Tunnel Observatory newsletter!

The CETU Tunnel Observatory has just published its 6th newsletter, focusing on railway tunnels in France. These structures are now included in an interactive map, enhancing the visualisation of the infrastructure monitored by the Observatory.

This latest newsletter also provides some news about ongoing works in road tunnels, as well as graphs relating to tunnel boring machines in operation in France.

In order to better meet the expectations of our readers, we invite you to send us your suggestions for indicators or topics to be explored in future editions of these newsletters.
