Dear Colleagues,

the next STUVA Conference, the international forum for tunnels and infrastructure, is scheduled to take place in the usual manner as an attendance event from November 24 to 26, 2021, at the Messe Karlsruhe (Rheinstetten).

The STUVA Conference represents one of the most important forums for the entire underground sector. With more than 3,800 professionals from over 20 countries at last count, it is one of the world's leading and largest events in the tunnel sector and brings together the entire value chain of the tunnel industry for professional exchange. The traditional festive evening on the first day of the STUVA conference has become an absolute highlight of the event in recent years. You too can meet your business partners in a pleasant atmosphere.

STUVA conferences help to sharpen the view on the future of our industry. This has not changed until today.
