Safety technology

The Warnow Tunnel has been planned and constructed in accordance with the latest technology. The systems installed have already proven their effectiveness in similar or equal constructions in other German and European traffic projects. The tunnel is one of the most modern road tunnels in Germany.
We reserve the right to make changes to technical data and designs based on new findings, statutory changes, or similar, without further communication.
