6 km railway tunnel from Stuttgart central railway station to Bad Cannstatt as part of the large-scale project „Stuttgart 21“.
While investigating on the trail of the beginnings of the universe – in the nuclear research centre CERN the quarks go to the racecourse. The tunnels and caverns for the biggest machine in the world were built by Wayss & Freytag Ingenieurbau.
The approx. 2 km long „Stafelter Berg“ Tunnel, north of Luxembourg city is part of the new motorway section of ‚Route du Nord‘ and consists of two double-lane tubes. The tunnel drive was carried out conventionally and with the drill and blast method.
