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.
Accessibility and a steady increase in ridership place new demands on the infrastructure of the city railway station Dortmund. Conversion and extension of the light rail system provide the sustainability safely.
During extension of the Pyhrn motorway, the Gleinalm Tunnel is provided with a second tube. This makes the motorway safer, since there will be no oncoming traffic in the tunnel.
