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.
Due to an advantageous layout of tunnel portal and tunnel excavator is was possible to do without shunting bays and laborious shunting during the construction of the single-track railway tunnel.
A double-lane motorway tunnel with a length of approx. 3 km forms part of the new motorway section of ‚Route du Nord' in the biggest infrastructure project in Luxembourg. The two tubes were carried out with an incline of nearly 5%.
