Construction of a 1,650m tunnel and a 200ml covered section
The Stafelter tunnel, which connects the Waldhaff interchange in the south and to the Heeschdrëfferbierg plateau in the north, consists of two two-lane tubes.
Its underground length is 1,850m, including 1,650m of tunnel and 200m of covered section.
The Stafelter tunnel connects the Waldhaff interchange in the south with the Heeschdrëfferbierg plateau in the north.

Works carried out
Félix Giorgetti was responsible for the following:
- Platforms for site installation;
- Earthworks for the north and south entrances and the covered section;
- Road works outside and inside the tunnel;
- Arrangement of tunnel heads.
The 1,650m were excavated from the only southern portal with staggered excavations on both fronts.
The Stafelter Tunnel has a horseshoe profile and was dug according to the principles of the Austrian N.A.T.M. method. This method was developed during the years 1957-1965 and the general idea is to use the intact rock around the tunnel to stabilise the structure.
Motorway tunnel – two tubes, with 2 or 3 lanes, in the shape of a horseshoe.
Covered section in the north consisting of 2 tubes
Galleries at a distance of 270 m each
Emergency bays at a distance of 90 m each
Excavation profile for the horseshoe section
72.39 to 76.15m²
South gate: excavation
North gate: excavation
Covered section in the north: excavation
With a length of 4,000 metres and a width of 60 metres, the runway is renovated in sections and only at night.
Félix Giorgetti, in a consortium with Karp-Kneip Constructions, built for lux-Airport a new checkpoint as part of the rehabilitation work on the Findel runway.
Rangwee Tunnel II
Félix Giorgetti built a second tunnel alongside the existing Rangwee tunnel.
