Construction of the route of the Cham–Hünenberg bypass between the Teuflibach junction and the Oberbösch junction, including the associated engineering structures (including the Eret overpass, Chnodenwäldli support structure, Gibelfeld bridge, Lorzental bridge 3) and concrete roundabout (Oberbösch junction, Rütiweid junction). Large-scale excavation and pouring work, whereby the excavated material is stabilized and partially processed. Work at external locations (e.g. signalling Eichmattstrasse).

- Gibelfeld bridge: 220 m prestressed box girder

- Lorzentalbrücke 3: 190 m prestressed box girder

- Eret overpass: Double-tensioned prestressed slab beam (14.5/38.5 m) over the A4 motorway

- Chnodenwäldli support structure: 350 m long dissolved bored pile wall

- Three directional boreholes DN400-500, length up to 330 m

- 200,000 m3 excavated material (loose material and rock)

- 97,000 m3 of embankment stabilized

- 58'000 m2 Strassenfläche
