The contract includes the construction of the main section over a length of approx. 2,650 metres across an area previously used as farmland, the construction of an infiltration basin system with an upstream sedimentation basin, the early construction of the driving ramp of the second construction phase as well as the associated ballast fill and finally the construction of four amphibian tunnels.
The main focus of this project is on the aspect of "recycling": the soil mass produced in the cutting area will be used to construct the first road embankment of the junction as well as the associated ballast fill in order to consolidate the backfilled gravel pit below the embankment. In addition, the gravel will be sold to the concrete industry to be used as aggregate for new concrete. This will conserve landfill space and promote the reuse of the soil as a building material.
