The federal road B 317 between Scheifling and Klagenfurt North is to be upgraded to a four-lane motorway
("S 37 Klagenfurt Motorway"). By this, the following improvements are to be achieved:
- a better connection between Carinthia, Upper Styria and Upper Austria with economic impulses for the
districts Klagenfurt City and Greater Klagenfurt;
- an increase of the traffic safety;
- a relieve of the transit traffic for the adjacent villages;
- an improved noise and environment protection.
The section 3 (Mölbling - Klagenfurt North) comprises the most southern part with a route length of 29 km,
13 interchanges, subsurface segments and numerous bridges.

soil mechanics in the preliminary design study and permission phase, including the environmental impact
assessment study.
The processing covers the establishment of the basic information with the planning, supervision and evaluation
of subsoil explorations. Based on these, the expert's reports for the respective fields are compiled.

Waterworks Facility Zwirnawald:
The current project allows for construction measures within the wider ground water protection zone of the
waterworks facility Zwirnawald. For an accordant realization of the project, the valid permission decree for
this facility has to be amended.
As a basis for this, ground water model calculations with unsteady flow were run in reconciliation with the
demands of the authorities. With the help of these calculations, the extent of the catchment area of the
Zwirnawald facility was initially determined for the current operating situation and conclusions concerning
flow time and flow limits were drawn. Subsequently, scenarios have been developed for the operation of the wells,
which serve as a basis for the necessary amendment of the permission decree. This permits the carrying out of the
project according to the planned design
