The motorway section Draženci–Gruškovje international border crossing represents the missing part of the A4 motorway between Slivnica and the border with the Republic of Croatia in Gruškovje.
The initial part of the alignment to the confluence of the Polskava and Dravinja rivers is bound by the course of the terrace levelling of the Maribor–Ptuj depression of a huge Plio-Quarternary tectonic unit, filled whit the Drava gravel stones. Once it crosses the Dravinja River, where the Drava gravel stones disappear, the alignment is bound by the Rogatnica and Maceljčica valleys. These valleys are cut into the Haloze and Pletovarje–Macelj anticlinal. The Haloze anticlinal to the south is composed of Middle Miocene clastites. Further down the alignment to the Gruškovje border crossing, Lower Miocene clastites are present.
Geological and geomechanical analyses were carried out in the framework of project documentation preparation. The results obtained served as a basis for the preparation of geological models of the soil and geomechanical characteristics were determined, which served as a basis for geomechanical calculations for the bridging buildings and supporting walls on the motorway.
