24 Oct CONSTRUCTION OF AMPHIBIAN UNDERPASSES IN FULL SWING
In October 2023, the Slovenian Infrastructure Agency (DRSI) and the contractor Trgograd d.o.o. started with the construction of the first underpasses for amphibians in the Podkraj project road section.
In the photos below, you can see how the contractors prepared the terrain.
An AB slab is installed under the underpasses, then stone thresholds are made on the slab, and the soil must be solidified between the thresholds. The stone threshold and soil extend approx. 5 cm above the height of the lower edge of the culvert. The contacts of the elements of the underpasses are protected with bitumen strips 20 cm wide.
After the installation of the underpasses, the arrangement of the road and the installation of guide fences for amphibians will begin. At the same time, access to the land and the installation of amphibian grids will be arranged. When all the work is done and the driving surface is arranged, the Podkraj project section will be ready for asphalting.
