The rehabilitation includes a comprehensive renewal of both viaducts in the length of 600 m as follows: rehabilitation of the pillars with heads, rehabilitation of edge supports with connection dams, replacement of worn-out beds, rehabilitation works on the concrete of lintel construction, detailed examination and renewal of external cables, expansion of carriageway panels by one meter at least and reinforcement with carbon rods, complete replacement of dilatations, edge rims, all fences, walkable elements in the separation lane, hydroinsulation and asphalt layers, replacement of rainwater drainage system and transfer of all utility lines to new cable shelves. During the reconstruction in Slovenia, we introduced the novelties for optimizing a more

We set up an entire permanent monitoring system that controls the behavior of viaducts during traffic load.
