There are two footpaths, 1.10 m wide each, on both sides of 11.50 meters wide carriageway, so the overall width of the bridge is 14.20 m. Cross-section consists of four pre-stressed girders with the height of 1.80 m and weight of 38 t each.

The second largest bridge is marked as the Bridge 10. It consists of two independent continuous structures, 180 m and 225 m long, interconnected by an expansion joint. Continuous structures consist of four longitudinal girders connected by the bridge deck and cross girders over supporters and within spans. Longitudinal girders have constant height of 2.75 m and weight of 128 t.

The Bridge 11 is continuous girder which consists of four spans, 98 m long, with the pavement resolved as reinforced concrete bridge deck, h=1.30m, with hollow core and pipes made of Styrofoam, Ø90cm of full section (There are 9 pieces on cross-section of the bridge deck). The bridge deck is cast in situ on falsework made of nine temporary supports.

The Bridge 12 is a bridge – viaduct bridging the valley and it is resolved as a chain of simply supported interconnected prefabricated and pre-stressed girders with a span of 25.0 m, with three spans for all four bridges.

The Bridge 24 has a similar construction project, which is a set of four parallel bridges at the intersection “Orlovaca”, with the overall span of 71.10m.
