E-75 Highway belongs to the European Road Network. Both stretchs where Azvi is working are located in Serbia. The section is 6.1 km long and has a final budget of 223 million euros. The works were carried out in the Grdelica Gorge which is formed from the accumulation of ancestral materials prone to landslides. The Juzna-Morava river also runs through the valley. The project encompassed a wide range of well synchronised actions which reflect the technological challenge faced: local and national roads, highways, prestressed girder bridges, overpasses, galleries, concrete, gabion, and reinforced soil walls, slope retention and stabilisation, stream and river regulations, power lines and environmental integration measures as well as the complete construction of this section of the E-75. This dual highway has two 3.5 m lanes in each direction, 2.7 m outer and 0.35 m inner verges. The central reservation is 4m wide. The stretch is 5.8 km in length with two 11 m wide separated carriageways, composed of two 3.75 lanes, a 2.5 m shoulder and two 0.5 m accesible berms. The budget is €51 M. The project includes the construction of 5 bridges and an overpass interchange. The most relevant structures are the viaduct over the river Vrla (644 m long) and the Dzemin Do viaduct (514 m). Both precast T beam viaducts have high piers, 44 m long spans and a 13 m wide deck. Significant environmental protection measures will be applied, including waterway protection and restoration and the construction of noise barriers. E-75 Highway Lots 1 and 6
