Design and construction of Banja Luka – Doboj Motorway, Section Banja Luka – Prnjavor (km 0+000 to km 35+300) Contract no. RS/EIB-2012/W

Investor: Public company “Republic of Srpska Motorways“

Value of works: 184,9 m EUR (361,6m BAM)

Broader context of the project:
The existing main road M16.1 from Banja Luka to Doboj, via Derventa, plays a very important role in the European long-distance transportation system.
