Objective of this paper is to determine the scope of research together with the analysis of spatial, traffic, geotechnical, hydrological, environmental and climatic factors and limitations, as well as selection of the optimal corridor by using the multicriterion optimization for planned highway route Banja Luka – Prijedor – Novi Grad, which is the subject of General design. Length of the introduced variant amounts 74,30 km.
The purpose of the General Design will be to identify possibilities for a motorway construction on the route given in the defined transportation concept of the Republic of Srpska, to define service level on the given motorway in altered conditions in the Republic of Srpska road network, to define environmentally acceptable level of protection of the road and its environment, to propose the most appropriate time schedule for road construction from the aspect of general public interest, to choose the best variant, form a basis for adoption of planning documents and get ready for the next design phase.
The most important traffic benefits from new sections between Banja Luka and Novi Grad are as follows:
Enabling a modern link primarily between the areas of Banja Luka, Prijedor, and Novi Grad and the existing Е-661 motorway at the East, i.e. with the future intersection of two motorways in the Republic of Croatia at the West as well as improving conditions on the road segment in the western parts of the Republic of Srpska,
Improving connections between the western parts of the Republic of Srpska and western Bosnia and Herzegovina with the Banja Luka –Gradiška Motorway, Corridor X and the Banja Luka – Doboj Motorway,
Relieving the burden on the existing network segment and improving conditions for road users corresponding between Banja Luka and Novi Grad.
