              Investor: Public Company "Republic of Srpska Motorways"

              Designer: TZI-Inženjering d.o.o. Sarajevo


A brief description and TZI-Inženjering services :


                      By the realization of the motorway connection of Banja Luka and Doboj as an Investment priority Project,
                      significant improvements of the traffic capacity and level of services would be achieved on segments
                      which are connecting Corridors Xc (E 661) and Vc (TEM).The initial chainage of the motorway section is placed
                      behind the interregional interchange Mahovljani 1, and the end chainage is at the connection of the existing
                      main route M17 ( interregional interchange Johovac 2), (section Šešlije-Doboj), in the zone of populated places
                      Johovac and Rudanka. The motorway section covers three interchanges Mahovaljni 2, Prnjavor and Johovac 1, a
                      "T" Type interchange with a toll station.The base of the project documentation were preliminary design
                      (made by IGH Institute 2009.) and a geodetic survey made for the purpose of making the main design.

The Project documentation is formed out of the following groups:

                      A Main Route - Section Prnjavor-Dobojl=36 km

                      B Interchanges Interchange Prnjavor i Johovac 1

                      C Roads out of main route l=20,4 km

                      G geomechanics

                      H Drainage, water protection and watercourse regulations - outter and inner drainage including 43 culverts

                      I Installations

                      O Objects - 52 objects including Bridge Bosna l=418m

                      P Traffic signalization and equipment

                      V Toll station, traffic control, and maintenance center, roadside servise facility


                      Objects at this motorway section are designed according to geomorphological and hydrological conditions.
                      On this section smaller bridges (spans up to 15m) are dominating which are design as box shaped RC structures.
