Limitations and possibilities of planning the high-speed roads in the urban environment - spatial plan of the special purpose area of the infrastructure corridor high-speed road Osružnica-Obrenovac

The Ostružnica-Obrenovac high-speed road was planned and designed in order to connect the central area of the city of Belgrade and the Obrenovac municipality, i.e. i.e. the highways A2 ("Miloš Veliki") and A1 (Belgrade's southern ring road). For the purposes of creating the Spatial Plan, a preliminary technical solutions for the road route for basic calculated speed of 80-100 km/h, as well as for the part of the Sava Riverbed, were prepared. The main challenge of the simultaneous preparation of elements of the conceptual technical design and the Spatial Plan was the definition of the route, the determination of the road corridor and the connection with the surraoundings, in an urban area, with significant natural limitations. The paper analyzed the basic limitations and planning solutions for each of the three sections of the high-speed road. Special emphasis in the work refers to the planning of a high-speed road through landslide zones, the water land of the Sava River, and the existing industrial zone of Barič. Conflicts and ways of their relativization through planning solutions, regimes of space use and measures are pointed out. Through the concluding remarks, a comment on the sustainability of the project and its implementation framework was given.
