The aim of the diploma thesis is to propose a modification of the road I / 52 between the junction with the D1 motorway and Rajhrad on the D52 motorway in a way that a continuous highway can be created without the need to create an alternative route over the southern tangent in route Wien-Prague and D2 and also to design routes for transport which cannot enter the highway. The other aim is to define the problem elements and create a variant solution.
