In the future, there should be a construction of bypasses for the residential areas of Rosice and Tetčice. The bypasses should be, according to the area planning, connected to road I/23 in the place of the existing T-junction of this road and road II/394, located to the east of the city Rosice. This connection will require the changing of the exisisting junction solutions. The thesis deals with the choice of the appropriate type of junctions and mainly contains the study of this designed interchange junction.
