The goal of the bachelor`s thesis is to design and rationalize a bypass of the road SI/23, which will divert transit traffic from Rosice. The town is situated approximately 25 kilometres west of Brno, in the South Moravian region. The assigned task is to work out a case study that deals with the routing and height solution of the bypass, which shall connect to the existing road SI/23 this way: in the west - between the village Zástávka and the town Rosice, in the east - in the area of the intersection with the road II/394. The route should be designed to make best possible use of the space reserve allotted in the local development plan and also to minimise the construction expenses as well as its environmental impact
