The aim of this bachelor thesis is to design a monorail concrete bridge. Focus will be put to design several preliminary versions of a girder bridge. There will be chosen one variant which will be examined more. I will make an assessment and comparison of this variant from concrete and prestressed concrete. As a result of this assessment I will choose the variant which is more convenient and make drawings documentation. The bridge is situated nearby city of Velké Pavlovice in the South Moravia. The rail is a monorail number 255 from Hodonín to Zaječí. The bridge goes over the Trkmanka brook. Calculation of inner forces is made in SCIA Engineer 2012 program. Design is made according EC standarts
