    The problems and achievements on the design and construction of prestressed concrete bridges in Ethiopia is assessed through distributing Questionnaires to be filled by professionals currently working on design and construction of bridges. A seminar is also organized to collect ideas from the participants and also to convey the basic concepts of prestressed concrete bridge design and construction. The basic concepts, principles and advantages of prestressed concrete bridge design are discussed. The different construction methods of prestressed concrete bridges with the detail of anchorages are included. Design example based on simple procedures is shown including its cost comparison with normally reinforced concrete bridge. Standard sections are prepared based on PCI (prestressed Concrete Institute) for different simply supported spans with design flow chart.
