    Prestressed concrete is ideally suited for the construction of medium- and long span bridges. Solids slab are used for the span ranges of 10 to 20m , while T- beam slab decks are suitable for span in the ranges of 20 to 40m. single or multicell box girder are preferred for larger span of the order of 30 to 70m. Prestressed concrete is ideally suited for long span continuous bridges in which precast box girder of variable depths are used for span exceeding 50m.Prestressed concrete has been widely used throughout the world for simply supported continuous, balanced cantilever, suspension, hammer-head and bridle- chord type in the span range of 20 to 500m. In this project, designs are prepared for prestressed concrete t-beam and deck slab bridge for spans ranging from 15 m to 45 m at an interval of 5 m. In this project, the designs adopted for each span of bridge is presented in tabular formats. Relevant discussions have also been added when and where required to emphasize further into the matter. This in turn will help us conclude the suitability of the given bridge under Class AA Loading. A Microsoft Excel spreadsheet has also been formulated for the ease of designing. Working drawings of the same have been prepared for clarity of understanding.
