        abstract = {Prestressed concrete bridges represent a critical advancement in modern bridge engineering, offering superior strength, service life, and economy compared to conventional reinforced concrete structures. This paper investigates the design principles of prestressed concrete bridges with particular emphasis on serviceability and ultimate limit states as defined in contemporary design codes. The study outlines the fundamental behavior of prestressed members under various loading conditions and examines analytical procedures for deflection control, cracking limitation, and ultimate strength assessment. Typical design equations, stress relationships, and prestress loss mechanisms are discussed to establish a comprehensive framework for structural analysis. The interaction between serviceability and ultimate design criteria is analyzed to highlight their combined influence on safety, durability, and material efficiency. The paper concludes that balanced consideration of both limit states ensures optimal structural performance, extending the operational lifespan of bridges while maintaining economic feasibility.},
