Abstract: - Bridges are one of the most important components of transportation infrastructure, playing a vital role in ensuring connectivity, economic growth, and social development. In recent years, the increasing demand for efficient, economical, and durable bridge structures has led to significant advancements in bridge design and analysis techniques. This review paper presents a comprehensive study of previously published research works related to the design, analysis, and optimization of bridge structures, with a special focus on minor bridges. A total of 26 research articles have been reviewed, covering various aspects such as structural analysis, optimization techniques, foundation systems, software-based modeling, machine learning applications, and innovative bridge designs. The review highlights those modern techniques such as finite element method (FEM), STAAD Pro, ANSYS, genetic algorithms, and reliability-based design optimization (RBDO) have significantly improved the accuracy and efficiency of bridge design. Additionally, studies on sustainable construction, box-type bridges, and precast methods have contributed to cost-effective solutions. However, it is observed that most research works focus on isolated parameters rather than considering multiple parameters simultaneously. The paper identifies key research gaps such as lack of integrated analysis, limited focus on minor bridges, and insufficient consideration of real-life conditions. The study concludes that there is a need for a comprehensive and optimized approach that considers varying parameters for minor bridge design. This review provides a strong foundation for future research and contributes to the development of efficient, safe, and economical bridge structures.
