This project presents the design and analysis of a proposed bowstring bridge connecting Gothuruth to Chathedom across the Periyar River in Kerala. Aimed at enhancing connectivity and regional development, the bridge spans 580 meters with an 11-meter-wide carriageway and 1.2-meter pedestrian paths on both sides. Finite element analysis was used to evaluate structural performance under various load combinations, including wind and seismic forces. The design incorporates high-strength concrete for piers and prestressed steel cables for the arch, ensuring strength and durability. The structure is designed to withstand wind speeds up to 200 km/h and has an estimated lifespan of 50 years. Environmental impact assessments confirm minimal disruption to river flow and aquatic life. Overall, the project offers a sustainable, resilient, and efficient solution for river-crossing infrastructure.
