    This document discusses the components, materials, and classifications of bridges. It lists the main parts of a bridge as foundations, abutments, aprons, approaches, decking, bearings, and handrails. Bridges can be made of materials like reinforced concrete, metal, timber, and prestressed concrete. They are classified based on their purpose, materials, span type, joining method, floor position, and ability to provide waterway clearance. The selection of a bridge type considers factors such as traffic volume, river characteristics, material and fund availability, construction time, physical geography, navigation needs, and construction and maintenance facilities. Site selection focuses on suitable foundations, straight approaches, firm banks, minimum stream width, and a
