Bridge Engineering

Bridge Engineering is a specialized discipline within civil engineering focused on the entire lifecycle of bridges, from initial planning and design to construction, inspection, maintenance, and rehabilitation. It involves the application of structural analysis, geotechnical engineering, and materials science to create safe, durable, and efficient structures that span physical obstacles such as rivers, valleys, or roadways. Bridge engineers are responsible for ensuring these vital transportation links can withstand traffic loads, environmental forces like wind and earthquakes, and the effects of time, all while considering economic feasibility and aesthetic appeal.
