Bridge demolition involves the careful dismantling or removal of a bridge structure, typically carried out for reasons such as reconstruction, replacement, or urban development. Before demolition begins, thorough planning is conducted to assess the bridge's condition, identify any hazardous materials, and select the most suitable demolition method. Hazardous materials, if present, are safely removed, and utilities are disconnected. The chosen demolition method, which may involve mechanical means or controlled explosives, is executed with a focus on safety, efficiency, and minimizing disruption to surrounding areas. Debris generated during demolition is removed and disposed of responsibly, with salvageable materials sorted for recycling.
