A bridge collapse occurs when a bridge fails to support its intended load, leading to a sudden and often catastrophic failure. This can happen due to various factors, including structural weaknesses, poor maintenance, natural disasters, or excessive weight. When a bridge collapses, it can result in significant damage, injuries, or even fatalities. Investigations into bridge collapses typically involve examining the design, materials, and construction practices used. Engineers and safety officials assess the condition of the bridge and may implement measures to prevent future incidents. Regular inspections and maintenance are crucial for ensuring the safety of structures like bridges.
