National Bridge Inspection Standards

The National Bridge Inspection Standards (NBIS) are regulations established by the Federal Highway Administration to ensure the safety of bridges in the United States. These standards dictate how often bridges must be inspected, the qualifications of inspectors, and the procedures to evaluate structural integrity and safety. Regular inspections help identify any maintenance needs or potential hazards, ensuring that bridges remain safe for public use. The NBIS plays a crucial role in preventing accidents and prolonging the lifespan of transportation infrastructure.
