Which federal agency mandates bridge safety inspections in the United States?

The Federal Highway Administration (FHWA) is the federal agency responsible for mandating safety inspections for bridges across the United States. Established to ensure safe and efficient transportation systems, the FHWA oversees the implementation of standards and regulations that govern bridge inspections. The agency requires states to develop and maintain inspection programs for all in-service bridges, emphasizing the importance of assessing structural health and safety to prevent accidents and maintain public confidence in the transportation infrastructure.

This regulatory framework is crucial for identifying any deficiencies in bridge conditions and for prioritizing maintenance and repairs. The FHWA’s guidelines and standards, including the National Bridge Inspection Standards (NBIS), ensure consistency and thoroughness in inspections nationwide, providing a systematic approach that enhances the safety and functionality of the nation's bridges.

The other options, while related to transportation or safety, do not hold jurisdiction over the federal mandates concerning bridge inspections.
