The investigation is ongoing into the circumstances that caused the barge to strike the bridge. Coast Guard and NTSB investigators are working together to gather and analyze evidence to determine the factors that led to the incident and if acts of misconduct, incompetence, negligence, or violations of federal law were committed. Once the investigation is complete, both agencies will issue independent reports detailing their findings.
