Investigators have concluded that faulty wiring was the primary cause behind the collision of the cargo ship Dali and the Francis Scott Key Bridge in Baltimore. The incident, which occurred on March 26, 2024, led to the tragic deaths of six highway workers. The findings were released by the United States National Transportation Safety Board (NTSB) after an extensive investigation.
Details of the Accident
The Dali, a 300-meter (984-foot) container ship, experienced two significant power outages due to wiring issues. These blackouts resulted in the loss of control over the ship’s propulsion and steering systems. Consequently, the vessel crashed into the bridge, which collapsed partially during the incident.
Casualties and Immediate Response
- Six highway workers lost their lives in the accident.
- Seven workers were on the bridge when the collision occurred.
- Local authorities swiftly halted traffic across the bridge, thanks to prompt notifications from the Dali’s crew.
Investigation Findings
NTSB Chairwoman Jennifer Homendy remarked on the complexity of the investigation, comparing the challenge of locating the faulty wiring to searching for a loose rivet on the Eiffel Tower. The ship’s electrical issues made it impossible for the crew to maneuver away from the bridge.
Impact and Future Plans
The collision resulted in a global media frenzy, with a livestream capturing the dramatic collapse of the bridge. The shipping channel was reopened in June 2025; however, the Francis Scott Key Bridge is projected to remain closed until 2030. Repair costs are estimated between $4.3 billion and $5.2 billion, according to CBS News.
