NTSB Links 2024 Baltimore Bridge Collapse to Faulty Cargo Ship Wire

Baltimore, Nov 19, 2025 — A loose wire on the Dali cargo ship may have initiated the catastrophic 2024 collapse of the Francis Scott Key Bridge, according to a Tuesday report from U.S. authorities. The National Transportation Safety Board (NTSB) stated that this incident, which resulted in six fatalities, was preventable.

The Dali collided with one of the bridge's pillars on March 26, 2024, resulting in the tragic deaths of six construction workers and several vehicles plunging into the frigid Patapsco River. This disaster caused significant disruptions in traffic and shipping at the Port of Baltimore, effectively closing a crucial interstate and leading to extensive economic repercussions.

During the hearing on Tuesday, NTSB investigators revealed that the malfunction of an electrical cable on the Dali caused a sudden power failure that may have diverted the ship off its designated course. "This tragedy should never have occurred; lives were lost that could have been saved," asserted NTSB Chairwoman Jennifer Homendy, emphasizing the preventability of the incident.

Authorities at the bridge had been informed about the ship's deviation from its path but failed to alert the inspector overseeing the construction workers. Investigators noted that had the workers received an alert in time, they might have had approximately one minute and 29 seconds to seek safer areas on the bridge before the impact, a critical window that could have potentially averted the fatalities.

The NTSB’s inquiry revealed several contributing factors, including the electrical failure due to the loose wire, complications with the ship’s fuel pump, and a lack of measures to safeguard the bridge against such incidents. These findings reaffirmed a preliminary report from earlier in 2024, which suggested that electrical failures were likely responsible for the ship's blackout.

The repercussions of the bridge's collapse have been substantial, with initial repair costs estimated at about $1.9 billion and expected completion by 2028. More recent projections indicate costs nearing $5 billion, with reconstruction efforts potentially extending until 2030. Maryland Governor Wes Moore noted that the increasing costs can be attributed to national material price hikes. "Policies out of Washington have raised prices on everything—including vital materials needed for the reconstruction of the Francis Scott Key Bridge. Nonetheless, our determination remains firm," Moore articulated.

The 2024 tragedy stands as one of the most devastating bridge collapses in U.S. history, accentuating serious deficiencies in infrastructure safety and emergency communication strategies. The NTSB's recommendations following this investigation are anticipated to shape future safety protocols for both maritime operations and bridge construction, with the goal of preventing similar events from occurring.

This investigation highlights the critical need for meticulous maintenance of cargo ship electrical systems, prompt emergency notifications, and improved protective measures for essential infrastructure. Families impacted by the collapse continue to mourn the six lost lives as Baltimore confronts the ongoing task of rebuilding one of its key transit links.
