NTSB has launched a go team to investigate the collapse of the Francis Scott Key Bridge in Baltimore. ​

On March 26, 2024, about 0127 eastern daylight time, the 984.3-foot-long Singapore-flagged cargo vessel Dali​ reportedly lost power while transiting out of Baltimore Harbor and struck the Francis Scott Key Bridge in Baltimore, Maryland, resulting in the bridge collapsing and damage to the vessel. ​A portion of the collapsed bridge remains across the vessel’s bow, and the vessel remains in the vicinity of the bridge pier. No pollution has been reported at this time. Initial damage estimates to the vessel and the bridge exceed $500,000.

This accident was classified by the US Coast Guard as a major marine casualty. NTSB will lead the investigation, and the Office of Marine Safety will investigate and establish the probable cause.
