On Tuesday, March 26, 2024, the 984-foot M/V DALI allided with the Francis Scott Key Bridge near Baltimore, Maryland, sending the bridge tumbling into the Patapsco River, resulting in the tragic loss of six construction workers, and triggering a local, state, and federal response. Large sections of the bridge’s structure lay across the main shipping channel into the Port of Baltimore closing the deepest shipping lane into and out of the port, and resulting in an estimated loss of $15 million in daily economic activity for the area. All shipping traffic was diverted from the area, enabling first responders to conduct high-priority rescue and recovery operations and allowing highly trained salvage crews to begin the arduous task of removing bridge wreckage. Due to the amount of debris in the water, it was evident that salvage operations would take some time, and the priority at the time was to open the port for at least some vessel traffic.
