The ship that struck and destroyed a Baltimore bridge on Tuesday morning, snarling commerce on the US East Coast, has a checkered history, including at least one earlier collision and propulsion worries.
It’s still not clear what caused the Dali to smash into the Francis Scott Key Bridge, but video footage showed nearly all of its lights going off shortly before impact. The incident is proving disruptive for shipping at one of the busiest ports on the US East Coast and also for road transport, as it severed a key link on the major highway encircling Baltimore.
