Nearly two months after knocking down the Francis Scott Key Bridge, the container ship Dali is back in Baltimore. The Dali had been resting on the muddy floor of the Patapsco River since the March 26 crash. For most of that time, it was trapped under a portion of the bridge it destroyed, but on May 13, a crew set off controlled explosions to free it, with plans to “refloat” it in a matter of days.
