The ship that slammed into the Francis Scott Key Bridge in Baltimore was re-floated on Monday after being stuck for nearly eight weeks.
The Dali was moved by tugboats "under favourable environmental conditions", according to the US Army Corps of Engineers. Moving the ship is the latest step in clearing key shipping routes. The Dali crashed on 26 March, causing the bridge to collapse and killing six construction workers. The ship lost power before veering off course and striking the bridge. The collision sent around 4,000 tonnes of debris into the Patapsco River and trapped the boat. An investigation into the incident is ongoing. The 948ft (289m) ship had remained at the scene and was covered in scrap metal from the bridge, until a controlled demolition last week cleared some of the debris.
