The Unified Command team used the crane barge Chesapeake 1000 for some heavy lifting Sunday at the wreckage site of the Key Bridge in the Patapsco River. The Chesapeake 1000 is the largest floating crane on the Eastern Seaboard. The crane is being used to move a large piece of supporting steel from the bridge that will assist in opening a limited access channel that will allow one-way ship traffic to the Port of Baltimore.
