The largest crane on the US eastern seaboard has been called in to help clear the wreckage of Baltimore’s collapsed Francis Scott Key Bridge. Shipments in and out of one of America’s busiest ports are suspended while the wreckage hangs over the cargo ship that crashed into it. Crews were still surveying the damage as of midday on Friday 29 March and a search for the bodies of four workers remains on hold because of the dangers of diving amongst the wreckage. The crane, which can lift up to 1,000 tons, arrived late Thursday night and is expected to start hauling debris out of the water on Saturday morning. A cargo ship crashed into the Key Bridge early on Tuesday, sending the structure tumbling into the Patapsco River.
