Sonar helping to map debris from Key Bridge collapse

Gov. Wes Moore said salvage operations involves the use of technology to map the site of Baltimore’s collapsed Francis Scott Key Bridge. The governor said Wednesday’s unified command briefing indicated Wednesday’s weather conditions made it unsafe for rescue divers to return to the water. “The water is so murky that salvage divers cannot see more than two feet in front of them,” Moore said.”It’s cloudy because of the 4-5 feet of mud and the loose bottom of the river, divers are working basically in darkness,” said Col. Estee Pinchasin, District Commander for the Army Corps of Engineers, Baltimore District. “If they use lights, if we lit it up, it would be like they were driving through a snowstorm with their high beams on.”Officials said they are ready and waiting to start lifting non-impacted containers off of the Dali cargo ship, once the weather allows.”We need to lift those undamaged containers off to give us space to safely operate to begin to plan to remove portions of the bridge that are also now embedded in the ship,” U.S. Coast Guard Rear Admiral Shannon Gilreath said. “On our third priority, which is removing the rest of the debris from the bridge, from the waterway, we are again waiting for another weather window to be able to do that 350-ton lift off the section that’s just immediately north of the deep draft channel.”Authorities said there is 3,000 to 4,000 tons of steel on top of the cargo ship. The U.S. Navy’s Naval Sea System Command Supervisor of Salvage and Diving released new 3D underwater images of the site on Tuesday. They show the sheer magnitude of the salvage operation ahead.
