In this photo provided by the U.S. Coast Guard, demolition crews begin cutting the top portion of the north side of the collapsed Francis Scott Key Bridge into smaller sections for safe removal by crane in the Patapsco River, in Baltimore, Saturday, March 30, 2024. Salvage teams used an exothermic cutting torch to systematically separate sections of the steel bridge, which will be taken to a disposal site.
