Baltimore's Francis Scott Key Bridge collapses after container ship collision - 6 workers killed

A container ship strikes a support column of the Francis Scott main Bridge in Baltimore, Maryland, causing the bridge to collapse in seconds. Six construction workers filling potholes on the bridge are killed. The collapse shuts Baltimore's port, the largest importer of vehicles in the U.S. and a critical hub for construction equipment, indefinitely, disrupting supply chains. Biden surveys the wreckage and pledges federal support to rebuild quickly. The Coast Guard and Army Corps of Engineers begin a massive operation to remove the 4,000-ton vessel and debris. Congress approves $60 million in initial emergency aid.
