Jennifer Homendy, chairwoman of the NTSB, highlighted the need for improved maritime safety standards following the collapse of the Francis Scott Key Bridge after the Singapore-flagged container ship Dali collided with it.Six Latin American road workers died when the bridge fell into the Patapsco River, and investigations revealed that the disaster was preventable due to delayed warnings and electrical failures on the ship.The estimated reconstruction cost has doubled to between $4.3 billion and $5.2 billion, with completion postponed to 2030, and safety recommendations now include thermal imaging and better emergency systems.
