Key Bridge Rebuild/MV Dali Back Is Back/URGENT NTSB Warning

Jeff Ostroff continues the analysis and investigation into the Motor Vessel Dali collision with the Francis Scott Key Bridge in Baltimore, MD on March 26, 2024, with updates now that Dali is back in action after repairs. Also, the new Francis Scott Key Bridge redesign is in full swing and the design will be analyzed. The NTSB also held an urgent press conference this week to warn of 68 major bridges that might be at risk of collapse after collision with a ship. NTSB also implicated the Maryland Department of Transportation in failing to run a risk assessment analysis on the Key Bridge, and they might have seen that the bridge failed the criteria by 30x.
