Almost one year later, the collapse of the Francis Scott Key Bridge continues to impact nearly half of all Baltimore-area residents, according to a report by Johns Hopkins University. ​

The safety board issued recommendations as part of its ongoing investigation into the collapse of Baltimore’s Key Bridge last year after it was hit by a ship.

Sixty-eight bridges across the US should be assessed to see if they are at risk of collapse if hit by a ship, transportation safety officials found, while urging the bridges’ owners to undertake immediate vulnerability assessments.
