Maryland marked one year since the deadly bridge disaster in Baltimore. Now, the NTSB is urging other bridge operators to conduct critical safety checks to avoid another tragedy. FOX's Caroline Shively reports from Baltimore.

Baltimore’s Francis Scott Key Bridge was at high risk of collapsing if it was struck by a ship, federal safety investigators said Thursday, but Maryland officials never conducted a review — and even lacked the necessary data to do one.

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.
