The Coronado Bridge is one of dozens of U.S. bridges that have not yet been assessed for risk of collapse in event of a vessel crash, according to the NTSB.

Coronado Bridge is one of 68 bridges identified by the National Safety Transportation Board in need of assessment for risk of collapse.

The National Transportation Safety Board (NTSB) is calling for a vulnerability assessment of 68 bridges across 19 states, including the Coronado Bridge, a year after a massive vessel hit and caused the collapse of the Francis Scott Key Bridge in Maryland.
