The National Transportation Safety Board is urging Louisiana's transportation department to assess the safety of eight of its bridges, including almost all of the bridges crossing the Mississippi River in the state.

A new NTSB report warns that 68 bridges nationwide, including six in Louisiana, may be at risk due to increased ship traffic and structural vulnerabilities.

The US National Transportation Safety Board has issued a warning to bridge operators, telling them to conduct essential safety checks to avoid another tragedy like the Baltimore Bridge disaster nearly one year ago.
