The bridge is owned and maintained by the Canadian National Railway and is used by Amtrak passenger trains and Canadian National Railway freight trains.[2]
In 2011, most likely due to debris hitting the bridge after the opening of the Bonnet Carré Spillway, 26 feet (7.9 m) of the bridge was damaged and a bridge pier was dislodged.[3]
On February 13, 2016, a fire destroyed over 800 feet (240 m) of the trestle near its southeast end. The damaged segment was quickly rebuilt and reopened to rail traffic on February 20.
