A barge broke loose and struck the I-370 rail bridge near St. Charles on Saturday morning, the U.S. Coast Guard is investigating the incident.
Even though water levels are up, last year’s drought is suspected to have played a role in the accident.
Fallen trees on river banks are normally swept away one by one, but they piled up when water levels shrunk during the drought.
Now that levels are high, a lot of large trees are suddenly floating in major rivers.
