DOTD tested the locks on Sunday and Monday, allowing boat traffic to pass while final adjustments were made. The Ostrica Locks are now in normal operation 24 hours a day.
"They've been working on the locks for more than four years," Plaquemines Parish President Billy Nungesser said. "Since it was a state project, we did not have control over it; all we could do was complain and put pressure on them. They met many challenges such as high river and water damage that dragged the project out.
"We're very happy to have Ostrica Locks back open so it can be used to navigate to oyster beds and fishing grounds."
