The failed Demopolis Lock near the junction of the Tombigbee and Black Warrior rivers in Alabama is expected to reopen 30 May after repairs, the US Army Corps of Engineers (Corps) said today.
A clearer timeline for the repairs emerged after a more general May timeline finish date indicated in February.
Work on the lock has been ongoing since it collapsed in early January. Debris has been fully removed and the Corps is working on tests for the concrete mixture. Contractors are currently installing anchors and formwork.
The Corps expects concrete placement to start in mid-April and finish before the end of May.
The cost of the project to date surpassed $21mn, and could rise further the Corps said.
