MOBILE, Ala. – The Demopolis Lock is closed to traffic for repairs. A breach occurred on Jan. 16, caused by a concrete sill failure. The U.S. Army Corps of Engineers is assessing the failure and processing data to develop repair plans. There is no current estimated time for completion of repairs; updates will be made as more information becomes available.

“Mobile District is working on a comprehensive plan for the Demopolis Lock way ahead,” said Nelson Sanchez, Mobile District Operations Division Chief. “At this point, we are unable to give any timelines or further information as more time is needed to plan our engineering acquisition strategies to determine our courses of action for repairs. We appreciate your understanding and interest to support.”

Current progress updates are posted on the Mobile District’s website:, under the Demopolis Lock & Dam Update.

The Demopolis Lock is the first lock after the junction of the Tombigbee and Black Warrior Rivers. The lock typically experiences 12 daily transits of various cargo, such as feedstock, steel, coal, and crude oil.
