C&O Canal Lift Locks Rehabilitation

Washington, DC
National Park Service – Department of the Interior
Contract Value: 
Year Completed: 

Clark Civil will perform repairs on the Georgetown portion of the C&O Canal, which was built in 1823 and operated until 1924. Upon completion of the project, the National Park Service plans to reopen the Georgetown canal for boat tours.

Clark Civil will dismantle Lock 3 and perform partial repairs of Lock 4, including repointing and stone repairs. The project team will survey stones from Lock 3 before excavating the stones using a remotely-operated, self-erecting crane. The team will then rebuild the foundation and reinstall the stones in the historic grid position. The team also will remove the wood timbers from the canal’s original construction to pour a new concrete mat foundation. The team will rebuild the lock gates to both locks to allow for water and boats to move through the canal.

Clark Foundations is part of the project team and will perform support of excavation.

Construction is underway and substantial completion is scheduled for 2018.
