A $6.7 million construction project will soon be underway to improve several locks, waste weirs, bridges and other water control structures between Little Falls (Lock #5) and Swains Lock (#22). These improvements will help the park’s historic structures withstand impacts from Potomac River floods and make the features easier to maintain.
Construction was anticipated to begin about December 4 and extend until spring 2019 (weather dependent). Project work will focus on eight different areas.
To provide safe access to the work areas, the canal will be drained in these areas at various times throughout the project. Draining operations began November 26. Precautions will be taken by the park to protect wildlife within the canal during these operations.
This project consists of work in the following areas: Swains Lock, Great Falls Tavern, Olmsted Island, Carderock, Rock Run Culvert, and Lock #7. During construction, visitors will be directed to follow easily navigable detours around the work areas.
