Reconstruct/Stabilize Historic Stone Wall & Towpath McMahon's Mill to Lock 42
The park plans to rehabilitate a historic stone retaining wall and stabilize the towpath along a 0.9-mile stretch between McMahon’s Mill (mile 88) and Lock 42 (mile 89) in Williamsport, Maryland. This section of the park is intermittently covered with water during river flooding, causing resource damage and requiring bicycle and pedestrian detours.
Paw Paw Tunnel Rock Scaling and Pinning ProjectThe Chesapeake and Ohio Canal National Historical Park (C&O Canal) is conducting a rock scaling project along the towpath at the northern or downstream portal of the Paw Paw Tunnel (Mile 155.2).
Go to our Paw Paw Tunnel Rock Scaling and Pinning Project page for more information on the project and its scope.
Repair Watered Structures Locks 5-22 ProjectConstruction began in December 2017. As of April 2020, all detours have been removed and only punchlist items remain to complete the project. Project work focused on eight different areas between Little Falls and Swains Lock.
Work took place at the following areas in the Palisades District of the C&O Canal: Swains Lock (MP 16.9 Breach), Great Falls Tavern (Level #20 and Lock #19), Olmsted Island (Lock #18 and Lock #17), Carderock (Culvert #15), Lock #10 (Rock Run Culvert) and Level #7.
These improvements will help the park's historic structures withstand impacts from Potomac River floods and make the features easier to maintain. For more information about the project, visit the Repair Watered Structures Locks 5-22 Project page.
Towpath Resurfacing ProjectVisitors will see towpath resurfacing taking place throughout the park over the course of five to ten years. These improvements will create a smoother, safer visit for the park's nearly 5 million annual visitors. For more information and current work areas, please visit our Towpath Resurfacing Project page.
