Conococheague Aqueduct Restoration Project

An historic restoration of the Conococheague aqueduct is taking place in Williamsport, resulting in closing the towpath upstream of the Cushwa Basin for the duration of the project.

The project restores the aqueduct piers, “trunk,” and towpath to protect this historic resource. The project also re-waters the canal through the aqueduct, providing a unique visitor experience.The project began in August of 2017 and is expected to require 18 months to complete. Go to the Conococheague Aqueduct Project page to learn more about the construction and the history of the bridge and project. More information is also provided in the Conococheague Aqueduct Restoration Groundbreaking Ceremony press release.

Repair Watered Structures Locks 5-22 Project

Construction is anticipated to begin on or about December 4, 2017 and extend until spring 2019 (weather dependent). Project work will focus on eight different areas between Little Falls and Swains Lock.

Work will take 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.
