Tonoloway Creek Aqueduct
Canal Aqueduct
The Tonoloway Creek Aqueduct--officially Aqueduct No. 7 on the C&O Canal--was completed in 1839 and stands as one of the canal's most distinctive pieces of masonry engineering. Built of locally quarried limestone, much of it taken directly from the Tonoloway Creek valley, the structure was designed by Chief Engineer Charles B. Fisk and constructed by contractor John McCartney during a period when the canal company was racing to push westward toward Cumberland. The aqueduct carried canal boats across the rocky gorge of Tonoloway Creek on a single graceful arch, and despite floods, ice, and the financial turmoil that plagued the canal, it remained structurally sound throughout the canal's operating years. Today, the aqueduct survives as a remarkably intact example of 19th-century stonework.
