C&O Canal Tonolaway Creek Aqueduct

Photo of park sign with some history. Titled "A Work Of Art" it reads as follows. "Looking at the remaining iron railings and graceful arch of the Tonoloway Aqueduct, it is easy to see why canal company officials referred to the 11 aqueducts along the canal as "works of art". Built betwen 1835 and 1839, Aqueduct 7 carried the canal across Tonoloway Creek. Time and floods have not been kind to the Tonoloway Aqueduct. Years of carrying water and canal boats took a toll on the sides of the aqueduct, eventually causing it to collapse. Debris carried by flood waters damaged and washed away iron railings. To protect the aqueduct, the National Park Service built steel braces to support the arch and remaining walls."

Another blurb states that "Even in 1863 the Tonoloway Aqueduct suffered from maintenance problems. Leaking water washed away mortar and weakend the masonry."

There is an additional segment relating how an aqueduct actually functions with a diagram.
