The Monocacy Aqueduct, also known as C&O Canal Aqueduct #2, is the largest of the 11 aqueducts constructed on the Chesapeake & Ohio Canal. Located at mile 42.2 along the C&O Canal towpath near Dickerson, Maryland, it comprises seven arches, each spanning 54 feet. The aqueduct’s length is 438 feet from abutment to abutment. It crosses the Monocacy River just before it empties into the Potomac River. Described as one of the finest canals in the United States, the aqueduct scale is considered a major engineering accomplishment for the time it was built, 1829-1833. Constructed mainly out of large quartzite stone blocks quarried from Sugarloaf Mountain’s base, the stones were carefully placed together and painstakingly hand-shaped by masons once on site. The aqueduct cost $127,900 to construct.
In 1972 after the Hurricane Agnes flood, engineers designed a steel banding system to stabilize the structure and installed steel rods to reinforce it. In 2004-2005, after restoring the Monocacy Aqueduct to its original state, they were able to remove the steel banding system.
