Monocacy Aqueduct, Navigable aqueduct in Frederick County, United States
The Monocacy Aqueduct extends 516 feet across the Monocacy River with seven arches spanning 54 feet each, constructed from granite blocks from Sugarloaf Mountain.
Completed in 1833 at a cost of $127,900, the aqueduct served as a vital transportation link on the Chesapeake and Ohio Canal between Georgetown and Cumberland.
The structure represents a milestone in American civil engineering, designed by Benjamin Wright, who established standards for canal construction across the United States.
Visitors can access the aqueduct through the Chesapeake and Ohio Canal National Historical Park, with parking available near the observation areas.
The structure survived Confederate attempts to destroy it during the Civil War when a local lock keeper persuaded generals to drain rather than demolish it.
