The Duck Creek Aqueduct is located on the eastern fringe of the village of Metamora in their historic district in Franklin County. The historic Whitewater canal is paralleled by Metamora's Main Street as well as railroad tracks. Due to its wooden construction, the aqueduct closely resembles a traditional covered bridge. It is a single-span Burr through truss aqueduct and measures approximately 90 feet long and 25 feet wide, with a structural height of 25 feet. The trough carrying the canal is formed out of oak beams and panels and carries water to a normal depth of 2–3 feet. Water management valves and a spillway at the western end of the structure permit regulation of the water level of the canal. The roof is a 20th-century metal standing seam roof.

The original aqueduct was built between 1839 and 1843 as part of the canal's original construction by the Whitewater Canal Company and Henry C. Moore. The present structure was built in 1846 after the original aqueduct was washed out in a flood. It was strengthened in 1868, and repaired in 1901. After abandonment and deterioration, the Duck Creek Aqueduct was restored to its present appearance in 1946–1949. It has since undergone regular maintenance, including a historically sensitive replacement of the trough in 2005.

Covered bridge aqueducts were never particularly common in the United States. In a nationwide survey conducted for the National Park Service in the 2010s, only ten structures were identified through historical records. The Duck Creek Aqueduct is the only one of these still standing.

Engineers designed this aqueduct to carry the canal and boats above the creek. Canals rely on water that is completely level, otherwise, the water would simply run downhill. To keep the canal level across creeks and other dips in the land, engineers designed aqueducts like this one. Two floodgates on each side release extra water to keep the canal level.

It was listed on the National Register of Historic Places and designated a National Historic Landmark in 2014.
