The Cowaselon Creek Aqueduct is located in the middle of the Old Erie Canal State Historic Park, on the south side of Canal Street, east of the Village of Canastota and west of the Village of Durhamville, in Madison County. The aqueduct was built over Cowaselon (also spelled Cowasselon, Cowassalon, etc.) Creek as part of the Enlarged Erie Canal, and was completed around 1856 with two spans at 51 feet 6 inches in length. Unlike many aqueducts, the towpath was supported by piers rather than arches. The original wooden trunk of the aqueduct has been replaced by concrete.
