The Oneida Creek Aqueduct was built over Oneida Creek as part of the Enlarged Erie Canal. The aqueduct is located just west of the village of Durhamville, on the border of Oneida and Madison Counties (Oneida Creek is the border), and was completed around 1856. Very little of the original aqueduct remains, as can be seen from the pictures below. The original wooden trunk and piers of the aqueduct have been replaced by concrete.
Below are pictures of the Oneida Creek Aqueduct taken in October 2005 and Summer 2007. Click on an image below to see the full-size version.
