Photograph of the Delaware Aqueduct, also known as the Roebling Bridge, looking down the deck. The aqueduct was constructed on the Delaware and Hudson Canal in 1848 to carry the canal across the Delaware River.

The aqueduct is located within the Upper Delaware Scenic and Recreational River boundaries and was periodically restored by the National Park Service in the 1980s and 1990s. The aqueduct is a designated National Civil Engineering Landmark.
