Roebling's Delaware Aqueduct

Location: Minisink Ford, NY, USA
Date: 1848
Creator(s): Roebling, John

The Delaware Aqueduct provided an important transportation link between the Pennsylvania's coalmines and New York's booming industrial marketplace. It is the earliest surviving work of John A. Roebling, who designed the Brooklyn Bridge  30 years later. The cable anchorage system first used on this project was also used on the Brooklyn Bridge. The aqueduct is patterned after Roebling's design of the Pennsylvania Canal over the Allegheny River, and is the oldest metal strand cable suspension bridge still standing in the U.S.

Built as a suspended aqueduct for barges to cross above the Delaware River, the structure was used for this purpose until 1898. The aqueduct was then dewatered and its oak- timber trough was converted to a highway toll bridge.
