Though not on the scale of some pictured here, the Roebling Bridge at Minisink Ford, NY was originally a canal aqueduct over the Delaware River. It used the same suspension cable technology he later used in the Brooklyn Bridge.
Not far from you either...easily in a day-trip drive.

Is it possible that one was built by the Elder Roebling?
