Roebling Delaware Aqueduct

In this upstream view of the aqueduct, the ice breakers can been seen jutting out from each of the three piers. Winter ice flowing downstream hits these wooded abutments and either breaks or is nudged to the side to allow it to flow under the bridge. Without these ice breakers, ice would strike, and build up at the stone piers, severally damaging them over time. While the original stone design contains a form of ice breaker, the wooden abutments complete the original design. For close to 80 years the full wooden ice breakers were not present, and ice was diverted by the angled stone abutments, which took noticeable abuse, but held. The 1990s restoration restored the piers to their original "as built" appearance and function.
