Construction of the Peterborough Lift Lock lockstation
Constructed: 1896-1904

Superintendent R.B. Rogers advocated a hydraulic lift lock to overcome the 65-foot change in elevation at this site. After examining lift locks in England and Europe, he supervised the 8-year process to construct the walls and towers and erect the metal tubs on steel rams. Built mainly by Canadian companies, it remains a world-class engineering feat and is a National Historic Site of Canada.
