March 16, 2020 - Info-Work: Temporary Road Closure

A comprehensive Investigation of the Peterborough Lift Lock has been completed to gain an understanding of the condition of this site as a whole.  This investigation reviewed the site’s geotechnical aspects, structural integrity, equipment and control systems to identify deficiencies, and work needed to ensure the continued safe operation of this asset. 

As a result, work to improve the hydraulic ram seals will begin this fall with commissioning expected in spring of 2020. Future work will also include upper reach concrete repairs and sealing, elevator replacement, earth embankment rehabilitation and mechanical upgrades. Overall, this project will ensure sustainability of Peterborough Lift Lock and increase the overall safety for operators and visitors alike.
