Walker Bridge Replacement in the West Block of Grasslands National Park

Parks Canada Agency (PCA) proposes to replace the existing Walker bridge over the Frenchman River in the West Block of Grasslands National Park, which is a key access point for park staff, visitors, locals and stakeholders. The existing bridge often experiences ice damage and flooding, which impedes access and requires frequent repairs. The bridge is at the end of its service life and repair is no longer a viable option. The new bridge will be built to withstand 1:50 year flood events and meet provincial hydraulic capacity requirements. Because the grade raise required to achieve this design will interfere with the agricultural operation and houses beside the bridge, the new bridge will be built 120 m west of the existing bridge. Work will include building a new bridge while access is maintained with the old bridge, constructing roughly 500 m of road to connect the new bridge to the existing road, and deconstructing the old bridge. The area around the old bridge and the old road accesses will be reclaimed (roughly 200 m). This project will occur in or near critical habitat for species at risk, including the greater sage-grouse and the loggerhead shrike. The area is part of an active agricultural operation and yard site. Work is planned for 2023/2024. This project will be assessed using a Basic Impact Assessment.
