Ministry of Transportation and Infrastructure - Culvert Replacement Columbia Valley Road

The scope of this project is to remove and replace a severely damaged corrugated steel pipe culvert. This culvert carries Hatchery Creek underneath Columbia Valley Highway and into Sweltzer Creek. To ensure the project is meeting current environmental standards, including for fish passage and climate change resilience, the proposed culvert is a 2.7metre tall by 1.8metre wide concrete box culvert, with a weir-pool fish passage design which will be installed in sections.

To limit the risk of environmental impacts during construction, the proposed alignment is directly adjacent to the existing stream and culvert location. This approach allows for a significant portion of the work to take place outside of the wetted perimeter, limiting disruption to the existing stream channel during construction. The stream will continue to flow through the original culvert until the new culvert is in place. Upon completion, Hatchery Creek will be re-aligned at the inlet side of the culvert and the original culvert will be removed with a portion on the inlet and outlet sides transformed into a habitat area for salmonids and pacific giant salamander. 


Construction of the new culvert will include removal of the existing road and base fill using an excavator. The box culvert will be placed in the excavated area using a crane. Tie in of the existing channel into the new stream will be done under the supervision of a qualified environmental professional, following fish salvage activities.
