Although oil has been flowing through the expanded Trans Mountain pipeline since May 2024, the company says it expects to wrap up its post-construction activities this coming spring.

According to the most recent construction update from Trans Mountain, clean-up and land reclamation efforts will continue through the winter in a limited fashion. The final phase of work will fully resume in the spring.

In 91Ô­´´, that means cleaning up right-of-way and access roads, and reseeding, replanting, and reclamation of land along the pipeline route.

Construction of the pipeline in 91Ô­´´ involved building corduroy roads out of timber to give large trucks access to the pipeline site, including along the new part of the route near Telegraph Trail east of Walnut Grove.

Farther east, near 240 Street, construction caused a series of sink holes in 2023. The company said they were the result of "challenging ground conditions" and they were being stabilized.

Although the pipeline is complete, Trans Mountain has applied to the Canadian Energy Regulator (CER) to dig a trench through the Salmon River streambed near Fort 91Ô­´´ in the summer of 2025.

The work is being requested to replace a pipe section to make it safe during earthquakes, and is separate from the spring reclamation work.
