Highway 99 - Ten Mile Slide

Highway 99 is the most direct connection between Lillooet and Kamloops and is vital to the local and regional economy, as well as the Xaxli’p community. This  project will address the slope instability at the Ten Mile Slide location.

The scope of the project includes planning, engineering and construction to implement stabilization measures above and below Highway 99 as well as the reconstruction of the highway.
