Ten Mile Slide Project Moves into Second Phase

The Province of B.C. has announced phase two of the project to stabilize the Ten Mile Slide site on Highway 99.

Phase one, including advanced soil anchor work, was completed in February. The phase 2 tender closed in July and construction is expected to begin in late summer.

The Ten Mile Slide is approximately 17 kilometres northeast of Lillooet on Highway 99. This stretch of highway has experienced ongoing slide activity for several decades. Highway 99, which is vital to the local and regional economy, acts as the primary connector between Lillooet and Kamloops.

The phase two main stabilization work includes the installation of tied-back concrete and composite piles below the highway, 200 soil anchors above the highway and reconstruction of the highway to two lanes with a guardrail.

The main stabilization contract was recently awarded to Flatiron Constructors Canada Limited and the work is expected to be completed in spring 2021. Ministry staff will continue to monitor the slide for approximately two years before paving the new section of two-lane highway.

During construction, drivers can expect delays and temporary closures.
