The Ten Mile Slide stabilization project on Highway 99 is now 90% complete, with current work focusing on restoring Highway 99 to two-lane traffic.

Stabilization work includes:

• installation of concrete and composite piles below the highway to support the roadbed and prevent further movement;
• soil anchors above the highway; and
• reconstruction of the highway to two lanes.

Once completed, this project will improve the long-term safety and reliability for people travelling through the Ten Mile Slide area of Highway 99, one of the most technically challenging roadways to maintain in the province.

Due to complex geotechnical conditions at the site, including ongoing slide movement, construction is anticipated to finish in late 2021. The ministry understands the inconvenience this delay will cause and continues to work closely with the contractor to complete the project as soon as possible.

In December 2016, the ministry committed $60 million for a long-term fix to stabilize the Ten Mile Slide. The total project budget is now $83.7 million, with the additional costs reflecting the complexity of this project.

Consultation with Xaxli’p, stakeholders and the public has been ongoing throughout the process and will continue until the project is completed.

Ten Mile Slide, which is located within Xaxli’p’s Fountain Indian Reserve, 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.

During construction, drivers can expect delays and temporary closures and are encouraged to check DriveBC for travel information. Motorists are to obey traffic control persons' direction and posted speed signs when travelling through the work area.

Provincial construction sites have protocols and policies in place following the requirements of the provincial health officer to help prevent the spread of COVID-19. These measures include physical distancing and other protocols to ensure worker and public safety.
