LILLOOET, B.C. – Crews are entering the final stretch of the Ten Mile Slide stabilization project on Highway 99 in B.C. The province announced the project is now 90 per cent complete, with current work focusing on restoring Highway 99 to two-lane traffic. The project is expected to wrap up this year.
Stabilization work includes the 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.
Officials noted the project’s completion will help increase the safety and stability of one of the most technically challenging roadways in the province.
Government officials explained the site’s complex geological conditions include ongoing slide movement.
In December 2016, the ministry committed $60 million for a long-term fix to stabilize the Ten Mile Slide. Officials stated the total project budget is now $83.7 million, with additional costs adding up due to the project’s complexity.
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. Officials noted the 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.
