LILLOOET, B.C. – Work will soon begin on the second phase of a $60 million stabilization project for the Ten Mile Slide on Highway 99.
The site, called “one of the most technically challenging sites to maintain in the province” in a government statement, is approximately 17 kilometres northeast of Lillooet on Highway 99 and has experienced numerous slides over the decades in an area that acts as the primary connector between Lillooet and Kamloops and resides within the Xaxli’p’s Fountain Indian Reserve.
“We understand the impact highway conditions have had on the Xaxli’p community, the tourism industry and local businesses. I would like to thank Xaxli’p for working closely with the ministry to advance this project, which will mean safer travel through the area for years to come,” B.C. minister of transportation and infrastructure Claire Trevena said.
The main stabilization contract was recently awarded to Flatiron Constructors Canada Limited. Stabilization will involve installation of tied-back concrete and composite piles below the highway along with 200 soil anchors above the highway and reconfiguration of the road as two lanes with a guardrail.
The first phase of stabilization was completed in February 2019 and included installation of 44 soil anchors, with load restrictions increase to 27,000 kg gross vehicle weight (GVW) once geotechnical assessments were made and the work was completed.
“Consultation with Xaxli’p, other stakeholders and the public has been ongoing throughout the process and will continue until the $60-million project is completed,” the government statement said.
