The final piece for reconstructing the Ten Mile Slide, located 17 kilometres northeast of Lillooet on the Xaxli’p’s Fountain Indian Reserve on Highway 99, will be completed this coming summer, as paving is planned to occur earlier than initially anticipated, according to the Ministry of Transportation and Infrastructure.
“The Ministry of Transportation and Infrastructure has been monitoring the Highway 99 Ten Mile Slide site closely and confirms the site has settled and is ready for paving ahead of schedule,” a ministry spokesperson said in an email.
“Paving of Highway 99 at Ten Mile Slide will happen this upcoming construction season. The ministry would like to thank Xaxli’p, Highway 99 users and other key stakeholders for their patience while the long-term solution at the Ten Mile Slide site was implemented.”
Paving the final 300 metres of highway ends a several-year-long saga for the area that began in 2016 following a significant landslide that required the road connecting Lillooet to Kamloops to shut down completely for several days. Following the closure the province decided to invest $60 million into stabilizing the road.
The reconstruction and stabilization project required significant engineering resources, 148 concrete and composite piles, and 276 soil anchors. Construction took five years, cost about $83.7 million, and finished in October 2021. The road remained gravel for the next two years to let the earth settle, which is now complete, allowing paving to occur.
