      One of British Columbia’s busiest highways remains closed for a second day after authorities issued a warning about potential landslides in the region.

      “Drivers are advised that Highway 99 is currently closed approximately 15 kilometres north of Lillooet due to ongoing slope activity at the Ten Mile Slide site,” a November 10 Ministry of Transportation and Infrastructure media release reads.

      “Accelerated movement over the last 24 hours at this historically challenging slide site has reduced safety,” it continues. “The ministry has proactively closed Highway 99 between Fountain Valley Road and Sallus Creek Road.”

      The release sates that geotechnical engineers are using electronic monitoring equipment to assess the situation on an ongoing basis.

      “The road will be reopened once movement has subsided and Highway 99 is once again safe for travel,” it adds.

      The release notes that a $60-million “slope stabilization project” is underway at the site where activity has prompted authorities to close the highway. It’s expected that construction work will be completed by the spring of 2021.

      The stretch of Highway 99 that authorities have closed to traffic is the most direct route from Whistler to Kamloops and other cities and towns in B.C.’s southern interior. Landslides in the area are common and have been a problem for traffic as well as tourism and industry in the area for several decades. The goal of the province’s stabilization project is to serve as a permanent solution.

      Until the highway is reopened, drivers are advised to use highways 12, 1, and 97. Updates will be posted at DriveBC.ca.
