LILLOOET, B.C. — BC Ministry of Transportation officials say they think they have a temporary solution that may have Highway 99 north of Lillooet partly open by later this week.

The route has been closed since last week, when officials noticed the historic instability at 10 Mile Slide had become worse, causing the foundation beneath the mountain road to crumble.

Regional Director Mike Lorimer says crews are working this week to move the road away from the cliff edge.

“If you can picture the road cut into the side of the mountain, we are going to move the road a little further into the mountain, carve out some of the materials so that we can create a lane that is on more stable ground. We are going to see how the slide responds to that, whether that changes things, if it makes the movement increase again or not. We are optimistic that we are going to have a positive outcome,” explained Lorimer.

Lorimer says this is a short term solution, but the ministry is closing in on a potential longer term solution that could keep the road stable for 30 to 40 years.

“Getting back to some level of opening, it will give them access to work, to services, and make sure that emergency services can get through. It is what we want to get to, obviously we are going to put safety first. We have seen some good indications out there.”

He notes the earth flow will always exist, so there is no permanent fix.

“They are never going to fix this site permanently. This is not the kind of site that you can fix permanently. From the Fraser River to halfway up the mountain, you’ve got a massive earth flow that is always going to move.”
