The Ministry of Transportation and Infrastructure will be doing a further assessment of the slope stability where a landslide came down onto Highway 97 in Summerland on Monday night.
The Ministry confirmed that an initial geotechnical assessment was conducted before crews began to clear the slide on May 15, but a further review will get underway.
The slide covered a 40-metre-long section of the highway and all four lanes of traffic. The silt and clay hillside gave way abruptly sending material tumbling down onto the road in a large cloud.
In some lanes, the debris was at least eight feet deep.

No vehicles were damaged, but it took from when the slide happened at 7 p.m. until 1 a.m. for a single lane to be opened back up for alternating traffic.
The entire slide was approximately 120-metres long, and it came less than a month after two other slides.
The two smaller slides occurred on April 26 and 28, and didn’t block the highway.

Traffic is still limited to a single alternating lane, and the ministry did not provide an estimate for when the highway will be fully reopened.
“Travelers should expect delays and watch for traffic control,” they advised.
