SUMMERLAND, BC — Major blasting to remove unstable material above Highway 97 north of Summerland in British Columbia is complete.

More than 46,500 cubic metres of material has been removed from the slope since August 2023, states the British Columbia Ministry of Transportation and Infrastructure. That stretch of road was first closed following a rockslide on Aug. 28, 2023 when approximately 3,000 cubic metres of material came down. The road was reopened to two lanes of traffic (one lane in each direction) in September of 2023 with intermittent closures for blasting.

With the end of major blasting, which could only be done during daylight for safety reasons, the ministry states crews are working 24-hour shifts with a focus on stabilizing the slope with rock bolting. Smaller blasts may still occur.

The progress is also allowing crews to shorten the length of the construction zone and allow four-lane traffic at the south end of the site from Callan Road to Summerland during summer. Two lanes of traffic (one lane in each direction) will continue through the main slide-area work zone. The Ministry advises drivers to use caution and obey the construction zone speed limits and traffic-control personnel.

The Ministry warns this remains an active slide area and conditions can change quickly. Drivers should continue to check DriveBC for up-to-date information about road conditions and slide closure schedule.
