UPDATE:The ministry closed Highway 99 north of Pemberton last night "out of an abundance of caution at the recommendation of ministry geotechnical experts," reads an emailed statement from the Ministry of Transportation and Infrastructure.
"Highway 99 has known slide paths—and heavy rains were forecast last night. So the ministry made the decision to close," the statement reads.
"Fortunately, there were no slides or debris overnight. Staff assessed the highway at first light. There are no further safety concerns, and the road was reopened at 7 a.m."
The existing avalanche closure gates were used to prevent drivers from using Highway 99 during the closure, which lasted from 8 p.m. Monday night to 7 a.m. Tuesday morning.
