Pictures from the provincial Ministry of Transportation and Infrastructure shows the extent of damage to the Coquihalla Highway between Hope and Merritt.
Damage was caused as a result of flooding and mudslides following storms Sunday and Monday.
Officials say they can't even hazard a guess at when Highway 5 will reopen.
It is likely that the BC Interior will have to rely on Highway 3, the Hope to Princeton, to access the Lower Mainland. That link is hoped to open next week.
