Details are limited but authorities are on the scene. Eastbound traffic through the accident area was detoured for about an hour off of Highway 1 via Highway 9 with the help of traffic control.
Traffic heading east on the provincial highway has since reopened, though westbound traffic remains closed as of press time.
Luckily, no injuries have been reported yet, but DriveBC is urging commuters to keep an eye out for traffic control.
