UPDATE: Highway 99 is now open to single-lane alternating traffic after a logging truck caught fire earlier Tuesday.
On Wednesday afternoon, the Resort Municipality of Whistler (RMOW) also provided some more details on the fire, although no cause has been determined as yet.
A spokesperson said the fire spread briefly to some nearby brush, but was extinguished quickly by members from the Whistler and Pemberton fire departments. Contributing to the challenge of putting out the fire was the fact flames were "deep seeded in the logs on the truck," the RMOW said. "The overhead power lines, and risk of the logs breaking free from the truck, made this response challenging. Additionally, we required an extra logging truck to arrive on site to unload the logs, to fully extinguish the fire.
"We are extremely grateful for the swift response by the [Whistler Fire Rescue Service] and Pemberton Fire Rescue members, in addition to the local highway traffic company that was working in the area that assisted with traffic control until the highway traffic control contractor arrived on scene."
Highway 99 north of Whistler is closed due to a vehicle fire, according to DriveBC.
The incident occurred between Heliport Rd and Riverside Dr, about three kilometres north of Whistler.
Drivers are asked to watch for traffic control.
No detour or time of reopening is available, but drivers can check DriveBC for updates.
