—Original story—
If you don't have to head south from Squamish or north to the community, you might want to delay your travel.
The Sea to Sky Highway near the Stawamus Chief is shut in both directions.
At about 2:30 p.m. on Good Friday, March 29, DriveBC posted to X that a vehicle incident has closed Highway 99 in both directions south of Squamish at the Stawamus Chief parking lot.
"Crews en route. Drive with caution in the area and expect major delays," the post says.
Other social media reports are that it is due to a multi-vehicle collision and that an air ambulance had landed, but that has not been confirmed by authorities.
Squamish local, Johanna Proudfoot, messaged The Squamish Chief saying the vehicle she is in is stuck in the northbound lane about two kilometres south of Shannon Falls.
"Nowhere close to the front of the line. ... Air Ambulance flew south at 3:18 [p.m.] I’ve been stopped since 2:52 [p.m.] People out of cars. Evidently the stopped traffic is well south of Murrin Park at this time," she wrote around 3:30 p.m. on Friday.
The Squamish Chief has reached out to the Squamish RCMP for more information and will update this story if and when we hear back.
