A landslide shut down the Sea to Sky Highway in both directions near Lions Bay Saturday morning.
There have been no reported injuries thus far, according to local RCMP, who say emergency crews are working to assess damage and confirm if anyone was hurt.
A geotechnical assessment is being performed via helicopter, transportation officials said.
Drivers caught in traffic posted photos to social media showing a pile of trees blocking the road.
Police say the highway is not expected to open back up until midnight, and there are no detours.
Wind warnings from Environment Canada are in effect for most of B.C.’s South Coast Saturday, with forecasters saying to expect up to 100 km/h gusts.
This is a developing story and will be updated.
