A multi-vehicle crash has shut down the Sea-to-Sky Highway in both directions on the way to Whistler, B.C.
RCMP say poor weather is contributing to the road conditions and drivers are being asked to avoid the area.
Police say in a news release that the crash happened between Callaghan Valley and Brew Creek roads on Wednesday.
Cpl. Katrina Boehmer with the Sea to Sky RCMP says there will be extensive delays until the investigation can be completed and the road is re-opened.
10 have been injured and 2 are in critical condition.
The department says it has asked for the help of the collision analysis and reconstruction service, and there's no estimate when the highway will open.
