A mudslide has closed Highway 1 in B.C.'s Fraser Canyon on Wednesday night.

DriveBC says a mudslide has shut down the Trans Canada Highway in both directions between Lytton — located about 150 kilometres northeast of Vancouver — and Spences Bridge, from Highway 8 to Highway 12.

There is no detour available and a slope assessment will be conducted at first light, DriveBC said.

Witnesses say it was pouring rain before the mudslide hit the road.
