Drive BC says the Coquihalla Highway between Hope and Merritt, B.C., is now clear after a six-hour closure in both directions that began after 11 p.m. PT, after a vehicle accident.

A strong weather system has brought heavy snow to the area. The accident happened around 5 p.m. near the Zopkios Rest Area. Drive BC says there have been other vehicle incidents as well.

RCMP in the area say multiple semi-trailers ended up blocking the roadway after losing control in the snowy and icy conditions. Officers say there have been no injuries.

On Sunday, Environment Canada issued a snowfall warning for the Coquihalla Highway between Hope and Merritt. Up to 20 centimetres of snow was expected before the storm moves into Alberta on Monday morning.

Pictures online show cars backed up along the roadway.
