The Fraser Highway through Langley was closed between 248 and 260 Streets because of downed power lines all day Saturday.
Traffic was still not moving by early evening, despite reports that the route was to re-open by 6 p.m.
It was one of several cases of power lines coming down during an overnight storm that cut electricity to tens of thousands of BC Hydro customers, with most of the outages reported in Langley, Abbotsford, Mission and Chilliwack.
Environment Canada had issued a freezing rain warning for southeast Metro Vancouver, saying a strengthening storm just west of Washington State would be sending warm, moist air into the Fraser Valley region, causing freezing rain in areas throughout the area.
Conditions are still hazardous in the #FraserValley, including some areas with fallen trees and trees on our lines. Remember: down, danger, dial. Stay 10 metres back from fallen lines or trees on lines and call 911. pic.twitter.com/uBwCcFz5xg
