On Saturday at around 6 p.m. PT, DriveBC advised that a single lane of the highway had re-opened, and traffic control crews will be on site to direct traffic; however, the road remains flooded.
The B.C. Transportation Ministry said the flooding spanned over 300 metres of highway and exceeded a depth of more than 75 centimetres at the centreline.
The Ministry closed the highway approximately 80 kilometres north of the community of Dease Lake, and put up signs at both ends of Highway 37, at the Yukon Border, at Kitwanga and at Prince George to inform travellers as conditions change.
There is no detour available, and motorists needing to travel to points north or south were being advised to plan to use Highway 97, which loops around far to the east.
Water levels in the Dease River, which flows out of Dease Lake, are expected to recede over the next two days.
Officials have not posted an expected time of a full re-opening of the route.
