VICTORIA - A major stretch of highway in northeastern B.C. from Mackenzie Junction to Chetwynd is set to reopen, one week after it was closed by severe flooding.

Transportation Minister Todd Stone advises drivers to expect single lane alternating traffic along the nearly 150-kilometre stretch of Highway 97.

He says pilot cars may be needed to lead convoys through some sections of the corridor and motorists should expect the trip to take longer than the usual 90 minutes.

Crews have been working on the route and others in the Peace region since last week when at least 100 millimetres of rain tore up roads, washed out bridges and train tracks, and damaged buildings around Chetwynd and Dawson Creek.

Stone says nearly 200 pieces of equipment have been assigned to restore the flooded routes.

Traffic is moving on Highway 2 south of Dawson Creek and Highway 29 north of Chetwynd, while single-lane travel is also possible on 21 of 40 washed out side roads.
