Starting Wednesday, construction crews will be sealing cracks along three different highways in Northern Minnesota in preparation for winter.

According to Mn-DOT, Highway 71, Highway 210 and Highway 10 will be reduced to one-way alternating traffic. Motorists should plan extra travel time as daytime delays are expected.

Construction will begin Wednesday on Highway 71 between Menahga and Wadena. After Highway 71 sealing is complete, crews will start work on Highway 210, then finish sealing on Highway 10.
