It’s not a request that Canadian National Demolition (CND) takes lightly, but the safe demolition of part of the former Resolute Forest Products pulp and paper mill in Fort Frances, Ont. required a full overnight closure of the international border crossing between that town and International Falls, Minn. The mill was built in 1912, as was the original private international road and rail bridge, owned by the Minnesota and Ontario Paper Company. The bridge, which remains the only connection between the two communities, is still jointly owned by Resolute Forest Products on the Canadian side and Boise Cascade, which continues to operate a pulp and paper mill in International Falls. The four-phase demolition contract… encompasses more than a million square feet of buildings, three paper machines, a kraft mill, a biomass plant and a co-generation plant.
