Petawawa Centennial Bridge (Construction Time-Lapse)

A bridge was recently built in Chalk River, Ontario using the latest methods of wood construction. Chalk River is home to Canada’s oldest operating research forest — the Petawawa Research Forest. The recent failure of three culverts left part of the forest inaccessible, which created the need for a bridge. The following is a time-lapse video of the bridge being constructed.

Scientists have declared war on this destructive insect, waging battle on several fronts to protect our ash trees.
