The 8-mile-long Confederation Bridge links Prince Edward Island with mainland Canada. In the winter, when the water in the strait freezes, the wind and tides can push the floating ice against the bridge, causing the evenly spaced piers to slice the ice into remarkably uniform rectangular chunks.
To put the rectangles into perspective, the bridge piers that are designed to break up the ice floes are 250 meters apart. That distance would also represent the width of each of the rectangles. The length of the blocks varies but, on average, the length is about 75 per cent greater than the width.
It is likely that the Confederation Bridge will have lots of slicing to do this winter. Department of Fisheries and Oceans spokesman, Steve Hachey said ice conditions started developing in the Northumberland Strait earlier than normal this year, resulting in a current thickness of up to 30 centimeters.
