A recent aerial shot (bottom) of the 12.9km long Confederation Bridge (top) linking Prince Edward Island to mainland New Brunswick in Canada showing surface ice in the frozen strait neatly sliced into rectangles by its evenly spaced piers. To wit:
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.
